did a leakdown test on a 351 crate motor, using 60#'s, and all were reading in the 54-56 range, except one. it read 50#'s.
my question, would a difference of 4-5#'s indicate a blown headgasket, cyl #6 by the way? i've experienced this before but the difference was quite a bit more.
i have a seep on drivers side between block and head, what i thought was at the rear, but could be #6 and running back on the crack.
cooling system built enough pressure to blow hose off radiator, although hose could have been loose, and there is no h2o in the
oil upon draining.
so what do you think? tear the head off, or go with it?
i had attempted to run bars leak but the regurgitation was quicker then the seal.
none of the plugs looked worse for the wear, and you couldn't pick out #6 if you had to.
