Need help replaceing exhaust valve

I hava a 2003 f350 6.0L it has one burnt exhaust valve, can you replace it by droping the oil oan and pulling the piston, or must you pull head off?

It'd be easier to pull the head. It's probably quicker, plus you'd get a chance to check out the valve seat to make sure nothing is wrong with it either.

I don't think it's practical to go up from the bottom. 1) I don't know if you can get the pan out of the way on a 6.0L. 2) dropping a piston to get to the valve presents a problem once it's out. You'll have to get it back in. Will you be able to have a ring compressor up there so you can slide the piston back into the cylinder? 3) What if the valve seat is messed up? You'll still have to pull the head.

This is just my opinion.

Well my thought was its 20 hours (book time) to pull the head and 4 hours to r&r the oil pan , plus I just bought this truck, and cannt afford to dump atlot of money into it. Need it going soon to pull a small travel trailer 1 hour. So im,looking to see if you can drop one piston out with out pulling the crank right out. dont want to spend my holidays pulling heads.

you can pull the heads with the cab on and if its just one side that will shave some time off the whole process. only takes a few hours to strip all the parts from the heads up. If you have the parts and dont need the seat re-worked, you can probably get it done in a weekend... just a thought.

how do you get a piston and connecting rod out past the crank shaft .. not that pulling the pan in a 6.0 is a breeze anyway but just curious

because the crank center line will be in the way can you imagine trying to reach back up to reinsert the valve ,, whew that sound tough even with no crank in the way
