Anthony Posted April 25 Share Posted April 25 (edited) I generally follow whatever recommendations I see from GM, but this time it failed spectacularly. A service bulletin from the '90s said to upgrade the oil pan gasket to their new design from AC Delco which is supposed to be so good that you can even reuse it. The first thing I noticed was that it didn't fit very well. It was floppy, hung over the edge in places, and getting it to stay in place while installing it was like trying to make a fish sandwich while it's still alive. The instructions that come with it and in the bulletin say to torque the bolts to 10, then 16. This seemed to squeeze the gasket out, and deformed my new pan. It started leaking and progressively got worse, so I ordered a new gasket. This time I ordered the Fel-Pro PermaDry Plus. This gasket is a solid piece that doesn't flop around or squeeze out. It comes with 4 handy helpers called SnapUps that you screw into 4 bolt holes, and they hold the gasket and the pan in place in exactly the right spot, freeing up your hands to put the bolts in easily. Once you get a few bolts in, the SnapUps just unscrew and you can put the last 4 bolts in. Incidentally, I tried doing a search for "oil pan" on this site, so as to avoid make a duplicate thread, but the search doesn't seem to be working. It returned zero results, even though there is another thread on that very page about oil pan bolts. Edited April 25 by Anthony 1 1 1 Link to comment Share on other sites More sharing options...
sarookha Posted April 27 Share Posted April 27 I usually use Google to search this forum (and others), by adding ::reattaowners.com (or whatever site you want to search) after my query. That forces Google to prioritize hits from the site you are interested in. e.g. Oil pan gasket ::reattaowners.com brings up two threads 2 Link to comment Share on other sites More sharing options...
Anthony Posted June 24 Topic Author Share Posted June 24 Update: I got a message that said the oil level was low. Dipstick was dry (the one in front of the engine, NOT the one behind the wheel 🤪). It turns out that the small bolt at the front of the oil pan (leftmost when looking toward the front of the car) actually has a hole that goes all the way through to the inside of the engine's front cover. Being the fastidious person that I am (putting it nicely), I had cleaned all the gunk off that bolt before putting it back in. That made a nice path for oil to travel down until it escaped entirely. Being summertime, I thought that growing pool under the car was just A/C condensation 🤦♂️. In a bit of an oversight, the service manual and subsequent bulletins from GM forgot to mention that you need to put some kind of sealer on that pan bolt. I added some Permatex Ultra Black gasket maker to the threads under the head and put it back in. We'll see if that holds. 🤞 Link to comment Share on other sites More sharing options...
