Hey everyone I got a question for you guys because I just can't figure this one out.
Ever since I have owned my truck, I have had this intermittent ticking sound that the engine makes when it is hot. It doesn't seem to be consistent with every revolution of the cylinders and it is not an injector knock(maybe a tick every couple seconds). I have noticed this sound doesn't seem to be evident when engine is cold either. Treatments of seafoam in filter and other mystery liquids have no effect on noise. I also do not notice any loping and/or miss that is common with bad valves or injectors. Also, I only hear noise when engine is idling. When the rpm's go up, noise goes away.
The truck has new pop tested injectors, 65k on rebuilt IP, new glowplugs, etc. I try and keep up with the maintenance on my rig.
So this is what I am curious about. Is this just a typical carbon buildup situation that is common with these idi's? Because when I pull hills and keep the foot to the floor for an extended period of time, the noise seems to go away for a week or two....then returns. I also maintain oil changes and am currently running my first treatment of Auto-RX, because I have the typical high volume of blowby and lots of oil in the intake...even with new cdr. So far, the RX has reduced consumption and blowby drastically.....just curious about this ticking noise. I am thinking there are a few stuck ring packs which is why I am doing treatments. Thanks in advance guys!
