Hope you guys can provide a little help. I inherited a 2011 XFR 5.0 SC recently. The person who owned it passed away in the middle of a repairs. Unfortunately, I received the vehicle with the cylinder heads off and disassembled - all of it unmarked. I think I figured out which heads are left and right but I'm having trouble identifying the cams. I did find a little info but I want to be sure. A friend who is a Ford enthusiast gave me this this morning. I understand the Jags use ford engines but would the setup be any different in a Jag?

Oops. Take out the Motorcraft prefix (YF3E) I have 6A273 AB, etc. stamped on the cams.

 

It's not a Ford engine, it was 100% designed by Jaguar, but it was and still is built in the Ford engine factory at Bridgend in Wales and uses quite a few FoMoCo stamped parts.
Get a copy of the 2010-2011 XFR Workshop Manual from my Dropbox here: https://www.dropbox.com/s/bet26xniua...kshop.pdf?dl=0
Also the AJ133 SC technical training doc here: https://www.dropbox.com/s/8y4iax9hm2...%20V8.pdf?dl=0
One or other of these should help with the rebuild.

 

Your cams should not -AB on the end of the stamped number.

But the 6A27x appears to be the same identification for inlet/outlet, LH/RH bank.

For example.

5.0L S/C with Tsubaki chain system
LH B-Bank inlet camshaft
AJ811993, 9W83-6A271-AD

 

Thank you Very Much for these. I will check it out tomorrow when I'm back with the car.

 

That is what is on the cams though. I looked at some pics I took but they don't show it well enough. I'll take some more tomorrow and post a link to them. Thanks for your help!

 

Thanks again for this info. I am not with the car yet to check for the AB stamp. I reviewed the pics I took but they weren't good enough to tell. Would you be able to confirm with these numbers that what I have for the LH/RH & IN/EX is correct?
