removing old oil pan and installing new oil pan

[dvbagnasco]

Hey guys,

I am removing my old oil pan because i accidentally crossed the threads when I did my last oil change, which caused a leak. So I bought a new oil pan and gasket and would like to know what I need to torque the oil pan bolts down to?

Any help would be appreciated. Thank you.

P.S. It is a 1990 Toyota corolla with a 4A-FE engine, if that helps.

My FSM says 43 in-lb. Take note, IN-LB not FT-LB just in case. Most people don't have an in-lb torque wrench. 19 Bolts and 2 Nuts.

1 inch pound force = 0.0833333333 foot pounds

43 in pounds = 3.583333333 foot pounds


Seems to be a really low torque setting but that's what the Chilton's Guide say's 43 inch lbs (5Nm).

Plz correct me if wrong.

Yeah, definitely take it easy when tightening those oil pan bolts/nuts. I broke one bolt last time I was under the wagon, even though I was using a torque wrench (yes, going by in/lbs).

Yea, it's that low. They are small bolts and low grade bolts at that. It's really just a back up to the FIP gasket sealer you're supposed to use. Ever try to take a pan off with that stuff? Well, I guess you will be soon. (well not you but the OP)

I use copper permatex RTV.... I hand tighten the bolts.... start with the guide studs then work my way around opposite.... then go back through again to ensure they're all roughly even.

Yeah! Over tightening these bolts can olso deform the pan flange.
It is also best to tighten on a wide surface like this in a criss-cross patern to reduce the chance of warping it.

43 In-lbs. Cool. I was looking all over the internet thinking the information was already posted. I probably wasted 6 hours looking until I decided to finally post a thread.

Thanks guys. I really appreciate it.
