I've noticed that my plow truck, 83k20 powered by a weak-suck 350, has something going on in one hole.
you can hear it when it cranks over, that one hole is hitting differently than the others, and recently it blows blue smoke out the left tail pipe (true duals, with no crossover pipe) until it gets good and warm.
thinking it might have a gummed up set of rings in one hole. if you look in the oil fill you can tell that it hasn't necessarily been treated well it's whole life (the fact that it's on its second motor with just 100k on the clock is another sign).
so i added a can of seafoam to the oil. I was expecting that the oil would start turning black in fairly short order, but that has not been the case.
i've got about 6 hours worth of plowing on the oil with the seafoam (the oil was fresh otherwise), but it still appears to be as clean as the day i put it in --- which, it usually is even after a full year's worth of service.
even with the visible blue smoke, the oil level stays pretty constant. my last OCI was 2 years (maybe 500 miles) and it had only gone from the top of the full to the bottom of the full mark (which was the only reason i changed it, really. i figured why add a quart when i could just change it after 2 years of service)
typically, in the winter, if it starts, it is running for an hour or more while i plow. its a yard truck and doesn't go down the road, but the oil always gets up to 200+ degrees (via non contact on the oil pan) low rpm use, but a fair bit of throttle pushing snow (mostly because it's a 350 and doesn't have any power)
so .... how long before i start to see something happen?
