Re: Problems with newly built DJ engine

Well, the increasingly bad running of the engine turned out to have a rather silly cause: my own inaccuracy. After having set the basic valve preload during assembly, I failed to tighten the locking nuts on the tappet adjuster screws of cylinders 3 & 4... Now the engine's running fine again. Tha...

Re: Problems with newly built DJ engine

So, this morning I took a closer look at the wiring of the Temp2 sensor. It wasn't even dodgy, it was completely loose. I fixed it with a brand new JPT-connector and the engine came to life pretty soon. But I was running irregularly and shaky, like it was on 3 cilinders. When I tried to run it at ±2...

Re: Problems with newly built DJ engine

Temp 2 unlikely, as that would just enrich and pick up idle revs, not cause a misfire or cut-out. Are you sure it's digijet, not digifant? Symptoms sound just like digifant when it increases fuelling until it floods, caused by a faulty loom, backfeeding through earth shielding on wire to lambda pro...

Re: Problems with newly built DJ engine

Thanks again. For the timing setting: it's spot on the mark on the pulley @ 10º before TDC. Of course I disconnected the vacuum and the single yellow connector and plugged together the two connectors from the DLS. And the ICV is buzzing. The Temp2 sensor is new, the wiring is a bit dodgy though. Tha...

Re: Problems with newly built DJ engine

Hi Maxstu, Thanks for the replies. Indeed: DigiJet. All ancillaries, including ECU, came from the previous engine and were working fine up until I started the swap 2 weeks ago. Fresh fuel was taken in right before the swap. Timing position, as mentioned, is on the required position. Temp2 sensor is ...

Problems with newly built DJ engine

Hi all, Over the last 2 years I built myself a 'new' DJ engine; apart from the casing and some add-on parts, everything is new: crankshaft and camshaft, pistons, cylinders, tappets, bearings, etc. Last week I replaced the old DJ engine in my van with this new one, taking all the fuel supply from the...
