I finally got my Barn Find 74 2.0 started up after fixing major oil leaks. Also did a valve adjustment, reset the Dwell and timing. I’m hearing a motor tick during idle? I’m still in the learning phase, so do I have a valve out of adjustment? Is it safe to drive or do I need to address it immediately??

It's hard to tell without actually hearing it, but these engines do tend to make a lot of noise and clatter.

It sounds just like a lifter tick on an old Ford Truck I had. Just wanted to check that I didn’t get a valve too tight??

Does it have hydro lifters on it? Recheck valve adjustment. I'd leak it down if you have the tools, maybe it will give a clue. I had a ticking noise and dropped a valve seat. That was fun.

Look for exhaust leak at the heads, make sure the nuts are tight.

But not too tight. It’s very easy to pull the studs.
You should be able to tell which side the ticking is coming from. Double check your valve clearance.

Does the noise change if you run the engine for several minutes? If you have hydraulic lifters it could take a while for them to fill with oil. If the noise starts to lessen after running the engine for a while you probably gave hydros. Only way to know for sure is to remove one of the lifters.

Any chance it is a worn out alternator belt? Sometimes sounds like a tick....

Exhaust valve leak can sounds just like a loose valve. Start at 10lbs, and work you way up to 14lbs on each nut. You'll probably find at least three loose.

I'm working on memory on the 14 lbs. Please verify first!

Thanks for the info! I haven’t isolated right where it’s coming from but will recheck my valve clearances and possible exhaust leak. Also Alt Belt? The tick is constant at idle upon start and after warm up. Motor drowns it out at higher RPMs of course. Will try to isolate it better but good info on where to look! It’s factory stock 2.0.

you could also pull one spark plug wire at a time and see which one lessens the tick, so then localize it to a specific cylinder.

I have a piece of PVC pipe about 2-3 feet long X 2". I use it to isolate sounds. be careful not to get it hung up on anything or you could loose your ear. It's a great, cheap tool.
