Some decent amount of varnish. Perhaps the PP will continue to help gently clean some of it away. Not bad. Probably run on conventional or at long OCIs at one point.
 
Looks good. Thank you for posting

+1

Wear lines on cam lobes (picture 4) may indicate sort of abrasion wear ..... would be wise to keep to shorter OCI to help cleaning up.

Whislt those slight visually noticeable cam wear maybe normal and may cause no harm, I would envisage the spec'ed 0W20 provides reduced specific oil film thickness on affected lobes.
Hence increased duration of boundary lubrication regimes.

Boost up a grade higher at xxW30 to recover 'lost' specific oil film thickness may make sense.

Btw, I'm a thick oil man.

All complete speculation. Unless you've measured it, you don't know if it's worn.

Looks can be deceiving- there were some wear test results floating around a while back that showed two cam lobes, one was a near mirror polished finish, the other showed some signs of markings. Virtually everyone assumed the lobe with the polished finish had passed and the marked up one failed. Well they were wrong. The one with marks on it was still well within spec and the shiny one was below spec.

You miss the point....completely.
Specific oil film thickness is NOT about within lobe specs dimensionally or otherwise.
Ask Uncle Google.... if you don't know what's Specific Oil Film Thickness.
 
Thank you for sharing. This is interesting timing as I just found out this morning my 2007 Escape 2.3L VCG is also seeping. I can't decide if I want to do the job myself or not. The only benefit of doing it myself is to get some pics like this and see how mine is. I have owned mine since new.
 
Easy as can be to do this job. All you need is a quarter inch rachet, 3 inch extension, quarter inch 8 & 10mm deepwell socketsand takes about an hour to do. Also need some brake clean.

You said "visible wear". You really don't know that and you also don't know what, if any REAL WORLD longevity increases the OP would see by going up a grade in lube.

There are too many engines out there with cams that have lobes that look like that, running whatever 20 grade the owner can find and lasting for 200k miles- So I stand by what I said... Speculation.

Please read up on meaning and definition of 'Specific Oil Film Thickness'.
Then we may deliberate further on issues arising out from 'Specific Oil Film Thickness' , otherwise ...

I'm thinking about giving it a go. Gotta decide between Fel Pro and Victor Reinz for the gasket kit.

The Ford p/n is 1S7Z-6584-BA if you want to go that route.

No idea who makes it. I know it includes the spark plug tube seals. A lot of times when we do those, the timing cover/front crank seal is also leaking. At that point we replace the silicone RTV timing cover, crank seal, diamond washers, and crank bolt (tty).
