I WAS GOING TO CERAMIC COAT THE COMBUSTION CHAMBER AREA AND VALVES AND SEATS ON MY CYLINDER HEAD BEFORE I INSTALL IT BACK ON THE ENGINE, IS THIS WORTH IT OR JUST LEAVE IT ALONE THE CYLINDER HEAD IS A NEW FROM CUMMINS 610 HEAD FOR AN 06 TRUCK SERIAL NUMBER,





IM NOT SURE HOW THE COATING WILL WORK OR EVEN IF THE VALVES WILL SEAT CORRECTLY, ANY INFO WOULD BE GREAT... THANKS:cool:
 
MORE to the point, what do you hope to gain by the coating?
I WANT TO KEEP THE HEAT OFF THE VALVE SEATS, I JUST HAVE HAD A FEW BAD RUN INS WITH VALVE SEATS CRACKING AND DROPPING, MAYBE I SHOULD TRY NITROUS AND WATER METH, JUST TRYING TO AVOID LOSING ANOTHER ENGINE SO QUICKLY, I HAVENT BEEN RUNNING OVER ABOUT 1400 DEG SINCE I LOST THE LAST VALVE SEAT, THEY WERE BOTH ON 03 CYLINDER HEADS THOUGH IF THAT HELPS AND THEY BOTH SEEN 1800 DEG FOR A SECOND OR SO, I DRIVE THEM PRETTY HARD BUT NOT AS HARD AS I HAVE SEEN OTHERS AND THEIR SEATS WERE STAYING TOGETHER, I WANT TO BE RUNNING THIS ONE AT ABOUT 4500 RPM ALSO... IM TRYING TO FIGURE OUT THE BEST ROUTE AND YOU GUYS ARE THE RACING/PULLING DIESEL PROS SO I APPRECIATE THE INFO THANKS:cool:
 
the new updated parts from cummins will give you no problems.



here is a link with some info

here are the accual words from wade.







"Don, please explain to me in your own words how on Gods green earth, cam profile can lead to a valve seat failure?



i know first hand why they fail and thats so far out in space, i cant believe you of all people would say that,



this is why they fail



when these engines where manufactured, the valve seat it self was machined to an incorrect width and after x-amount of heat(egt) it will float in the head valve seat bore and drop with valve movement, and at the same time of it dropping it will allow the head to cool from the fresh and cooler air rushing past it and it will sieze in the bore (expanstion/contraction) and then the valve will slap the piston and severe problems occur.



because of this cummins now has an updated valve seat #(only after realizing there was a problem)---and guess what it's got a wider demention--for a tighter interference, it's 2-3 thousands bigger, and since the recall or shall i say update, there have been NO problems with updated parts.



now even with the old parts an aftermarket cam will help rid the high exhaust heat and further prevent heat soak better, so i see nothing but a win/win situation here.



now lets here your side!"









hope this helps you to better understand what happened to your valve seat.



as for your ceramic coating-- i would say no, because i think it will chip off and ruin yet another block.

I read pretty much that whole thread - interesting - but at what year did the Cummins start using the valve inserts - does my '02 HO have them, and have they been any significant issue in stock engines - or relatively stock?





And to digress slightly, here's a quote from that thread that addresses the concerns some of us have with the new, lower additive CJ4 oils spec'd for newest engines:



I know you dont understand that the Cummins B series camshaft is the highest wearing item in the engine, baring nothing else. But it is. This is precisely why Cummins, SWRI and many other companies tested the newest oil and cam wear is the area they test. Cammi's has a specific cam wear test for the Cummins ISBe COMP.

My mechanic has a 06 with a dropped valve seat... . I took another good 03 head to the machine shop and had them remove all the valve seats and replace with new ones with the tightest specs he could... That was my mechanics suggestion... I have about 2300 bucks in the head includeing a light port job... I sure hope it holds up... Wes

There ARE some helpful things that can be done to enhance reliability of valve seat inserts - we used to take a center punch, and carefully go around the newly installed seat, "upsetting", or "expanding" the metal surface next to the seat for a tighter fit.



We also, when possible, carefully peened the head material around the insert to slightly wrap over the upper edge of the seat to also help retain it - but that requires that the seat be slightly below the head surface.



All those extra steps were prior to running the valve seats, of course...
