I am in the process of doing a heads and cam swap and was planning on removing the AIR sys. in my car. I have AS&M headers and am going to need to block off the AIR ports. What size bolts do I need to plug the header holes? All i can seem to find is that it might be a M22 oil pan drain plug. If that is it where can you get them? I've done a search and have not found any sure answers for my question. Thanks for your help!

 

yea its a m22 drain plug.i got mine at a local auto parts store.u might have to order it though b/c its a pretty big plug.

 

Hey, thanks! I thought that it was an M22 but wasn't sure. I tried all of the local parts stores today and the bigest anyone had was a M20 The dealership had one but they wanted $15 and some change for one of them! I guess I'll have to do some more searching. Thanks again.

 

Dunno how the AS&M headers are but for my SLP's I need 5/8ths brass caps for them.

 

96-97 has different thread size. I used M18 on my FLPs.

 

i had AS&M headers/RKsport headers i used an M22 to block off the AIR plugs, bought them at the local auto parts store, for a few dollars each...

I guess that tomorrow I'll have to find out which auto parts store can order them for me. Did any of you use any kind of sealant along with the M22's or do you not need to???

 

I put a washer under the drain plug.

I had already taken a look at your pic on another thread and was planning on doing the same thing on mine. Thanks for the pic

 

i used antisieze so i could remove the easy if i needed to.
i had no problems with them leaking.

No prob. I was once in your shoes. Just want to repay what I have learnt through helping others.

 

Hey Jesse thanks for your reply on both of my threads. I was just wondering because the directions for the ARP bolts that I bought say to torque to 85 ft. lbs. if no sealant is used and 65 ft lbs if ARP sealant is used. Is their sealant any better than the stuff at the autoparts store???

 

I torque mine's at 70 ft-lbs if I can remember.

 

i torqued my to 65lbs and used permatex sealant. it worked fine.
be sure to torque them in 3 steps....
i think i spent 1 hour each on torquing the heads.
but im slow

Thanks again...but was that in your car or your lawnmower??
