Title: Oil drain tube
Post by: Shimy87 on August 10 2022, 05:49:43 PM
This thing has always leaked a bit so got ambitious and decided to put a new gasket in it. Leaks worse now! Going to remove whole thing and see if its cracked....... oil shows up on top of gasket that sticks out a little so don't think its cracked. Maybe its warped a little???  Pain in the ass to get to!!

Turbo drain line?  They often crack and a factory style tube is much better than the steel braided hose aftermarket junk.

Be sure the fitting going into the block is tight.

File it down if it's not flat.

My Throttle Body was leaking a bit and when I checked it it looked like it was slightly wrapped so I place emerald sand paper on top of a piece of glass and the Throttle Body surface came out smooth and level.

Well disconnected from turbo and checked with a straight edge and seemed good, made a new gasket and used some orange hi temp silicone on each side. Put back together, didn't tighten up real tight, let it cure overnight and final tightened it today. Cleaned everything real good with degreaser and water spray.......st ill has a small drip hanging off the lower bolt head. No cracks in pipe.. Looks like I'm going to have to do the sandpaper method to ensure flatness. I can't believe with a gasket and silicone this thing still leaks!!!

I have better luck without silicone.  If I use anything it would be the NASTY permatex aviation
