    Default olds oil fill tube

    hi . I adressed the olds from pumpin the oil out the breathers... now I have it pumpin out the oil fill tube in front at 4800- 5000k. If I could just get it to stop id be ok! how do I get it to stop. Im thinkin there was a baffle that was supposed to be in the intake to slow it down and it probably missin or somethin. This thing is like a fnnn geyser. id like to cap it off or somethin. any suggestions besides replace with a chevy.

    Thanks in advance.

    Something is still causing a major pressure build-up in the engine block. How good is the ring seal?

    Seems like it is still a pressure problem. Never had that one with my Olds. PCV valve cured my problems. Doesn't seem right for the oil to get that high!! Try a gasket.

    You mite not have the correct PCV. You can seal the filler tube. Run a leak down test !!! That will tell you if your getting blow by on the rings. Water in oil ??? Mite be a blown head gasket also. I have has the same problems in the past, just need to do some home work.

    motor has maybe 4 hrs on it at tops. not blown headgasket. no water in the oil.

    i found this on ebay oil baffle so oil does not pump out oil fill tube. Im bettin you had that and i dont! previous idiot of my boat prob eliminated it thinkin boat would be faster with less weight.

    it's likely you don't have the baffle. I found mine after rebuilding the engine and figured it was no big deal...wrong. had to pull the timing chain cover and put in the baffle. end of story

    The ONLY way to install that baffle is to remove the timing cover. It slips into a pocket in the block directly below the fill pipe, next to the cam gear.

    Another option is to remove the fill pipe and install a freeze plug in the block. I did this with my Olds and ran it that way for 20 years. Only downside was that it took a long time to refill crankcase when changing the oil. Takes quite a while for the oil to drain from valve cover area back into block.

    Since you only have 4 hrs on the engine, it's possible the rings haven't completely seated yet thus the reason for building pressure. I'd do the leak down test to find out for sure.

    is the leak down test somethin I can do myself?

    I also dont remember and type of part blockin the oil fill tube in the Timing plate area.for me its probably both the baffle missin and the Blow by from new rings not seating yet....hence the geyser.

    If I could get that tube out id do the freeze plug dealio!

    Oldsquirt: How I get the whole tube out. I had tried before and couldnt budge itdidnt want to destroy it so I left it.

    thnks

    I always listen to oldsquirt. I took off the cover and yeah it's a job but it is the best way . I would always worry about the freez plug getting loose and coming in contact with the timing chain. sorry
