    Hey guys. It's smoking a bit after over run, ie cruise for a while, then boot it and it someone's puts out smoke. Should I change from 10 40 to 20 50 on a standard tt?

    Maybe do a compression check, check your breathers and run a catch tank or perhaps your turbo seals are blown. Hope that helps

    Breathers, the PCV valve in the intake cam cover but ultimately it sounds like valve stem seals and the weight of oil wont really help.
    Try heavier oil if you want.

    Cheers guys. Swampy, is the pcv valve the thing that comes out the side of the intake cam cover? Also, I bought a new breather pipe to replace this one.. [​IMG]
    As it don't look good. If breathers are blocked, does this cause higher pressure which then gets passed seals? There's no smoke on startup, hence I'm thinking it getting passed turbo seals.
    Worst case scenario, how long would it roughly take me to take off the turbos for recon

    No its the other side, pretty much directly opposite that breather pipe.

    Cheers mate Ye I'll get that from Toyota next week. My mate said put a one way valve in the pipe pictured above as well. I've now put my new pipe on btw
