    The famous 'money shift'. I assume you have some new lights on your dashboard that showed up about the same time?? See if you can check compression in your cylinders (easier said than done) but I bet you killed a few of them. Worked the valves and all that good stuff by bouncing your pistons off em'

    No I didn't get any new light no check engine no nothing I'm about to do a compression test to me it sounds like one of my valves is getting slapped by the position I may have bent a valve but no lights came on my dash that's the weird party may it be from the transmission ?

    Bummer, sorry to hear that. Can you upload a video of the motor sounds?

    It is kind of moot though as you will most likely be taking the motor out and tearing it down or replacing it.

    You said you were racing, by any chance did you get this pop up on your console?

    Post the vid. They can be loud on start up - rod knock doesn't go away when it warms up. You should have noticed a significant power loss too.
