    Is this rod knock?

    That’s the plan, work on getting another 2F ready and just keep running this one. Leading theories on the noise are that the thrust washer on the cam shaft are itself, so now the cam is moving fore/aft, bouncing against the front or rear of the block. Or, one of the top bell housing bolts is...

    I did one more and it was horrible “accelerated wear” and so forth. In addition to the spare head that’s ready to go, I’m in the process of tearing down a 2F that I need to get to the machine shop. All things in time.

    10K trouble-free miles later … Noise still comes and goes, along with a worsening exhaust leak I can’t find, and very rough starts when it’s cold outside - lots of misfiring for about three minutes. Currently rebuilding a spare transfer case onto a spare H42. When I swap it in, I’m going to...

    Is this rod knock?

    I have a rebuilt head sitting on a shelf in my shop. I had it done a year and a half ago for a different FJ60 that I ended up selling. So at least I've got that.

    And yes, as soon as I get time I am pulling the oil pan. I'll have a new gasket, FIPG, and Plastigage on hand. Just haven't gotten the time yet and I'm driving the truck for now.

    Is this rod knock?

    Well, despite no glitter in my oil change a few weeks ago I got a Blackstone report back and it's not great. Looks like both coolant and a lot of wear metal in the oil. And no my oil change interval wasn't that long. I didn't send them oil in between and they're using my mileage from the last...

    Right ... but I still don't understand why the head would need to be machined to solve a wrist pin issue. Maybe he just meant "while you're in there you may as well do that too".

    Is this rod knock?

    Why would that necessitate taking the head to a machine shop? If it is a wrist pin, could I “get away with” pulling the piston, replacing the wrist pin, and putting it back in?

    Is this rod knock?

    Seems closest to the wrist pin noise to me. But my noise doesn't seem to get louder with rpms. If anything it seems like it gets quieter. Still won't have time to drop the oil pan for another 7-10 days.

    Is this rod knock?

    Did the noise change when you pushed the clutch pedal in? I honestly haven’t done anything yet. The truck was on jack stands for a week long knuckle job, and when I fired her up Wednesday the noise wasn’t there. Since then it’s been intermittent again, and low on volume. I got an oil pan gasket...

    Is this rod knock?

    Finally absconded with some time to dig in more. This is kind of crazy but the noise is loudest at the power steering pump. Granted, it’s kind of all over: right side of oil pan, block on the left side by cylinder 3, bellhousing, quite a bit in the clutch fork. I am not getting it in the valve...

    Is this rod knock?

    Correct on plug wires one by one and belts. No change for those tests. Really don't want to be dropping a transmission, but maybe that's my weekend.

    Is this rod knock?

    I’m going to dig in more tonight. Worst case scenario I order some parts and use the rebuilt H42 sitting on my shop floor to swap new stuff in. @RodrigzCrzr suggested that if I do that, to run the motor with the transmission out to potentially isolate the camshaft issue - or other engine issues...

    Is this rod knock?

    The C-clip makes sense. I assumed that’s under the cover plate on the front? My front main does leak … might be an w cause to go in there. But everything’s an excuse. Go in to replace a vacuum line and end up rebuilding the motor haha.

    Is this rod knock?

    @Zjohnsonua Also curious what would cause that scenario in an original motor. Just trying to wrap my head around it so I can be looking in the right places when I do some more diagnosis.

    Is this rod knock?

    this went way over my head because I’ve never torn an engine apart. You’re saying because the cam gear is loose on the shaft, the entire camshaft is bouncing fore and aft, repeatedly slamming into something behind it? When you say the gear is walking off the shaft when it loads up, you mean...

    Is this rod knock?

    Interesting. So the sound would be emanating from the lifters down below, or the valves up top? Devil's advocate question: why wouldn't I hear that more loudly directly at the source? Why is it loudest at the bellhousing?

    Is this rod knock?

    @fjc-man I set valve lash two weeks ago as part of the variable elimination process on this. Most were spot on and a couple were a touch wide, but overall nothing horrible. No mushrooming. The valvetrain looked good in action with the engine running. @BGarcia88FJ62 Last summer I had the side...

    Here is another video of the noise, this time underneath the truck with the flywheel inspection cover removed. Notice that when the phone mic gets adjacent to the edge of the bellhousing the sound increases in volume. When I used my homemade stethoscope I found that the sound was loudest through...

    @fjc-man thanks Bill, you're always a font of knowledge. I figured pulling that was a can-o-worms. I have a rebuilt H42 sitting here so maybe later this year I'll swap that in, and "while I'm in there" do the oil pan gasket, rear main bearing & seal, pilot bearing, clutch, and throwout bearing...
