Lifters pumping up and holding the valves open is usually caused by
excessive oil pressure, blocked channels in the push rods or rocker arms, or
the valves are sticking in the guides. This is fairly common in engines have
been overheated or the really bad gas gummed up the valve stems. All was
good until you shut it off and the guides cooled and contracted around the
gooey valve stems. BTDT!

Hi Ken and All
It is not an ignition thing. Plenty of spark, Plenty of air and plenty of
fuel.
Just spins like the pistons are not attached.
I have had a overcharge on lifters on a 1.9L. What happened with that one
was you would drive it and it would just all of a sudden run on 3 cylinders
and then over to 2 cylinders. It lead to a full rebuild and absolutely
everything was perfect and well within tolerance. After back together it did
it again! Someone on the list said try checking compression and find the
cylinder with no compression then adjust the valve with 0 gap on the rocker
arm to the valve. Did it and bingo bango instant compression.
Also had another issue with the wiring harness that also lead to the rebuild
so it was not just that.
We are letting it sit for a few days Probably this weekend will spin again
and pop a valve cover.
Personally I have never seen the complete lack of any compression we at 1st
thought it was a bad bendix on the starter and it was just spinning free.
Also we were playing with it. No we did not change the oil OR put new gas in
it. OLD VWs love to run on "Gas Concentrate"
Sorry had to toss that in.
We didn't think it would not run and we were not taking it on the road or
abusing it. My guess is sticky Valves and lifters. We will get some Fix all
Sea Foam and Marvel Mystery Oil to beat it up with and go from there.
Just wanted to toss this Out there for the powers that be.
Again had nothing to do with ignition or air or Fuel really. Btw the guys
bus ( New to him ) is a Certified Mechanic so nothing scares him at all but
we both stood there looking stupid, Or More Stupid as my Girlz say!!
All in good fun!!
