Duane-
I realize it is short notice on a breakdown this close to a trip. I started cutting my oil filter apart at 7500 miles and got the orange specs each time. Finally put the 575 gear drive cams with the Feuling oil pump and lifters at about 12,500 miles.
My oil pressure was still normal when the cams were changed. The outside tensioner had wear but the inside tensioner did not (normally the other way around). The oil pump rotor housing had a lot of wear.
Each engine is different about mileage on the tensioners. They don't belong in our motors.
Does Bob have anything else to ride to York? I don't know if an oil and filter change will get you there and back. Cam chest needs to come apart to determine problem and then order the parts. Not what you want to hear.
