Engine rebuilt a few years back, less than 10,000 miles on it.
A few weeks ago was out driving then bam, runs really bad,
compression is 150psi in 1 & 2, 25psi in 3 & 4.
Got the head off, copper head gasket blown between 3 & 4.
I check the block and head surfaces with a machinist square, everything is good.
put in a new payen head gasket, new exhaust/intake gasket get it all back together
and now it runs very poorly/erratic. especially under load.
Everything was torqued to spec and valves adjusted to .015 cold. Distributor had been rebuilt recently, but not seeing any
issues with that.
Compression tests same as before but 3 & 4 are back up to 140 psi now.
Spark plug wires are on and in correct firing order. Checked coil to distributor wire,
checked coil wires.
Any ideas? Engine was perfectly running / in tune prior to blowing the head gasket.
