Re: Is it a blown head gasket
Sure doesn't look good, Tom. Could be a gasket leak between 2 and 3 or simply carbon.<br /><br />Blown gaskets usually take the compression lower than that, and if between cylinders they both usually go down the same amount.<br /><br />My next step would be to pull the head and look for scored cylinders, bashed pistons or, of course, blown gasket.<br /><br />It might be okay after a thorough decarb.<br /><br />Good luck.
