Been having a strange experience with my new motor! Every so often especially when it is cold, I if stand on it hard my rad cap will lift and spray my engine compartment.(doesn't seam to happen when it is warmed up!) Engine is no where near hot and sometimes the rad is stone cold when this happens. My fear is a head gasket, but there are no signs of that. No antifreeze in the oil or any white smoke out of the tail pipe.  My engine builder calculated my compression at about 10:25 to 1 with the Probe dome pistons.
Car runs great, and pulls REAL strong. I can't take it back to my engine builder as he passed away, shortly after finishing my motor. My thoughts right now are to re-torque the head bolts, unless anyone has any other things I should look at (Ted, John?)

Thanks

I love the smell of burning rubber in the morning!
