Default Broke timeing belt updated pix

For any of you that want to see I think I found the problem of what sheered teeth off the timeing belt,(Or the aged belt let the engine run a tooth off for a while.)
It appears that the exhast valves became so gummed up that the engine ran too lean long enough to warp the head enough to slow the intake cam due to binding,It's tight even without the valves in.That would also explain the coolant boil.After seeing the oil clearance I wont run anything thicker than 0W30. (IMO)
Was going to build the head myself untill I found I need Cams,Lifters,seats and Exhaust valves.Also will need decking and cam rebores. I can buy a reman head complete for $495.

Hear's a few more.
By the way the PT ran flawless for 92,000 except for 1 quart of oil between changes.
1st syptom AC quit working well
2nd syptom Coolant smell but no puddle,found residue around water pump return pipe
3rd and last PT lost 50% power but got me home 4mi away
NO CK Engine Lights,Temp Gauge below middle.Coolant never got to low but had to add several times to resivior.

Wow, that is brutal!

When I got my PT it had a blown head gasket. The head was warped so badly half the valves and most the guides needed to be replaced. I've done a lot of head gaskets over the years and I don't think I've ever seen so much collateral damage. These heads don't seem especially sturdy. Clearly fine for their job, but not good at handling much beyond.

I read that this 2000-2001 is the sturiest head version installed,and it looks very tough except I wish it had cam bearings.The rest I can fix myself.

I'm betting you don't use synthetic oil?
I had head taken off a Dodge Spirit 2.5 L that I used Mobil 1 in - at 150,000 miles, and there was not a trace of brown deposits - all was clean & shiny - A valve guide had come loose.

I used Mobil 1 for the 1st 55,000 mostly all highway miles for 2 years,switched to a blended oil since moving here as I change the oil by months not miles now. I only live 4mi from work and 30mi from the beach.Another reason I switched was oil consumption,that didn't help with that issue.Like I stated I will only use 0w30 whatever once I finnish though.I see why FMC has gone to 5w20 in some engines.I also have tore down several engines very clean inside that were Castrol.I'm also not blaming the oil manufactuer for this problem,as my cylinder bores look new and never had a noisy lifter.As for the brown coloration my oil fill inlet has been brown since the 1st year about 25kmi.I Am wondering if all this carbon/sludge builup is a mixture of oil and small amounts of coolant.As a note I haven't mentioned the oil used in my PT yet.....

I don't get the "blend" idea. It admits synthetic is better, so why not use full synth?
I have never seen a % of how much synthetic is in the "blend" - 2 drops?

I'm not seeing any damage ...

Cams always have fatigue marks, but I've NEVER seen a lobe or rocker roller fail.
I have seen severe corrosion pitting on 2.7's, but that's due to poor crankcase ventilation, even then the lobes didn't fail
