CM 871 Burnt Valve
Good Morning Everyone, I hope you are all well in these times. I have a CM871 came in running rough ran insite and noticed in cylinder cutout that the truck would stall when u attempted to cut out 4,5or 6 with cylinders 123 shut off. the more i listened u could here a miss. Figured cyl 4 was the culprit pulled intake and injector and found the intake valve on 4 burnt through. theres about 500k on this motor and the crosshatching looks good i am wondering if anyone has had success with resetting the liners which im sure are gonna be lower than .014.I wouldn't even consider it under normal times and probably shouldn't now but was curious.
Thanks./uploads/202003/post_4626_1585653175_3fb44e3681d54c0714c042608e0b7cbf.jpg./uploads/202003/post_4626_1585653195_d5aa8200272095f2651c05d89201eb59.jpg./uploads/202003/post_4626_1585653214_671dfb842654ac382c7858dfef2f7f9c.jpg./uploads/202003/post_4626_1585653238_5e277745819ce1a069914891a56f229e.jpg./uploads/202003/post_4626_1585653253_253b49a5b054861fd6bec090a583c495.jpg
