Have a 1969 Road Runner with 440, need to remove driver's side engine mount to get to freeze plug and replace it. Do I need to remove bolts from the mounts on both sides to get engine high enough to remove the driver's side mount, or can I just remove driver's side bolts? I'm using a floor jack with some 1 x 10 wood pieces under the pan to jack up the motor, just looking for experiences of people who have done this.
 
Both bolts will make it easier. Don't forget to loosen the fan shroud from the radiator so the fan doesn't catch it.

IMO, better to lift at the pan rail rather than the oil pan sump.
 
It's been a while since I've done that, but I "think" you only need to loosen the one motor mount. You might consider a cherry-picker too if available (safety) and bolt onto an intake or at least a water pump bolt. You should have few if any problems. There's a lot of clearance in b-bodies.

To be honest the last one I did, removed all but the last bolt which was loose. Had a helper start the engine put it in gear and brake torque it. Slid the old mount out and the new one back in. Not recommended for the first timer though.

Doug, you must have a lot of faith in your 'helper'. I don't know that I trust anybody enough not to screw that up...

I wouldn't put a jack , even with a pad or board under the pan. If you don't bend the pan , you are one of very few...................MO

I've jacked up many, even with aluminum pans without any propblem. 27 years as a dealer tech.

I've been using the jack under the pan for 57 years now and never damaged a pan. The torque and pull method? I don't have the guts for that one! Wait! If it's on a lift the only one you will kill is the helper. We may try that one!

Quite a claim.. Perhaps you would post a video of how you do it. Myself and many others would like to know the procedure....................................MO

No video needed, a block of wood, good to go. Cant tell you how many damaged engine cradles I've changed supporting the engine and trans on jack stands. Working flat rate requires two things to be successful and make good money. #1 fix it right the first time, #2 you have to be fast. You learn a lot of tricks.

Not to argue---I agree on #1 by 100% ... I didn't have the time nor felt like removing the pan to fix a dipstick problem on my 440. I took it to a local Rod shop ( a good one) to have that and a few other little things done. When I got it back , the pan was dented in . I took it back and made him pound out the dent and new gasket..his expense.
If I have room, I lift the engine with a hoist or block up against the harmonic balancer................................MO

FWIW, I've seen two remarkable instances on 440's with oil pan damage from a jack. Both had similarities. That is, both had pieces of wood that were too small under the sump. And... both persons were inexperienced. One got away with just a dent and ran it. The other damaged the strainer and locked up the oil pump with pieces of umbrella seal. I'm thinking the later, (an accomplished tool maker BTW) missed a bolt and tried lifting the whole front end.
Most other damage I've seen was from folks jockeying an engine around while it's sitting on the ground/floor and banging the sump corners on the k-member.

As far as blocking these old balancers, I just don't know. I'm thinking you may risk loosening the bond between the inner and outer ring.

I guess that shop isn't that good. Why would they dent a pan and not say anything or at least repair it before returning the car to you. Not my way of doing business. Did I ever mess up, sure. You bite the bullet and take car of it.

The owner, is pretty good. Most likely he gave a "simple" job to one of his employee's , and that person didn't tell him. Really rags me when an employee does that and thinks no one will notice. I used to do all my own work, but current limitations have made that hard to do. I don't let things slide, I make sure to tell employers of inferior work................................MO
