good morning Malvo my name is ***** ***** to hear about the blow by. assuming that you are not using coolant it sounds like its time for an inframe rebuild. Basicly your building excessive crank case pressure from compression sneaking past the piston rings. this can be caused by valves that are tired or worn piston rings. If you didnt want to spend the money on an inframe kit I would get the head rebuilt and see if that helps. either way, if you do a rebuild or not the head should be done
just a word of advise on the piston sleeve kit..... there were a ton of variations on this engine and piston height veried from one engine to another. be very careful if you order after market pistons. my suggestion is to get the OEM part #s and have aftermarket match them up that way.
hope this helps and thanks for using JA
hard to say how long it will last...week...5 years....tomorrow
run a good quality 15w/40 oil such as shell rotella to help keep it going. as far as an additive.... not really sure what works better than the rest. I personally feel that additives only mask issues and make it difficult to see just exactly what you have.
good afternoon Malvo, you all set on this? if so when you have a second rate the service and I can close this out. have a great weekend ahead
