Another recent 5.9 failure 100% Contamination caused. Supply pump vanes very scored, usually a tell tale sign of debris in the fuel.

Thanks for the kind words buddy!

Patiently awaiting its arrival! :)

I would check to see if, while cranking/running the engine, the pump pulley runs true. I've seen where if the pump is misaligned, it will wobble a bit. Also, pull the cold start device off the side of the pump. If you need a step by step, Im sure there is a thread on it. Check that the ball...

I doubt it. Guy is a real piece of work. Have to deal with him regularly with this kind of thing. Regardless, the pump would have to have be rebuilt. it just got to be more of an expensive build from misdiagnosis. When in doubt, remove pump. ;)

Here is one that made my Friday. VE Pump from a 5.9 12V Third party field service tech argued with us that it was not a pump problem causing a no-start. Swore up and down that it HAD to be injectors. The subsequent prolonged engine cranking turned a simple fix into a much more expensive...

VE's are all very much the same in their construction. The early VW ones only had a 8 or 9 mm plunger, so the wear and fatigue factor was pretty low. Fuel delivery was around 35CC as opposed to 75CC-100CC on the larger cruiser engines, Also VW IDI (all IDI for that matter) used slower...

Very robust compared to other popular fuel delivery systems at the time. Very low failure rate compared with Stanadyne and Delphi pumps of the same vintage.

Thumbs up!!

Sitting with water in the fuel for long periods. See this often with low km imported diesels of all makes.

Here is a 1HDT Cam Disk that has just begun to dig into the case hardening on the inner portion of the lobe. The roller has a matching mark(not shown) on the inner contact face. I recommended to the customer that both the rollers and disk should be replaced.

On my two old pushrod engines, I check the valves once a year., keep the fuel filters changed with every other oil change, and I run a second aftermarket fuel filter in tandem with the factory setup. I would like to add a centrifuge to the oiling system, cant seem to track down a decent...

Bio is good when premixed with regular fuel. Its not recommended to use on its own. Lots of guys swear up, down, left and right in favor of bio and veg oil. I've seen a ton of problems and destroyed parts from its use however. Alternative fuel junkies are better off using a centrifuge to...

For Common Rail, the stanadyne lubricity or performance formula is great. I usually recommend bouncing back and forth between the two regularly.
