Replace Oil Pan Gasket engine in the car

I have a small oil leak on my ZZ454 Crate Engine, and I finally tracked the mother down to a split Oil Pan Gasket. Apparently I messed the gasket up when I did the cam swap (to a mild ZZ502 Cam).

How bad is it going to be to replace the Oil Pan Gasket while the engine is in the car? Can I drop the pan and snake the gasket under the oil pump pick up? Ideas? Tips? Since the transmission is a 700R4 I don't have a lot of room in the transmission tunnel to lift the front of the engine up with my shop hoist.

If I have to actually pull the engine completely out of the car, I'm just gonna swap in a 540 short block.

I never like to rain on anyone's parade, but although it can be done(on a stock unmodified car) with great effort and difficulty, I'm gonna go out on a limb here and say a 540 short block is in your future.....(if that was serious).... Your going to want to lift/raise the front of the engine as high as possible, to clear the crossmember so you can get the pan far enough down to get past the front main.....Trust me when I say.... this is not a fun project doing it in the car.....Been there and done that. Maybe when someone is in their 20's with a bunch of friends helping out. But I have become a large advocate of yanking the engine in favor of the Heavily Labor Intensive Alternative. As always just my .02....

Ideas are like children: there are none so wonderful as your own.

Re: Replace Oil Pan Gasket engine in the car

I've done it. To be honest it is easier to pull it. I had to pull the tranny, remove the flex plate, out the trans back in, then I could get the pan out. Yours should be a one piece , but you still have to get the gasket over the pickup with the windage tray in the way,

Couple of junkers and a few clunkers.

Re: Replace Oil Pan Gasket engine in the car

Yup! I agree with Lang ss and Andy. I have done it both ways.Iin my teens twenties and thirties when I was full of piss vinegar and extra energy it was no problem now in my late 60,s I pull everything much easierand a lot less wear and tear on the carcass. Alex

Re: Replace Oil Pan Gasket engine in the car

It may be easier to pull the body so you can raise the engine, just kidding. I had to change the oil pump on mine while it was just on the frame, and I still had to raise the engine about 18 inches so the pan would clear my flexplate/torque converter.

Re: Replace Oil Pan Gasket engine in the car

Quit thinking about, it will take less time and its so much easier to pull the engine and do it out of the car. Went through this exercise this past winter.

progress has little to do with speed, but lots to do with direction

Pull it. It's the perfect time of year to do so, it'll make a good winter project. Unless your garage isn't heated, then I wish you luck!

I have been there, it's time to pull the engine. That's all there is to it.

Re: Replace Oil Pan Gasket engine in the car

Just think of the upside of pulling the engine. It will give you the opportunity to detail everything on the engine and everything in the engine bay quite easily. I think you found your winter project.

So you like oil stains on your garage floor and streaks all over the bottom of the car?.......

When I sits, I sits loose.
When I thinks, I falls asleep.
