Recieved 1st order from Macs today . After responsibility with fire department after work , rushed to garage to install manifold gasgets . Cleaned rust and grime off engine and manifolds I was ready till I looked at gasgets.
The gasgets are copper with the rings for exhaust ports.
The intake manifold has steel rings that won't fit the hole in gasgets
I see marks on gasgets . Do I need to cut intake holes to marks so steel rings fit through ??
Also the copper gasgets exhaust ports have rings on one side
Do these go into motor or manifold?
It's a 22 motor
Probably simple question but its mt 1st T
Personally, I would not use those. Get the copper "all in one" rings/glands. Yes, a set is somewhere around $37? or so, but they work great and worth every penny. Even makes single handed installation easier. You won't regret 'em.
Dallas..I looked up Macs part # for it...T3063HD, $35.25 in their new catalog. Incidentally, Snyders has the same set, T-3063-CR for $27.50. Pays to shop around!
These are one piece. 3 holes each.
The center intake holes don't have ring built in but exhaust does
I should know better . Should have asked you guys for opinion
I will install these and change later
They are a cheap change and sipmle
Do I need to cut hole larger for intake ?
If you really need to install these before getting the good ones you'll probably need to enlarge the hole. Then you run the risk of making the hole too big and sucking in more air than you need. I'd just wait till you get the better kind and be done with it.
The one-piece gaskets, without steel rings to support the exhaust manifold, will let it sag and warp. They're intended for use with a manifold that's already sagged and warped, but if it isn't already it will be. The expensive gaskets are fine, but so are the much cheaper separate steel rings and copper gaskets. If the manifolds and/or block have any rust pits, add hi-temp RTV.
It had fiber gaskets when when I bought it. They were junk to start with
I'll order the individual HD gaskets.
Just itching to drive her on maiden run.
Thanks for info!!!
I guess if I had read side note in macs I could have answered my question
Thanks again !
They don't have rings on the intakes because, when the exhausts are aligned the intakes will be in place. No need to cut them bigger.
