M4RK RZ Posted April 2, 2007 Share Posted April 2, 2007 Thanks Alex, but I'd prefer it if you didn't respond to any of my posts in future with an attitude like that. Dont worry mate I got the same silly responce from Ric "Enthusiastic Rolling road, ive tried to explain it too him many a time " Very helphul indeed not. Anyone have any real views after I post up my dyno tonight - more than welcome Lets take into account I have no idea if the internals are standard or not when I bought it + I dont have xray eyes (yet). But the turbo blades are not normal jap spec if that helps lol Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 2, 2007 Share Posted April 2, 2007 If you want me to look at it agian, the offer still stands. I seriously doubt just a half inch over on the dipstick will cause the smoking. I ALWAYS put 10 / 12 mm or so over in my TT when doing track days, to help counter oil surge, and it never smoked. IMO the only reason the front oil seals blow out is due to a *uggered engine with a load of crankcase pressure due to poor piston ring control causing blow by. Time will tell, but i wouldn't expect draining a tad of oil will fix this, it's going to be either turbos or stem seals, just MAYBE piston rings.

Anyone have any real views after I post up my dyno tonight - more than welcome He only said what's true...1bar and 400HP isn't possible on j-spec turbos no matter which dyno you used. And Greg, Dyno or no dyno it doesn't matter...there are a number of variables that change boost pressures...the main one being the weather...but far be it from me to point out the obvious to you.

Chris wouldn't a compression test establish if the engine is *uggered. I had a lot of problems with the front oil seal blowing on my car (3 times in as many months) after about six months of ownership. The cause as you say was a worn engine, causing pressure in the crank case. Quote Link to comment Share on other sites More sharing options...
M4RK RZ Posted April 2, 2007 Share Posted April 2, 2007 400HP isn't possible on j-spec turbos no matter which dyno you used. Can you not read? "Lets take into account I have no idea if the internals are standard or not when I bought it + I dont have xray eyes (yet).

Pete Posted April 2, 2007 Share Posted April 2, 2007 Rest assured, I won't be on the forum for much longer and I certainly intend on getting rid asap, maybe before the Dragonball too as I've seriously had enough. Oh no! It's not long now, hang in there! Quote Link to comment Share on other sites More sharing options...

Expect the worst again I shall then. As I said, the engine should be good. GBH only fitted it 2 years ago with 37k km on the clock. Turbo's are under warranty from Envy so that's not a problem as Gaz has agreed to replace the seals if needed. Valve Stem Seals seems to be a certain possibility. Hoping it's not the Pistons - which I take it will be the most expensive of all three problems? Quote Link to comment Share on other sites More sharing options...
Mike B Posted April 2, 2007 Share Posted April 2, 2007 greg, have you checked the rest of your exhaust just to see if there is a potato jammed in there too? 5.5k on a bpu, sir you deserve a break... karma will come around and hopefully you'll win the lottery by the end of the year and not be bothering with us on pikey.net; you'll be with chris on lambo.net Quote Link to comment Share on other sites More sharing options...

Well, just started her up and idled over and no signs of smoke at all so I don't think it's the Valve Stem Seals as Chris mentioned they release a powerful puff of blue smoke after leaking overnight. I'm going to see how she runs tomorrow on a brief light run. I'm not getting my hopes up about anything. Just to clarify, I had a chat with Chris earlier and he understands my position. I am in no way having a go at Chris or faulting his excellent work. It's just one of those issues that is shrouded by another, and another and another etc! Turbofit have also agreed to have another look at the car to make sure all is OK at no additional charge, as of course has Chris. Thank you both. I know I got a bastard of a car, I never thought about looking on this forum either. I was niave and damn stupid to go along with a bundle of cash without any prior thought process. I know that now. I've learnt my lesson and after this car, never again. No Supra that's for sure! Greg Quote Link to comment Share on other sites More sharing options...

Sheefa Posted April 2, 2007 Author Share Posted April 2, 2007 Indeed Pete, well perhaps! Just to advise, Greg @ Turbofit did a complete compression test on my engine before work commence and all cylinder compression results came back perfect. Around 15psi or something each, so I'm happy it's not the piston rings or pistons. No black oil on the spark plugs either. Some good news I suppose. Looks to be the VSVs then!

michael Posted April 2, 2007 Share Posted April 2, 2007 Did he do a leakdown? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted April 2, 2007 Author Share Posted April 2, 2007 Not sure Michael mate. He just said the engine is absolutely fine and no probs at all. He assured me the turbo seals were fine too and if they happened to go and needed replacing, he'd pay to get them done. Quote Link to comment Share on other sites More sharing options...

Just to keep things in perspective here the reading was between 150 and 152 psi across all six. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted April 2, 2007 Author Share Posted April 2, 2007 Thanks Greg. What's a leakdown test anyway? Is this to identify bost issues? Quote Link to comment Share on other sites More sharing options...
Bob Posted April 2, 2007 Share Posted April 2, 2007 Greg, a leak-down test is basically pressurising one cylinder at a time and listening for wherever air leaks from, e.g. exhaust, inlet, etc. Quote Link to comment Share on other sites More sharing options...

Sheefa Posted April 3, 2007 Author Share Posted April 3, 2007 Thanks Bob. Chris, little worried there! Is this one of those 'my friend has this problem.....etc' stories when really you're referring to yourself "getting jiggy with it" with Jane behind the Restaurant? Would love to come, but time, money, car not working, girlfriend having a moan are all non-negotiable factors at the moment. Quote Link to comment Share on other sites More sharing options...
