So I’ve been driving the truck to work the last couple days. At 100 miles a day you start paying attention to all the noises and rattles. For a little while I’ve noticed what I’ll call a tick that seems to reside on the pass side of the engine. It’s definitely engine related. Tracks with rpm. It gets really noticeable when you step on it. Honestly, I’ve been thinking exhaust leak. I took a quick look (certainly not exhaustive... pun intended) and I don’t see an obvious soot trail anywhere. The other things that jump to mind are valve train given the history of this engine. I also wonder about an injector. If you come gently up through the rpm range it’s not really noticeable but if you stab the fuel it makes a fair bit of noise. I need to try to video it but I doubt you’d actually be able to hear much.
So all that said, I know asking to diagnose a noise you haven’t heard is a pretty silly rookie mistake so I really don’t expect a diagnosis. I’m looking to work through troubleshooting to make sure I’m not missing anything or overthinking something. So I’ll ask a series of questions.
1. Would a weak injector popping early cause a tick type noise?
2. How often would you guys pop your injectors. I figure I’ve got about 10k miles on these that were new stanadynes from Russ.
3. I’m thinking I may need to pull the pass valve cover to look for evidence of blowby the valve guides. Could a bad guide cause a tick like noise? I know we describe chuffs and huffs. I just don’t know what that would sound like where the turbo is involved. NA it seems pretty easy to hear.
4. Could it be trying to push a head gasket that only makes a sound when under load? I haven’t checked the radiator for bubbles yet.
5. Aside from the soot trails, any suggestions for finding exhaust leaks?
6. Anything else I’m forgetting to check?
