Found my noise and air leak

Well part of the gasket is missing where I took off the old fuel filter canister when I put on the air dog. It is about as long as the distance between both bolts. Anybody know what that gasket is called and where I can get it? It is the gasket that seals I believe the manifold under the injection lines and pre heater. I sealed it down with the bolt and washer set up the best I could but it is still pushing air. At least I cant hear it in the cab anymore. Will it hurt driving it since it is pushing air and not sucking it? Other than the power loss.

No boost at an idle. Go to Cummins and do it right. VERY cheap insurance. A dusted engine is a VERY bad thing.

I am kind of confused by what you mean. It is a simple gasket replacement. A leak like that though, will basically give me no boost at idle though?

Unless you install a VG turbo, there is never any boost at idle.

If the gasket is blown out, Get it fixed it is not a big thing or do it your self, get it clean, and while you are at it, do the valve set. If you tighten the bolts you can distort the cover, you want to file the cover flat when it is off. And if you leave it you will dust the motor, at Idle they do draw a vacuum, and when you first step on the throttle also. You will need two intake horn gaskets , and the intake gasket. if you do the set you will need the seals for the hold down bolts take your CPL when you order parts. the torque is 18 lbs

Thanks alot, ya I misplaced my manual so I couldn't think of the name of were the gasket was. By dust the motor I assume you mean blow it up? Or just destroy it? Basically one and the same. Also it has been making this noise since early summer and I couldnt find the noise. I took it to a diesel shop and they couldnt find it either. I didn't see it until I guess part of the gasket disengrated. Ahhh... I should have checked their anyways. So basically what damage might I have done? And should I stop driving it right away, which would kind of put me in a bind. Or just go ahead order it and, replace when I get it.

You can only fix it when you can and clean out the intake, what is done is done, dirt is a very bad thing in a diesel. Play safe!

Haha, I thought Diesels loved dirt? Hopefully I will be ok, cus feeling it the air was pushing out rather than causing a vacuum effect (at least seemed to be). I put a piece of ceram wrap against where the gasket was missing and it pushed it out rather than sucking it. I ordered the intake gasket from auto zone, and got my other gaskets from Geno's. Thanks for the help.
