I've enjoyed over 200,000 nearly trouble-free miles in a similar vanagon. I don't know what he's doing to get it to 300,000, but I'd like to. But what about the alternative... rebuilding what I've got? Sometimes in the next 50K miles, I think it would be prudent to pull the engine and install new bearings and seals, etc. The engine burns NO oil between changes. If the pistons spec out right, does that mean that I could score up the cylinders I have and install a set of rings? The original crosshatching is clearly visible in my cylinders. If there's nothing wrong with the heads to speak of, would it make sense to press in new guides, replacing valves as necessary, and go with that? Of course I would replace lifters, seals, water and oil pumps, etc. But if the engine is in good shape, is it considered that a fairly light overhaul will do the job, or is it new stuff from the block out?
