Although there was no wet marking, I’m bit suspicious of the black marking (not the obvious dark brown/black marking at about 5 o’clock position)
along the crankshaft and the lip of oil seal.
Probably best replacing the oil seal this time.










The usual melted CRK/CYL sensor potting.
Once the cam shafts are off, will decide whether to replace it or not.

It’s going to take some time cleaning the back plate…..










The usual story with the valve covers.
Not too much blowby sticky debris so good news but still, some time to be spent for cleaning....
In fact, I think I will spend much more time removing all these black liquid gasket everywhere…..



Time to remove all 4 camshafts.

    How easy is it to remove the Woodruff key? Do you replace it or reuse?
    The crank sprocket: do you need to press it out, or does it just come out easily after the key is removed.
    The seal: Do you use a seal tool or do you drill in a pilot hole, attach a screw and pull it out
    Finally, do you apply anything on the new seal (between seal and housing) at time of installation.
    Thanks Kaz, excellent work!

    The key should come out fairly easily. If not, the internal wall of the TB drive pulley (sprocket, as in your post) has corrosion.
    I normally re-use the key unless it’s heavily damaged.

    And same for the TB drive pulley. It should slide off very easily once the key is removed.
    If not, you must clean the internal wall where it sits on the crankshaft. I only had to replace it just once in the past.

    I’m too scared to use any sort of drill, screw, etc at the seal especially around the crankshaft.
    I normally use automatic centre punch at adjusted force as you have full control of the position on where to apply the force and the angle.

    Just use thin coat of water or diluted soap to assist the installation. The key is to use the proper tool.
    Be creative.
