Afternoon all,
After someone can offer their expertise on this. I'm a trained mechanic but I have zero experience with the PD engines.
I bought a 2004 T5 Transporter 1.9d with the AXB engine 5 years ago that was overheating. I found it to be the head gasket. Cylinder head was sent away so the surface could be machined. Head gasket kit, water pump, injector seals and all the intake/exhaust gaskets were replaced and engine was starting/running fine.
For the last couple of years this thing has not been starting well. I'm converting it into a campervan and I have a few other things I'm building so this has never been a priority until now.
Symptoms are hard starting, takes a long time cranking it over for it to fire up. Increasingly, I had to keep the revs up until the engine had warmed up, otherwise it misfires, splutters and dies.
Fault codes have been checked, on occasion there has been a camshaft DTC. However, once cleared and the engine is still not firing up straight away, the DTC does not return.
Over the last year I have done the following;
Replace glow plugs and relay.
Installed 1-way valve in fuel line to confirm lift pump in the tank isn't the source
Fuel filter has been replaced
Tandem pump replaced and adjusted fuel injectors just before Christmas
I've recently got VCDS on my laptop. Found that the torsion value was -1.7kW. Have now adjusted this to 0kW.
Compression test has been carried out with the following results;
Cyl 1 360psi
Cyl 2 380psi
Cyl 3 380psi
Cyl 4 370psi
The only noticeable improvement I've seen is that after replacing the tandem fuel pump, whilst it still takes ages for the engine to fire up, it no longer has much of a misfire when cold.
Just wondering if anyone has any suggestions. I'll be looking to invest in the revised injector clamps and replace the injector wiring loom while the cam cover is off. I'm considering removing the fuel injectors so they can be tested.
I've seen reports online that the injectors can wear a groove in the cylinder head and this needs to be sanded back so as not to damage/nik the seals when refitting the injectors. Is this a thing?
Cheers,
Craig
