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?
