Worn valve guides on a '89 3.2

[00BoxsterS]

My current car just got wrecked and am looking at a 1989 911 Silver Anniversary edition with about 100,000 miles on it. The owner says it burns about a quart of oil every 1000 miles and a mechanic said it needed valve guides. I'm getting a PPI done later this week but for a 100k mile 3.2 with worn valve guides, would a total engine build be a better option? Better to pass on the car? The car drove fine, no smoke but it felt a little gutless compared to my Boxster S.

All depend on cost and condition of the motor. At 1000mile per quart it doesn't need doing anytime soon. Leak down tests etc are what is needed.

Most likely it will also need rings at 100,000 miles. The Nikasil bores don't tend to wear. As has been noted, valve guides are the other common wear item at that mileage, most people would go for a top end rebuild, but if it was me I would spend the extra and check out the bottom end. Very unlikely to be worn, but new bearing shells and seals would be a wise investment. IMO. As has been said, check out impactbumpers.com

A quart in 1000 miles is no big deal on an aircooled

88s had a valve guide problem from new, the 89s not so much

I have seen top ends go to 180,000 or so and bottom ends go to 350,000

Rings at 100,000 miles? The car looks to be well maintained, 1989 911 3.2 anniversary edition. So a quart every 1000 miles isn't a big deal. The car drove nice, very tight steering but I was surprised it felt a little slow compared to my 2000 Boxster S but I should expect that from a 22 year old car.

Get a cylinder leakage test done, which will give a good indication of the state of the rings and valve seals.
