S2 using oil - looking for suggestions
 

Hi, have an '89 S2 & it's using quite a lot of oil - also seeing smoke out the back at high revs on full throttle (although seems more brown then blue?). It's had a top end rebuild, but at 246k miles I'd assumed rings may be getting a bit tired. However did a compression test over the weekend, and getting 200+ psi on each cylinder. Runs & pulls well, so hoping it's something relatively simple. Can OAS seals use that much oil? Also, I think I read somewhere that the S2 doesn't have the same problem with the oil cooler seals as it's an oil/air rather than oil/water cooler - is this right?
Any help much appreciated!

Thanks.

same oil cooler seals problem. it is an external cooler, but the tubing goes through the water passage.

what weight oil are you using? try a 40 or 50 weight. if you are using a 30 weight, that may be the problem.
