Inlet valve - replace or reuse?
Posted: Wed May 17, 2017 7:20 pm
Just stripping a big-valve head ready for skimming and I see that no. 4 inlet valve has some slight pitting (after cleaning off the carbon) on the inside face (ie combustion chamber face, not valve seat). I presume this occurred as a result of the head gasket failure and is related to water entering the combustion chamber. The seat and sealing face of the valve are both fine and show no signs of damage. A compression test prior to stripping was good - the head gasket leak into the cooling system only became apparent when the engine was hot and running at high rpm - so the seat to valve seal was obviously ok. All the other valves are fine too. As I have no spare 1.562" inlet valves in stock, I'm wondering if its ok to reuse it. Normally I would just replace it with a new one but this rebuild has both time and budget constraints. What, if any, are the likely dangers from re-using this valve?
