  1. 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
  2. @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 k
  3. 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 doe
  4. 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 ??
  5. 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 Porscheshop.co.uk 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
  6. 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
  7. @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
  8. @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 instal
  9. @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...
  10. 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
  11. @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..
  12. @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)
  13. @mike_sekinger thank you !! I am going now.. While I am at it I will remove the BOVs too, if my mechanic has time..
  14. @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 !!
  15. @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 difficu
  16. 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 ?
  17. Every time I go to the fuel station it takes me for ever to fuel my Esprit V8.. I understand that the fuel tank is split it 2 tanks and there is a hose connecting the two, so it takes extra time for the fuel to move from one tank to the other.. Furthermore, I recently replaced the fuel gauge, but still it is fairly inaccurate when the fuel is low.. It shows zero and then jumps up to 10%.. Too risky not to fuel up.. I have never been able to put more than 50 liters, even thought the tank says it can carry 70 liters.. Also with 50 liter I can do around 125 miles / 200 k
  18. @v8GTmac1 since you enjoy the videos so much, here are 2 new ones my friend took chasing my Esprit V8..
  19. @v8GTmac1 The boost drops during the pull because I lift the foot of the throttle pedal as the revs go past 5500 rpm to prepare myself for the upshift... The is little room left not to over-rev the engine LOL .. So I assume as I lift the pedal boost drops.. I am used to revving my cars, especially my Ferrari that revs to stratospheric 8500 rpm.. 😉 @cweeden The roads here are so slippery... there is wheel spin.. also notice the bang as I upshift.. It is explosion and flames from straight pipes LOL
  20. So basically the article says that at full open throttle there is no chance of air escaping from the BOV as the air pressure is the same before and after the valve.. If the spring is not strong enough the BOV could open at idle or part throttle as this can cause erratic operation of the engine or stalling.. I have to check 1) the connection of the BOV to the manifold and 2) the actual operation of the piston of the BOV Can someone explain the Open Loop vs Closed Loop operation of the Esprit ? Is it true that at >95% throttle openings it works as Open Loop which means it does
  21. You are right I need to take them apart and check if they are working.. I say a small pipe that leaves the T-connector between the two BOV and goes somewhere round the intake manifold.. I will check with my mechanic.. By the way, is there any chance of BOV to open under full acceleration ? My understanding is that when the throttle body is open there is zero pressure difference, so no way to activate BOV.. is this correct ? And another question.. If I fix the BOV and they operate correctly, should I expect better response when upshifting ? Does this mean that the turbo pressure
  22. I decided to start a thread about the Blow Off Valve on my Esprit V8. The previous owner had installed a set of 2 Forge BOV and it appears they almost the same as those sold on PNM. https://www.pnmparts.co.uk/dump-valve-kit-v8-8928 The problem I have is that I believe that in my car a) maybe the BOVs are opening sometime under acceleration (is this possible ?) b) they don't open when I release the gas pedal to blow off the air and allow the turbos to spool freely For a) I hear sometime something like a hissing sound.. not sure if it is the turbine spooling,
  23. I am positive that it is a piston BOV.. My mechanic cleaned them up and showed to me how they work.. I will try to find put more info about them and maybe changed the spring.. P.S. Happy New Year to all !! Today I was driving with fair cool weather and was getting lot of thumbs up from bikers and other motorists.. Guess they love the shape, sound and flames shooting show of the Lotus Esprit.. p.s.2. Funny fact of the day, in the Department of Transportation of Greece some “genious” put in the database that Lotus makes the Lotus Espiri, so all Lotus Esprit cars registed in Greece a
  24. Is there some test to check if my Forge BOV are working properly ? Do you know if they are adjustable ? Thanks
