    Got my Jeep stuck in a snow drift. high revs for a bit only 4 grand rev limiter tapping away (really 3800)

    Rebuilt L-head with less than 300 miles. all cylinders were sleeved. Hardened valve seats intake and exhaust...pretty much over the top rebuild was done. Head decked .030.

    When I let off the gas one time the noise started. Sounds coming from the front of the engine. I open the hood and spot antifreeze on the water pump, and bottom of the hood is wet. Antifreeze in the spark plug reliefs on the head on cylinders 1 and 2.

    Sounds sorta like a misfire, but I checked that (pulling each wire off individually and listening.) normal exhaust pulses out the tailpipe.

    I have no frothing of the oil either, or any evidence of antifreeze loss.

    Just the noise, at all engine speeds.

    Only visible evidence is bubbles coming from the head gasket, on the front left of the head, when the engine is being revved.

    NO noticeable loss of power. or idle fluctuation.

    --------------------------

    I am yet to do a compression check, or vacuum check. I have a spare head gasket and everything I need to do the job, which will talk around 2 hours to do. I would like someone else opinion on this before I swap the gasket out.

    Thanks.
