Hey Bruceatlam,
The compression gauge set you guys are talking about. Will it work on the D650 engine without removing the injectors? I'd like to find one that utilizes the glow plug hole. Please let me know. Also, the SKU number of the gauge set. I have a B6100E that is showing blow by...alot out the breather tube. Basically, I need to find out the state of the motor prior to dropping cash on other parts...like a known bad radiator, fuel leaking at outlet fittings on injection pump, and a blown rear main seal. Thanks!
