305E in Illinois

[Pfroman]

Hello-

Anybody have a good guy that knows the 305E V6 engine in Northern Illinois / Southern Wisconsin? I have a crazy knock out of the blue that I can't chase down. She was running beautifully but then started a gradual knocking. Suspect some kind of lifter noise but I am not a mechanic... I do have some valve lash over tolerance which I am going to adjust next time I'm in the garage, but may need a solid valve job or other more technical help.

Thanks in advance.

An easy possibility to check is ignition timing. Maybe you will get lucky. Good luck.

Your best bet here would be to upload a video (Youtube) of your engine while it is running. There are three major areas of concern when it comes down to engine knocking noises. you have mentioned one, and that is lifter noise. Two more are connecting rod and main bearing (crankshaft related) knocking noises. One more would be a loose wrist pin knock. Please upload a video. We will then be able to steer you in the right direction.

Like Jim and George said, your best bet for a mechanic is you and us, neither of which are mechanics haha.
BUT We can talk you through just about anything and these aren't complicated engines. The only thing you might run in to is a parts availability issue. Start with the easy things.

1. Take a video and post it up on youtube or rumble or some random site.
2. Buy a 10.00 timing light and check your timing.
3. Check your oil level because low oil will definitely give you a knock/tick.
