Thought I would start a new thread for this. I changed out my fuel pump and then started experiencing some chatter under the hood after the drive home. Sounded like valves way out of adjustment, but with a significant knock. It increases/decreases with speed. I thought it was the new pump.
Changed back to the old pump. Noise is still there. Upon further investigation it really seems to be coming from the front of the motor, but up high. I suspected the water pump, but it just doesn't feel like that. No weeping from the pump, either.
Before all this, in the last 3-4 weeks, I had a local cruiser "guru" work on it, but have since started to question his abilities and especially his thoroughness. The truck had to go in for valve adjustment, vacuum leaks and get the smog equipment up to par. He didn't chase any of the leaks as my BVSV valves were both severely cracked. In the end he took vacuum from another source and fooled the EGR into working in order to pass smog. He also had my timing screwed up. He then left it that way and told me I was good to go. The truck ended up going back multiple time to get it right and he never truly fixed everything. The guy is a hack. That's another story...
Anyhow, I am wondering if he left something loose under the valve cover that could eventually work its way loose and now is starting to chatter away. The truck runs quite well and pulls strong, but when it heats up the noise really comes on strong.
Thanks for any help!
