I removed my exhaust manifold and reused the gasket. I coated it with Hondabond HT, the gray stuff. It says high temp and is rated for 600 degrees so thought it would be OK to use for that. I took a better look at the tube today and don't see anything about it being O2 sensor safe. Is it ? I hope, I hope, I hope.
wow...
ya dont use any kind of sealant for exhaust gaskets. that shit is gunna burn right up.
Oops .. will that take out the O2 sensor?
I've had no issues using high temp sealant on the exhaust gasket between the head & manifold, but i have between the manifold & downpipe. you should be fine installing the o2 sensor without any sealant at all.
Well, so far so good. I fired it up and got the usual smoke from getting a little oil on the manifold and maybe some from the Hondabond. After all that burned off I drove it around and runs OK. Thanks for the replies. I'll probably put a new O2 sensor in it after I get a few hundred miles on it. It hasn't been change for quite a while.
