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

abm89 · 03-07-2020, 01:59 PM

Did some data logging last night and the AFRs were all over the place. This morning I went and got some ultra copper RTV to seal the metal gaskets to my HFCs (and finally splurged on some tools, thanks ATT promotional card). Since my car is older and has had hardcore heat cycles from track work, those header flanges are warped.

I added a modest layer of RTV around the gasket opening (both sides) and put everything back together. Tomorrow we'll see if I actually fixed it.

More space in the new garage (slight flex but not really as there's nothing in it.)

And here you can see obvious signs of leakage. Both the driver and passenger sides weren't doing ****:

And now it's curing for the rest of the day:

Sounds like a lovely excuse for new headers/test pipes!

I just bought the HFCs because i was sick of the smell lol. i'll eventually go full Motordyne Headers but I'll wait until an engine rebuild is necessary to do that!

If you're N/A. That might be never, unless your galley gaskets lets go and you don't catch it in time.
