i have a 1996 dodge diesel (mods in my sig) has 182k miles and i can start to see a little blowby which is pissing me off since i just put a engine in the truck becuse i bought it with a warped 9000s block. what to do

 

This is not always an indication of cylinder blow bye .... It can also be caused by turbo blow bye, it comes through the return pipe from turbo... Could be either hot side or cold ... Take your oil return line off @block ... Place a hose over the line and then put the other end into a bucket with fresh oil .... Leave plenty of room ... If you see air bubbles ... Its your turbo and a simple rebuild will do the trick ... Keep us all posted on your results

 

It could also point to a clogged crankcase ventilator. If it is, you can put a new factory unit on it but the design isn't that good. A better option is to put the valve cover breather on it from a Case (p/n: 2830784 and 4899194). There are a few more parts you'll need like bolts and seals, but the setup can be found with a Google search, I'm sure. Most of the ones I've seen use two (2 and 3, 4 and 5). Looks awesome, too.

 

Good idea ......

Also you can take each valve cover off and use a hole saw ... and have 6 smaller air cleaners for vents .... looks kewl, when there color coated too ...

 

I honestly wouldn't worry about a little blowby mine has some blowby and it is just fine but that's just my opinion

 

For what it's worth, a guy I know around here, David (BC847 on the forums) has blow by, even some sideways play in his pistons at the bottom of the stroke, and runs 7s in the 1/8th mile. It's his daily driver, too. He doesn't seem real concerned about it from the way he talks.

 

Lol... Wow .... I would not be real happy with slop at bottom of stroke ... Good way to oval out the bores and loose the whole rotating assembly. .... For what its worth ... If your real concerned ... Pull injectors and there lines and do a compression and leak down test

 

It would freak me out, too, but there aren't any diesel trucks I've seen at Dunn-Benson that would touch this guy. 7s with a VE pump in an extended cab 4x4? Blow by be damned.

 

True .... And .... Its his engine so ... Blow it up !!!!

 

I bought this engine as a short block I have all new hoses,gaskets and everything down correctly from ground up and the only thing I havnt done was check the pistons or messed with the hx35 which has 300k miles on the turbo and the injectors were rebuilt with all knew springs lifters head camshaft which is why I am concerned with a little blowby after everything was done
