I have a classic 95 WRX Import.There is grey smoke coming out of the engine breathers and also smoke coming out of the dump valves aswell as blue smoke from the exhaust.Any ideas what could be up ? Possibly rings ?

Thanks

 

If it started happening all of a sudden, most likely ring land(s) rather than the rings themselves, although broken lands, if left uncorrected, will result in the rings being compromised so the end result is the same.

Valve stem seals might be a factor (although much less likely). Only way to know for sure is to compression test, and ultimately strip. Bad luck.
