Oil Pan - Stripped Threads

Post by rodo »

Thought I was done with the oil pan install and then...the two bolts at the front of the pan. Both holes stripped. Weighing options. Anyone done a fix with the pan still in place? I'm open to suggestions...any suggestions.

Those bolts at the front of the pan tie into the front crankshaft oil seal cover. (Aluminum). You could replace the plate that holds the seal, or drill and tap to next size up.

The best approach would be as Odoyle suggests, but you could try a couple of other things first. Try a slightly longer bolt, as maybe there are still some threads at the end that could hold. Don't tighten super tight of course. Another option is a thread sealant or a mild version of a thread locker. There is no oil on the other side of those bolt holes, so all you need is enough "grab" to hold the oil pan at the front. I would NOT suggest using a permanent thread locker.

Not ideal, I know, but it might work well enough.

Thanks Gents, but I found a better solution, quite by accident. The top of the bolt hole is open! So slightly longer bolt with a locknut atop and all is good in the world. Can't believe, for once, I have found something actually easier than the usual job.

Well, now we'll see how much leaking it does when I fire it up...
