oil pan change
can any one give me some info on changing the oil pan can it be done with engine and box in the car, i heard u have to set timing mark up?
car was jacked up and jack sank over night resting the engine on a axel stand which put a dent in the sump, its not bad but its where the oil pump is so worried to leave it

It can be done. You'll have to lift the engine off the chassis mounts to get clearance, which usually means it's a good idea to take the distributor cap off first. You need to turn the crank to a point where the front of the pan can get by the crank throws & counterweights.

Re: oil pan change
could you post a pic of just how bad things look
an oil pan is not a very hard job to do
if you are already there with the pan off go ahead and change the rear main seal if its a 2 piece seal on late model blocks
change the pump as well

Re: oil pan change
Sometimes it helps to unbolt the engine mounts, but only lift it on one side. The slight tilt can help with wiggling it out between the frame and crank weights.

Re: oil pan change
unless the rear main seal and pump are less than 10,000 miles I would replace
after you see the amount of work you have to do in order to get the pan down you wont want to do it again
I would go ahead and change the chain as well
dont get me wrong I just like to replace as much of the wear out items as possible
not a fix it as it breaks kind of guy

He has a one piece rear main seal. a decent amount of work to change the seal over just an oil pan. Same for the timing set. Why take off all the accesories and whatnot to change a timing chain thats ok? Personally, i would turn it over and seeif anything is rubbing, then start it up and check the oil pressure. If it had adequate pressure, and kept it during acceleration like normal, I wouldnt mess with any of it. Its a dent, big deal.

Re: oil pan change
i think its probably ok its not a huge dent but its where the oil pump is so would like to check it out.
this is a second hand engine ive put in that im gradually getting sorted, i turned it over by hand a couple times today its definatly not catching the sump.
the engines been sat a long time and its got no dizzy or inlet manifold on at the mo, should i be able to feel much compression when turned over by hand? it feels smooth i guess when its together and i go to start it, it will build up compression

Re: oil pan change
While I understand what you're saying, changing the rms requires separation of engine and trans and removal of the flexplate.
The front seal and timing set requires the removal of the gear on the crank. To do this you need a puller. I don't know if there are smaller ones out there but my puller wouldn't fit unless I remove the radiator.
Lots of extra work.
