So my apologies on a slow update. I had been busy cleaning up the car and inspecting the front end over the weekend.
Finally got my car back Friday after they installed a new sandwich plate that Z1 got to me quickly. (Love those guys). That was $141 for diagnostics and (another) oil change. This doesn't include ordering another plate from Z1.
The engine is running, and seems to be holding her own. Something doesn't feel right but I think I've just been out of the car for a week.
As for the o rings that I requested. I never received the alleged USPS package. This is as of today 9/16. I specifically asked for them to be over night shipped. I was told the cut off was missed on Monday and they would ship Tuesday. It's a good thing I went another route and changed the plate. This is my only car and I couldn't afford to be without it for so long. I believe the not shipping the parts is poor customer service. It is on par with how I was treated concerning speaking with someone on the phone. I have been ignored when making requests to be contacted via phone and when I called the service rep was in a meeting and could not be reached.
As far as the part itself goes. Here is a picture of the plate post removal. As a note. We put the smaller oring and the sealant on it to check on the engine while waiting on proper replacement parts.
It appears to have a small counter sunk area. To me it doesn't seem to be as pronounced as the one in the video. The smaller o ring appears to have sealed it along with the high temp sealant.
Also, I have evidence it was a mis assembly. I was digging in my backup from my old iPhone and found the picture when I unboxed it and showed it to a friend of mine.
In this picture there appears to be a gap between the plate and the cap.
As I said before I did not altar the plate before install and I didn't know it was supposed to be flush as there is nothing to accompany the plate as far as directions or recommendations.
As for the concerns about what they're do for the engine, Mishimoto's philosophy seems to be ignore the comments concerning damage and when directly asked say "Mishimoto's warranty only covers Mishimoto parts."
As for this part it is being accepted as a return to amazon. I'm shocked they are doing it but I'm thankful for a company that does provide customer service.
Bottom line is I realize it's a performance part and there are risks involved but something like this is not acceptable to me. I feel it is feasible to expect a part to come to you properly assembled. Again this is coming from my background in automotive parts inspection as an engineer.
