Noisy Lifters After High RPM Runs
After tooling around with the engine at a good boil in second or third and coming to a light the lifters clatter. If I sit at idle for a while or turn the car off for a minute or so they quiet down some. What do you think the problem is?

What oil are you running?
What is your oil pressure?
if your oil weight is less than 15w40 then you need to change it. If your oil pressure is good consider putting some ATF in the engine and driving for 100 miles before changing.

Mobil1 15W50 less than 300 miles
Pressure pegged high then middle of the gauge at idle
Engine fully warmed up.
I already ran Rislone through it before changing the oil. It didn't help.

I know having these cam plugs fall out will cause ticking at idle/warm up when first starting the car. But I do not know if having one or more pop out will cause what you are seeing (bleed down after high RPM run).
Only way to verify is to pull each cam cover.....

As mine warm up, the both go down to approx. two Bar at idle (this is below the middle) about 1/4 from bottom.
With that said I know that they are not all the same nor are they accurate, so a good flush would be in order, couldn't hurt, right?

Had the same issue and I dropped a quart of Marvel Mystery Oil in it. The additive cured the problem. I have concluded that I'll run 1 quart in it from now on with the rest of my Mobil 1 15W50 to keep things clean.
