Oil Pan Hit

[monoblanco]

Sup guys, today I hit a parking block with my oil pan. I see no cracks, but it is leaking. Should I just pull it out, replace the gasket and put it back on?

If you're gonna pull it off, put a non-cracked one back on. Duh.

clean outside of pan, find leak, drain pan, JB weld crack handsomely, let dry, refill oil next day.

This^ hairlines can get some JB love.

And nice job parking on a block.

Thanks.
I just assumed that if the pan was cracked I'd be able to see it.
I'll just replace it. Thank u gents.

yea, you may only be able to see it after its removed and has room to flex

Once I take my epoxy fix off, I'm doing this:

I have a bunch of sticks and a blow torch. Metal seal, no need to remove the pan. Just drain the oil overnight.

I busted a hole in my oil pan back in 2006 or so. JB weld did the trick ever since, until I got a new engine last year. Just pull the pan, clean the hell out of it, use a can of brake cleaner on the crack/hole to get ALL residue out of there and slather some JB weld on the outside. Let it cure for 24 hours. Done. Just make sure that you close up any gaps in the metal. Now, if metal is missing, just replace it.

If your going to pull the pan off, just replace it with a used one in good shape. From any non-lowered junk car should be fine.

Thanks BMWman91, but my wrench is analog.

Any word of the setting? I already broke bolt threads in the past. Don't want to do it again.

[bmwman91]

I'd have to check the service manual which I don't have here at work with me.

Honestly, I have always just made sure that all of the threads are 100% clean (a can of brake cleaner usually works nicely), then I put some LocTite on the bolts and then I tighten them to whatever feels right. The threaded holes in the upper pan are sort of prone to stripping, so be careful. That's why I recommend some Permatex Ultra Grey RTV (a THIN coat on both of the CLEAN metal surfaces) so that you won't have drips. The thign to be aware of with RTV is that you never tighten any boolt fully on the first go. Do a first pass where you get all of them finger / hand tight. Then make another pass on all of them to get them snug but not fully torqued. Then, make a final pass to get them to their final torque. I learned the hard way about this years ago when I cracked my thermostat housing by tightening each one fully from the start.

I also recommend starting with the middle bolts and working outward.

perfect!

thanks!
