Well today i went out to change my fuel filter, everything went good, start the car seems to be doing good just letting it idle (cuz i have no insurance lol). I go to rev it up and it hesitats untill 2000 rpms.......any wayz moving on i get out of the car mind hood already open i hear what seems to sounds like a tapping or knocking but cant really make it out going to change out plugs wires cap and rotor and see where that get me with that. next i turn off the motor and hear what seems to be like asucking nosie it sounds like it is coming from where the coolant lines go underthe plenum. next (lol) when i first start the car oil press is 60-65 then after about 5-10 mins of running(idleing) it dropd down to 20-25, but dose gose up anywhere from 40-and up wen i hit the gas... just making sure everything is good with my car. hope that all these problems are coming from the just sitting around... thanks alot guys for the help....

when a car warms up, a drop in pressure is normal, oil thins out as it heats up and oil pump is driven my dizzy, which is driven by cam and is rpm dependant, so of course as you rev it oil pressure goes up, you are fine with the pressures listed

The tapping noise could indicate a header leak, the sucking noise sounds like a vacuum leak, could be the PCV valve has popped out of the back of the manifold.

thanks guys i was just checking on the oil press to make sure it was right and everything was ok.....i am going to check the PVC today and hopefully that fixs that and i am in the process of replaceing the header bolts so that could be it i didnt even think of that thanks.. will post with results

Not to hijack this thread but what is the EEC? My green vacuum line was disconnected when I bought my notch and I have been trying to figure out where it goes.

Green line goes to the EGR valve, the one from the EVR.... the three lines you see under the EVP, are the EGR Valve Position sensor connector wires, not vacuum lines. EEC = Electronic Engine Control module, also known as the ECM (Engine Control Module)
