"Just rebuilt third engine with your systems. Works great. On the 2.5l 174ps no more starting problems perfect running at idle consumption approx 1.5 -2 litres less."
"I did it the other day on my 2.5 Tdi T5 bus, really worth it, no more diesel in the oil and starts perfectly! Seats were already badly affected before!"
"My "short" report: The quality of the holders is perfect, cleanly milled - the delivery was fast.
Condition of the engine: traces of wear after 215,000 km (engine has run about 120,000 km long distance) on the camshaft low - no grooves, all cams smooth, partly a little "polished". The elements had barely worked their way into the head. The o-rings of the PDE's were still very good, hardly/not worn, as you often see.
The rebuild: We installed the PD holders 2 days ago in my T5 1.9 AXB - a pure precaution, no defect. The engine ran so far at cold start a little (PD-)rough, but then always astrein. The change of all sealing rings goes fast. One must work very cleanly. Therefore clean the PD element carefully, the nozzles also and also the bore in the head. The holder is screwed to the PDE with 2 small countersunk screws. Therefore the small flat iron and the two original screws are omitted. We tightened the new screws only after feeling, however, secured with Loctite. The new (expansion) bolts for the bracket and also the bolts of the rocker arm shaft are tightened one after the other more and more and then with torque+angle. The cam followers we have adjusted for lack of dial indicator free eye (PDE at the lowest point and 180 degrees back).
Conclusion: The holders are top quality, very accurate fit and the installation is for mechanics without problems to make - time required for 4-zZlinder about 2 hours. I would buy the parts again. They create confidence compared to the original holders. A big thumbs up to the developers and the whole team!"
