I was surprised recently with a few posts by new owners/members asking about the seal needed on the pick-up tube where it is secured to the block within the oil pan.
Even had someone mentioning opening up a newly acquired parts/spare engine and finding the retaining clamp not installed/missing
This rubber seal must be in place for proper oil pressure flow otherwise you could suffer cam failure.
So just be sure this seal is in there and the clamp is secure before wrapping up the bottom end
