Default How Much Torque on Oil Pan Bolt?

Changed oil today and torqued down the oil pan bolt pretty tight with my ratchet. How tight is too tight. I changed the oil with the car on the ground so it's not like I gave the bolt my full body to torque

I usually use my German tq wrench on fasteners like that. Even tq across the sealing surface is more important than the actual number, especially with a liquid gasket.

Liquid gasket? Does your car not use a crush washer?

As for the torque spec, I'm with Matt - guten tight. I'm pretty anal with using a torque wrench to get the proper torque on things, but pulling out a torque wrench for the oil drain plug seems a bit excessive.

According to the factory manual for my '02 Impreza, 33ftlbs (44Nm) is the spec'd amount of torque for the drain plug bolt on the SOHC engine.

Just to see one time I used my tourqe wrench and the ring crushed at about 31lbs so I'd say that just tighten till the rings crushed and you should be fine

I had to wrestle mine off once. must have had 100lbs of tq on it. Last time I let jiffy lube touch my car.

I assume they over tighten it so that the chances of it coming out and them being liable for the damage is deceased.

my buddy had the treads on his pan half way stripped. luckily it wasn't the bolt. An impact gun on a regularly serviced bolt is just ridiculous.

Impact guns other than untightening is a bad idea

I had the same issue with it after a dealer did the 60k. You'd think they would know better.

I read the original post and saw "oil pan bolt" thinking the bolts that hold the pan to the case.

Thinking people know anything is setting yourself up for disappointment.
