Hello everyone, I just joined this forum after getting an 87 XJ, 4.0, AW4, NP231 with 236k miles and it seems to be running strong. I just have a few questions.
The engine runs what I would call well for have so many miles on it. The engine always starts the first time, but it hesitates after a handful of cranks. The engine makes a sound that's kind of hard to describe. Its one that speeds up with rpm. It's just the sound of a tired engine. Well, I've been looking into different things I should check to get things perked up.
1. I was looking into a timing chain/sprokets because I don't know if that's ever been replaced.
2. When reading about replacing the timing chain I read that cam shafts can wear out. Have any of you experienced that?
3. I wanted to check valve clearances and adjust accordingly. I thought that valve clap might be the sound I've been hearing.
Does any of this sound reasonable to check? I'm good with my hands, but I don't have a lot of experience wrenching on engines. Thanks for any advise regarding something to revive my engine.
