I'm in the market for a 914 and have a few under consideration. Something I'm wondering is, is there a rough estimate as to how many miles (or years) the engine will go before it's likely to need a major overhaul? I realize there will be lots of different experiences out there, but on average does it seem more reasonable to buy a car with a rebuilt engine (possibly w/ increased displacement) vs something that is relatively low miles but untouched?

I suppose the same question could be asked about the transmission...

So many things to consider in addition to rust! (IMG:style_emoticons/default/biggrin.gif)

if it leaks BAD, most likely it is coming from components attached to the engine:
oil cooler, oil pressure switch, push rod tubes, valve covers...
All these can be addressed with the engine in the car.

Front main seal is a little more of an issue, but still the motor isn't opened up.

I rebuild ("top end") when the smoke at start up tells me the valve guides are worn out. Piston/ rings/ crank etc ("bottem end"- kinda misnomer for a flat four) will go 200K miles with new oil every 2500 or 3k miles.

My car has over 400k miles, two full rebuilds with cyl head rebuilds in between over a 20 year period.
