Sorry dumb question but does it matter which side up. The felt feeling side or the the slicker side with reinz writing ?

Tay-Tay

You'll do both. If you look you'll need one put on "upside down".

Super appreciate. Wanted to make sure before spaying a bit of adhesive to tack in place.

Btw anyone have torque spec.

Thanks

Think about using a thin coat of oil. I've been able to reuse my gaskets each of the four times I've removed my intake over the last seven years.

Thanks may try next time.

Well reason I pulled he intake was I had a leak at the 3rd runner. Now the last bolt closest to the firewall is stripped.

Do I have to pull the intake to helicoil or can I leave on?

Also any reccomenedations on which kit to get.

Thanks.

You're going to want to pull it..you don't want to drill & tap the hole through the intake - only the threaded hole in the cylinder head.

I presume you found it by now but ftr it's 15 ft-lbs

Don't know about helicoils but if you're buying online, you might want to consider timeserts instead. The downside is you usually can't get them in stores. But they are better - it's a solid insert instead of a coil so it won't come out.

I'll second the timeserts. They're a bit more pricey, but provide a much stronger and reliable repair.
If you go with a heli-coil, try to stay away from stainless steel ones. Stainless and aluminum do not get along with each other.

Oops I torqued the others to 30. I guess these gaskets are still good?

I will pull and use the timsert. Anyone have a link to the one I want.

Thanks.

This is why I keep a copy of the workshop manuals on my laptop and take it down to the garage to do work. Or for quick references this is a good link to keep bookmarked/copy and paste into a word document: http://www.lindseyracing.com/LR/Parts/TORQUESPEC.html

Thanks will keep handy.

I need to be more prepared. Used to do most work with my mechanic. But don't have time to get to the shop right now.

I'd use new ones if you torqued them to 30! You might be ok, but if they crack later you'll be kicking yourself when you have to pull the intake again.

I think they're M8x1.25 bolts but you better take it to a hardware store and check to be certain. Once you know the diameter and pitch just search online for the right ones. The kits come with around 5 inserts - make sure you are getting inserts of the right length. You cannot cut timeserts if they are too long, you have to buy a shorter one. But the inserts of various lengths are available separately from the toolkits.


The only other thing you need is a drill and a tap handle.

Here is a pretty good walkthrough of the entire process

Things to watch out for:

-Drill the hole straight. It's not too hard since you're just drilling out threads in an existing hole, but make sure you end up with a dead straight hole. Use a square or something as a visual guide if you're not used to doing this. If you do mess it up (don't) you may have a second shot to drill again and go with a thicker insert. But you want to avoid that route

-Make sure you tap the hole deeply enough for the insert you're using - otherwise you'll end up with an insert that's stuck in there without being flush (they're not that hard to remove, but still)

I don't know about this for sure, but I think I would use a tiny bit of gasket sealer between the gasket and the rim of the timesert. If you countersink the hole perfectly you might be ok.

Super

Super I may stop by fastnal and see if the can order.

Thanks for the detailed write up. Will order new gaskets.

Concerned about keeping drill straight. I guess I can go up incrementally in drill bits.

BTW - another helpfull suggestion is to convert to studs. That way if you have to take your intake on and off several times (likek we all do!) you are not wearing out the aluminum threads in the head. I use stainless studs with the nice internal allen drives and nylock nuts.

and - of course - as soon as you take the intake off stuff the ports with paper towels!!!!
