Oil leaking out of the turbo

**RandyRhydah** · 26-09-2010 06:57 AM

ever since putting the turbo in i have had a mystery oil leak around the turbo area. ive rewelded the drain bung and checked the feed line and its not them so i assume its the seals in the turbo.

the oil only leaks when the car is turned off but when its tuned on it wont leak a drop

any advise would be great

cheers

Degrease the WHOLE area, so its is TOTALLY clean from any dirt/existing oil. Go for a drive or whatever you need to to. Go back and check/trace for leak.

just to add some more information i just found out the oil feed kit i bought doesnt have a restrictor. so ive ordered one of them. and i have oil in my cooler piping but im running vent to atmosphere at the moment so is this indicating that good chance the turbo is shot?

Your turbo might be ok. What turbo? If your turbo has not got a in built restrictor, you could have solved your problem.

I had the exact same problem.

You need a 1mm restrictor even an 1.2mm was not small enough and kept leaking

That's what I'm running on my GT2871R

Once I installed it stppped leaking and yeah your turbo with be fine

You need to remember Honda motors push up 80+ in oil pressure unlike most normally boosted low comp motors that only push 40ish psi

Depends on size of oil feed line too. Used -3 line, no restrictor, except for in built one in the GT turbo. No issues.

turbo is gt2530 on a b18c

feed line is 4an and ordered a 0.8 restrictor.. will update once installed whether it still leaks or not.

cheers guys

ps luke gt2871 a good size for the b18c? my car feels like it dies in the ass up top end.. not sure if the turbos to small or if its because it is running stupid rich and untuned... if after the tune i realise its to small im thinking of the 2871

gt2530 is way to small mate

GT28 would be the smallest I would ever go

my research says the gt2530 is a hks turbo and is exactly the same as a gt28rs.. i dont know much about turbos but thats just what ive come up with on google / ebay

Yeah the gt28rs (disco) is too small IMO
