Blue smoke should be because of burning oil (failure of valve seats?) and head gasket failure usually leads to white smoke (burning oil coolant). Only assumptions :)

guys,

I had a RX300, had the same thing. I thought it was Valve stem seals, paid a lot for the engine top done.

however, it turn out to be a PVC valve which only cost £1.20

change that 1st, then look at other things.

does anyone know the part number for the PCV valve :question: mechanics working for my local dealer are not familiar with this part... :huh:

I know it's a different car, but my mazda does the same... my mechanic says it's the valve seals

Sorry for replying so late. I've replaced the PCV valve (Part number 12204-70020) and a grommet (part no 90480-18001) which holds it as my old one cracked during removal (I'd recommend to order one before you perform any checks on valve). I did follow the manual instructions and my old valve was faulty! And it was all covered in oil. Unfortunately it didn't sort out the problem and i still get the blue smoke on cold starts :( there's no other problems, engine seems to run very smooth and strong (for 150bhp ;) ).

So it seems to be the valve seals after all :( but i'm going to leave it as it is for now. Thanks for help everyone :)
