MD355 Posted January 10, 2020 Author Report Share Posted January 10, 2020 No damage to paint !! When the hood was unlatched/without safety engaged the pop-up light both went up normally !! As soon as I put the safety lock for the front trunk, apparently this would tighten / slightly move to hood down and to the front of the car and it would hinder the normal operation of the right light, which would pop half way. Now all fixed !! 1 Quote Link to comment Share on other sites More sharing options...
andyblackman777 Posted January 10, 2020 Report Share Posted January 10, 2020 I wonder how the crown wheel broke....... Quote Link to comment Share on other sites More sharing options...
MD355 Posted January 10, 2020 Author Report Share Posted January 10, 2020 I wonder too... It happened March 2019, all of a sudden at low speed driving in 1st-2nd gear coming out of a roundabout, a little aggressive on the throttle... As soon as I heard the noise and resistance to rotate, I knew something was wrong and loaded the car to the service truck.. My mechanic say "who knows what the previous owner did to the car"... We could never really understand why it broke Now that I installed LSD torsen differential, we believe loss of grip will be more progressive, as opposed to before where you would get sudden loss/regain grip due to open differential Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted January 10, 2020 Gold FFM Report Share Posted January 10, 2020 CWP failures are often attributed to the backlash not being correctly set. Apparently mine was incorrect on the V8 when i broke mine and it was inspected for rebuild. 1 Quote Only here once Link to comment Share on other sites More sharing options...

MD355 Posted February 19, 2020 Author Report Share Posted February 19, 2020 (edited) UPDATE : 1000 mile / 1600 km service So today I took my car for the scheduled oil & oil filter change after the initial 1000 mile / 1600 km after the break in of the rebuilt engine. Overall I am very impressed with my car. I followed my mechanic's instructions for breaking it in and it has paid off. The car performs amazingly and is very reliable. It starts every time immediately, cold or warm engine. It idles perfectly. No overheating. No misfires. And it pulls hard. I was jokingly saying that my Lotus has become a German car in terms of reliability !!!! (let's not jinx it !! ) 🙂 URGENT HELP NEEDED : I was having oil leaks from the adapters of the oil lines that run to the front of the car and from the RH adapter to the oil cooler. So my mechanic was planning to change just the adapters and keep the oil lines. Today he called me and told me he wants to replace the oil lines running inside the tunnel of the car because they are in bad shape. He already removed the oil line that connects LH to RH oil cooler. Now he wants to replace the 2 long oil lines too. How do you get access to remove those oil lines ??????? Many thanks !!

tmusc Posted February 19, 2020 Report Share Posted February 19, 2020 (edited) You have to take the shifter out, to cut several zip ties that are attached to them inside the tunnel. And be very careful with the fittings at the cooler themselves or you will be in the market for new coolers as well. Just did the job myself. The job itself is not that hard, just a PITA to do.

Mightymetro Posted February 19, 2020 Report Share Posted February 19, 2020 Like above , not difficult but just a bit fiddly. Tie the new lines to the old one and pull it through 1 Quote Link to comment Share on other sites More sharing options...

Popular Post MD355 Posted February 28, 2020 Author Popular Post Report Share Posted February 28, 2020 UPDATE : I just completed the 1500 km service after the rebuild and my car is running perfectly !! This service turned out to be more complicated than the simple oil and filter change. For starters, my car was leaking oil from the oil connectors of the hoses and my mechanic noticed that the front oil line that connects the two radiators was beginning to crack too. So first he replaced the front line and he insisted we replace the 2 main oil lines too. That turned out to more tricky but we managed to remove the interior transmission selector and get it done. Furthermore, the differential was leaking, which my mechanic fixed. And another issue I was experiencing was whitish/blue smoke from the RH exhaust. It turned out the turbo thrusts of the journal bearing were damaged. In the beginning we though it was attributed to metal shavings from when my engine broke. But the Turbo experts said it was oil starvation. This happened when the oil pressure release valve got stuck... They tried to fix the turbo, but it still smoked, so for the price of a repair, the decided to replace completely the internals with new. (See photo of damaged thrust bearing see the lines) Now the car is perfect... It does not smoke... My mechanic said I need to break in the turbo for 300 km. Basically no full throttle high boost... And finally, I jokingly asked my mechanic if he would rather A) get a mild dose of Coronavirus or B) rebuild my Lotus engine... He chose (A) and said he is packing to go to Wuhan China right away !! :-))) Hahaha 4 1 Quote Link to comment Share on other sites More sharing options...
MD355 Posted October 30, 2020 Author Report Share Posted October 30, 2020 Update : Some nice blue flames I've been enjoying the car since the engine rebuild... and the other day my friends asked me to rev the car and see some flames.. I know it is not very good to rev the engine without load, but I did it when the engine was warmed up, and for a little bit... So here are some nice blue flames..

cweeden Posted November 9, 2020 Report Share Posted November 9, 2020 The factory ones are ceramic internals, I would expect all after market offerings to be of metal matrix construction. Take a peek inside and you should be able to see what type you have. Quote Link to comment Share on other sites More sharing options...

MD355 Posted December 26, 2020 Author Report Share Posted December 26, 2020 (edited) It's been a while, since my last update on this thread, and I wanted to let you know that I installed the 350 Sport ECU and the car is performing great !! I actually saw for the first time today 0.75 bar turbo boost in 3rd gear, which I had never seen before.. (I installed turbo boost gauge from 1998 Esprit V8) My question is regarding the Blow Off Valves... When I bought the car, the previous owner had installed 2 Forge BOVs... The modifications I have done to the car are : forged CP Carillo pistons, straight pipes with car delete, K&N air filters and 350 Sport ECU. Do you think I should keep the BOVs.. ? My mechanic believes I might be losing boost pressure from them... Any opinions ? Edited December 26, 2020 by MD355 Quote Link to comment Share on other sites More sharing options...
Giniw Posted December 26, 2020 Report Share Posted December 26, 2020 Hi, As for the potential boost leaks I think it's always a good idea to check whether the intake is air tight anyway, and it's easy to test just by putting regulated compressed air at the turbo compressor wheel. You can use an old bike tube to make a cheap adapter (cut in half, a knot on a side and the other side plugged on the turbo housing at the compressor wheel instead of the intake hose from the filter, and using compressed air. It should be air tight, if it's not then you have a boost leak. You just have to be sure to regulate the air pressure you put in at the maximum permissible boost pressure (like the 0.75 bar you were referring to for instance, I am not sure what it is for a V8 engine) 2 hours ago, MD355 said: with car delete Now that's unfortunate! :D 1 1 Quote Link to comment Share on other sites More sharing options...
mike_sekinger Posted December 26, 2020 Report Share Posted December 26, 2020 As it has been said before, peak boost of 0.75 bar not high and the T25s are really small and responsive. Unless you are somehow addicted to the noise, you can probably remove the BOVs and still observe no detrimental effect on in-gear acceleration. 1 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...
v8GTmac1 Posted December 26, 2020 Report Share Posted December 26, 2020 The .75 bar regulated pressure won’t really work as most of the air built up will escape past any open valves. So you have to just keep going until either your boost gauge reads or you hear something. I like the idea of the bike tube, it’s strong enough! 1 Quote Link to comment Share on other sites More sharing options...
Giniw Posted December 26, 2020 Report Share Posted December 26, 2020 (edited) (I feared the air would escape though any open valves too but it actually doesn't, or maybe the air enters the piston and stays there with the closed exhaust valves. I tested both on the Elan and the 4 cylinder Esprit without bothering about the crank position and it worked for the two cars. Maybe I was just lucky, but that would be strange on several verifications over time -- I checked at least two times on the Elan and once on the Esprit). My guess is that the valves timing don't overlap. Edited December 26, 2020 by Giniw 1 Quote Link to comment Share on other sites More sharing options...
MD355 Posted November 14, 2021 Author Report Share Posted November 14, 2021 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..
