If your father-in-law replaced the sleeves in the engine, try to find out how easily they installed. We have seen it more than once that a person rebuilding one of these engines just slipped the sleeve into the bore with litlle resistance. The consequence is that the sleeve will move up and down with the piston causing a heck of a knock. If allowed to continue the sleeve will eventually break up and end up in the oil pan.
If he had the head planed it then becomes necessary to install two head gaskets to keep the pistons from hitting the head.
This 8n should have adjustable tappets. remove one of the side covers behind the exhaust manifold and look at the lifters. If you see a small bolt head proturding from them, then they are adjustable. You need a special wrench to hold the lifter while you adjust the bolt.
I am at a loss as to what caps you are refering to on the tappets since the tappet (if non adjustable) or the screw head (on adjustable tappets) operates directly on the valve
I hope this helps you find your problem, but do not allow the knock to continue or it certainly will cost you more money than fixing the problem now.
: My father-in-law has an 8N that he rebuilt the engine on. It runs great but it has a very loud ticking noise. It sounds like valve noise but it's the loudest valve noise I have ever heard. It doesn't have the ajustable tappets. I do know that when he had it apart he didn't keep track of where those little caps on the tappets came from. They got all mixed up. He did install new valve guides. Could a valve guide be jumping up and down or is the tappet clearance just really messed up. He doesn't seem to care about the noise but it really bothers me to hear a brand new engine run like that. Thanks for any help. Mike
