The Cummins valve spring tool uses a long stud with a 19mm nut to compress all 4 springs at once. It is possible if they were using a impact on the nut they over compress the stock springs to hit the seals. Tim

 

Thanks Tim.... kinda foolish to compress the spring any more than you have to... you've got to wonder about some "mechanics"...

 

I'm a dummy and even I know better than that

 

Man, if that's why the seals crumbled I'd be really mad. Can you imagine some wrench jocky staring off into space and winding down the compressor? While you are paying top dollar for an expert and expecting to get a reliable engine. There's a lot more to this game than pulling wrenches.

Or did they just use the old seals that were ready to crumble?


DO YOUR OWN WORK AS MUCH AS POSSIBLE. Sorry for yelling. Best of luck to you Snox.

That's funny, John - I had the same mental image...

 

Hey give them a brake, The tire guy who did the springs is an expert with a impact gun.....I used a soft air rachet...but I'm used to using this and know what forces it binds to. Impact gun....Oh boy...

With a leaky valves you will haze...I assume they decked the block and milled the head when they did your fire rings....Those twins aren't super big... Did they install the oversized stock replacement valve seats or did they install bigger valves and or what exactly did they do to the valve train.

If your running big boost the valve guides will need frequent replacement unless Cummins or an AM has come up with something longer lasting. I think better retainers would be advised...I think DonM has them.

Take Don M up on the injector check....Bodies may test ok but in your bores....not so good. The connector tubes can be a problem.... I got some great advice on injector installation a while back and I think it makes the world of difference in order to get good injector body to connector tube connection. I'm hoping the author will join in as he offered excellent advice.

You can do a leak down test to see if the injectors are not getting their full fuel.
Those turbos with stock injector flow and a TST are not going to work. Kick in a Smarty and keep an eye on Rail Pressure and then you know the supply is getting there. You will need at least a Flux 1.5 with TST and Smarty to keep those twins rolling.

Have you done a leak test on your filter to intake. If you have a leak anywhere you will smoke alot and never get boost.

If you are leak free on fuel and air, and your HG is tight...IF they fireringed...then they used the 24V 2nd gen gasket....I'd have them pull the head and put a new gasket on there and redo the firerings. If the firerings weren't properly set then the new gasket probably is leaking...this is on their dime as this is Tuesday...long weekend work....it happens but it needs to get be fully checked out to get your confidence back. Good Luck, Kerry

 

yep guys... me too. I pictured " Tow Mater " from the movie "Cars" working in the shop

for 15 to 20K... that's not a good thing ! I'm sure their guys are a bit more competent than that but, it's pure laziness to use a air tool when building the head.

 

Yeah I'm hanging, by a thread, and about to let go!!

 

I guess that I am not totally sold on the idea that they were over compressed, they gave that to me as one of the possibilities. Just with all the pieces that the seals were chopped up into makes me think something else is going on.

 

Can't blame you there. It would surprise me a bit though, it's a good reason for it to have happen and once they were floating around, they may be been minced up some more.

I know how you feel though... it kills me I can't be there to watch every step and can only rely on a phone conversation.

 

whats up Ty,
Hows the truck coming? Hope ya get soon and it be right. Drop me a line

 

So what did you ever find out????

UPDATE????
