Literally just put it in. Will report back.
Looks at workbench and sees brass washer.
dumbass
oh well.
Uh oh - forgot the washer for the spacer?
You think it's going to leak?
This is pretty newb but what would be the most obvious sign if the spacer or a vband clamp is leaking?
That's what I thought but just wanted to make sure I wasn't missing any other signs
If I do a cold start, and put my hand near the o2 spacer, should I be able to feel any escaping gas (if there is a leak)?
I wouldn't even try that. The DP gets very hot very fast. If you can't see exhaust with a flashlight down there then there is likely no leak.
If I can't see any exhaust gasses with a flashlight, then there no leak, correct?
Didn't know you could visually see them that way.
Definitely. When I installed my DP I didn't have a 6mm allen socket, just a key. Good luck tightening that vband with a key. It smoked pretty good until I could crank it down.
