  1. I drove my car again for another 30 km of spirited driving with lots of turbo boost and there was no coolant missing.. I am starting to believe that the problem lies in the header tank.. Attached is a photo. When we fabricated a metallic coolant tank , my mechanic asked me if we wanted to retain the sensor and I insisted we do.. If you look closely, there appears to be red coolant on the plastic indicator, so maybe I should do away with this and just plug this opening too..

  3. Update : So today I drove my Esprit V8 around 30 km of combined traffic, highway driving and spirited driving, and guess what, the car performed perfectly and not a single drop of coolant was missing... I am starting to understand what is going on.. When I am driving with a group of more modern sportcars like Porsche 997/991 and want to keep up, or I have a passenger I want to show the capabilities of the Esprit V8, I tend to drive more aggressively pushing the turbos and the engine limits and this sometimes might lead to a little cooling fluid loss... Not sure where it is going.. It could be a) head gaskets b) turbos or c) from the custom header tank which I fabricated and I foolishly installed the stock coolant indicator (My mechanic wanted to make the coolant tank simple with one screw type cap, but I insisted that we also make room for the stock plastic indicator)... So for the time being I will just avoid pushing the car to its limits, and drive it as I always do and enjoy it without any problems..
  4. Sorry, I have been super busy with work... I plan to take the car to my mechanic as soon as I get some time off work and he is available..
  5. I checked the oil and it looks ok... I will go one of these days to my mechanic to check the coolant circuit.. I think he builds pressure to the system with the engine off to see any leak.. John's system looks cool and I also plan to use it to determine what is going on.. I will keep you posted..
  6. I will definitely check to see where the coolant is going.. In the meantime, how do you explain the fact that I can go for 3 weeks without any coolant leak (checking the tank each week) under normal driving conditions... And if I push the car and drive it hard it could lose coolant.. Is the coolant loss related to fast driving (when the engine is under load or the turbos are forcing pressure) so that coolant is lost when the car had been driven fast ?
  7. Hi to all, It's been a while since my last update and things have been going pretty well with the car.. I rebuilt the V8 engine with CP Carrillo Pistons, original Lotus head gaskets, APR head bolts, installed Scotch key on the belt pulley for safety, and also rebuilt the turbos.. Everything has been going well, until last Monday when I drove the car and when stuck in traffic, it started to overheat at 110-115 Celsius.. When I pulled over and let the car cool down, it was missing 2 liters coolant, which I added. I drove the car for a week at night and pushed on the turbos, and when I checked yesterday it was missing 700ml coolant.. I am under the impression that the car loses coolant when I drive it hard and push the turbos beyond 4500 rpm... Could the head gaskets after 4000 miles since the rebuild be leaking? Could coolant be leaking from the turbos ? Thanks
  8. @ProAlloy-Alex Hi !! Can you please explain what is different for US Specification cars ? Thanks !!
  9. Based on my mechanic, we found the PRV stuck open.. Fortunately this happened at low rpm. Immediately I saw the oil pressure light come on and slowed down, but it was too late.. I knew something was wrong, the metallic noise, so I towed my car to my mechanic where immediately he diagnosed a failed conrod bearing.. The bearing that failed was the one further away from the oil pump.. My mechanic said it would have been worse if a piston had seized.. The verdict was that the previous owner had not changed oil regularly and as a result the PRV accumulated dirt and got stuck open. Of course we replaced the PRV with a new one, and I also installed an oil pressure gauge, since the 2001 cockpit only has water temp..
  10. @Joey4420 when my Oil Pressure Release Valve (PRV) failed and my engine suffered from oil starvation causing a spun conrod bearing, I had to dismantle and rebuild the engine. I had to replace a lot of parts, including new oil pump, head bolts and head gaskets, which are not cheap.. Furthermore, the labor was going to be expensive.. So I decided I had my one and only chance to upgrade the cast pistons with CP Carillo forged items.. The price was right, and I decided to go ahead and do so.. My crankshaft was repaired and rebalanced based on the new pistons, and I am very happy now to know that my car has forged internals (the conrods are already forged steel, so is the crankshaft forged steel)... So, even though I work with stock turbo pressure (I rebuilt the turbos, fitted K&N air filters, deleted cats and muffler - just straight pipes, and put Sport 350 ECU) I am very happy to know that my car now has much stronger internals than when it left the factory.. Just think that you get your one chance to put those pistons.. Of course you decide, but this is my opinion..
  11. My understanding is that turbocharged cars like the Lotus Esprit V8 twin-turbo warm up their oil and water faster than Normally Aspirated cars... This makes sense because the two turbos basically work like heaters for the fluids of the car... In the winter months, November-March here in Greece, when I want to go for a quick spin in the evening after work I will usually choose the Esprit, because among the other reasons that make the car great, it warms up faster.. My Ferrari 360 Modena for instance, takes forever to warm up, and if the weather is cold and I don't plan to drive very far, it doesn't have enough time to warm up and therefore cannot enjoy a spirited drive.. In the summertime with high temperatures, thing work the opposite way... On warm summer days, the Lotus Esprit V8 is kept at the garage, as performance drops and there is likelihood of overheating when driving.. The Ferrari is more suitable to warm weather...
  12. Coming back to the Esprit V8 issue, I changed the rears with Michelin Pilot SuperSport 285/35/18 And now I am looking to change the front. Unfortunately Michelin does not produce 235/40/17 So I am looking between Michelin Pilot Sport 4 or Michelin Pilot Sport 4S (I think I will go with 4S which is the replacement for SuperSport) , but the size is 245/40/17 Do you think it is ok to go with 245/40/17 front as opposed to factory 235/40/17 ? P.S. There is a small chance the 245 Sport 4S are not available in my country... and I will have to go with 245 Sport 4... Is it okay ??
  13. Both DHL Greece (terrible way they handle business) and of course Brexit, which in the end will mostly hurt UK business... Already planning to buy parts for my Ferrari directly from Italy (before it was Eurospares) and Porsche directly Germany (before it was or Eurospares)... In the end 145 million customers might turn their back to the UK.. bad for business If the limit for tax/duty free imports is 22 Euros and this includes the shipping cost, in this situation the shipping cost alone is 25 GBP, so basically there is nothing that is exempt from tax/duty which is crazy... For imports from the US the same 22 Euros limit applies, but I know it is not including shipping... So basically the Greek government or Greek DHL messed this up...
  14. UPDATE on Brexit and DHL : Before I placed the order of the small Nylon / plastic part for the Esprit window (each costs 7 GBP) , I had done my research that anything below 22 Euro goes through customs without taxes.. So imagine my surprise when on Friday they call me from DHL to tell me that my order has arrived in Athens and I have to pay duties.. I explain to them that my total order is 14 GBP (I ordered 2 pieces of 7 GBP) which is below 22 Euro.. And then they tell me that I have to look at total cost including shipping, which in this case was another 25 GBP.. At that point I knew they were defrauding me... I asked for their supervisor but they declined.. So I asked them what I had to pay... "To begin with, you have to pay 45 Euros for the documents and fees...." As soon as I heard this I told them I don't accept the charge.. And they suggested they would send it back to sender free of charge.. I agreed and asked very politely the supplier to send it to me via regular ground mail, which would completely bypass customs as low value items.. The nerve of these people... Asking another 45 Euros for and order of 14 GBP.. Something that costs less than 2 GBP I would end up paying almost 90 Euro !!! Crazy... All this due to Brexit... Bad decision indeed...
  15. @v8GTmac1 Nice work !! Wish the gauge was more accurate, there was trip computer that showed remaining range, or the fuel tanks had larger capacity because I find myself very frequently at the gas station pouring in just 50 liters to be safe.. After the engine rebuild on my first long distance run, coming back I had covered 275 km and as I was approaching my house <3km the engine died and would not start again at the traffic light... I thought that the engine rebuild had failed, but I had just ran out of fuel... LOL
  16. @LotusFella Check out my solution : I bought from a pre-1998 Lotus Esprit V8 the Turbo and oil Pressure gauges together with the sender units, and for a 1995-1998 Lotus Esprit S4 the oil temperature gauge and sender unit... The first two the facia at night was red colored, white the third had green light... I could not change the first two colors, so i made the third one red too... I installed an extra pipe to install factory OEM low oil pressure sender, NEW oil pressure gauge sender and NEW oil temp gauge sender.. I didn't want to mess with the clean look of the 2001 V8 dash, so I installed them below the climate control switches.. Check out below
  17. @Bibs Just spoke with DHL. They said that my order will be processed through customs but anything below 22 Euros is free of duties and taxes... So this time I am lucky.. In the future I hope SJSpor**** and PN* open stores in Europe so that we don't pay extra taxes for larger orders...
  18. BOV update : So today I went to my mechanic and took out the BOV to check them. They seem to operate normally, but the spring was kinda hard. We opened them up and and saw that there was a blue spring. I called the distributer of Forge BOV and he said that Blue springs are hard and operate over 1 bar. He said I should go for Green Spring that opens around 0.6-0.7 bar. Before I go, my mechanic put back the BOV and we tested the car... Guess what ? They opened normally under Full Open Throttle. Check out the videos below. My mechanic said that I probably cannot hear them when I drive because a) I have removed the cats and mufflers so my car is too loud , b) when you put the luggage area panel and the engine cover back and close the hood, there less of a chance sound coming from the BOV. He explained to me that Japanese rice cars run 1,5-2 bar pressure with large BOV and that's why they sound loud... LOL
  19. @sailorbob guess what ? You were right 100%. This small plastic part was broken. If found it in the UK for 7 GBP and ordered 2 pieces, because I figured the other side might break soon. Add 25 GBP for fast shipping... and for 2 small pieces that cost no more than 0.50 GBP I am paying 39 GBP... Let's see now with Brexit if there are going to be extra taxes.. I hope not for such small value items... My friend that ordered parts for his Ferrari from Eurosp***** he paid another 35% almost taxes and VAT.. That sucks..
  20. @mike_sekingerjust came back from my mechanic.. unfortunately he doesn’t have infinite free time like me.. So he will do both the window and the BOV on Monday.. I’ll keep you posted.. Only good thing is that the temperature has fallen and it is ready for snow.. So the turbos are running very very well with lots of bang bang.. So I get to enjoy the car.. (Brexit is bad for us, because everything now gets through customs and we have to pay extra.. Lets hope I don’t have to replace whole window mechanism)
  21. @mike_sekinger thank you !! I am going now.. While I am at it I will remove the BOVs too, if my mechanic has time..
  22. @mike_sekinger I need your expert assistance.. Today something happened with the driver's window and I am going tomorrow to my mechanic to check it out.. Any advice how to dismantle / remove to door trim to check the window mechanism ? Thanks !!
  23. @mike_sekinger my close buddy insisted that I go buy softer springs for my BOVs and he gave me the address of the Forge importer here in Athens.. Since I have infinite free time as my businesses are closed due to covid, I drove there with my Lotus today. I showed the guy at the Forge shop my car and he offered to sell me 2 sets of springs (green, yellow, blue, red) for 30 Euro each. He said he does not sell individual springs.. But he insisted that maybe something else is wrong with my BOVs.. Maybe the piston is stuck.. He suggested that I bring the BOVs to him, which is difficult for me, since I cannot do anything mechanical by myself, need my mechanic.. LOL On a another BOV he has at the shop, He showed he how a functioning BOV should work. He pushed with one finger the BOV and used the thumb to close the vacuum opening to see if the BOV would stay open.. So I am going to my mechanic to remove the BOV and test them.. I asked if he could sell me the two kits of springs and allow me to return them to him if I don’t need them.. He said hmm no.
  24. Today as I tried to lower the driver’s side window, it appeared like it tried to rotate and after 1-2 inches it got stuck on an angle.. It was possible to raise it again.. and after a few attempts if I applied a little pressure on the side towards to rear of the car, it would lower normally.. what is wrong ? Is it easy fix ?
