Thanks Garrett!
I'm not done with Certified Motors, LLC Tampa Florida and Joe the owner. But before I start this I really need to know what my damages are. Just a few weeks and this side of it will be known although I must admit waiting to contact him has been difficult for me. And I do know some attorneys in Tampa from my work there so getting help if needed should not be a problem. I also have the state dealer complaint form filled out and on my desk but I doubt they will do anything since it was an out of state purchase? Thanks everyone.

Ok, well pretty good news. Motor is out and nothing external to the crank, caps or rods so although not apart yet builder says 99% sure just bearings. Turns over fine still. The heads are fine but we are doing new guides and a valve job, the old while we are there...... The rest of the big list is:
Mahle pistons
Total seal rings
Clevite bearings
Mill the head .020
Katech 116 cam
New oil pump
Bla bla bla.......$
Have no idea what cam is in it now as it's inscribed with all kinds of hand written jiberish: 3728r/ 373r BHR113+2 D6547-14
Has a Katech dual plate clutch so will see condition. New throw out bearing to be done.
So just what I wanted for my new car, a new motor....not When I got it the motor dynoed at 537 RWH and with the heads shaved Patrick says he gets around 545 RWH so I'm fine with that. I've got AR long tube headers, polished throttle body and a Halltech Killer Bee already to go with the higher compression. Not trying to make a monster(already have 2 race cars) just will do some light track days, hamburger cruises and want this thing to go a lot of miles before this again

Pistons are the only part of the balanced assembly that are not forged and a lot of times they get damaged removing the wrist pins. Just insurance. Long term plan is the same for when I bought the car. My best friend and I vintage race Corvette's and own Porsche's. He bought a new GT3 RS and wants to do some track days and asked me to come along. So I bought this to go with him. Lets see what I can do with my Z against a really expensive Porsche. My latest challenge to myself, will see.

We do and I fell very blessed to be racing with my college roommate, and my 35 year best friend. The older I get the more appreciative I am. Thanks
Got the estimate for the engine build and I will definitely be contacting the dealer once the job is complete and we know the exact failure.

An update to my motor rebuild thread now..... It seems I caught the problem very early so no major damage in the engine. #1 main bearing looks like the culprit for low oil pressure and another main and a rod bearing looked pretty toasty at the engine shop today. These bearing issues were not immediate and the builder and I agree it looks like over heating at some point along with poor oil change/type characteristics. When I got the car the radiator fan module plug was burned and the fans were not running which couldn't have helped either with the car in a warm weather city. So it looks like stupid owner syndrome kind of stuff. The good news is the block, rods and crank are fine.
This is not going as fast as I would like but I should be back in the car in about 3-4 weeks it seems to me. So Merry Christmas to me for something I didn't want......kind of like ugly socks but better, as once it's all buttoned up I do not have to see any of it again

Should be a pretty easy fix. Are you going to replace the bare minimum or build it up a bit? What's your parts list look like? What bearings you going with?

Sure, an easy $11K +. Not what I call fun. I went thru some of the parts above. Clevite bearings with a shimmed stock oil pump.

Glad you found the problem, somewhat surprised at the bill for diagnosing and just doing replacement/repair of the modest damage. For $10K you should be able to get a nicely built (non-LS7) engine installed. If you did a build then easy to get there.

Well $2,500 is to R&R the motor. When you go down the list it makes sense. Not good but sense. And I never felt comfortable with the motor and passed on a trip in it with the wife. I was right and avoided a big disaster if my wife had been involved, if you know what I mean.

We are doing a lot more than just fixing the damage. Basically a new motor, heads gone completely thru new seats and guides, new oil system including lines and cooler and all the "while your in there things" . I thought about an LS3 but that's not what I bought the car for and decided against it.

You're a race car guy...you know the benefits of a nice radiator and proper oil temps.

For the price of a new OE oil cooler and lines, you might as well upgrade that OE radiator with a Dewitt's w/integrated oil cooler for about the same money. Now you get a better constructed radiator (larger core, aluminum end tanks), better cooling, and you get the benefit of getting rid of the OE oil cooler that is overkill for the street. The integrated oil cooler in the Dewitt's will get oil temps up much quicker, and keep them where they need to be. I remedied the "cold oil" issue on my '09 a couple years back in a similar fashion, but used OE ZR1 parts.
