<TABLE><TBODY><TR><TD vAlign=top width="100%">Can the pasenger side head be replaced without removing engine? Can a piston be replaced on a 5.4L without removing the engine? I am contemplating purchasing a truck with a valve or piston issue and trying to get a feel for the repair time. Is it easier to remove the cab to remove heads and/or the engine like I have heard? (vs pulling the engine out the front)

Thanks,

The engine is in a F250 super duty

 

This is the right spot! This forum doesn't get the traffic the SD forum does but this is the spot for the answers. Just hang in there and some of these engine guys will be along shortlly.

Right Guys!!

 

There should be enough room in a SD. The oilpan is the only concern as fas as getting the piston out. The heads can be removed in a F150, but it's really tight.

 

Pulling the engine isnt bad at all if you have a engine picker... just pull the intake manifold and disconect everything on the engine... you will need to pull it to put a new piston in. This can only be done from the bottom

 

Well it IS POSSIBLE to replace a piston with the engine in the bay..... you'll have to unbolt the tranny and engine mounts and actually jack or lift the engine up as far as possible to deal with oil pan clearance....It really isn't TOO much more trouble to just pull the engine, and after that, everything is MUCH easier..... Removing the heads is something I would go ahead and leave the engine in place for unless you were just feelin' frisky
