Noisey Lifter

Marvel mystery oil works great for just this kind of thing.
If a lifter has a build up of any kind it cannot work smoothly and is always worse with a cold engine.
All lifters bleed off oil but sometimes the plunger will stick and not pump up right away causing a loose push rod and rocker condition.
If it goes away when the engine heats up then you will be fine.
Put a hole quart of Marvel in the oil and change it to a lighter 10w30.
good luck.............:thumbrig:

Adding Marvel to the oil has a tendency to "Wake The Dead".

Little bits of stuff that has found a place to sleep, and harm nothing, can be woken up and circulated through the engine scratching and scouring surfaces.

This amounts to burning down your house to get rid of roaches.

This is just what happens when someone gets a classic car or truck that has always had "Non Detergent oil" and the first time the new owner changes the oil, they use oil with detergent in it.

A short time later the engine starts to smoke and act like a worn out pile.

The reason is obvious, all the crap that found a little nook or cranny to sit and sleep was woken up and is now flowing through the engine.

Now you will say, "But the filter will catch all that stuff".

Not before it does harm, I know these things..............

Because I have seen it with my own eyes.

It is best to treat just the offending lifter with Kroil, in nearly every case this is all that's needed.
