Default How do I remove the Oil Pan?

Didn’t realize it until this evening that my 89 has a one piece oil pan gasket, or at least looks like it does. I have a new pan gasket & need to remove the pan. I removed the bolt to one motor mount but still can’t raise the motor enough to drop the pan. The timing cover is off & I’m ready to put it back on but pan 1st.

It looks like I need to pull the other motor mount bolt to lift the engine more. However do I also need to remove the two cross braces that meet at the front of the oil pan?

Thanks guys!

Rotate the motor to #4 tdc and try it.

Looks to me like the front main cap is what’s blocking me from pulling the pan. Then again, so is the other cross brace I need to remove on the drivers side and even the steel line, brake I assume.

Probably still need to lift the engine.

I have 86 and when I took the oil pan off I rotate the engine a bit and the bottom immediately dropped. I did not touch the engine mounts.

I lifted the engine some & the pan finally came off. I had removed the passenger side angled support but not the left. Nor had I removed the brake line, which would have helped. Since I already had the motor mount disconnect it was easy to raise.

The only thing hard to get off now is the very back of the pan gasket. I am assuming it’s RTV that is holding on like crazy but wanted to confirm before I pulled like hell!

The brake line does not run along the oil pan. You must be referring to the transmission cooling line.

It is very likely RTV. That is not the original oil pan gasket BTW, someone has been in there before....

I pulled mine today for a oil pump replacement. Removed both of the cross braces, turned the engine to #4 cylinder to top dead center, pulled the starter and removed all of the oil pan bolts and the pan dropped right out. No need to raise the engine. I have a 86 4+3.

This is the Brake Line that goes in front of the oil pan.
