Hey all, hoping someone has an answer. I am currently rebuilding an MC22 engine. I am starting to reassemble and when I am trying to put in three of the Lifter valve/ Valve cap they are incredibly tight to get in, I have them in the same order as they were taken out. I checked with some Prussian blue and its tight on one side of the Valve. The Lifters aren't damaged, I have tried some other lifters and they are tight. Kinda at a loss as to what could have caused it?

Hmmmm, odd one. Certainly sounds like they found the wrong home somehow

bent valve?

Interesting the valves are all seated properly but it could be worth looking to see if those 3 are a little wonky.

This is the reason it's a good idea to use lifter bore protectors, one little scratch in the aluminium will bind the lifter, the bores are a PITA to wet'n'dry

It might be interesting to see how the lifter fits in its bore in the cylinder head without any valve & valve spring assembly fitted.
