Well after a bit of a break here’s where I’m at. Pulled the oil pan and all the rod caps. Crank looks fantastic and measured great with standard bearings, though they weren’t oem so someone has been in here before. Did find some weirdness on the rod bearings and the #1 rod cap had a chunk of...
I always tighten them more than remflex says. I’ve used them on half a dozen SBC’s, a couple big blocks, ford v8’s and 5-6 F/2F engines and have never had one leak yet.
Before I pull the pan I’ll remove the belt and run it checking manifold to head. It’s a brand new remflex gasket and I’ve yet to have one leak but never know.
I don’t think it’s heat related as it does it hot or cold and has since the initial startup. Also has completely flushed cooling system, new water pump, radiator and fan clutch, thermostat verified working in varying degrees of water.
Thinner oil could be a culprit, but I don’t see the...
Pulling plug wires 2 at a time made no difference.
I used my camera scope in each cylinder and they all look fine and no chunks in there.
Compression test all 130-140.
Spun it over with no plugs in and no noise: can only hear it when it’s running idle to 1500-2000 ish rpm.
My wife picked up...
I’ll try pulling 2 at a time and see if it makes a difference. Trying a real stethoscope tonight then will likely be dropping the pan to do some rod wiggling (hehe).
Had the same noise but also an odd noise that sounded like an exhaust leak in the manifold. Investigation found low compression in 1 cylinder and ended up being burnt exhaust valve and cracked combustion chamber/ valve seat.
Before any of that, had the engine out to clean, reseal and paint...
Oil pressure is great, over half the gauge at idle and 3/4 while driving at 2000 rpm and up.
Oil is 10w-40 PennGrade. This is the oil he uses in all his other classic cars so keeping it the same.
There’s plenty of oil in the top end. It runs out of each rocker as I expect (same as about every...
79 FJ40 with stock 2F. Just replaced the head. Have a deep knock/tick sound. Can hear it well at idle but gets fainter as rpm’s increase until you can’t hear it at all anymore at maybe 2000 rpm. The engine runs fantastic, super smooth, tons of power, no smoke. I do not believe this to be a rod...
