Froc Posted July 8, 2017 Report Share Posted July 8, 2017 Hi all. I have a tappet-type noise on the Vitesse, but it's not coming from the rockers. Having listened to the engine running with a screwdriver to my ear (!), I am sure the noise is coming from the dizzy (amplified through the block). The car is running fine otherwise. I would appreciate a bit of wisdom before I go any further. Dizzy endfloat against the cam? Loose/broken bobweight springs? I would be grateful for any insight you can offer. Thanks (as always!)

Pete Lewis Posted July 9, 2017 Report Share Posted July 9, 2017 Drive gear end float can make a lot of tappety noise if its excessive, there must be some float or you sieze it theres worn dizzy spindle bushes and shaft wear due to lack of oiling does the rotor shaft wag around use a long screwdriver against the block and dizzy post and stick ear on the handle it will shownwhere the noise is eminating, dont get it in the fan , Or the HT leads one more excessive idea is the tail camshaft bearings can wear, this makes a tappet noise you cant trace,, quite common pete Link to comment Share on other sites More sharing options...
Froc Posted July 9, 2017 Author Report Share Posted July 9, 2017 Thanks Pete. Update. Looks like there was wear on the dizzy main shaft, as it has now sheared! If anyone can spare a cheap lucas 22d6 dizzy, please let me know! Link to comment Share on other sites More sharing options...

Froc Posted July 9, 2017 Author Report Share Posted July 9, 2017 Thanks Pete. I will look to rebuild the dizzy as a project. Have ordered an accuspark replacement in the meantime, as I need the car running. Here's a pic: Link to comment Share on other sites More sharing options...

Pete Lewis Posted July 9, 2017 Report Share Posted July 9, 2017 Colin, his floggle toggle had fell of his whim wham Froc, do check the base clamp may be different diameter to clamp the body there's two sizes of clamp so it could be too small or too big and if supplied with one theres changes /evolution how the clamp is bolted to the pedestal just to make something simple a nightmare Link to comment Share on other sites More sharing options...

JohnD Posted July 10, 2017 Report Share Posted July 10, 2017 That, surely is a Pi distributor, with the worm gear driving the Metering unit. Pi on your Vitesse? Good choice! John Link to comment Share on other sites More sharing options...
