Can the oil pan be removed on a 402? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

REPO1 · 04-02-2002, 10:45 AM

Is there enough room to get the oil pan off the engine on a BB402?

Or does it need to be jacked up or anything?
I would like to fix the oil pan/rear seal leak and maybe check a couple of bearings while I'm in there.

Yes it can be done,just a messy sucky job,my opinion be easier/faster to pull motor and put on a stand if you have the time,space,tools.only takes a couple hours.

Thanks for the info. I will probobly just try and do it in place. I am used to working on a '97 Camaro, so this will be a piece of cake. I just wasn't sure if there was enough room to slide it out of there.

Had to do it on mine to reconnect the oil sump the previous moron didn't install correctly. I pulled the bolt out of the driver's side motor mount and used a 2x4 on end on top of the floor jack to lift the engine enough to get the pan past the flex plate. I used the power steering bracket (I think) on the front of the engine to push up on. The pan won't come out of there unless you lift the engine a little.
