Changing Oil Pan Seal
I know this has been covered, but I searched and couldnt come up with anything.
SO I have to change my oil pan gasket. It LOOKS like I can do it without jacking the engine up....but I dont know if I will be able to clear the oil pump enough to get it off.
Had anybody attempted it?
Thanks!

On my LT1 I got it off without raising it but knew then that it'd be a bear to put back on that way. I raised it maybe an inch and a half and it made all the difference. I just put some wood blocks between the mounts and frame until it was back on.

Leave the engine mount alone. After taken out all the oil pan nuts and try to drop the pan if the pan is stuck rotate the crank a little so it will have enough space to drop the oil pan. I have no problem with the oil pump in the way so your shouldn't either. To put it back you need to use some gasket sealer on four corner to kinda help the gasket to stay inplace. Its not that bad. The car has to be raise high enough so you can get in and out though. I think mine was on one of those plastic ramp.
C-4 oil pan gasket is one piece and it shouldn't be leaking and its reusable. Check else where for leaks like the intake manifold before changing the gasket. You might be looking at the wrong problem.

IF( I don't really know) the C4 oil pan gasket is a one piece like quoted above I would drop the pan and not take it out. Felpro makes a one piece blue rubber gasket(not positive if the make one for the C4), It comes with four plastic screws(very long,2 1/2" or so).
Drop the pan, while its hanging remove the gasket, clean mating surfaces as best as possible without getting any debris into the pan.
Slide the new gasket over the pan, instead of under the crank and oil pump. put the 4 throw away screws in ( 2 front ,2 rear)to hold the gasket on the block,
slide the pan up, there's notches in the plastic screw that'll hold the pan up so you can start the remainder of the screws. Once there in remove the 4 plastic screws and put the old screws in.
AGAIN THIS WILL PROBABLY WORK ONLY IF WE"RE TALKING ONE PIECE GASKET.
I just did the exact same job on my 95 Bronco.
If it works let me know. Hey you got nothing to lose.

Well..yes I was able to do it without lifting the engine..just had to remove the crossbraces on the frame.
OK...this is why it was leaking...I shouldnt be admitting this..but I put a new cam in about 2 years ago...and when I took off the timing chain cover, I ASSUMED it was a 2 piece seal.....so what do I do...but pull the sh*t out of the gasket...before I realised it was a one peice...well I caulked it up and hoped for the best. lol...well...I had nothng to do this weekend....
Thanks for the replies!

Some C4 guys can drop the oil pan with the front cross braces in place, and other need to remove them. Not sure what gives, but on my 86, the pan would not come off till the cross braces came off first. As previously posted, the Fel-Pro one piece gasket is the way to go for you guys out there that need to replace yours. The 4 plastic studs that come with the gasket hold the pan up against the block for you while you install the rest of the pan bolts. I installed one on my 86 several months ago, and to this day, the mating areas arround the pan are absolutely leak free. I crawl under the car periodically to check for leaks, and so far so good.

Clearing the oil pump was no problem.
All in all, pretty easy job.
