Look closely on the block, at the pump-side head bolt hole between cylinders 3 & 4; my magnifying glass sees what looks-to-be some suspicious lines going out to the water jacket & to the oil feed hole. OTOH it could just be my silly eyes & pessimistic brain. Hope I'm wrong!Back when they were new, our delivery guys cracked the block right there on an almost new '80 Rabbit "company car" 1.5L... the third time they blew the head gasket! Nice guys, but idiots, mechanically speaking.J.R.SoCal
have the valves ever been adjusted?valves that are out of adjustment will make for HORRIBLE compression.. oil wont really make the numbers go up much either, when its valves.
That is right, the shims dont have to be the same on all the valves, just build each shim pack to land in the range specified for each individual valve. i always aim for the tighter end of the clearance.
