ive replaced 3C0129646 green oring 2 times on the turbo inlet and its still leaking is there any better oring i could use? any input would be great
yea i did a boost leak test and it leaks bad...
A boost leak test would just demonstrate that the turbo inlet coupling isn't airtight (at the minimum), which is part of the problem. Why that seal is so poor, the world may never know. Bottom line is that it's unacceptable. I can understand some sweating/weeping, but it just gets all over the place down there.While I agree that is a common issue, that is pre-turbo, so it isn't a boost leak. The leak comes from normal crankcase vapors being drawn into the air inlet.
Usually it isn't enough to worry about, but in some cases it can seep enough to ruin the heater hose.
The potential for unmetered air entering the turbo is so small as to be insignificant IMO with regards to running condition/performance; but that doesn't excuse the poor design.it is pre turbo but after maf... so wouldnt that affect things..or am i wrong..
Looky here for verification OP is correctThat's the outlet isn't it? You don't get that ring on the intake? Not the centre hole but the lower one, the pipe comes off and heads to the IC? I reckon the metal of the actual pipe end has worn down to much so a new seal just wont do it any more.
I purchased this size after reading your post but couldn't get the elbow onto the turbo, no matter how hard I tried. I lubed the o-ring and turbo itself, nothing. I'm no bodybuilder but not weak either. Any tips?The size I'm using is 4x45mm. I'll have to look in ETKA again to see what the stock size is.
That's what I like to hear! If they're still dry this seems like a permanent workaround, which I am all about. I guess I'll have to drink a red bull or my pre-workout drink before I attempt this again. Thanks for the input brother!They are very hard to get on. You have to sort of twist and roll it up onto the inlet. I used to lube with grease but now I just drizzle some motor oil on the o-ring and inlet.
It hurts my hands. I'm not a big strong guy either.
Have had multiple cars with this o-ring installed come back through the shop for other things and all are nice and dry at the inlet. I think it is worthwhile. Probably there is a size somewhere in between that will be easier to install but equally effective. I really just grabbed the size out of thin air.
