: True about cold oil pressures though -
: that 80 psi cold idle shown translated
: into about 5 psi hot idle with knocking

: If the engine is out - drop the sump.

: If you can't do leak-down try a wet

: with the dry one you already did.

: True on the cold OP. It's been a few
: years (decades?) since I last saw a
: live reading, but I did have a gauge in
: the car and believe the cold OP was
: around 80/90 psi at about 2K rpm.

: That sound reasonable Doug?

: I would be a bit concerned on that
: compression spread from 145 to 175 PSI.
: That's about 9% up and down from the
: average of 161. Being anal I'd do a
: leak down test to identify if there is
: anything to worry about regarding the
: number spread.
:
: If you do crank the engine over on the
: starter to get oil pressure it will be
: cold pressure which will be higher than
: hot idle. It may give you a false
: sense of security.
:
: Were this mine, in addition to the leak
: down test I would at least drop the pan
: on the engine to check the bearings
: with Plastigauge, fit new front and
: rear seals, and I would consider
: replacing the oil pump if you don't
: know how many miles are on it. While
: all these things can be done with the
: engine in the car it will be a lot
: easier before installation.

: I have a GT6+ Engine and Tranny that I

: What things can I check on the Engine
: and Tranny to make sure they are in
: good nick, before install them in the
: Spit.
: compression readings from #1 Aft,
: 145,175,165,155,155,170 .
: Tranny: 4 Speed No OD.
