Comp turbo leaking coolant from zerk fitting

Jinxx · 04-12-2019, 06:14 PM

So I noticed coolant leaking from my turbo ...got under it to track it down ....leaking from zerk ......called comp turbo and the told me the zero is threaded in .the zerk itself threads in to the sleeve and the sleeve is threaded in the turbo with a O-ring ....having no luck getting the sleeve out ...has anyone been through this and have any info ..other than pliers and hope for the best?

The zerk fitting has a hex nut at the end. If it is unthreaded it should be easy to pull out...I think COMP would have the exact instructions.

Yes the zerk threads out easy but the sleeve that the zerk threads into is what I can’t get out .....Comp turbo says it is threaded as well with a O-ring and to use pliers to carefully unthread it ..but I’m not having much luck

You may need to buy or fabricate a tool. I've seen people use a pair of vise-grips with bent jaws to get into tight places. A stud extractor may work.

Yea I have some needle nose vise grips and some extractors Im about to try ...Comp says to leave the zerk threaded in when using the vise grips so it doesn’t crush or make the sleeve oval .....I’ll see how it goes in about 10 mins

Well if it’s threadded in I can’t get it out ... looks like I’ll have to remove the turbo and ship it back to them

Try to find a bolt with a nut to put in and tighten the nut then you can put a wrench on it

It’s threaded on the inside ..smooth outside .....need something to grab outside of it

lj909 · 04-13-2019, 11:48 AM

I know, put the bolt inside, spin the nut down and tighten it. Then wrench it

Jinxx · 04-13-2019, 11:53 AM

Ok ... so I got it out ... and from what Comp turbo told me was that there was a O-ring ... what I pulled out looks more like it was wrapped with Teflon tape and no sign of a O-ring

Jinxx · 04-13-2019, 09:36 PM

Replaced the o-ring locked everything down ...seems to be good now I’ll see how long it last

Jinxx · 04-20-2019, 10:21 AM

Well ...got about a week and the o-ring blew out again on the turbo ...back to square one. Maybe the o-ring wasn’t high enough temp range and it melted

Replaced o-ring with a viton o-ring which is what is used from comp turbo ...hoping this takes care of it

No bueno. Thanks for keeping us updated. Did the turbo have a weird whine before the oring blew out?
