I checked my timing.....

.....and it was a bit out!!. D reg 3.5 Efi RRC that has been down on power and pinking like hell under load. Got hold of a timing lamp and read the BoL to see how to adjust it.

Warm up engine Attach timing lamp pick up to No1 Cylinder Disconnect Vacuum advance pipe from dizzy Point light at timing points Cant see timing points, so clean them up Point light at marks and blimey thats a long way out!!

The pointer was on the 'o' of 'Before'!!. According to the book it should be TDC +/- 1 degree. Not what I had which I worked to be roughly 6 or 7 degrees before TDC!!!.

A quick rotate of the dizzy and things are how the book says they should be. It's like a new car, it pulls up hill, no pinking at all and best of all the MPG seems to be much much better. Next step will be fitting Polybushs.....must get the gas axe ready!!.

Just a thought, but when you had the timing light connected, did you check the centrifugal advance was operating?. I had a similar reading when the distributor had seized in the fully advanced position.

Well say goodbye to lovely ride & compliant suspension then...

Rubber bushes are there for a reason

good point. You can get it working again by application of thin oil, and wiggling it backwards and forwards (using the rotor arm) till it moves a bit again, then leave it to it's own devices and once it's warmed up and run a bit, it'll be working fine in a few days.

that's what mine did, anyway.

and another thought. has the engine been running on LPG? it might have been considerably advanced if so.

The auto advance thingy is working ok, well I think it is. If you connect the vacuum tube to the dizzy with the timing light on the marks you can see the timing moving. My friendly mechanic says this is correct.

As for LPG, AFAIK the car has not run on gas at all. When i bought it th guy had just changed the water pump, so I'm thinking maybe he knocked the dizzy whilst doing this. The bolt on the fixing clamp was very loose as well. This was found whilst trying to cure the ever present oil leak.

Vacuum and centrifugal are two totally different means of adjusting the timing.

The centrifugal can only be checked by running the engine ( vacuum pipe disconnected and blocked), and raising the engine revs whilst watching the timing marks.

Full centrifugal advance will be reached at approximately 2500 rev/min, and will read around the 20-25 degree mark (ish).

however, you can find out if it's seized by lifting the distributor cap and wiggling the rotor. it should move a few degrees and spring back. how many degrees depends on which distributor advance set it has fitted.
