2.5L 4D56 Turbo Diesel Maintenance Routine
Timing Belt, Seals and SHine up
Every van that goes through our hands gets “The Nomadic Maintenance Routine”. An integral part of this routine is replacing all of the belts and seals. If that means we have to pull the engine to replace the rear main seal (the seal sandwiched between the transmission and the engine) we absolutely will. During this process we meticulously clean the engine. While the aesthetic payoff is great; this process allows us to see any leaks once the engine is back together.

Cv axle boot
Over years of wear and tear the CV axle boots break down and rip apart. This allows dirt and grime into the articulating joint, which will destroy your CV axle. We make sure to check all CV axle boots, replacing when necessary, thus preventing CV axle demise:
Top End Adjustment
At Nomadic we want to ensure you are getting the peak performance out of your 4D56 Turbo-Diesel engine. The valve cover is removed and polished, while we adjust the valve clearance to back to .25mm. All of the valves, rocker arms and the camshaft are visually inspected for any signs or wear. If wear is present, parts are replaced.
At Nomadic we value transparency with our customers. Any questions about our process? Please shoot us a question on the Contact tab. More pictures of our maintenance routine are coming soon…
