    It's not mine - just pics from a car-breakers website!

    Did you notice, the PCV hoses, into and out of the cylindrical oil separator, are well insulated, to keep the gases hot? A lot of folk who are installing catch-cans are collecting a lot more condensed water than they are oil. I much rather have pure water vapour going into the inlet tract than dirty water, once it has been condensed and accumulated to a level where it might get sucked straight into the cylinders. Vapour is at least compressible....

    Another view of the front of the engine - with inlet manifold and water pump removed. Unfortunately, it's not at all clear where the oil is returned to the sump by the PCV oil separator. A possibility is marked ??

    Come to think of it - I may be quite wrong... Maybe there is no return to the sump, but the 'separator canister' is heated by engine coolant!! Too hard to see for sure without taking things to bits... maybe it's not even a separator - could be just a heat exchanger to warm up the gases coming from the PCV valve??

    Thanks for those, interesting. The EGR location looks easier to get at, once the cowl is off I'd assume.

    Very easy - The only thing you need to remove, for access, is the push-on grey plastic engine cover, which just pulls off!

    Is it just me, or is that cover on back to front? Strange, that Toyota text is upside down.
