So when removing the oil jets, do you just let them be have the bolt hole open, or do are you supposed to screw a bolt in. Sorry for the silly question, I'm just trying to do it right. Thanks
You have to plug the holes with 10x1.25 10 mm plugs.
Otherwise you'll have a very short lived engine - no oil pressure, fried bearings, mayhem...
Engine is out and disassembled, AND things look a bit grim at the moment.
Bearings are bad. #4 rod bearing has flaked.
The engine had a bad miss on #4 for a little while due to a collapsed valve seat.
Everything in the head has been replaced since, but the damage is done I guess.
#1 cylinder wall is scored.
Pistons have scratched skirts.
Crank needs polishing.
And yes, oil control rings were pretty much gummed.
I've heard....but not seen first hand that a flaked and pitted bearing like that is the result of detonation hammering them. The other bearings are more indicative of trash flowing through the engine (most likely from the flaked bearing) I would very closely inspect the #4 piston for signs of detonation. The collapsed valve seat is another indicator of that cylinder being hot from detonation. I see that you're running a coolant reroute, normally not running one is why you only see this issues like this on #4, the back cylinder runs hotter due to lack of flow and is the first to detonate when running on the ragged edge. In your case maybe it's a lower flowing injector or just dumb luck that it's #4 this showed up on.
You want to find out how much it would be to import one? I have two block sitting here and you can have one for the shipping and import duty, land freight could not be that much...
