loose valve seat... Options

How much should it cost to fix a loose valve seat?

[Dave_Darling]

Heat (either heat/cool cycles, or overheating) is the main reason that valve seats get loose. Both heads are subjected to pretty similar heat conditions. So it is false economy to not pull both heads and have all four intake seats done, at a minimum.

Replacing the seats means a new valve job, of course. And it would be silly not to replace the valve guides while the valves are out. And the valves should be checked to see if they need to be replaced.

And, of course, the heads can crack--it seems like most 2.0 heads are cracked somewhere, so those need to be cut out and weld built up so they can be brought back to the original shape. At the very least, the heads should be inspected for cracks...

It isn't hard to spend several grand on that work.

The price goes up a fair bit higher if you're not the one turning the wrenches.
