Hello everyone from a newbie to both this forum (great!) and PSD's. I
have an '01 F350, 7.3 /auto. I'm in the middle of what I thought was
replacing badly leaking doughnut gaskets at the top of the up-pipes. I
pulled the turbo and disconnected the bottom of the pipes from the manifolds, and when I went to pull out the "Y" with both pipes attached, the "Y" just lifted right off of the up-pipes! The flanges were both still in place, and the doughnut gaskets were intact. Upon
examining the pipes, it appears as though just the very tip of the pipes were inserted into the gaskets. I would have thought that the
pipes should have gone all the way through with maybe 1/4" sticking out the top. Truck has only 75K on it, and it doesn't appear that this
stuff has been replaced before. Anybody ever heard of these pipes being too short from the factory, or is there something else I'm not
thinking of? I also read on here somewhere that you can use doughnuts
for a Chevy truck, because they are thicker to get more crush. Is this
a good idea? Final question- I'm thinking of adding an EGT gauge, where does the pickup sensor for this go? If I need to drill a hole somewhere I'd like to go ahead and do it now. Sorry for the long post,
and thanks for the great forum.
