Hello everyone, as i suggest at thread i am dealing with a problem with my car over 1 year. Last year we restorated the entire engine but due to mechanists lack of knowledge about the car in my country they just set up wrong ignition timing and im looking for correct settings to make it right. Thank you for answers

 

As you can see, #1 points directly to the radiator hose elbow. the cap is keyed so it will only go one way and the clips are about 2:00 and 8:00. The firing order is 153624 clockwise.

 

So only thing i have to do put the pistons in right order and adjust distributor to start from #1 am i right?

 

I think I don't understand your question. Is the distributor out of the motor?

 

I didn't took it out yet. I've talk with a mechanic and we gonna took it out in 2 days but he want me to find out proper positioning and setting for timing up the distributor but i can't find it anywhere

 

If the distributor is in the car, then unless someone has removed it and put it back incorrectly, it is not the cause of whatever problem you have. On the 3.6, the timing is controlled by the pickup reading the front pulley wheel and the spark timing is provided by the electronics to the coil. All the distributor does is send the sparkwhen it is generated, it has no timing advance or retard mechanism in it.

 

Greg,

Is that also true on the early 3.6 XJS before they moved to the full electronic system as used on the XJ40? The PO hasn't said whether it's an early car or a post-88 car?

I had a 1989 3.6 for a while, and it was true for that car It was, in effect a hybrid of electronic control but using the dizzy to distribute the spark rather than full CoP etc.

 

Hi, the earlier 3.6 cars used the same distributor set up as the series 3 saloons, change point around 1986/7, in which case the timing is fully adjustable as anyone with a ‘classic car’ should be familiar with. With the vacuum pipe disconnected these early cars should be set up 18 deg BTDC at 2000 rpm , assuming this is a US spec car. If the engine has been disassembled then I would start at a static timing of around 8 deg, not that it should make any difference but No 1 cylinder on the AJ6 engines is at the front of the car unlike the XK ‘s which no 1 was at the rear.
If it is an earlier car and you remove the distributor its worth checking if the vacuum advance is still working and the centrifugal weights are not seized.
If however its a post 1987 car please ignore all of the above!!
