Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Does anyone know the 'exact' spacing, centre to centre of the coil pack fixings on the M96 engine. Yes I could remove a coil pack and measure but wondered if anyone has bench measured or has engineering drawings? I have two coil packs where one bolt has sheared. I am thinking of making a ally bar with a 5mm hole one end to fix to the remaining fixing and a bigger hole the other end, to take a drilling guide. There is still a slight risk of drilling off, however 2 of the 3 planes will be accurate. Perhaps one for MisterCorn maybe using the drill guides from his abs jig? Any thoughts welcome! Regards Ian

POST 2 / ORIGINAL POSTEROriginal post

Just to add, this winter bumper and exhaust boxes coming off to do a few things so ideal time to tackle the issue. IIRC they are the middle cylinders so should get the drill in!

POST 3Original post

I can measure it from a cam cover tomorrow. PM me in the morning. MC

POST 4Original post

To get it super accurately I would measure from a coil pack with calipers. Looks like 57mm to me though from this. If I was to make up a jig I would do as you suggest but have an expanding section to go in the hole where the coil fits to clamp it in place. I'd get a scrap valve cover to mess around with first, they should be easy enough to get hold of as there are plenty of damaged heads around. MC
