    Main bearings... What's this?

    Hi guys,

    As a continuation of chasing an oil pressure issue i dropped the sump, changed the gauze and pump and was inspecting the bottom end and came across something i am not sure what it is?

    ImageUploadedByTapatalk1349002344.715086.jpg

    The centre main has a "tang" like thing each side of the cap and they have quite a bit of movement in them (as far as the recess in the cap lets them move anyway).

    I assume these are normal but is being able to move them normal or does it point to a possible shell issue and loss of pressure that way?

    I dont want to just undo the cap as the bolts are £9 each!

    Also, if i was to replace this, can you do both upper and lower shells without removing the crank? Ie. insert the upper and spin it into place?

    Thanks, Neil.

    Main bearings... What's this?

    Think I will leave the bearings alone and seal it back up with a new pump and gauze then... See what happens!
    Thanks chaps

    You've roasted the engine twice with low oil pressure from a blocked pickup, and your not going to bother checking the main bearings even though theres an obviously discolored cap?
