Bro-in-law's 208 started puffing out blue/white smoke so it just went in for a compression test - 280-300 for each pot but should be 400. It sounds like general wear but until last week it was running perfectly and always has done - no smoke at all, even on full chuff.
Any ideas what else it might be? It's blowing through the oil filler cap too so I suggested valve seals to the mechanic but he thought not.
It's billowing out smoke now - LOTS of it, and using plenty of oil.

p.s. Also, one of the tappets has got very noisy over the last few weeks.
