i was getting my car vandalized by the neighbor so i decided to moved the car and park it at my parents drive way and thats when everything went wrong [emoji17], i was driving my wife car all this time after i got it back from the dealer...Why did you continue to run it after seeing the compression test results were that far off?
the cam only show scratches but no mayor problem, the last person who worked on the car was the dealer mechanic[emoji17]. when i turn on the car and felt the idle bugging out like it want to die out, right away it felts a big misfired so i shutdown the engine and opened the hood. saw the hole on the cover and oil everywhere, i was like “what just happened” i looked thru the hole where you put oil into the engine and saw the piece of the phaser broken. when i removed the broken phaser i decided to inspect the cam and thats how i found that head was damage and the part that hold it in place was the only piece losses [emoji29], the driver side has no sign of damageI don't get it, how the hell did this happen? I've seen some epic failures in my hobby days, but based on the previous issues, this one takes the cake. You went from us telling you there's likely a potential timing issue, to a dealer telling you to replace leaky valves, to some kind of timing catastrophic failure?
What are we looking at in these photos? I see the timing chain on the cam gear through a hole in the timing cover, and then a piece of the phaser, and some chewed up cam journals. So what failed? Are we looking at cam caps that weren't torqued and the cam shaft was riding dirty? Did the phaser break apart and smash the timing cover? WTF hit it? It's virtually impossible for the cam shaft to move unless more than a few caps weren't torqued, and even then movement would be severely limited. I have seen cam shaft gears snap off (rather the bolts sheered) and do this kind of damage, but the chain looks like it's still riding the gear, so this doesn't look like that. What exactly are we looking at?
I'd say take the head to a head specialist machine shop and ask if there's a miracle worker in the house. If not, it's trashed. Buy a new 3v head and slap it back on. Prevent whatever happened here from happening again.
How do the cams look?
i will inspect the oil this weekend and also will take the heads outThe biggest problem you have now is all that metal that circulated through the engine. That cam is history. So you need a head and at least one cam. You need to pull the other side and see how much damage was done by the metallic oil there. You are also going to need to check the rod and main bearings and oil pump. That looks to me like a lack of oil to the cam, it could have seized and that is what blew the phaser.
No part of this engine can be reused except for the reciprocating assembly after cleaning and machining.
I would swap in a complete 5.0 DOHC.

You are forgetting all of the ancillary equipment that also has to be changed. it adds up to a good sum of money and junkyard engines are certainly no guarantee. I would not put one in without a complete rebuild.
From a cost perspective, replacing the engine with the same, good used engine will ALWAYS be cheaper than building/rebuilding one. (and quicker to get up and running) Most used engines from reputable sellers come with some type of warranty (30 days~60 days) seems to be the norm. Rebuilding is time consuming and more expensive, but in theory, you end up with a brand new engine IF IT IS BUILT PROPERLY. A small error building can have catastrophic consequences. Just something to keep in mind.
