    Ok im gonna try and make this as short as possible.

    -swapped cams and everything ok
    -did some burnouts and on way home oil light came on
    -cold motor 35 psi at idle and 5 at hot idle (checked with mechanical gauge)

    What the question is, is if i can band aide the problem by replacing rod bearings and switching to a heavier oil?

    right now i use Liqui Moly 5w-30 synthetic

    And yes i did change oil before starting engine (im thinking i should've done it twice)

    Any input is appreciated

    I packed that thing full of assembly lube and also primed motor prior to start.

    Ill replace it as a last resort since i don't feel like taking everything apart :/

    Bob, I am not here to piss in your cornflakes....the reality is.. that motor is coming out and doing bearings often doesn't go well in these motors. They aren't a SBC 350 and they are durable as all hell...right up until you let the smoke out.

    You let the smoke out.
    I drink..so consider that when reading my posts.

    spun cam bearing --> blocked oil feed holes ----> oil starvation

    new cam on old bearings = risky


    stop driving it immediately and rebuild

    Bob..having been in a similar situation ... the best inspirational advice I can offer is.. "the bolts shouldn't fight." Each time I told myself that one.












    You're right..it doesn't really inspire does it?
