Is it possible that the oil pressure relief valve has failed or has debris stuck in the valve seat, preventing it from sealing? This could allow the oil gallery to drain back into the sump when not running.

I have successfully completed several agg conversions, the same as the 2e engine. I have always used the agg oil pump and swaped over the pick up to the jx one to account for the angle of the engine installation. it is a bolt on bolt off job making sure the gauze is clean. if you need a new oil pum...

TBH, I’m not sure. All I know is, it turned up with some pictures, some Whisky, and drives 100 times better despite me driving it very gently at the moment. Just glides along now. Best thing I did on the van in a looong time. Don't drive it like its made of eggshells, use the revs (4k is fine) and ...

Nice clean work environment makes such a big difference to the final result. I would have ported the AMC heads cos they can be a bit clunky behind the valve seats, doesn't take long and improves the cylinder filling efficiency a little. Do the JP flywheels fit a bit better on the crankshaft these da...

From the little I know about this subject, the engine requires a JX oil pump. Using the 2E pump is a mistake, it cannot reliably draw up oil because it was not designed to work at 50° inclination.

Pretty sure that Bentley has the diagram that shows you where to drill a smalll hole to release the barrel, its not in the Haynes Book of Lies, might be in the Autobooks Transporter manual that covers the Bay and early T3

Very good advice.

Epilogue. The wbx-6 has many unique parts. The engine itself is the least of it, the external control systems also use special application parts: The EFI ECUs are all L-jetronic (Digijet) with or without lambda correction, combined with a catalyst. No lambda = no cat. ECUs have plug-in EPROM chips s...

Torque multipliers require an immovable reaction point for the resultant torque on the multiplier body. We have a big one at work and unless eveything is well clamped down things can escape. Easier to go down the socket, T-bar and scaff pole route for the home mechanic. Next step is a FO big torque ...

We had our rack refurbished at Kiley & Clinton in Birmingham on the basis of multiple recommendations. I can’t comment on how it’s performed yet as we’re finally having it fitted to our van next week, but they were very professional to deal with. K&C are a proper firm, been around since for...

Its a well known problem iirc. Doable and documented but you need the JX tube and stick and a reference dimension.

You've got to be quite lucky with that technique, if the seal has a decent fit in the bore the screw just rips out. Been there, under the car, stopped the job, bought the tool, waited for delivery...happy days.

Hannover did things like this in Hall B (VW's SVO dept) and I have seen genuine photos of a JX auto installation, but it may well have had special valving in the box to acheive the required shift points. TheT3 auto box does have a very tall final drive which would actually suit a TDI so you could ge...
