white-gt Posted May 22, 2013 Share Posted May 22, 2013 well guys i had my hybrid rebuilt a good few months ago and its done less than 1k miles but was running sweet untill sunday.. i just left knockhill with the engine all warmed up, i done an overtake boosting at 1 bar to about 75MPH i then slowed as i pulled back in but when i tried to power again their was no boost at all.. i thought a pipe so when we pulled over we checked all pipes but everything was solid! when i tried to accelerate the turbo made a high pitch sound which sounded like boost leak.. we eventually nursed it home and the turbo tone kept changing from a high pitch to nothing and then a low pitch sound which was odd.. when we got home (50 miles) we noticed oil was now dripping from the feed/drain.. their was no squeal on idle so i dont think the turbo was running dry.Whats your thoughts? http://s4.photobucket.com/user/twaiter/media/20130519_193123_zps44f824e2.jpg.html'> Quote Link to post Share on other sites

Starbuck Posted May 22, 2013 Share Posted May 22, 2013 Oil pressure? Have you moved the blades by hand? Do they move freely or hit the sides? Quote Link to post Share on other sites
StuDoc 72 Posted May 22, 2013 Share Posted May 22, 2013 Check exactly where the oil is coming from. As for the whining. Double check you have no boost leaks. Then whip off your air filter and see if the comp wheel is ok like starbuck says make sure it turns freely. Next step is to check the comp wheels itself with a mirror or sumthing to see if any of the blades are chipped if they are this will cause the whining and lack of boost.

white-gt Posted May 22, 2013 Author Share Posted May 22, 2013 i have given the car to IAIN@CRD and he is checking it today.i will let you know if the wheels are moving freely.to me it sounded like the shaft bearing was done it and when we arrived back their was a sort of metallic sound which sounded like the blades touching the housing. i just wondered if any one had any other ideas? if it was a boost leak the oil wouldnt be leaking. the rest of the engine seems fine..

StuDoc 72 Posted May 22, 2013 Share Posted May 22, 2013 Aw does he have it thats sound then i'm sure he will diagnose it. To me it sounds more and more like the bearings have collapsed although if they had I would expect it would be smokey as hell rather than having oil running from it. Hybrids arent cheap though pal so if you want it repaired or replaced you will be forking out.. Is it TD04 im assuming from what looks like a downward facing hot pipe? Where in scotland you from?

white-gt Posted May 22, 2013 Author Share Posted May 22, 2013 no pal its just a CT9 hybrid rebuilt by Jezzas cousin.. it was running great so i dont see what the problem is.. im in EK dude, often in town etc, black ep82 with toms kit etc. i cant afford to forge which is why i wont run a td04.. theirs no smoke from the car at all, it was very strange! boosted past people fine then suddenly nothing. not a sausage.their was no oil at the time, no smoke no nothing. io think its the bearing or something as well tbh, it sounded like the wheels just would turn easily.

StuDoc 72 Posted May 22, 2013 Share Posted May 22, 2013 Just looks strange in that pic looks like the hot pipe is facing downward with a pop on hot pipe rather than bolt on. Ah I see Jezza's a good guy. Do you know what was done when he rebuilt it? If it wasnt balanced that would almost definately mean the problem is that the bearing has collapsed. EK I actually got my new car from down there. Quote Link to post Share on other sites
AdamB Posted May 22, 2013 Share Posted May 22, 2013 You running an aftermarket stainless manifold? Quote Link to post Share on other sites
white-gt Posted May 22, 2013 Author Share Posted May 22, 2013 their is a list of what was done and balancing was certainly done. its a SS mani which has been welded (off the car). im not sure what you are talking about with the pipes? is how it is setup wrong? i bought mine from Manchester, it was a shed! ive gradually got her good!

StuDoc 72 Posted May 22, 2013 Share Posted May 22, 2013 Im assuming the mani hasnt cracked again? Just the way the pic looks mate nothing is wrong. Quote Link to post Share on other sites
WallaceGlanza Posted May 22, 2013 Share Posted May 22, 2013 Sounds like the oil leak is from the feed to the turbo and its been starved of oil, I had this when the feed got blocked and had similar symptoms until the turbo properly shat itself in a mass of smoke! Turbo will likely need a rebuild... Quote Link to post Share on other sites

Turbo will likely need a rebuild...This sounds spot on to me! Feel free to let my place look at the turbo if you're struggling I work at midland turbo! Quote Link to post Share on other sites
TurboTobz Posted May 22, 2013 Share Posted May 22, 2013 Oil feeds are crap especially with a aftermarket manifold, really hard to pinpoint the leak aswell. Quote Link to post Share on other sites
white-gt Posted May 23, 2013 Author Share Posted May 23, 2013 Well Iain has came back saying the hybrid is fine. No play in and out and very little side to side with no damage to the blades or anything.. Is their an after market fees pipe? I think Iain is gonna put it back on and see how it goes.. No idea what the problem was.. Quote Link to post Share on other sites
daniel_g Posted May 23, 2013 Share Posted May 23, 2013 You can get braided oil feeds from zisco, race-tech etc. Quote Link to post Share on other sites
TurboTobz Posted May 23, 2013 Share Posted May 23, 2013 Racetech were doing a group buy last time I saw real cheap too Quote Link to post Share on other sites
white-gt Posted May 25, 2013 Author Share Posted May 25, 2013 Turns out the hybrid is screwed internally.The standard unit boosts great but the hybrid does host some but not as powerful as the standard and their is a loud wine. Quote Link to post Share on other sites
Liam_D Posted May 25, 2013 Share Posted May 25, 2013 Least you know what the problem is! What hybrid is it? Whip the turbine housing off and have a look at the exhaust side blades see if there's any damage to the blades that could be causing the power loss and whine. Quote Link to post Share on other sites
white-gt Posted May 25, 2013 Author Share Posted May 25, 2013 I will do mate. The standard is back on now Quote Link to post Share on other sites
