Case Puller Head Gasket Trouble

Die Hard Case · Jun 29, 2013

So this morning I just got to put in a new set of injectors in our 930 puller started it up after installing them while warming it up noticed the head gaskets seem to all be seeping and bubbling. This is a 451bdt with 10mil pump and 4x20 injectors It has had copper gaskets in it for two years with no problems I was wondering if we should have torqued them higher than a normal gasket or not or if having the timing advanced to far causing precombustion caused this any advice will be greatly appreciated

I ran Clark copper gaskets in mine for a few years with a small coat of rtv around water jacket and oil passages with no problems even reused them a few times with the torque spec from the shop manual also a 451 bd

What kind of timing are you running it would be hard on gaskets if to advanced. I run most of the ones i build around 34btdc or so. Have your sleeves been machined for wire fire rings? I have sleeves machined to insert a wire fire ring. I then use stock gaskets after i remove the stock fire ring and i have had no trouble. As far as torque i wouldnt get carried away over doing it.

As far timing I have the pump advanced almost as far as it will let it travel I have been toying around with that still I may have to try and back it back down to that 34/35 as for the only thing that has maybe changed is that I had put thermostats in it and it hadn't had any in it prior thus never getting the engine ever very warm so I am not sure if when I retorqued the heads that it never got warm enough to really set them It doesn't have fire rings either as to your post Mr Hillbilly Im still running the gaskets I had gotten from you three years ago we had never had the engine tore down since we installed them

Here is a video of the latest project im doing for a couple freinds. This was the first actual run. It trashed the turbo on that run. I got 75lbs of boost before i started hearing the sound on the intake pipe change. We at least know it should run that gear with some more fine tuning. I got 21.2 mph and the winner only got near 23. So back to the drawing board on the turbo. I would try to retorque yours since you can get it up to temp. Thad

Thad,

I don't know how to post a youtube video to this site so go to youtube, Rome tractor pull Tyler Woolever Just In Case 930 and watch Case Pa. style. If someone knows how to post it here please do. East coast Case pullers are proud of this "930" and it is right there with the best of any color.

I want to add, this is a stockblock Case engine not another color driveline with Case tin.
