Can you replace a piston with out removing the engine?
I have dropped a valve seat and ruined a piston (and the head)..

I want to just replace the Piston and get a new set of heads to replace the bad one and the other that may drop the seat at any time..

I would love any input that anyone may have.

I know I have done this on sb chevy's in the past...I would think as long as you can get the oil pan fully off you should be okay...but I suspect Fireman would be the expert on if this is possible.

I have looked at a bit and the mid shaft goes through the oil pan and I am not sure how to get to it. Manual is on the way, hope it has the correct instructions.

Will update if I get more info

You're more than likely looking at a complete replacement or rebuild. If the piston and head are damaged, the cylinder bore is more than likely also damaged. The engine will have to come out.

I have pulled both heads off and the cylinder does not look bad, I only ran the motor for about 20 sec after the valve seat came off.

Still waiting on the manual, don't want to take more apart then necessary.

Where did you get your manual? Does it cover AWD? Thanks
