situation with a 1979 international harvester( 345 cid engine)?
just got the truck running last month for the first time on, well since i have known the owner ( 9-10 years). now it has a miss ans what sounds like a rod knock. he replaced the connecting rod bearings and main bearings twice, plasi-guaged them in between
A mechanic's stethoscope will help find where the knock is. I would listen closely around the cylinder that is misfiring, and around the oil pan. You may need to remove the valve cover and check the clearance. They are not adjustable. If you think it
