I'm in the middle of trying to figure out why my IDI makes this noise at idle. The exhaust noise seems to go away at higher RPM's and if the truck is idling cold, the noise is there but much less pronounced. (See video) The engine makes a ticking noise that appears to be coming from the passenger side head. The ticking sound is there at all RPM's, hot or cold.
I suspected it could be a lifter. or some other valvetrain problem. Injectors and IP were serviced by wes about 2000 miles ago. It didnt sound like a fuel issue to me either. I decided to tear the engine down and have a look. I have the valley pan out and the passenger side valve cover off. Appears to be more gunk and buildup towards the front of the head, indicating excess blow by from those valves.
I will get the driver's side valve cover off tomorrow.
Looking for opinions on what to do next. Spin it over, check compression and watch valve action? Just go ahead and pull the heads?
I'd like to fix it without pulling the heads but if they have to come off, I have plenty of time to do it. I could also just pull the engine, but I would have to borrow an engine hoist and get a helper.
Pics of passenger side head. One of the injectors was wet when I pulled it out.
