i have a tiny crack in my oil pan and i wanted to know what the gurus of teh L61 would offer as a quick fix.

does anyone here think that JB Weld would do the trick in just plugging that tiny crack up?

i've checked my oil every few days since i noticed it was leaking and it seems like nothing is leaking very badly. oil always says its where it should be, but i want to know if i could repair it next time i do my oil change.

i would just drain the oil and drop the pan. clean it with some degreaser and then denatured alcohol to make sure it was clean and then throw some JB Weld where it looks like the crack is.

the real question is will this plug the hole? or would i just be wasting my time. cause i really can't just drop 100 bucks on a new pan when i could fix it with less than 10 bucks.

jb weld is a no no... Doesnt hold up to heat very well..

Im not sure where i found it, but there was a compound that got stronger as it got hotter... Basically does the same thing, but for high high heat applications.

I looked around for ya and found this stuff http://www.cotronics.com/vo/cotr/newprod.htm that they rate up to 2000F, so plenty hot, but not sure i'd really trust is.

I would get a really hot soldering gun (not the cheap walmart one) or a torch and use Silver solder, IIRC silver solder is good to almost the melting point of Al so you should be safe to use it...

Jbweld is an epoxy... Some epoxies get harder with heat, only problem is that they get more brittle(most of the time). My experience with JBweld has not been that great... I wouldnt recomend it for something like that.

I hate to be a vulture but I have a complete engine for sale(by the part) and the oil pan is in my for sale thread in my sig.

JB weld would be an ok temporary fix, but I'm sure you can find an L61 oilpan somewhere thats not too expensive.

i love the amount of answers that i get within a few hours on here. you guys are teh best!

well as of right now im gonna see if i want to buy this guys pan^^

or try to repair the one i have.

AND addressing the heat issue with JB Weld, don't most people use that to plug silencer holes in the s/c's?

i don't know about you but i'd think a supercharger housing gets a bit hotter than a oil pan filled with synthetic. lol

we do not use jbweld, jbweldis weak and breaks off, than u have to clean ur manifold off, this has been discussed and proven in the past, we use quicksteel, to the Op use some quick steel until u get another oil pan, it should hold up fine, clean up the outside, quicksteel it, and let it cure...should be ok

THERE WE GO.

i new there was some kind of epoxy that you guys used. i couldn't remember. then i saw Jb weld at the hardware store and thats why it was stuck in my head. lol.

u should replace it, if it a hairline crack the quicksteel with be fine, if it's a chip missing than replace it

If you're gonna drop the oil pan to fix it, might as well find a used one at a junk yard that you can pop on there and solve the problem permanently.

JB is good with heat, lol i sealed my stainless steel exhuast with it for my firebird and i got no leaks

blackbolt89

the crack itself is tiny. no chunk missing. like i can go outside and find a half dollar sized drop of oil. its not pissing out. just slow dripping.

and i make sure that i put some oil like once a week. just to keep it topped off.

Lol, I have been a quart low for about 2 months now. I have a bottle of oil in the car, just keep forgetting to throw it in there.

If it can fill a crack in my buddy's 1998 Eclipse GS-T Turbo, I'm sure it will fix your Cobalt.

Gasket maker? oil pressure will blast past it. That would be fine on the rim of the pan but not on a random crack that you cant apply pressure to.

blackbolt89

what did he need to seal with it?!

Took the car to the dealer under powertrain warranty, and said it's not covered b/c something "hit" the pan. $777 to replace it. Seems high. I found the part below on rockauto.com and was wondering if that's the actual pan or a gasket or something. It's hard to read parts specifically on their site, but they have the best prices (Iv'e found). Also, does anyone know of a write up on how to do it yourself? Dealer said it's a 2.5hr job (for them), but wouldn't think it's that hard. THANKX!! Good forum!

how big is the crack?

i had a tiny hairline crack and i just plugged it up with some quiksteel. been on for over a month and not a drop of oil has came out. like 5$ to repair it.

After seeing this forum, quicksteel is an option to me now, but I'd rather just replace the pan, since it's only $60 on rockauto.

The crack is small as well. Leaks around a quart every month or so.

We used JB Weld on the oil pan of my GF's G5 over 3 years ago. No problems. We drained the oil, cleaned it off with brake cleaner and applied very thin layers one at a time letting each one dry before the next was put on.

blackbolt89

wow that crack much bigger than mine was. my oil level never went any lower than the fill line. but i added a little bit every week.

So anyone have any links to a walk-through or how-to? Or any tips? Thanks.

blackbolt89

i can tell you what to do.

empty the pan

then basically just clean the oil pan with some nice solvent, i personally used Cobehn Spray Clean.

then use some sort of grinding apparatus, i used a wheel grinder and just ground down the area a tiny bit so that the putty would have some nice clean surface to adhere to but you don't need to do this step.

then follow the directions on the tube and apply as needed, i personally used a bit more than i thought i needed but make sure to cover the area where the crack was, allowing about a half inch to 3/4 of putty past the actual crack to make sure that you cover it completely.

let dry then refill the oil pan with 5 quarts (depending on motor of course) of your choice.

if you want more details just send me a PM and i'll try to explain better.
