    did a compression test the other day because my leak down tested was broken (did it cold didn't wanna burn hands), all cylinders read within 5% of each other except #4 was zero, time to get this thing up on ramp and get the power tools out.

    The guy i bought it from got it from the org. owner and he had it 2-3yrs but didn't drive it much cause he could not get it to run right, i'm thinking some backyard mec. thought it had a vac. leak and pulled the intake.. blind leading the blind.

    I would pull it. Easier to work, do other things like rear main, timing chain etc. Not to mention clean everything.

    If you have a lift I would drop the trans then pull the motor. That's what I did. You will need a arm extension on your engine puller because of the of the nose of the ta. Going at angle helps too depending on the engine puller u have

    I owned 308 after Robert...barely drove it but never had any issues. Ran good as a matter of fact.

    Does it still have a aftermarket boost gauge? You also need to prime the Alky every time you start it but that shouldn't matter at 15psi and it looks like a sudden bang, make sure the gauge you have is accurate... how many miles on it now?
