Has anyone completed a successful rebuild using an aftermarket rebuild kit? I rebuilt my D722 using a Friday Parts kit. Once I was complete the engine took a long time to start up, but it did run. It has a lot of blow by and the cylinder with the most compression only had 310 psi. The service manual states I should have 337-448 psi. I had the cylinder liners replaced, then bored and honed by a machine shop. I am wondering if the machine shop bored the sleeves too much or if the parts I bought were such poor quality that they have worn away. Any advice would be appreciated.
