Pulling out Trackhawk's blower, any info/things I outta know would be greatly appreciated

[ThawkDwN_UnDEr]

G'day fellas, first time posting but been copiously reading this here forum which has been great.
I'm looking at/pulling off my Hawk's blower next day or so via engine hoist. Reason being upon few very concerning factors I went ahead and swapped out the spark plugs for ngk lfr7aix iridium and didn't exactly like the state/condition of all piston tops and cylinder walls utilizing my borescope camera.

Oil and shredded teflon coating from the rotors inside the blower also....remove the lid and yep traces of blow by plus sections of actual wet oil around the kid's gasket.
Really don't think there's much point in me doing a compression/leak down test as with a heavy heart I've come to realize I've unknowingly been recently sold a Trackhawk with the motor on it's way out and I just wanna see for myself how bad I've been screwed over 🫤

I would greatly appreciate it if you guys could chime in on amy pointers/things to look out for and be aware of when removing the blower.
And importantly whilst viewing the blower attached to the motor from above with the lid off of it I gently can wiggle the right blower rotor through the opening and it has a tiny bit of movement.....thats not meant to happen is it and what could be the reason behind it.
Thank u

When you say "blower making contact with the case" are you talking about in the rear--as in the rotors have been pushed rearward?
If so, this is usually caused by an overheating event on the front bearings--they get hot, expand, and the only way for them to move is rearward pushing the rotors back.
If you haven't torn up the rotors or casing too badly it can probably be repaired/rebuilt--but probably need to replace all 6 rotor bearings.

Yes mate I meant with the supercharger lid removed and standing over the engine I place my hand on the right supercharger totor through the top opening and can see that it has a bit of play/moves a touch. Using a borescope camera also shows bad rotor coating sheering nearly 360 degrees around the left supercharger lobe....and the via borescope camera again the rear passage/casing has from what I could only describe long deep gouges/scratches....high velocity material/debris maybe....
I'll take some photos tomorrow of the blowers snout and the "strange rough metallurgy type change/yellowish discoloration" too.
I've yet to come across a image of something similar looking online which has me bedazzled.

Concerning to say the least....especially given the fact of what came out of the drivers side cylinders in my wetvac amongst the traces of oil/unburnt fuel/gunk on the tops of pistons through spark plug hole.

Reckon I've dumped the oil twice/flushed with cheaper oil in the ladt week then dumped again replaced oil with mobil1 and new mopar filters as I'm bit ocd however fear firing her up with all the "damage" I'm witnessing with the a heavy feeling of it breaking down on me also.

I'll try and post some photos, thank you for your response.
There is a place here on opposite side of country "Capa performance" who rebuild blowers/ihi'/vortechs that may be able to rebuild my unit.
Other than that I'm crap outta luck with hellcat builders/parts/specialists where I live let alone very hard for me to trust "specialists" and if push comes to shove I'll just have to order a complete block minus blower from the States via HHP or what not.

Cheers man.
Fyi attached are pics of what came outta drivers side cylinders in bottom of my wetvac....copious amounts of oil in cylinders
sorry if I upload same photos as before.

Hey mate, I replied to your post with heaps of photos just awaiting "moderator approval" for it to come out online....

Here's a couple of pics of what came out in my wetcvac amongst the unburnt fuel/gunk/oil on top of piston heads through spark plug hole....😳
And a photo of one fresh outta cnc machined type looking engine cylinder....NOT smh 😫

Are you saying the rotor touched the /side/ of the case, near the front plate?
I think the only way that can happen is if one of the front bearings broke its cage--or the plate stretched from thermal expansion a lot in just one direction (far less likely--maybe not even possible?). If the bearing broke its cage and the rotor scraped the side of the case, I'd think there'd be a /lot/ of damage.
If the rotors touched each other, sometimes the damage isn't so bad--might get away with just a fresh teflon coating and new bearings, maybe some minor repairs to the case.

Opinion @16GoManGoHC2 ?
