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.
righto will give it a go and get back to you guys
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.Quote:

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 mateQuote:

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 IMOQuote:

I'd go bigger if you want good safe power GT30Quote:

The gt2871 will still work well on your B18 though
put the resistor in today... still leaking oil thought
its coming from around the sump and a little bit higher and it only leaks when the car is turned off. if its idling it wont spill a drop
its not the sump gasket because i replaced that when i first noticed the leak... the shop that welded my bung in used silver solder so maybe with the rapid heating and cooling it could of warped my sump?
just throwing out random ideas now
-8 or -10 oil return lines?Quote:

not 100% had -8 but replaced it with one a little bigger so i assume -10? its free flowing and isnt kinked or bent too much... what do you mean it took you 5 tries was the gasket not seating properly or bung not welded properly?
Kept leaking through the gasket time and time again.. finally got her seals..Quote:

hmmmm i wonder if thats worth a shot with me aswell... hate taking the sump off lol
what liquid gasket do you reccomend?
Tell me about it!!!!!!!! I need to remove the turbo/manifold/dump pipe/AC fans and some of the exhaurst to drop my sump :(Quote:

oh sht lol i dont have to take the manifold and turbo off to get mine out.. i feel better now
thanks for the info sorry to be such a pain ill give it a go tomorrow arvo and fingers crossed it is my sump...
replaced the gasket for the oil drain fitting on the turbo because it was moist... also went nuts with the toyota black sealant stuff around the bung on the sump and the leak slowed down alot.. will have to get it rewelded and hope for the best
I've got bolts welded to the inside of the sump so I can tighten the flange via screws if needed. plus then I can remove or change the flange should I need tooQuote:

i was told this by Mike Vine at Mike Vine Turbos, i purchased a kit and its built up back into the turbo it had sat around and
siezed.... i managed to fix this though...
ill have a look i did put the drain bung as high as possible on the sump im pretty sure it is in a good area... its leaking alot less oil then what it was, im on the dyno tomorrow so i might go nuts with my sealer just to fix most of it before i go then but i definitely need to get it fixed before next Wednesday when i go to willowbank because i dont want to be "that guy in the civic who dropped all the oil on the track" lol
Yeah that would be very embarrassing :)Quote:

http://img1.tvloop.com/img/showpics/...00_1_30012.jpg
no oil under the car this morning for the first time in 2 or so months.... it must be the drain bung even though ive got the shop to weld it twice now... might get my mechanic to do it this time
thanks for the help guys dyno at lunch time today... will throw results in my thread in the appearance gallery
Nice one bra!!Quote:

What's ya setup anyway?
B18.... turbo?

hoping for over 200hp on 10 psi dont care much for drag racing a 12 would be nice but expecting mid low 13s because im not the best driver
would love to get in the street sprints series for next season hopefully hitting the qr sprints on the 30th
heres the thread

YOu'll need more than 200HP to get close to 12's lolQuote:

My guess would be 13.6 with 200HP
im a big turbo noob so i have no idea what to expect made 160 na
yeah 160HP = 120kw what's about right for a good nick tuned B18C7.Quote:
