My oil pan leaks and has big dents, so I plan to remove it and replace it on the weekend.
 
Has anyone done this recently? I would like some tips and advice. My car has dual exhaust pipes, so the exhaust is not in the way.
 
I plan to put #1 and #2 at TDC so crank will be out of the way at front of pan.
 
I plan to drop the pitman arm and let steering hang down.
 
Also does anyone know if I can replace rear seal with minimum effort while I'm in there?

You should be able to get the pan down with the steering out of the way. Are you replacing this a factory style pan?

Jack, I'm also needing to replace mine. I found a nice stock replacement on e-bay. A friend that builds motors for a living insists I remove the motor as the rear main seal is such a PITA to do in the car. I'm doing the front end over also and it gives me a chance to clean and repaint the front end with the motor out of the way.

Let us know how you make out I'd like to know how the real seal works out for you.

Here is a nice article on the complete "how to" on the seal replacement -http://www.corvettehacks.com/article5.html - they make it sound pretty straight forward and easy if you can get the car up in the air high enough. Wouldn't want to do this job with the car only three feet in the air; so therefore I paid a shop to do mine two years ago. They did not remove the engine, they did it a shown on this link. It didn't leak for about 3 months but now it is back again PITAConfused 
Good luck with it in either case

Well lets think about that, if you get it done.....if....you for sure will be stressed out, you will have placed enough coin into the "Swear Jar" to buy a 12 pack. So for sure you will want to drink.
Problem is...will the wife want to go out to dinner with someone that stinks of motor oil? For sure it will take three days to get the oil out of your pours and lets not even mention the sliced up body parts.
Yeah diner for sure in the vette........at the local SONIC Rolling On The Floor LaughingLOLLOL
Please oh please let us know how it works out fer ya..................................Evil Smile

Don't let them scare you off!  Removing and reinstalling the pan takes a couple of hours at the most.  And sometimes the seal takes an extra fifteen minutes, if it goes well.  Loosen (but do not remove) all of the other main bearings to let the crank sag a bit, then just push the old seal out and the new seal in.  Sometimes it helps to rotate the engine to help pull the seal along.  Do not line up the ends of the seal with the block, but rather offset it a quarter inch or so.  Do the same with the seal in the cap.  Then re-torque everything and put the pan back on.

Listen to Larry, he is right. Slow and steady wins the race, put on some tunes and take your time. Good luck with it.

If the pans are the same as 72 with LF dip stick with PS I have two restored dentless pans for sale, what did you for the e-bay pan?

Ok I'm halfway there. The pitman arm was easy, just two bolts. Pan can out no problem. Bid surprise inside; looks like plastic pellets. Was this the remnants of an plstic timing gear?
 
I thought all Corvette engines were 4 bolt mains, this engine has 2 bolt mains.
 
There are large letters stamped on the bottom of the engine, does anyone know what these are for?
 
Tomorrow the new oil pump and pan go on.

I suggust before you bolt the pan back on you change the timing gear set so latter down the road you don't have to pull the pan and whatever because of engine damage caused by a failed timing gear set, whats the red stuff on the rear main seal and I hope you didn't cut the seal so it flushed up with the main cap.

No time to be penny wise and timing chain risky - it's extra time and work you didn't plan on but I would not chance it. While you're at it, a fresh cam and litters usually is the next thought if you're doing a timing chain on a high mileage motor ( and a bit of a performance grind is always nice) LukesVette2009-10-17 22:12:58

The red stuff is sealant. I installed the rear seal just like Larry said.
 
Put in a new oil pump while I was there and the pan is on now. While I was in there, I also replaced the timing gear; see separate thread on that.
 
Hopefully there are no leaks.
