GM switched to an aluminum castings in the newer cars. That should probably tell us a lot.

True, but of the people on here that have replaced their plastic/composite UIMs already, how many have had multiple repeat failures in so few miles?

Update for the non-GH folks.... I'm going to tear it down next weekend. Yes, I'm very frustrated as to why this keeps happening, but at the same time I'm intrigued.

At this point (without tearing into the latest failure), the common theme is the Felpro UIM gasket. It'* what caused me to do the last swap, and from what I can tell thus far, what'* prompting me to do this swap.

For now, I'm going to pass on the Bars-Leak. I've always been very nervous about using additives/"mechanic-in-a-bottle". Nothing against the suggestions, but I'm going get right into it to find out the mechanical failure.

Understandable, I'm trying to get a L67 in place of the L36

But seriously, I'm also intriguted too. maybe you reassembled it wrong? Not that you would but it could be a possiblity

It is a possibility that I reassembled it wrong. I've made one mistake before.

Seriously, though, I'm really thinking the Felpro UIM gasket is to blame....

Yeah, now would be good. Auztozone or the like. Bar'* Leak or another brand aluminum powdered stuff.

I did that, I used Bar Leak to see if it would stop the small coolant leak and it did.

Refresh my memory-did I sell you a sleeved upper? I rmember a Columbus suburb address.

No you never sold me anything, I just tried Bar'* Leak to see if it would slow down the leak (if there was one) and it worked, the level hasn't dropped any, and that was about 500-600 miles ago.

then I suspect a throttle body gasket or heater core leak rather than a UIM.

are you serious? I brought aluminum LIM gaskets. I'll PM you so the topic doesn't derail.
