I have a 05 rev up with crazy high oil consumption problems 71k miles. Cylinder 4 is where the problem is. The spark plug is badly fouled up on the tip and theres oil on the bottom. On first start up it smokes a lot of white smoke, then it calms down, only smoking when i rev it up, after a few revs the smoke isnt as bad. No loss in power, havent done a compression test yet, what do you guys think, valve seals or piston rings.

You should do a leak down check.

My bet, seals , but could be either.

If it is the seals, should i only replace the valve stem seals or other things too while im at it

You're looking in the 20 hour range for the seals. At 71k you may want to think about a rebuild/upgrade, do a full compression and leakdown test.

Compression or leak down test.

Also make sure the p-rings gaps are not aligned. They should all be staggered.
