I picked up a 253 genset that ate a valve. Got it all rebuilt and running but I have no idea what the oil capacity is. It looks like the dipstick is broke off and someone took a grinder to it. There are no marks on it. Best I have found is 9 quarts in a 353. It’s got 8 quarts in it now to get it going. Do any of you know? I have a service manual for it but it doesn’t say any capacities.
