WT2002CARS Posted September 5, 2016 Report Share Posted September 5, 2016 Hey everyone, Suicidal Lotus Esprit V8 twin turbo owner here. I have had engine rebuilt with new heads and I'm convinced this V8 has been chipped as literally at 140mph from 4th to 5th gear with accelerator down you can spin the rear wheels. However the head gasket keeps blowing. Yep fourth time now so completely numb now. Can anyone help me or offer advice as to get it detuned ? I love this car and it's going to be the death of me. Every time the coolant blows into exhaust via head gasket. Look forward to any help. Regards Wayne Quote Link to comment Share on other sites More sharing options...
ramjet Posted September 5, 2016 Report Share Posted September 5, 2016 I presume that if the heads are new that the block has also been checked for flatness? I can't help with any info to get it detuned, but I am sure that some of the other V8 owners will be along to help out. Four times. I can understand you being annoyed.

silverfrost Posted September 6, 2016 Report Share Posted September 6, 2016 As Michael has said above you need to check the flatness. Is it always the same cylinder head that keeps blowing.? But yes defo check the flatness of the block and also the cylinder head, chances are it has warped and you/the workshop have been just cleaning and refitting it which will sometimes hold for a short while on the new gasket but eventually blow through. I would also be looking into what boost you are running the car at, not really a turbo man myself so others will shed more light. Four times i can see why you are going crazy, must of cost you a fortune, more so that your engine has survived the cambelt been replaced four times, most people do not like fitting these once every blue moon let alone four times.... I hope this gets sorted soon for your sake and the cars. Quote A Link to comment Share on other sites More sharing options...
mike_sekinger Posted September 6, 2016 Report Share Posted September 6, 2016 To echo the other comments, check the mechanical topics - flatness, correct parts, torque settings etc. But it sounds to me that you have incorrect or even no boost control - I would check to make sure that your wastegates are installed with the correct springs and that the base mechanical boost is set correctly. Check that your wastegates are actually moving and are not seized. I doubt that your ECU is the main source of your problem, but you could swap out for one with a standard calibration to confirm that. I'm assuming that you do not have an aftermarket boost controller? If you are constantly running with overboost, I would expect the head gaskets struggle time and time again.

WT2002CARS Posted September 6, 2016 Author Report Share Posted September 6, 2016 Thanks for all your advice Guy's and will share with you the outcome as I replaced heads last time as well. So I'm scratching my head. Cheers Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted September 6, 2016 Gold FFM Report Share Posted September 6, 2016 Fingers crossed for you chap. Mikes spot on as ever - you need to make sure it isn't overboosting. The capsules and wastegate are easy to test look forward to a nice positive post where she's back running again Quote Only here once Link to comment Share on other sites More sharing options...

gmendoza Posted September 9, 2016 Report Share Posted September 9, 2016 Who built the car? Any idea what's been installed? Even if your car was running perfect, shifting hard enough to make the tires break loose at 140mph is just begging for trans issues. 2nd, MLS headgaskets need a perfect surface to seal correctly. The surface needs to be like glass basically. If you can see machining marks, like a vinyl record, it'll leak. 3rd, rumor has it that the Esprit has a tendency to lift heads at very high boost with stock head bolts. Were ARP studs installed? 4th, how do you know its a head gasket issue? Overheating after WOT run? Water mixing with oil? Like others have said, I'd check your boost first and get that under control.

silverfrost Posted September 10, 2016 Report Share Posted September 10, 2016 I am with Barry on this one, To disclose what someone else has written in good nature in a private email is pretty rude in my mind. But on the other hand you could of written what ever as its not a direct post so how do people know if you have not changed some of the wording. Either way still pretty rude imo 1 Quote A Link to comment Share on other sites More sharing options...
Guest Posted September 10, 2016 Report Share Posted September 10, 2016 (edited) Not rude at all, its public information not a secret disclosure, i dont want knowone to go thru the nightmae ive been thru, people wants experts to chime in on this subject other then just owners. And if my horror story is saving a human being from a complete nightmare day and nite for year after year then cheers. After all the money me and my family have spent on 1 car please i have the right to do alot of things not only is it rude to try to cover up someone prefessional expertise to not tell people. Thats whats rude, . I dont got nothing to hide and knowone has handed me a dam thing in compensation so do you really think i g.a.f.like i said luckily i love my car or else i woulda went and bought another highly desirable car to add to the collection and left everyone sad that a beautiful restored esprit v8 isnt flying aroundmaking peoples jaws drop. Think of both ur comments and then maybe ask yourself 1 thing are you a sheep or are u a wolf????

silverfrost Posted September 10, 2016 Report Share Posted September 10, 2016 K calm down, you need to think before you post, Coming accross as aggressive in posts and then editing them afterwards inserting less aggressive words is not very grown up. Regarding words like sheep or wolf, I have no idea what you are talking about. You come accross as a sort of strange internet troll type with some of your wordings, you remind me of a certain member called Teigan from many years ago who just had an amazing way of rubbing people up the wrong way. First time i have posted on this forum about someone elses posts in 11 years. Chill out and try not to take everything to heart. 1 Quote A Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted September 10, 2016 Gold FFM Report Share Posted September 10, 2016 I'd simply like the facts. we have two different gaskets - it could be gaskets, head flatness, block flatness - a combination of all of those - one gasket might cope with imperfections better than another ?? I don't know - but it needs putting to bed. Quote Only here once Link to comment Share on other sites More sharing options...

Gold FFM Barrykearley Posted September 10, 2016 Gold FFM Report Share Posted September 10, 2016 Thanks @Bibs i think it's important that this issue is explicitly clear. It's more than likely different gaskets need a different process. It's very important given the cost that we know what the issues are. im just very happy I didn't pull the heads off mine 1 Quote Only here once Link to comment Share on other sites More sharing options...
Vanya Posted September 11, 2016 Report Share Posted September 11, 2016 Really sounds like it's a lack of boost control - especially regarding the wheelspin at high gears. With new tires in the dry I don't get any wheelspin in my V8 - maybe 1st or 2nd if I pushed them, but I don't thrash those gears so much. Definitely no spinning in 3rd and up. And last I checked my boost was behaving right. Quote Vanya Stanisavljevic '91 Esprit SE | '97 XK8 Link to comment Share on other sites More sharing options...

I'm surprised at that as on a good dry road when the turbo started boosting my S4s would spin the wheels in third, although I had fitted the PUKE High Torque chip.

Vanya Posted September 12, 2016 Report Share Posted September 12, 2016 I'd buy that on a 4 cylinder Esprit since the power comes on suddenly. The v8 is quite linear all the way through the power range, pulling more in higher revs. Quote Vanya Stanisavljevic '91 Esprit SE | '97 XK8 Link to comment Share on other sites More sharing options...
