Guest antgel Posted May 21, 2006 I'd like to set the timing with my timing light. I can't for the life of me find the timing mark aperture that Haynes refers to. Can anyone give me idiot-proof directions to find it? Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted May 21, 2006 Its almost impossible to find with the engine intale system fitted & even then usually hidden under the wiring. Find where the starter motor is bolted through the gearbox case & look towards the bulkhead around the case, there is a hole on the casing near where the block is, see the cutout in the picture below just to the side of the clutch lever. Good luck, I don't know of anyone that has tried it with full success. Graham. Share this post Link to post Share on other sites

I wonder how many less problems there would be around here if people got their timing sorted by the manual rather than a guess. In my experience, timing (and valve clearances) are the starting point for any well-running engine. I am very determined and will post back if I manage it!

Man3 0 Posted May 22, 2006 I tried to time my old 8v with a light many moons ago but couldn't get the light anywhere near the aperture with the engine in any sort of condition where it would actually run. Share this post Link to post Share on other sites

If you can get the timing marks lined up,even with the wiring and afm out the way coulld you not then paint corresponding marks on the crank pulley/cambelt cover and use them to strobe? (my old 1.6 engine had painted marks on the pulley and i assumed that was why) Share this post Link to post Share on other sites
Guest antgel Posted June 4, 2006 Good luck, I don't know of anyone that has tried it with full success. Graham. You do now! Step 1 is remove the blanking plate that Haynes doesn't tell you is there for the XU. Step 2 is remove the AFM and reconnect it, but tilted up - this improves access. Step 3 is use the light itself to forge a path through the wire jungle. It does work. I also rerouted some of a PO's wiring (they had rewired the brown multiplug with no thought for the best route for the wiring). My vacuum advance is broken. That explains a lot.

shepherdfte 0 Posted June 5, 2006 Seconded. did mine this w/e, and in the past. It is a royal PITA to find the hole, but it's there. Removal of the initial intake hose is essential, and tilting the AFM up helps. Much easier with a KnN kit fitted, unlike changing the headlight bulbs! Timing seems to flat around a lot at idle on these engines, but the marks steady-up above about 1k rpm. the trick is to find the hole with everything removed, and then clear a path to it as you re-assemble the wires etc. Andy Share this post Link to post Share on other sites
Pete C 0 Posted June 5, 2006 Tried to do this on a mate's car a while back, had the light all rigged up and shining through the hole, then remembered it was an Mi16 but we were still using the 1.6 flywheel so the marks would be a load of rubbish Share this post Link to post Share on other sites
