What Happens With a Stuck Timing Chain Tensionser?

[ClayW]

I disassembled my poorly running M42 and found that the timing chain tensioner was stuck. I had to force it out from the inside with a screwdriver. As I understand it, it should slide freely, right?

What problems might this have caused?

Weird.  Yes, it should have extended on its own once it received enough oil pressure.  It was probably either faulty or somehow installed such that it did not get enough oil pressure (??).

Check your cam timing to make sure the chain hasn't jumped timing.

I discovered this as I disassembled the engine. I'm trying to figure out why it was overheating. Anyway, a new engine is almost ready to go in.
