hi a few weeks back a bought my first p38 4.0 l knowing the head gasket was on its way out (apparently). so yesterday i pulled it apart thinking it would be a pretty strait forward job as soon as i started it didnt look like it was going to be as strait forward as i would like,the cooling system was full of somesort of gaket sealer and the offside head had already been off and replaced with new bolts and new gasket where as the nearside had not been touched looks to still have the original landrover head gasket and bolts. the offside which has already been messed about with i think its cyl 5 which has a clean piston and combustion chamber but no signs of water passing the new gasket so leading me to think either cracked head or porous block anyone had this problem????
