Engine/Transmission (1994 - 1998) Engine block heater

[GAmes]

I finally have my engine back from the mchine shop and reassembling it. Which way does the block heater go in? FSM just says, remember which way it came out That was a year ago. So does the plug go above the allen screw, or below it? '98 12 valve engine heaters are different

Element has to point down inside the block cavity.

Just checked the Phillips/Temro catalog.



That is installed correctly and would point the element down.



It's all good, man.

Gary,

Did the machine shop bore the block? If so, to what oversize?

 

[GAmes]

Thanks Mike, I knew someone would know the answer.



Harvey, . 020 oversize on the cylinders, crank journals were just polished. The guy said I had a very solid block, so if I go another 800k I could go to . 040

 

[HBarlow]

That's quite impressive when you pause to consider that engine had over 700,000 mostly working miles on it, was mildly modified, and only needed a . 020 overbore.

When I hear facts like that I take them as even more proof that the mighty Cummins is so far ahead of the so-called competition the Furds and GMs are not even in the game.

My guess is, if . 010 oversize was offered, it would have worked. And someone in another thread said the 5. 9 was a throw-away block... .

You can still sleeve the block if it is necessary. . Just sayin...

I think so too, but I didn't think to ask. It does go to show that visible crosshatch is not a good indicator of wear. It was the bottom of the cylinders that were out of spec. I hope they aren't throw aways. I have a '98 engine I will need to get rid of soon.
