Yup. I get that 4th, 5th, and 6th between ~3k and ~4.5k. 5k+ picks up a bunch, and 1st through 3rd have enough gearing to overcome it, but yeah, under 5k my power is simply gone.
I've considered video'ing it, but there isn't an easy way to accomplish that, and all people will say is "get a compression test".

Might be worth a shot. but what do I know.

My compression was scored at 7.0s and 7.1s about 6 weeks ago, and my power has been steadily dropping since December when my cat failed. I'm convinced it's simple loss of compression, caused by a critical cat failure, probably overstressing the seals. When I got the compression test 6 weeks ago, they said "sorry, it does pass, we tried everything we can to get it to fail, and it just barely passed every test.", and when I said, "so bring it back in a few months?", they said "yep!"
The ONLY other possibility is a vacuum leak, but nothing has ever been found, and with those compression numbers....

Your thinking is right on, I had the same for a while, but we checked the valves with a hand air pump after disassembling the UIM to get to them, and they operate perfectly fine.

Hmmmm I vote you accidentally suck up 3 ounces of 20w50 per service port and keep it idling for 30 mins that should give you some decent carbon buildup.
i see what you did there DC

Hehe, yeah, they have no problem installing various mods like the BHR ignition, REmedy water pump, thermostat...even the Mazmart Oil Pressure increase pellet, which kinda shocked me. The 2 mechanics that are the only ones that touch 8s are both rotorheads, one of them currently owning a 7 I think, the other used to. And the service advisor is intelligent and recognizes the reality of stuff.
The flip side is they were the ones that destroyed the 8 a few weeks ago during post-engine replacement shakedown, when they reused the fuel line and it came free, starting an engine bay fire.
But then, I can trust that they won't make that mistake a second time
It's 90 minutes away, I pass...6? dealerships to get there.

I've done all my own maintenance recognizing that they may refuse to cover it in the end, and since I've been through a 3 year legal battle over warranty coverage before (with Toyota), I know my rights and responsibilities, and their rights and responsibilities, so I know that self maintenance can't be held against me legally.
But if it comes down to paying for a court battle vs paying to get a BHR engine rebuild, I'll take the rebuild. It's better anyway

No worries. I don't have your phone number
But yeah, one reason I am trying to get it taken care of now. It is the only remaining reason why I would have to cancel on the Sevenstock trip.

Uh, no. I refuse to defraud Mazda. If my compression fails, it fails, and if they will cover it then I go that route. If they won't, then I get a BHR rebuild.
