Hi all,
On my Alfetta GT track car we're starting to get bubbles into the radiator overflow and we suspect there is compression leaking into the coolant. The compression on the motor seems very strong at 200-210 per cylinder and the last time I replaced the head gasket when it was doing this the machine shop o-ringed the head. I'm using Reinz head gaskets now.
Motor is a 2LTR with 1mm bored liners and JE 10.5 to one pistons. the head's been cut a bit so the compression is probably up to 11:1 now.
The bubbles start as the motor gets fully warmed up on the track and not when cold or only slighly warmed up. I suspect a leaking head gasket or maybe 1 liner not protruding corectly compared to the others. When it's done this in the past and I've replaced the head gasket it does not show where it's leaking.
Any other causes or sugestions on things to check?
