I get some engine noise when I dont let her warm up from time to time. It goes away pretty quick.

Hey, have you looked at the harmonic balancer lately? Many a fellow here have told tales of great sadness when that thing goes out of whack and it can be an engine-killer for sure.

On my second year of CUCV ownership and up here in the high desert it gets plenty cold, like in the low 20's. When starting my 1008 it makes various sounds for the first few minutes but then settles down to a low rumble. One thing it does, hot or cold, is at idle the air cleaner assembly sets up a vibration that could double for a tuba. When I open hood and press down hard on the housing it stops. Haven't figured out how to get rid of that noise yet... anybody else?

Benny hill knows all!

He may not know it all but he could make people laugh.

Ok all...Thanks for the feedback. I did do a fresh oil change a couple of weeks ago and I use Mobil Delvac 1300 Super 15w-40. Oil level is good but after a couple of hundred miles it sure is dirty all ready.

I will probably do an engine clean with Auto-RX. This stuff come very highly recommended and I'm thinking about giving it a try.

I also just started running Jet A in the truck and we'll see how that goes.... I add Pri-D treatment to it and I add 4oz. of 2cycle Marine Oil TC-W3 spec to every 5 gallons and the truck seems to run real nice on it. We have so much surplus of it that I already have 60 gallons of it stored as well and the price....Free......Love it.

Could it be a flat lifter, drained of oil over night and needs to pump back up? I've heard some engines, not the CUCV diesel that made some serious tapping/clanging noise on a flat lifter until it pumped up with oil.

could be a sticky injector mine was doing that fixed with new injectors!

You sure it isn't just your glow plug relay cycling on and off?

This noise is forward of the firewall? Below your feet? or Behind your dash?

That's any diesel dirty as soon as you run it again. Not like gas engines for sure.

I have a clank/buzzing noise, and its my GP relay when cycling off for the final time... Not sure what it could be seeing as I have a new card, and relay, ground issue maybe? When it makes the noise, the water in fuel light flickers, but its a LED now...
