I own a 94 GSR with basic bolt-ons (I/H/E), and recently have been experiencing heavy oil consumption (about 3/4 of quart after 600-700 miles), but with no power loss. There are no oil leaks anywhere on or underneath the engine, and there is no colored smoke for the most part unless I really get on it (then I sometimes get small puffs of blackish gray smoke). My car has about 90000 miles on it, and gets serviced regularly. Any ideas on this prob? Any help would be greatly appreciated.

 

Sound's like rings or valve seals to me. I reccomend you get a small loan and rebuild. If you choose the right combo of part's (Skunk2 manifold, ITR cams and piston's) you will get excellent power and honda reliability. Make sure you search around for an excellent machine shop/rebuilder bfore jumping into the project
