smog delete

Chris951 · October 29th, 2009, 12:29 AM

I deleted my smog when I changed my heads. I thought I had an exhaust leak at the headers but I changed my gaskets today and its the same. So, I felt around for air coming out and I found out that I forgot to plug the holes in the back of the heads haha. So tomorrow morning I'm gonna pick up some bolts from ACE. Anyone know the size bolt I should get?

The thread size in the head is 5/8-11.
The size of the thread in the Thermactor Plug (part # F4ZZ-6E086-A) is 5/16-18.
If you don't have the Thermactor Plugs in the heads, you can use a 5/8-11 x 3/4" long bolt from your local Hardware Store to plug the hole in the head. Most of the ones I have seen have had a 7/8" head on them.
I agree that using a bolt makes for a much cleaner look, if you can see them.
P.S. You might have to clean out the carbon deposits in the threads if your heads have been run with the Thermactor Tube previously hooked up and if everything was in working order.
Maybe this info. will help you out a little

The heads were cleaned up and rebuilt before I bought them. I remember looking and there no build up whatsoever so I'm not worrying about that. But thank you, that helped out alot. I'm gonna go pick up some bolts in the morning and hopefully get them in. Thanks again

Got it done. Sounds good now. Thanks Ryan.

One more question.. Can I ground the firewall ground and orange ground on a valve cover bolt?

no problem man and you could try a valve cover bolt although I wouldn't think it would be as good as a bolt directly into the block or one of the swaybar bolts.

anyone got pics of these holes in the back of the heads... that seems to b my problem to, someone had the pipe plugged, and my motor blew out the plug and now it sounds like crap. i didnt think the holes were threaded though in the back where the pipe goes in.i think this might also be the cause of my car revving at 3 grand for no reason..it never happend until it blew the plug out of the pipe, and then i shut the car off and restarted

Yeah, when my car had the holes unplugged it idled at like 1500 and acted like it had a vacuum leak and surged alot. If you feel on the back of the head towards the headers, there is a big hole. If yours are leaking, you will feel air coming out.

oscrfsh · November 1st, 2009, 10:13 PM

i found the pipe that is sposed to be there, somone just unscrewed the pipe by the valve cover. i was going to take it off because it is leaking, but where it screws in, and where the holes r where the air comes out r 2 diff places or am i wrong?
