What is the average lifespan or lifespan you've experienced on the engine of a 1969 VW Bus?

Curious as to what I can expect if I make this purchase.What is the average lifespan or lifespan you've experienced on the engine of a 1969 VW Bus?as with any engine not just air cooled, old, VW engines, there are many factors that make it impossible to know how the engine was treated before you owned the bus.



with that said expect to get about 80,000-150,000 miles before needing a rebuild. its VERY VERY VERY VERY VERY important to keep up on the regular maintenance with these engines. if not you'll be looking at a rebuild every 5,000 milesWhat is the average lifespan or lifespan you've experienced on the engine of a 1969 VW Bus?They go bad frequently because they are air cooled and have to be driven at full throttle often, not to mention they are now 42 years old.What is the average lifespan or lifespan you've experienced on the engine of a 1969 VW Bus?Orginal owner, regular maintance,new factory motor pray for 75,000
