This a case in point regular scheduling of maintenance is cost effective in the long run. You always say what’s true and best for your customers great diagnostic work again thank you sir
Regular oil changes at 20000 miles or less and overhead adjustments is key. I do my adjustments once or twice a year because of the trucks mileage. Good luck everyone and be safe out there.
Want to take care of your unit. Do valve adjustment every 200k. Doing so Eng head will last you over 1 mill. Also per freightliner. It needs to be at or above 85%.
Still don't get fooled guys, that engine can blow the valves in next 100 miles since they were so tight for so long. That's another danger of late adjustment
I have a little issue with the abs I kw keep getting code spn810 fmi14. I cleaned all the rings and abs sensor. Is there anything else that I can do? Or what exactly do this code means? (I’m not a mechanic I’m just an o/o trying to fix my truck) thanks for the info.
Next step is a valve adjustment. Have a good mechanic run the overhead. But if the number 6 cylinder has low compression, have the mechanic let you know what they find. How tight were the valves on the number 6.? The intake will most likely be out of adjustment the most.
My mechanic did valve adjustment and after that compression went to 96% on sixth cylinder. But it get worse after few months. Right now is around 83%. He says only replacing cylinder head will fix problem
@spicemerchant636 he is correct, the valves are worn and it will continue as the truck is used. Common issue with the DD15 2015 and newer. I think once Detroit switched to the single lobe on the intake CAM.
Typically you are looking at $350-450 depending on the Cascadia you have. The short nose Cascadia will cost more because of the way the engine sits inside the cab.
