Question Chevy 350 Intermittent Lifter Tick

My daily driver, 1993 Chevy 1/2 Pickup with 190K miles on it has an interesting issue that seems to only occur when the weather outside is above 80 or so degrees -- basically summer time. Beginning last summer, I get a lifter ticking on the drivers side that is pretty bad and it robs the engine of quite abit of power. It started again this summer a couple of weeks ago. It never does it on initial startup on a 'cold' engine, but may just start after it warms up. Sometimes it'll just stop after awhile and the power is restored.

I'm assuming a lifter may be bad. Has anyone ever experienced something similar? As soon as I find time, I guess I'll need to remove the value cover when it's happening to determine with cylinder/valve and then proceed to remove the intake and investigate more.

Could it be a lifter going bad intermittently? If it was a valve spring, I'd assume it would happen all the time. I'm open for ideas.

My son's and my project.

Haha..I had a 93 Silverado that did that exact same thing. Mine would do it after a warm start....sometimes once every 6 months, sometimes 3 times a week. It happened from 140k till 215k when I sold it and never got worse. I wouldn't worry too much about it. The power loss is probably the knock sensor picking it up and retarding the timing.

It's likely a lifter that's failing to pump up with oil...it may have some dirt in it. Pretty much with 190K you just live with it until that engine dies..which may be a while.
