Diesel Geek, 100,000 Mile Timing Kit, 2006 BRM

[James & Son]

Looking for considered opinions. Good kit and was thinking about how far I should be able to go considering the following changes.

The kit was put in 2011 with 122,000 kilometers on the odometer.

I replaced inner valve springs at 142000 km; 15% reduction in pressure
from 147 lbs. to 125 lbs. open pressure.

I just replaced my cam at 222,000 km

I retarded the cam( torsion) considerably and rev only between 1200 to 2800 max.(power levels off at 2200/2500 rpm).

I am looking at 3 choices for belt change 260,000 km, 280,000 km and 300,000 km.

Assuming your crank pulley has got the part number ending with letter "H", the belt change intrval is 150'000 km. This is for stock engine.

The belts are known to wear minimally in PD engines. Regarding the rollers, the very same rollers are used in CR engines and those have 120k to 130k miles replacement intervals.

Personally, I wouldn't hesitate to replace at 300k km mark.
