Re: [Amc-list] recently rebuilt 343 - No Oil Pressure

Well, there are not only those 2 plugs under the intake, but also 2 in
the front of the engine under the cam gear area.   Are those also
missing??

Hmm, no engine builers replied... OK, I'm rank amateur engine builder,
but... that sounds bad to me. The first few minutes are the most
critical by far.

Usual practice is to spin up the oil pump with a drill and flattened rod
until you see oil pressure, BEFORE you fire up... or at least spin it up
until it "gets stiff" so that the galleries are all full of oil and the
pump primed.

No way you wanna hear this... if it were me, I'd pull the engine now,
with the assumption that if you don't, you will later, with ruined hard
parts. Or see if you can get the pan off and pop a bearing cap or two. I
dunno though, cam lube is dead critical at start up. Did you use
high-zinc lube on everything at assembly?

Sorry, I think no one wants to say anything so depressing. Maybe the
more-optimistic will slap me down here. I do tend to be on the paranoid
side when it comes to assembly.

Thought I would ask the experts before I pull the intake and have to buy
a new gasket.
