had high cylinder compression used 2 treatmeants of seafoam and compression is ridiculously good for 91 with 186k now.

weird thing now is after i shut the jeep off it sounds like an audience of little ppl in side my valve cover claping for like 15sec then it stops.

looking in side through oil cap i dont see anything moving but i can hear it...so what am i hearing and is it a good thing or a bad thing?

 

LMAO its ur lifters saying thanks u made me run so much better

 

There are no lifters under the valve cover.

 

popping as it cools?

 

lol nice. i only used it in air intake tho...dont know if that matters or not. crankcase will be before next oil change.

what is actually making the lifters move after its off?

 

Nothing moves once the engine is off (except for fluids, mainly oil, draining back).

 

Hydraulic lifters-Stop when engine is off.

.

 

I'd guess your just hearing the engine oil run back down to the drain pain. Mine gurgles for a while after being shut off as the oil drains back down. Once the engine is off nothing should be moving inside the motor anymore.

 

the sounds is more rapid and only lasts a sec or two. seems to be goin away.
