People have said that you can install a small bracket on the back of the head, using the distributor holes, to keep the cam seal from blowing out.

Does anyone have a template for how big and how far apart the holes are?

    See the last two replies in this old thread.

    The moral of the story is keep the breather clean, as you have already found out.

    Those who use synthetic oil don't have this problem. But switching to synthetic may cause leaks where you had none before unless you renew all old seals. Or so I'm told.

      Yeah, my problem is that the breather seems to be breathing just fine yet I am still facing crankcase pressure.

      I may leave that seal retainer off now after reading this, thanks.

        It sounds like you poked a hole somewhere in the breather box damaging it. You may have minimal flow but the box is still plugged up and not functioning like it should.

        Get a new Volvo breather box and replace the damaged one.

          Not sure how I am confusing everyone so badly with this one.

          I poked the hole in the clogged, oil drainback tube, deep in the block.

          It was clogged completely.

          I jammed a steel rod down there to see if anything would happen and eventually it broke through into the oil pan.

          Having that blocked should NOT have pressurized the block as the entire thing can vent right out the separator box, out it's big tube and right into the intake snorkle.

            We only know what you are telling us!

            If all you did was poke a coat hanger size hole in the blockage, that aint enough. Usually the box gets so clogged that it is impossible to clean you really need to replace it.

            There is a rubber tube that goes into the block is it still there and is it clogged also.

    I found the image below in one of Bruce Young's replies but I think it was originally from Don Foster.

    Edit: It is Foster's image but it was uploaded by rstarkie.

    You can dope out the overall dimensions on your own.

    Material? Maybe .080" to .125" aluminum or, I don't know what gauge, galvanized steel. Anyone? I thought maybe a short length of plumber's strap might work if the holes just happen to fall in the right place but I've never checked.

    I think this is a B230 head in the pic. B21/23 doesn't have the tapped holes, IIRC. Someone correct that if I'm wrong.
