Vauxhall Dizzy

[box_one]

I'm after help again!

I have a circa 1995 Vauxhall 2lt with a Bosch Distributor - the engine runs a little "lumpy" so i fitted a strobe light and found that the flywheel and engine marks misalign by around +/- 3mm.

Is this normal?

It looks like the distributor is electronic with no means to adjust it manually? - do i have to go to a dealer to get them to set it up for me?

Any help / comments would be appreciated

I have a circa 1995 Vauxhall 2lt with a Bosch Distributor -

Taking it that this is actually in the Westfield its unlikely to be a '95 engine assuming its an XE and not the later ecotec. The XE (Redtop) was only produced up to late '93 except the turbo version that carried on a few more years. If its in the Westy and on carbs most will be run on the 2 ltr 8 valve engine distibutor and loom, which does give provision for timing adjustment.Otherwise it must be on after market, ie DTA etc, management system which will work on the later fixed type distributor from the donor car.

A little more information required to be more helpfull

Also techie queries like this will get abetter response in the techie section.

Thanks for the prompt response

The engine is a "red top" and as far as i can tell tell the distributor is fixed - i have a photo if it would help? but struggling to find how to attach it to this note! Doh...........

Not *completely* conclusive, but...

Is the dizzy cap a 'side exit'-i.e. the spark plug leads come out of the side of the cap as opposed to the end?

I do suspect you have a standard 16v dizzy fitted, if there was an 8v one fitted, there would be obvious slots by the mounting bolts to allow adjustment.

The 16v dizzy is likely to be 'driven' by an aftermarket ECU-which is where timing adjustment would be made if it was required...

HOWEVER...

Dont be *too* hasty in thinking it could be timing/ign problems. Have you done any other checks at all? Is the engine running carbs? Are these correctly set up, balanced, and checked for air leaks etc, etc? If the engine is 'unhappy' at tickover, the timing might seem to jump about a bit, as the ignition trys to keep up with the altering engine speed.
