    Hi members, I’m new in this forum.
    My 2003 Toyota Echo/Vitz with 1SZFE 1.0 litre engine was leaking oil from the timing cover gasket near the water pump area.

    Before I remove the valve cover, oil pane, and timing cover I forgot to turn the pistons to DTC. With all these covers removed, can I still rotate the engine clockwise to DTC for checking each valve clearance at this instance? The chain tensioner and chain guides are still un-touched, just the cover removed.

    The other question is how do I prepare the timing cover for RTV re-seal? What solvent should I use to clean the surfaces?

    Your responses are much appreciated.

    Yes, you should have no issues barring the engine over to TDC.

    Both the timing cover and mating engine block surfaces will need to be cleaned off of all RTV by using a scrapper, soft wire wheel or soft wire brush.
    Acetone or brake part cleaner can be used to wipe the areas clean.
