Oil Pan Leak!! HELP!!

**L3THAL_Z28** · 09-09-2007, 07:16 AM

Ok so last night coming home i hear this thump under my car when im on the freeway...i guess something hit my car from under and cracked my oil pan

...the crack is at the bottom part of the oil pan and its small (you wouldn't be able to tell if you didnt see the oil seeping out)

Well the oil was seeping out fairly quick so I drained it and bought a sealant (since the crack is tiny)...After I clean the area and apply the sealant and let it dry what do i do next? I think i read somewhere around here to put tape and then some more sealant after the first application...is that right?? can someone please explain?? i want to do this right. Pictures would be great also.Thanks.

What kind of sealant did you use?

**L3THAL_Z28** · 09-09-2007, 09:51 AM

SealAll contact adhesive and sealant...got it at autozone..it says its gas and oil resistant...plus in the back it says its good for "repairing and maintaining oil pans and oil lines etc."

As long as you covered the crack good enough, one more time might not hurt, or try putting in some oil and see what happens

Oil pan is about $200.....gasket is about $30 to $40 & don't you have to pull the engine to replace an oil pan on an LS1??

Doesn't sound like a cheap venture so far even without pulling the engine.

I would agree with Sarge, Since the Oil pan is part of the structural integrity and rigidness of the motor i would replace the oil pan. No you dont have to pull the motor to change the pan.

I want him to replace the oil pan that is super glued with a new one and replace the old gasket with a new one at the same time. I see guys replace the oil pan and leave the old gasket on there and of course here come the leaks......so I always tell the kids...replace the pan and the gasket.

Should be fine as long as you cleaned up the pan first for awhile, anyway.

This isn't a permanent solution either. First time that hunk-o-gunk falls off your oil pan due to heat, vibration, road debris, whatever, youre not going to know it for awhile, and you DONT want to run these engines low on oil.

Its a temp fix until you get the cash together and get a pan and gasket to replace it, and something I would keep a close eye on.

They do make "guard" type things you can attach to the bottom of your new pan if this is a problem in the area you drive in.

Since the engine doesn't have to come out, I would get a new gasket & take the pan to a welding shop & have them heliarc it.
I see no reason to trash a good pan for a small crack. But that epoxy has got to go!

ok so i filled her up with oil this morning and drove it to school...the sealant seems to be holding but i don't want to worry about it so i'll be replacing it as soon as i can get the money for it...besides now that i've been under there there seems to be another small leak.

Car is about to hit 100K miles so i guess its a good idea to just replace the seal and the oil pan. What would best...get a new one or weld the cracked one like rbob93 suggests?? Like i mentioned the crack is barely even noticeable.

yeah stupid me, i didn't read it slow enough.

I had my oil pan gasket replaced on my 2001 Z28 three months ago. The dealer told me they had to lift the engine from the motor mounts to remove the pan. They charged me $400. Did I get hosed?

Take it and get it tig welded and it will be fine. Unless money permits a new pan. You can look at a couple bearings while you have that thing off to, Which will tell you weather or not prior owners kept up on the oil changes.
