I made a rookie mistake and did not mark my cam caps when performing a timing job. Everything was taken out and placed on the table in the same orientation. I was inspecting the caps and looking at the journals and noticed no forged stamp or arrows (oem).
One of the caps #3 R was a different orientation with other forged marking than the others. Meaning the M and the 5-11 was not the same orientation as the L #3. Each cam has a M and then 5-***. None of them are 1-8.
This got me thinking maybe I placed the cap down in reverse or somehow mixed them up.
I inspected each cap and tried to follow the small amounts of scoring compared to the journal on each side. Some where easy to match and the mirror caps (very good condition) did not have a pattern to follow.
The cams are now in, timed, and preparing to start up over the weekend. I thought maybe posting this would share some ideas if there is anything else I should consider before running with it. I was so detailed on everything else and frustrated I did not check for forged markings before removal as I would have painted/labeled each one.
Rotation of the camshaft felt fine by hand and rotation of crankshaft after timing appears to be normal. This is my first 5.4 3v timing job. Upgraded to melling oil pump 340hv and replaced all lash adjusters and roller/followers.
Any help is appreciated and thank you!
