Absolutely brilliant. Even though I've done this job many times, I found the information invaluable if only to tell me that I do it the way others do. Interesting reference to spare engine......... yes I've got one too. Again, I've argued in favour of re-sleeving the bores to standard. If you're buying pistons anyway the only difference is between the cost of a rebore and a re-sleeve. The Snap On thread cleaning set is what I've tried to point people towards rather than using taps which end up enlarging the thread. Can't wait for the next episode.

Thank you. Another amazing contribution.
This engine is getting rare, if we want original jeeps, we need to rebuild them.

Nice tutorial! Your right, a well maintained engine should get 250-300,000 miles to it. With the new chemistry in oil these days, a engine should be able to retire at those kind of numbers. I drive truck on the side, and have seen those desiels push to 3 million miles on them, every thing else dies before the engine calfs. Ihave rebuild a few engines in my time and its always nice to see somebody spend the time to show those who haven't, its not as scary as it may seem.

Thank you so much. Not only for your expertise, but fore the time and effort you have put into making this invaluable information available without the drama of "this here is my bestselling book".

Your talents and your gift to people trying to get a piece of history back on the road will inspire and help more than anyone can imagine. Best wishes.
