Diesel Machine

Diesel Machine is truly outstanding. Whether it’s precision machining or custom work, they handle every job with exceptional skill and care. I’ve been doing business with them for the past six years, and they have consistently gone above and beyond on every project. Their service is top-tier, their communication is always clear and prompt, and their commitment to quality is unmatched. I couldn’t ask for a better team to trust with my machining needs. Highly recommended

Guys were nice and helpful. Unfortunately the engine block was returned dirty full of metal and not washed. The deck was not surfaced per manual spec causing issues. The rod pin bushings were not set up properly leading to wild differences between cylinders. The valve seats were not cut correctly and burned a valve within a couple hours. The guide clearance and seals used within 10 hours of use. not only burnt a valve but had oil running down all 12 guides and blowing blue smoke.

Had them check and surface a set of 6.0 heads. Came back perfect in just a few days. Would recommend to anyone needing work done

Checked new head for flatness and valves seated. All is well and engine runs great.

took my 7.3 to them spent ALMOST $1000 got it back paper work said .40 over i bought the pistons started building the SB find out it wasn't .40 over it was .30 over!! had to send it back in and bore it out further do to my pistons bowls where cut already i couldnt send them back. To make it right the said they would grind my new valves and that's ill i wanted nothing else !! got my heads back finally got rest of my parts in started building and found heads where decked way too coarse put my snap on flat edge on it deep groves showing daylight and smooth in other places i should have learned my lesson the first time now all i can hope is maybe a copper head gasket will seal the comic gaskets wont! put few yr on engine pulled heads due leak #8 valves where never ground just stuck in h
