blue smoke only when engine is hot?
Hi all got a smokey 2.0 ts but only when hot.
Full engine rebuild some 1000 kms ago.Piston rings also changed.
now after the rebuild it still burns a lot of oil: 0.5 l for every 300 kms of 3500 rpm cruising.
It only recently started puffing clouds of blue smoke when engine is hot.
The breathers are vented into a can for now (to help diagnose) and the manifold is plugged where the breathers were connected.
If this is a rings issue shouldn't i get blue smoke also at cold startup when rings don't seal that well?
The can where breathers are vented accumulates some 100mg per 100km of city driving
I am starting to think that this might be a partiallu blocked exhausy issue as the cat is a universal Bosal and has haf maybe some 20 ltrs of oil go through it during the last 2 yeats?
