CM 871 Timing

[2dlb]

Yup Rawze you is right. Shitty work. Finally got this truck in the shop. It was sold as rebuilt engine with documentation. Truck ran like shi#t bringing it home. So started with Insite and found no parameters for anything related to DPF or EGR. I noticed that the Turbo was running about 30,k rpm and when you stuck your foot in it it would spool to 85,000 rpm :oh:. Boost was bouncing to 30-40. SO, Pulled DPF and DOC pics attached (i think). Went to pressure test A to A, failed. Turbo is pumping oil. actually the leaks in the ata are easy to see, there the ones leaking oil. 2 year old cooler, Block plate in intake. (free give away). front cover is leaking so pulled it. When i pulled the bottom idler gear the one bolt was covered in silicon ????? Looking in at it againi see that 3 holes go into the water jacket and the one below the oil gallery is blind. Thats the one that had the silicon on it. Local dealership tells me that that is common to find. Any thoughts, This truck had a history of coolant leaking in to the oil is there a chance that coolant can pass by the bolts that are into the coolant jacket.
Thanks in advance Gents
