you should use a little oil before install so your seal won't burn up in the first hour of running

@traviscarr6536 9 ай бұрын

That is a PTFE seal and adding oil will cause premature damage to it. Adding oil may be the case in some applications, especially in years past but this rear seal is meant to go on dry.

Hey slick trick on that pvc. I put those felpro gaskets in but the process we use is much different then the process you showed on oil pan gasket and retaining ring. We put the sealer all the way around the pan. On both sides of the gasket going around bolt holes with about a 1/4 inch bead. Then tighten bolts hand tight. Wait 1 hr and tighten down 19ft lbs on the small bolts and start on the studed corner bolts. They never leak

ugh should had watched your video first, I didn't know about the rear retainer gasket, I just put on the rear seal, can I get it back out carefully to replace this retainer gasket or does it slip around that inner piece to where I can still get to the retainer gasket?

One of the main seal retainer bolts broke on my engine when i torqued them to 18ft lbs...seems, like too much but is it?

@alexlozinski8965 18 күн бұрын

Is there a reason you didn't install the seal directly into the retainer after you took it off the engine, then put them back on as one piece?

@davenkaren2572 3 ай бұрын

I thought, and please correct me if I’m wrong, I’m not an expert, or I wouldn’t be learning about how to do this- but isn’t the purpose of the seal center tool to locate the housing dead center, and you leave the bolts loose until it’s installed, THEN tighten down? I’m asking because I don’t know, but seems logical to not tighten anything until the seal is on and truly centered?

Yeah we love that thing. We actually placed it on the fender lip on the passenger side and then on the PCM. The PCM is dead so that's why we use it lol. We use it again in our latest video kzfaq.info/get/bejne/nZyqgKdhtp7Tk6c.htmlm37s

No it only works with 1987 and up. Below this year's, you'll have a two piece rear mean seal, which is kind of nice because you won't have to drop the transmission

If you are doing this job just drop the trans. Change your u joints on the driveshaft, change transmission mount, and get the right gaskets altogether this should only be 100$ with all of those parts listed

@VeryGoodGarage 4 ай бұрын

I do believe you're correct, doing a quick search I found a few sources that also said 8lbs, 18lbs would be too high www.bfranker.badz28.com/fbody/torquespecs.htm Looking at this under "Crankshaft Rear Oil Seal Housing Nut" suggests 11lbs, I've also seen 10-12 lbs on some other sites, so maybe I'd go with 11lbs if I were to do it right this second

@@VeryGoodGarage i wound up going the full 18, did them all in small sequences up to 18 with the res thread locker, everything seems fine, the 2 nuts that go in the oilpan for sure cant be over 8 because they bolt into the aluminum retainer not the block, the 4 going into the block i think are good at 18 because they go into the block not just into the retainer
