Here's the scoop. I'm talking about this for two reasons: One, so people can learn from my mistake. Two, I could use a little advise on how detrimental this mistake MAY be and comments about the solution.



I was having a problem with my intake manifold gasket. I was not getting the boost I was in the past so checked out a few things and I believe when I changed over to a FASS and removed my fuel filter, the bolts that hold it on have no threads on the top. Hence the tourque that I put on the bolts to tighten it - didn't because I bottomed out the threads. Pulled off the cover and found the gasket was leaking. I also found the cover itself had small little heat cracks on it from expansion and contraction. Well a quick call to Cummins and found that a replacement Air Intake cover is $17. 95. WOW Thats a no brainer. Got a new cover ordered and had it shipped. A quick call to Haisley and ordered up one of their new aluminum air intake gaskets to replace the stock one.



In the meantime I had stuffed the intake with Rags to keep any mice or anything from crawling in there. Little did I know, they got through it and I found my intake area filled with about 20 nuts when I went to put on the new cover. After a few explitives and sensing fear that I would have to pull the whole head to get them all out. I contacted CPFF and he suggested pulling off the exhaust manifold and blow air through that exhaust side to blow any thing that may be in the intake that may be by the valves. I will also have to bump the motor to open some valves that may be closed to get all of them clear. As it stands right now all visible nuts are gone with the exception of cylinder six in the back. I had to pull off most of the fuel lines to access it with a vacuum and cant get that far in to pull them out but I'm still working on it. I believe there's only a couple left back there.



I'm dreading pulling off the exhaust manifold. Any helpful hints on removal?

Think this idea will work?



Feedback is appreciated.

why not shop vac each port for a few seconds to insure anything down there is out.



in my opinion Nuts wouldnt hurt much if you just kill the fuel and cranked the engine over to crush them and let it go at that. I know everybody will jump on me about Oh the turbo! well no faster than it turns while just cranking you aint gonna hurt it. trust me!
 
I'm with Todd. I'd probably just crank it over and let the engine chew them up and spit them out.



You could also use a shop-vac set to blow backward through the exhaust. That might help.

It's not the turbo I'm worried about, It's the valves. These nuts are about the diameter of a nickel.



But you guys are calming me down a bit more. I may not pull the exhaust manifold after all. Maybe just the turbo and send some air through where the turbo meets the manifold.



Hohn, It's a 5 inch exhaust. That may take alot of Duct tape :-laf
 
let it eat! LOL



if they are that large they wouldnt fit through the valve opening. its really not that big of a deal. clean it out the best you can, get all prayed up and fire it. it'll be fine.
 
LOL,, I thought "Nuts" was your expression to your problem.



I thought a broken bolt, or melted grid heaters,, I wasn't expecting to read of actual nuts in your intake. LOL



(I had a funny pun, but I thought the TDR admin might not like it's references :-laf )

mac, sorry to hear of your troubles :( when you get a chance would you please post the cummins parts number for the manifold.



Thanks
 
No problem Bob, I'll get it when I get home. (workin)



I had that cover coated by Airborn coatings in East Hartford, CT. (About 15 minutes from me) Good guys. The new cover painted red will look slick when I get all the nuts out. :rolleyes:

I also had the airhorn and the cylinder head bracket for the APPS done in the red. I also had my Entire Denver Offroad bumper refinished by them in metallic silver.

I just couldn't believe the price from cummins for that intake cover. DC probably charges $100. ;)



I'll post a pic when done.
 
I know it is irrelevant to you at this stage; but you can prevent mice and other critters getting into such places by stuffing them with steel wool.
 
Man you need a cat!



I would not recommend cranking them through because it could cause some expensive damage. Just imagine a piece of nut keeping a valve from closing resulting in a piston contact. The result could be a broken or bent valve and or damaged piston. Not worth it IMHO.



If it were mine, first I would shoot my cat for failure to perform his appointed duty. Then I would pull the intake and use a shop-vac with the appropriate hoses, to remove all traces of the nuts. Yeah, it's a PIA, but its less of a PIA than repairing a damaged cylinder. Remember, nuts aren't compressible. Don't believe me? Just try compressing your own... :--)

I would avoid turning it over intill your sure that all the nuts are gone I would be worried about a valve it's amazing what can mess up a valve. the shop vac sounds like a good idea or i would be trying to find a bore scope so you can take a good look.
 
Kevin, It sounds like you are really stressed about this. It's not a good thing to stress out. So I tell ya what, I'll remove all of the stress for ya... I"ll buy the truck from you for a hundred bucks. See, all stress is gone for you, and I'll deal with the nuts.
 
Bob,

Part # for the Intake air cover is Cummins #3941437



Not done yet with the nuts. Spent half a day yesterday trying to get them all out. My biggest problem is by cylinder #6 WAY in the back. No real access and the nuts want to stay. I have removed the IAT sensor to blow air through to dislodge them. Still workin on it.
