So I have a decent rattle on startup that goes away as soon as oil pressure builds, and I had the valve covers off recently and noticed the drivers side primary chain was pretty loose. I'll be taking the car to Pro-Dyno to have the work done, but I'm sorting the parts. I'm sure some of you are aware that Ford Racing makes a timing kit for the aluminum 4v 4.6 motors (Part Number M-6004-A464), but say it doesn't fit the B head cars. After a lot of research, I think I've isolated the major differences. As far as most of the kit is concerned, it will all work.
What works:
Timing Chains
Chain Guides
Tensioners
Secondary Sprockets
Cam Spacers
Crank Trigger Wheel
Crank Sprocket (Upgraded Single Piece Unit)
Bolt Kit (With an Exception)
Included Gaskets
What doesn't work:
Primary Cam Sprockets
Cam Bolts
So the kits are meant for newer cars with C heads, and that means the primary sprockets are different, as well as the included camshaft bolts being 10mm vs the necessary 12mm bolts that our cams use. My solution to this problem was to order the correct sprockets for our cars, as well as the correct bolts.
Sprocket Part Numbers (96-98 cams):
8AZ-6256-AA
8AZ-6256-BA
The bolts were the hard part, as I couldn't find the appropriate part numbers for our cams. The 10mm bolts are readily available, as are ARP replacements, at 20 dollars per bolt (x4 bolts). Luckily, all aftermarket 4v cams use the larger 12mm bolt size, and Trick Flow makes a bolt kit that includes 2 bolts, and equates to about 10 per bolt. The part number is: TFS-51800508.
If anyone knows of any additional differences, please let me know, and I hope this thread can save some research for anyone who needs to replace the timing set in their car.
