Just installed s14 sr and got it running but has compresson across the board at 120. I need to know if that is blown head gasket compression. It smokes like hell so im sure its burning coolent I just want to make sure its not something else. It runs pretty good for the low compression it has, revs up perfect and everything. Such a bummer I bought an sr with a blown head gasket

well the Compression Ratio is : 8.5:1.

dont know if that helps but at least nothing else is wrong with the engine. not that hard to replace. still sucks though.

Im not tripping out if its the head gasket or anything, ill buy the metal gasket and install it and everything no complaints. I just want to make sure it is only the headgasket before I go that deep into the engine. I just want to know from anyone who has blown a head gasket what their compression was, to see if mine is similar. My car burns coolant like a batch, after running it for five mins radiator was 3/4 full after completly filling it and bleeding all the air out.
