Re: 3.0 l cobra 94
compression ? no1 151 no2 30 no3 60 no4 150 how is this possible plus poping in intake any help thanks pete
Howdy,
Well,
Low compression can be from many things including stuck/burnt valves, broken piston or rings, blown head gasket, cracked head.
"poping" in the intake might point to burnt or bent/warped intake valves.
You might do another compression check using a differential pressure (leak-down) check.
This way you can possibly identify where the leaks are.
Either way, you'll probably at the minimum, be removing the head.
Take pictures!

Rick
