Neither. Were it me, I'd try to find a lowish mileage used unit and replace with used. I am certainly no engine rebuilder, but I haven't heard much about honing cylinders to remove scoring. Most of the time when these engines are opened up for valve replacement, people comment that the original cyli...

I’ve got a decent short block up here. High miles but from a good runner

For a 1999 turbo you will need a pn engine with exhaust VVT to work with your ECU

Call me a red neck, but if it runs ok and looks ok, I can carry oil and put in oil every 1000 miles. At that consumption, it likely still does not embarrass you by smoking on acceleration.

This is waht I did when my 1998 S70 GLT with 190K had a burned valve #3 and trans losing reverse, I sold the car to a used car dealer for $300. I bought a nice 2004 V70 with 100K for $4200. On the long run, you are better off with a P2 car with 2.5T. Don't sink money into P80, especially when the od...

On reflection, I'd part it out. That's likely your best economic return, though it may take some time. The reason I would do so is threefold:. If you haven't already fixed the throttle body, you will need to do so eventually (XeModex rebuild runs close to $500), pretty soon there will be few buyers ...

My own, entirely unscientific suspicion with burned valves is that failing to replace front O2 sensor as a maintenance item at 100,000 miles is a contributor, as is low octane, generic gas use and overly extended oil change intervals. P.S. #5 valve is not usually the one to go. Generally #2 or 3. I ...

Do you run light (5000 miles per year) or heavy (20,000 per year)? It isqalmlst is almost always cost effective to repair a light running car vs buying a new set of problems. My gut feel is valve burning seem pretty rare and uncorrelated. Evans factors above definitely will put things in your favour...

I see you did a bunch of head work, did that include new valve stem seals? If not that could be another source of oil consumption. Also is a contributing factor to burnt valves. (a) run as is adding oil or (b) replace the engine. Don't put in one with badly leaking valve stem seals. Also swap over a...
