Uh Oh....

I'm worried I have engine problems.... :1zhelp:

I'm having lower oil pressure then normal these days... I also have a slight ticking sound from 2300+rpm when I give it medium throttle. BUT I think maybe it's an exhaust leak I hope?

We just tapped the downipe for 2 nipples and have them open but with a simple rubber hose connecting the 2 together. (I'm going to run -10an hose from the valve covers to these nipples for PCV and I'm getting my valve covers chromed now so this is why we jimmy rigged it for now).

Do you think that could cause the valve ticking sound? Why is my oil pressure seem lower?

Background info:

- Engine rebuilt 3000mi ago
- New oil pressure sender, new oil pump
- Engine seems strong? (Just dyno'd @ 380hp with only 12psi)
- There are 2 valves on the nipples that come with the PCV evacuation kit from Summit on the downpipe. These are just connected to eachother for now until with a rubber hose until I re-route the PCV.

I just got the damn thing idling good and resolved all my maft-pro issues and now I have a ticking sound Any idea what it could be????? Do you think it could be as simple as the nipples on the downpipe not being hooked up? Why is it my oil pressure seems low? It's full damn it! It shows 3/4 full on the dipstick.

Around what oil psi were you running before and what do you have now?

I don't have an aftermarket gauge, just the stocker. When I would start it up it would go to the half way point, maybe slightly more. Now it gets to about 1/3 when cold... and when cruising on the highway at 2500rpm, it's low, maybe an 1/8" off of 0. Normally it's about double that when cruising?

well damn, that oil pressure doesnt sound too normal to me. The rule of thumb is 10psi per 1000rpm, however idle pressure should be anywhere between 4 and 10ish. How many quarts of you do you use, I used 6quarts when i had my 7m. When you check your dipstick, swipe it on a clean paper towel and see if there is any metallic to the oil....if so then somethings wrong and you need to rebuild.

You could have a crank bearing going out. I've read on this forum that a good way to narrow down where the ticking is coming from, is to use a timing light and rev the engine 'till you hear the noise. If the ticking is in-sync with the light, its in the valvetrain. If the ticking is twice as fast as the light, its the crank. Although, this would probably not be easy to tell @2500rpms. Just a thought tho.
