I heard kerosene would help that. Ive never tried it. The MMO worked in my Jeep. Pulling the head and replacing the lifters should only take a day if nothing goes wrong.

Ecomike said:Correction, had a 1/2 can of seafoam. Seafoam is very volatile, evaporates pretty quickly at engine oil operating temperatures. It is used for fuel injector cleaner.
88XJSport said:Thanks! Next time I wont follow the directions on the can.
Anyways, if it did evaporate, its not there anymore... I might as well try ATF.

88XJSport said:I still cant imagine how a heated up manifold (expanded) can mimmick a lifter tick.
I understand when the engine is cold, the manifold can sound like a lifter, but not when the engine is warm...

88XJSport said:Can a manifold tick come and go like mine does???????
It seems the tick is right near the valve cover.....but then again so is the manifold...
So does it come and go, or is a manifold tick constant?
88XJSport said:It seems that after running 2 sessions of a quart of trans fluid and 5 qts of oil for the past 1000 miles, (500 each) seems to have quieted the noise down about 50%. The noise is still there, but will still come and go as pleases. When I rev the engine to about 4000, it will stop ticking. Also, just idling, makes the noise disappear as well.
When the ticking is going on, there is a definate change in the exhaust note, and the engine faintly chugs. Ive determined with a stethescope, that the noise is directly under the valve cover, and after changing my exhauhst manifold like people insisted on, didnt help the ticking lifter.
Would It be easier to just swap a new head on the block? Rather than mess with new lifters, etc? Any other suggestions?
valve may not have been closing all the way giving possible poor performance(lack of compression in that cyl.) Hopefully not an ex. valve possibly burning valve, but could explain tick from combustion in cyl and gasses passing through.
That's my best assumption.
