Marelli distributor
Evening all. I have made a schoolboy error regarding the distributor on my 5.3 89 marelli car. I removed the distributor without any timing up thinking it would drop back in where it came from. I'm not sure it has gone back in the same place it came out of even though I didn't turn the engine at all. Can anyone tell me how I can now make sure it is in the exact correct place? Many thanks for much needed assistance with this.

TDC is marked on the timing marks on the front damper. Remove the spark plug and stick your finger in the hole as an assistant rolls the engine over. On compression stroke it will want to push your finger out of the spark plug hole.
Socket size for the crank damper bolt to turn the engine is 1-5/16"

Remove the bolts on pulley extensions on the front. In the harmonic balancer you'll find a line. This will align with the sensor's bracket underneath. Then check to see if 1A is in the correct position. Refit the dizzy, align the making on the dizzy and you're ready to go.

Will this distinguish between TDC on the exhaust stroke and TDc on the compression stroke?

No, but on the Marelli the 3 tooth wheel only lines up with the VR sensor for TDC (actually just before TDC) on the A bank, so lining up the TDC mark on the damper and a tooth on the reluctor you should be TDC on 1A. I would still pull a plug and double check.

Yep. Double check is better than later on having it fire at the wrong moment.

Firstly thank you all for your assistance. I should say that the car has been running ok since I did this a few months back. The car has not been driven though and run for no more than half an hour. We didn’t turn the engine when it was removed and replaced it exactly as it looked in the photos I took prior to removal. Is it possible I just misaligned the cap when replacing it which caused the rotor to clash with the posts? It only marked the bottom set also.?
