Pretty straightforward question, I picked up a genset with that engine on it, it ate a valve and I just got it all rebuilt and running but I'm not sure on the oil capacity. Looks like the dipstick is broke off as there are no marks on it and it looks like someone had taken a grinder to it. Closest I've found is 9 quarts in a 3 53. I put 8 in it to get it going but I have no idea whats supposed to be in it and finding a new dipstick for it is practically impossible. Not a lot of the little engines around. Anyone know? I have a service manual for it but it doesnt have capacity info in it.
