OIL PAN Gasket Replacement Tips

[davem]

just did this last weekend, so for future reference...



there are 4 torx bolts that attach the inspection place to the trans. An 8mm wrench will work if you don't have a female torx socket.

I used just a dab of permatex gasket sealer (pink stuff) where the front and rear engine covers meet the block. Also make sure to torque the pan bolts from the center outwards to ensure a nice even seal between the pan and the block.

I also highly recommend getting the Pelican Parts oil pan gasket kit. it not only comes with a new gasket but it also has all new bolts which makes for a cleaner, easier install. I was thrilled when I opened the package and saw those shiney bolts... I was dreading cleaning up all 20 of the old ones.

link to kit?

anyone have any trouble removing the bell housing case even after the 4 bolts holding it were removed...what gives? all bolts to pan and bell housing are out...

I agree with the above.

I can't stand cork gaskets and I really can't stand RTV either. I have seen more oil leaks caused by rtv then not. In most case's rtv sealer is not applied correctly and this will almost always cause a leak sooner then if the gasket was simply applied correctly with no sealer.

I personally use a non-hardening liquid aviation gasket sealer/adhesive. I typically only use it on one side to secure the gasket to the mating surface.

RTV :down:

This information is backed by 20+yrs of general automotive repair experience.

Certainly agree.

I'm about to do this soon. I have the gasket....do I need any type of sealant and do I need to put it over the entire gasket or just the corners?

This is what you need to cover both sides of gasket, block, and pan with. Let tack for 5 mins, install, and enjoy a clean driveway!

a very small, very thin layer over the corners. If you use to much the gasket will push out and you will have another leak.

I ended up using straight RTV (loctite 5699 grey), no gasket. After building a couple SR20's, JDM mfg's kinda know how to build motors that don't leak.

I used toyota FIPG!

For just about any gasket I've found Elring Curil K2 to be the best for most applications like this.

Its non harding so it can shift and form over time for continuous sealing AND it smells like Krispy Kream donut glaze.. but don't eat it.

I believe BMA carrys it at around $14 a 75ml tube.

Itll probably take 2 hours on a lift...I had to do it on my back once. Took half a day from jack up to jack down.

sweet im glad i have access to a lift then lol. probably have to do this on saturday.

[firemanory]

Thanks a bunch. That is what I needed. I will be doing on jackstands if I am to tackle this. Will see what I decide to do.

How long has it taken you guys to do the job from start to finish...

John, go to the dealership and ask them. I'm sure Pelican Parts will know too.

The OEM cork gaskets leak eventually because they harden and the asymmetric expansion and contraction of the pan and block plus the vibration pulverizes them after a while...

The composite (cardboard like) ones only leak if installed with too much goop on them because of that same scrubbing action between the block and pan, the goop comes unstuck.

This tech information (SOP) is backed by 27 years of BMW oil pan gasket leaks (I've probably done like 300+(???) in that time) and I know what (and how long it took) to come back leaking again.

have a part number for the good gasket? composite (cardboard like)
