Hi Ade If you're using a single tooth wheel to get the cam position isn't there an easier way to achieve that - for example a sensor in the timing chain/belt cover sensing a lump on the camshaft wheel - or a sensor detecting something on the end of the distributor drive. Using the distributor sounds over complicated, difficult to machine and heavier than necessary. Russell |

Hi Jeff - good post, that got me thinking along the same lines as Sparky over on the "How Do I??" thread. I can use a DTI on the existing plate to set the angle up, and then drill/bore the hole in the right place & at the right angle on the new valley plate. Russell - there's nowhere "tidy" to fit a single-tooth wheel. Obviously the cam housing is full of oil, and unlike (for example) the Lexus which has an external cam drive (because it's belt driven), the Jaguar is chain driven & thus immersed in oil. The next shaft of note is the dizzy drive shaft, which I can't avoid using (it's driven by a sprocket at the based of the "V", where you'd find the single cam of a pushrod engine). This is also bathed in oil, being just above the thrashing crankshaft. The dizzy drive is accomplished with a helical gearset at the end of the shaft, which pushes vertically(ish) up out of the valley plate. I plan to use that shaft, but I'll re-create the bottom of the dizzy (only smaller) and simply mount my 1 tooth wheel on the shaft, the sensor in the housing, and a small cap to go over the top of the lot. It should only end up around 2" diameter, maybe less. The main reason for the 40mm hole is to fit a ball bearing race inside, on which the shaft runs. I'll get it all drawn up this week so you can see where I'm going with it. |

Iff you skim off the mountnig lugs , your vally plate will be at 6 degrees and the distibutor square to it . |

Before you go any further the last of the V12s X300? has a coil pack valley plate and 2 x 6 pack coils units. My friend in Germany couldn't find one so made his own but here in the UK you might be luckier. http://www.jaguarforums.com/g/album/2795059 |
