I just disassembled my 99SRX engine and split the case. the cause for the teardown was a burndown on the Mag cylinder which will need a new piston, rings etc at minimum. I also am hearing a good rattle from the mag side crank bearing which I expect is from piston material working into the rollers. When I look at the three pistons they appear progressively better as I move away from the mag side, the center is showing a little wear that is really just superficial, and the pto piston looks pristine. I think thisis due to a lack of lubrication, but I don't know why. There is oil in the reservoir and it appears the oil pump is working because my pto piston looks great, but it's clear the center and mag were getting less lubrication, or seeing higher temps. Does this sound like too little oil, Or loss of coolant? Alsonis there a way to troubleshoot for either of these causes? Just like to know why it happened before I invest time& $$ into a rebuild just to have it happen a second time.
Thanks
