valves

I took mine in when I hit the miles, the hours were around 10 when I had them ran. Couldn't tell a difference afterwards, but I know why they need adjusted. On the D1 or D2, I prefer the D2, just because it keeps the rpms down and as a result less engine braking, only preference.

Valves

Hi,

I took mine into the dealer and had the valves done along with the oil and such, can't remember the price but it wasn't real bad, and I didn't feel like messing with it at the time. If you do some searching around, it may have been on this web site on how to run the valves, someone had a step by step on how to do it yourself. They want you to run the valves after break in due to the valves seating and breaking in, they just want the clearance checked, I would guess it only changes a few .001's, but some may start to clatter a bit if you don't reset them. Loose valves I would presume means more wear and less air flow.

later,
