negative boost and low oil pressure

[fubar_mdw]

well i fixed the problem i had with the knock in my car
http://www.dsmtuners.com/forums/newbie-forum/283099-some-knocking-head.html
that was the forum
it was i believe a bad leak from the intake manifold gasket.
now i have very low oil pressure (stock oil pressure gauge)
the lifters tick very slightly when the motor is cold,
and my boost gauge (greddy) sits on -15 on the guage at idle and goes even more
negative when i give it gas,
i went through all the vaccum lines (emissions deleted)
and egr blocked off.
cant find any leaks what so ever and there is no oil leaks either
the timing is dead on and the base timing is set at back 5tdc.

at idle you should have between 17-22 in/hg which is negative on a boost gauge and as far as the oil pressure the chilton show oil pressure @ curb idle speed to be 11.4psi @ 167-194* F so if the engine is warm the oil gauge will look like its on the low side

both the vac # and oil pressure #'s came from my chilton so if that helps any shows the vac a little low so you may have a small boost/vac leak still

ya i did alot of reading on other sites and stuff and it seems
like my boost is normal i havnt drove it yet to see if it boosts where i want it to
but the oil pressure is from the stock one i havnt put in a good one yet
so it could just be the gauge, however before i tore it apart this morning the guage read fine
now it reads low

just ordered a oil pressure gauge,
wont drive the car until i get that installed to make
sure all is well

just got the oil pressure gauge about to go install and see what happens
