under valve cover pics 363k miles

Passenger side is the "dirty" side of the PCV system. All of the vapors and blowby flow through that side, hence the darker color. Driver's side is the clean side, which only sees air from the filtered air intake pulled through it. Difference in color between banks is normal.
 
Keep in mind that fuel formulation there is different from ours in the States. I have never saw a Police Inerceptor in taxi service after police abuse going over 250k on 5-20 without smoking.
The OP has been doing very well. Just keep your eye on the rear axles and bearings: that year had some bad ones, and the design is half-assed

Design is half assed? Based on what? It's the exact same design as every other semi-float axle over the last century.

Leaf springs are more safe and reliable. No need of new-fangled 'coil springs' or 'control arms'.

Looks good.



Could be at 500k by now if 10w-40 was used.

The high-strung, ubiquitous 1 and 2 point whatever, turbo(and super)-charged engines of today will NEVER reach these miles without at least one complete rebuild.

I believe there's a problem with the axles themselves- they apparently are known for cracking & failure on some years. I check the ‘03 MGM's one in my sig pretty religiously, they will start spewing gear oil out on a rear wheel before they fail.
 
Are those silver bands around the camshaft lobes wear or scars? Or are they "clean spots". I can't tell on my phone.

Wonder why the OP is using 5w-20 in Dubai. You'd think 5w-30 or 10w-30 would be better in that heat unless he's just using up some 5w-20.


may be you are right, i was thinking just do what oil cap says, Ford added GCC options like dual exhaust and rear air vents but that writing still exist

all original, valve seals replacement

On a more serious note - looks good. How's the interior holding up? Does it all crack?

I believe that's the oil pumps through the driver's side first then to the passenger side head. The oil passages on that side are very small, too.



5w20 is widely used here
engine run tight and smooth, some pinging if car abused in city driving especially when going uphill at 40 to 50 mph

I'm guessing that's from valve seals, a common problem on these engines, and has nothing to do with the type of oil used. The 4.6 in my Mustang smoked and burned at least a quart per 1,000 miles even with 5w-40. I replaced the valve seals and now there is no smoke and it does not burn a drop.

The lazy 1.49L engine of my last car ran same as new at near 600k with no complete rebuild---and without nearly as much varnish on cams, etc.

Yeah, I'm aware that there's a problem with the bearings wearing into the axles - most likely due to improper hardening of the axle shafts themselves. But, as far as the design goes, there's nothing different or abnormal about it. Same as a GM 10 bolt and a Mopar 8.25.
