Customer Satisfaction Program 21B26

So today I got a letter from Ford telling me that my hand-built Niche Line engine may not have had the secondary timing chain tensioner properly activated during assembly, which can result in a loss of camshaft timing.

Ford is offering a mobile (on-site) inspection of my car. So, I'll let them come look at it I guess. The bulletin doesn't say not to drive the car, but now how can I drive it knowing it faces catastrophic failure if the cam timing shifts and helps introduce a valve to a piston?

EDIT-I searched the forum under just "21B26" and found a discussion on it. It's referred to on this forum as a TSB

There are 2 threads on this already One in the GT350 forum. https://www.mustang6g.com/forums/threads/tsb-for-secondary-cam-chain-tensioner.158799/
And one in the GT500 forum. https://www.mustang6g.com/forums/th...hain-tensioner-service-guide-attached.158780/

You can check it yourself with a small inspection mirror. Not all dealers offer mobile inspection service. So you may have to drive it in anyway.

Thanks Bob! Started reading through the posts. This forum is amazing for the info it provides.

I’ve not driven my 2020 GT350 much this spring, since picking it up in Nov 2020 and promptly garaging it for the winter. It’s at about 500 total miles on the odo and hasn’t seen north of 4000 rpm, and now I’m glad I haven’t put too many miles on it.

Been armpit deep in restoring a vintage Vietnam-era armored car (see below) so the GT350 took back burner this spring. I was bemoaning that fact, but now I think I got lucky.........

Betcha that would get some praises at the local Cars-n-Coffee!! That’s cool and looks great!

Thanks CJ! I’ll let you know how it goes. Goal is to debut it at a local show on Father’s Day. Currently undergoing service on axles, bearings, brakes and clutch hydraulics...... it’s a 1969 Cadillac Gage V-100 and was sent to Vietnam in the fall of 1969, so I feel like a caretaker. I think it owns me, not vice versa. I’ll get it rolling soon! A friend of mine has one and says it’s a C&C hit, so I’m sure it’ll be well-received. Primary function will be to support veterans events. Working on this thing makes cars seem easy!! Wheels are 500 lbs each. Maybe it needs CF rims.....

I think I’m good. Explains why my motor did not grenade.
