What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

Gooch · 05-10-2020, 12:37 AM

Been tuning my stock block BP kit build with Seb the last few days. Things were great up until today, a light tapping coming from somewhere. If I didn’t know any better, I’d say it is an exhaust leak. Going to take everything apart tomorrow.. praying it’s not from one of the headers.

I hope you find the issue and it is an easy fix!

Spent most of the weekend crawling around under the car...I remember doing this 10 years ago like it was nothing, but now I need a chiro appointment

Stock clutch only had 40K miles on it, but the car picked up a weird, sometimes violet, vibration on decel. Turns out the dual mass flywheel almost became two actual pieces.

Everything’s smooth now, though

Any pic's of the old flywheel?

I’ll grab a few tomorrow, but it doesn’t look bad until you “play” with it. With just hand manipulation I could get it to move a LOT.

Like I said, it doesn’t really look all that bad, but I can spin it about 25-ish degrees by hand and get around 3/16” of deflection. I don’t know if that’s within factory limits, but I’ve been trying in earnest to replicate the vibration I felt before and everything’s smooth like butter.

That second pic is not normal.

Turned out to be the passenger side header flange to where the cat would be. Replaced both gaskets for good measure; the original was cooked in two different places. All is well now. And fixed two rattles, one was my exhaust hitting the W brace and the other was my BOV rubbing against one of my horns. What a machine.

That reminds me, I never reinstalled that horn, only running the one.

Dewla dezigns air guide has the horn relocated to the front fastener for the passenger side headlight.
