I just bought a used set of Berk HFCs, when i take them out of the box, i see one o2 sensor bungs is closed off with a bolt, ok, but im 99.99% sure its the wrong one. lol

I just wanna make sure this is backwords before i unscrew it and screw it into the shorter bung.

Also, i didnt receive any bolts or gaskets with them, can i reuse the stock bolts and gaskets, or should i buy new ones. IIRC when i installed my HKS the cats have bolts attached to them so i dont think ill be able to reuse those.

heres some pics:

 

hm... how did that happen? looks like it's in the wrong hole.

you need new gaskets, you old ones have a possibility of leaking... don't take that chance unless you don't care.

are you installing these yourself... or? and did you buy these from another member? looks used

 

Yeah i figured they were in the wrong hole.

Yes im installing these myself, just like everything else on my car pretty much.

Yep i bought them from a member on here who barely posts at all. He just happens to work at the shop i get my rims from, so i got a good price.


Ok, so i need new gaskets, but what about the bolts? Im sure i need a set for the HFC_Ypipe side, but what about the header to HFC side, do i need new bolts for that or are the bolts attached to the headers?


OH, also, when i move the bolt to the other hole, is it ok just to screw it in, or should i use some kind of sealant like loctite or something?

 

hm from what i hear this install is a b!tch... i'm getting my hfcs next week, but i thought FI or Berk had a set of install instructions... i have them in my email pm me your email so i can send them to you... yes i have them before i used to have hfcs but didn't get around to installing them and sold them... and look now i bought them again... lol

 

anyone else have any input?

 

you can reuse the gaskets, the oem mutli-layer steel gaskets are very high quality and can be reused several times,

oh ya change the bung bolt to the other hole

 

I have Berk HFCs on the way from the recent group buy. I was thinking about doing the install myself. I did the Tanabe Medallion (very simple), the XYZ-pipe (more difficult mainly because its hard to break the bolts loose without having the car on a lift). I like to do my own work but not if I'm getting in over my head. I have tools, jack stands, creeper. Anybody done it? Advice?

 

Apparently it's quite difficult, sometime like a 1,5-2hour job, also if your car is old, your bolts might be rusted on making it even harder. Just make sure you don't break your O2 sensors.

 

fi used my bolts that came with the car. as long as they don't break your OK. gaskets same thing. if they look good your ok.

 

I bought new gaskets and sandwich the gaskets with ultra copper rtv silicone.
It took me 3hrs to install mine. You gonna need a very long extension for the bolts from headers.

 

The extra bung can be used for A/F sensor or when you dyno if you want an accurate reading.

 

Just a tip. The top outside bolts for the cats you want to go in from the top with a long extension. They are a pain in the *** when you do them in your drive way on your back. Took me about 2.5-3 hours.

 

With all that stuff do you have the rattle hiss sound?

 

You're not talking about exhaust leak, are you? No rattles but I do have that annoying hissing sound when I let off the gas. Kinda like a BOV but not as cool. That hissing sound seems normal. There's already a thread about it.

 

Okay cool just asking!
