Sorry for the stupid question, but I'm used to aircooled engines and this water stuff has thrown me a little
I have just fitted a recon DG engine in my bus (1.9 auto) and want to time it absolutely properly, to keep Elite VW happy. As I understand it, I do the following:
I then run the engine up, with the vac-advance hose plugged and the ignition stabiliser unplugged, with the two plugs connected to each other? At this point, what should I be looking for at what revs? Thanks in advance guys - the MOT's first thing tomorrow so I'm bricking it!!! Richard Edited by Globbits |

Timing is 5 degrees BTDC, vac advance unplugged and the hose plugged. Once you undo the vac hose, the revs will drop so you will need to speed it up with the idle speed screw. get it warm, the timing being on the piss won't damage it just sat there idling. Get it running, warm it through, I set timing when I am bleeding the cooling system, you need to set timing warm. Once it's warm, temp gauge at half, auto choke off then start timing it. If it's got DIS then unplug them and plug the wires together. 2 marks on the pulley, the big fat one, on the left is the TDC marker, the one on the right, the smaller one that looks like a chisel mark is the timing mark. Ignore the timing mark, go off the fat one ( TDC mark)and set your timing gun to 5 dgrees, then align the big fat mark (TDC mark) to the join in the crank case at 850-900 rpm. If you then set your gun to zero, and you have the right pulley on (because there is a chance the pulley is wrong and some of the timing settings do differ between engines) then the timing mark may or may not aligh with the case. 5 degrees is good for unleaded. Once your set then connect vac advance back up, the idle speed should not shoot up so adjust it back to where it should be with the idle speed screw. I should take about 2 minutes start to finish! |

You sir, are a star!
The previous engine was a DF, so I'll make certain the big fat mark is TDC before I begin timing (pencil in the spark plug hole and all that) My timing gun isn't posh and only flashes at ignition. I take it then that all I do is make a mark on the pulley 5 degrees BTDC (to the right of the TDC?) and time it so that my new mark is on the case split at 850-900rpm and all is well? Thanks as always! R |

I think you can normally tell by the engine sound whether or not it is "about right" anyway can't you? I mean you dont have a tachometer so how can you be sure you are not already idling at 1000 rpm? and not 850rpm. I havew firmly believed that the reason mine cuts out after warm but not run for ages was due to the timing but no matter what I do it still behaves the same. The timing gun I have is crap too, it has a wheel on it to adjust to match the speed of the engine. but I found putting tipex on the notch works well enough.
btw how was the engine conversion to a DG from a DF I am considering the same but you need new carb etc dont you?, and doesnt the water go through the inlet manifold on a DG but not on a DF? or did you keep your old DF inlet manifold and carb and just change the block?

Set the timing as per your instructions. My pulley only had one notch on and it was at TDC (checked using a pencil in #1 plug hole). Made a mark 5 degrees to the right of the notch, set that to be on the crankcase split and started her up. Ran like a charm! Followed the rest of your instructions and I barely had to move the dizzy at all. It sounds lovely - even with the noisy tappets at the moment Clartsonly. Long story, but my Caravelle had the DG pipework in place, but with a DF engine. It needed a replacement inlet manifold and then a couple of replacement pipes, but just because the old ones were perished. I'm afraid I don't know the proper layout of the DF engine enough to advise. All I can say is that the power difference, even moving her around the carpark, is very noticeable!!!! Bring on the MOT! (PS Wish me luck!) Richard |

Hey Skeeb
Engine's now done a whole 50 miles and all seems well with the engine so far As for Elite VW, that's a toughie. The engine itself is fine and half the price of the other "reputable" companies. But, I ordered it on something like 14th December and was told I might get it for Christmas! It arrived Feb 2nd , after many MANY excuses and "it'll be there this weekend"s. We actually ordered two engines from them and I'm having to drive there today (100 miles each way) to pick the other bloody one up because they "keep having problems with couriers"...... To be fair to them, I don't think they're set up to deal with individuals and our business is small in comparison with the large orders they supply companies. So, their service is poorer. This doesn't excuse them - just explains them. That said, I would use them again, but I'd take my bus there and watch them fit it before I parted with any cash! Richard |
