stripped holes on oil pan

[hurricanecris24]

okay so i just installed my evo3 turbo and when i installed the oil return line it was leaking a little so i tightened it more than the bolt stripped the oil pan what can i do to fix it? get a new oil pan?weld it?

Yeah you can get a new pan, you can drill and re tap it to a bigger size. If they make helicoils that size you can do that too.

 

[caboose]

you could weld the hole then retap it.

Take the oil pan off, get bolts slightly longer, thread bolts from inside out, weld bolts in, voila you now have studs and will never strip them again.

For now, find a 1/4" x 20 bolt the correct length and thread in it's place. The 1/4" x 20 bolts are just slightly bigger than a 6mm x 1.0, and tend to work well on stripped 6mm holes.

okay thanks guys for the info, i also have a used oil pan laying around but the oil pan thats on the car looks like it would be hard taking off without taking off other things around it

 

[JusMX141]

Just to be sure, pull the bolt out and make sure it's not the threads on the bolt that are stripped. I've had that happen a time or two.

Its not the bolt I tried two different ones and the bolts just slide in the hole that's how I know its the hole

You must have been really cranking on those bolts to strip out that piece of reinforcement. With a new gasket, goodentight is more than enough.

yeah i over did it

Great strengh of hercules!... Well to take out the pan, it won't be as hard as an awd. All you need to do is remove the down pipe, pop out the axle, remove the dust shield on the trans and I believe (for fwds) you need to also remove the crossmember.

Just whatever you do, don't snap the bolts that hold the oil pan to the block! I always get soo nervous doing it. I refuse to do it to any friend's car. And make sure you keep track of the bolts, two of them will be shorter and go under the timing belt.

 

[hurricanecris24]

Dang that's a lot of work for me someone has to do it

 

[dsmfa9nutter]

Lay a big bead of rtv around the oil pan (circle the mounting holes as well), let it cure for half hour, put it on the block and thread the bolts in a little way (about 4 threads worth, it's just to keep the rtv out of the holes), let it cure for another hour, put the socket on the extension and thread the bolts in as far as you can by hand by only turning the extension, do not use a ratchet. Let it cure for 24 hours, put a ratchet on them and turn until they're snug and that's it. Voila, an oil pan that never leaks.

Screw all the above advice. Take off your oil pan and weld a -10 AN bung in place of it. Never have to worry about that stupid design ever again.
