Oh, please let it just be a bent push rod.

Post by Brent Borgaard » Sun Sep 19, 2010 9:20 pm

Driving home last night. The bitch was running like a dream. Out of the blue, dropped a cylinders. I guess that`s how you spell it. Drove it up to my brothers house today. No noise, no rapping. Put a temp. meter on the header tubes. 430 degrees on all , but #5 at 200. Did a compression test. 50 lbs. The only thing i can think of is, my rocker stud backed out or i may have bent a push rod. Not allowing enough draw on my intake stroke, to build compression. I`m hoping for an angry dwarf.

I`m at about 15K miles on the motor. I`m hoping for a collapsed lifter or a bent push rod. If not my intake rocker stud backed out. That`s the only other thing i can think of , giving me a low compression, besides my rings. But there`s no blow by. I don`t think i`m getting enough valve opening for the volume needed for combustion.

The spark plug failed. My brothers compression gauge is messed up. We tried another cylinder and got the same reading. Thank God.

You should put the compression gauge up your brother :ANAL: ! :twisted: See what reading he gets. (For giving you bad info) :lol:

Glad to hear it was something easy for once. I started hearing something in my motor last weekend when I had that issue on 695 and I thought a rocker arm or push rod had or was going soon. after some research and check out all those goofy you tube videos I found out that I had a stuck injector that was making the noise. Its not going to kill anything and it will run just a little sluggish sometimes. But now I need to try and figure out which one it is by sound so I think its the passenger side and that means the manifold needs to come off (!@%%#@). Pyro meter install would be a easier though.

Just start cracking injector lines loose, one at a time and see which one does`nt make a difference while idling. Easiest way to check diesels.

Do you have on of those point and shoot temp. gauges? They work great on the exhaust manifold, to find a dead cylinder.
