Re: oil pan not coming off
you need to have the motor jacked up 3-4" for you to drop the pan enough to clear the oil pickup out of the sump

Re: oil pan not coming off
Just the side mounts.Watch yourfan blade so that it does not hit rad.Everything else will move enough. Slow and easy. Jack off the front balancer.

Re: oil pan not coming off
I think you only need to do the motor mounts. Be careful where you jack it up.
This was my turning point when I ended up pulling the motor.... s/t

Re: oil pan not coming off
If have to, rent or buy an engine hoist. They aren't that expensive and much safer. If you jack it up by the balancer you may damage it to the point that you will get an engine vibration or worse.

Re: oil pan not coming off
while I know jacking the engine up by the ballancer gets done all the time, that's a LOT of weight resting on the end of the crank. I would rent/borrow the hoist.

Re: oil pan not coming off
the engine hoist sounds good till you're under the truck trying to change the pan and you have to deal with the stabilizer legs/ i prefer undoing the towers from the frame carefully jacking on the oilpan (block of 2x10 then you take a couple of short pieces of 2x4 and place between frame rail and towers and the oilpan will come right out//thats the way the chevy service manual describes how to do the job

Re: oil pan not coming off
I got mine out by undoing the trans. mount and jacking up the trans.

Re: oil pan not coming off
I just took off one motor mount, took a small bottle jack in between the exuast manifold and the cross member, and that gave me enough clearence to get the pan out.
It rocked the motor over with no problem.
