    So I did this little mod when the engine was down.
    The brass piece is a 1/8 pipe compression nut, filed down shorter then hammered into a cleaned out hole where the ball goes, to hold the ball in, that little cork thing is a joke, gums up and when you clean it .lets the ball fall out.

    the second pic is just too sexy not to post.:eek:

    Forgive my memory, but did you have an engine failure and you tore it down recently? Or are these pics from when you went through it before?

    Thank you for posting these ;Sweet

    :rotflmao :rotflmao :rotflmao I'm 300 miles away at the moment getting started on my mom's Honey-Do list :angel: be back behind the wheel in a little over a week. Between driving to L.A. last week and up to Eureka today, it's Amateur Hour on the road...I think people have decided that the minimum safe following distance is best measured in millimeters now cookoo

    Good to hear that these are "old" pics ;Sweet I was worried for a minute there...

    Happy New Year!!

    That little check ball allows the air to purge out of the cooling system when you are refilling the cooling system. If its missing then ou have coolant bypassing the thermostat all the time... Not a good thing but not a really bad thing like running a non factory thermostat....:sly

    ok so what he did there was remove the check ball and replace it with a brass fitting so in essence coolant is now bypassing it constantly. sorry but im not really understanding the reasoning behind doing this

    No the check ball is captured by the brass fitting instead of that stupid little cork disc.

    Makes sense ;Sweet How does one know if the thing fails? Assuming it sticks and flows coolant (when it should only flow air) does it make enough difference to notice?

    Also its hard to grasp the concept of lifting heads when looking at all those studs in your pic! Even with the factory bolts there are so many per cylinder you wouldn't think spitting gaskets would ever be an issue :eek:

    Those studs add so much more clamping power to the head gaskets. A stock new head bolt breaks at 153,000 psi and these studs break at 200,000 psi... As we have seen... Dyoung has boosted to 28 lbs on a used set of head bolts. Adding studs is adding insurance... Most here can't or wont boost as high as has been proven. I personally limit boost with studs to 13 lbs. I know I can boost higher but why piss of the idi gods...:angel::sly That check ball can sometimes be "tested" for functionality by squeezing the upper radiator hose quickly. Listen for a click sound from the thermostat housing. If the neck is off the engine just shake it and listen for the clicking sound....:sly
