V8 firing order

[Ian V]

Help !!!

I've been giving the engine bay a clean up tonight, and I think I've got a couple of leads mixed up. Anyway it sounds to me missing on a cylinder.
Can anyone post a diagram showing firing order viewed from front of car.

Firing order is 18436572. 1 is the front/nearside cylinder, 2 is the front/offside cylinder and so on. Hope you will remember to take careful note of where the leads are *now* before you disturb them any further, could be the leads are correct and there's some other problem.

Cheers,
Peter Humphries (and a green V8S)

Thanks Peter,

Problem solved. I have just fitted new plugs and leads and its back on song.

Scuse the question if its daft but is there a number 1 position on the distributer. Think I may have mucked the lead oredr up as well. Must remember to mark them next time.

The dizzy cap is numbered 1-8-4-3-6-5-7-2 with the 8 & 4 being towards the front of the car.

Pre '87 and post '87, Rover recommended two different routes for the ignition leads - see the Haynes Range Rover manual page 13.46 for the two diagrams.

No, the cylinder layout is 1357 on the left/nearside bank (1 at the front) and 2468 on the right/offside bank.

One of those day's. Cannot get it started. I have plug lead number 1 frontmost on the cap then it goes anti clockwise 1,8,4,3,6,5,7,2. Flooded again so the plugs are out for a while to dry out. Had a spark, changed coil and now have a better spark. All the ingedients seem to be there except the bang.

Er, my reference was to the dizzy cap, not the cylinder bank.


Jeff might have become confused, as his reply above reads, "I have plug lead number 1 frontmost on the cap then it goes anti clockwise 1,8,4,3,6,5,7,2'.

Of course, the exact position of the cap is less material than the position of the rotor-arm at TDC.

BTW, and as noted on his other thread (<a href="http://www.pistonheads.com/gassing/topic.asp?h=0&f=12&t=67405">www.pistonheads.com/gassing/topic.asp?h=0&f=12&t=67405</a> the "anti-clockwise" is wrong too.

When you need to replace the leads, get yourself a set of Magnecor leads from ACT - excellent product and they're numbered too (usual disclaimers) - Streaky

Thanks for that, can't chase it this week but will be on the case next weekend.
