Well, the leak ended up being the o-ring on the adaptor, new o-rings on the line-to-adaptor didnt do the trick. The replacement adaptor to block o-ring was thicker then the one i had originally put on. I didnt bother with any rtv, its hell enough trying to work in that tight space. I did use a tourque wrench this time, and so far-so good!

 

That's the same problem I had when I did that job. My solution was to peel the plastic off the top and bottom of the adapter-to-block gasket. After that the adapter would snug up to the bottom of the block well enough that the o-ring would seal up OK. I *REALLY* wish someone would have told me about that before I did the job the first time. It could have saved a lot of time and trouble.

 

Same here!!!! The one at the parts stores is too thick! The only thing worse than doing this job is having to do it twice (or more...)

 

I do not do any towing or anything of that nature, strictly city truck, so do not take what I say seriously. But I completely deleted the remote housing and put the filter back on the block. Took a 400+ mile trip without a problem. GM has a wonder developing this on their hands...
