    1993 6.5 problem I've never seen before!

    Finally had time to install the Pyro. Engine up to temp, Idle 200*, Cruise @35mph 400*, @65mph 600*, and at WOT up to 80mph 825*. I didn't have time to try a WOT run on a 6% grade, or with a loaded trailer. I do just get a wisp of smoke when I slam the throttle down and then its gone. I'm still...

    They are on the mark, the timing set was installed and double checked, and the IP drive gear was installed X to dot and doubled checked before the cover was installed. As I said the IP and cover marks are about a 1/8in offset to the right. I agree on the pump rebuild and specs, but this one...

    Sorry I haven't back with any updates. Ive been working long days and weekends and it hasn't left me with much time to work on the truck. I did purchase a MT480 on ebay for $50.00 less the Lumy probes, and it is in great shape. After talking with many friends across the country I found a guy...

    Please let me know what you find. I haven't had time to search the tag numbers yet, and can't get the shop that installed it to talk to me.

    All of the engines I rebuilt except for a few had chains in them. When I worked for ODOT in the 90s we rebuilt a lot of these and all had chains.

    Well you are right, 93 never had boost reference waist gate. Why this was done I'm not sure, but it's there. I am wondering if it is a actuator from a 95 or a custom unit. there is a boost gauge in the truck and when I drive it tomorrow I will do some testing. I did drain and flushed the...

    Hello everyone, I'll start at the beginning. My son in-law took his 1993 K2500 6.5t to a shop for a hard start. The shop called him and said he needed the pump rebuilt and new injectors. He gave the go ahead, and got the truck back, in 3 days it was blowing black smoke (never did that before)...
