 |
|
What's the best way to match port the intake manifold gasket?
I bolted the gasket to the manifold and used a sanding drum on a dremel until I hit metal.
Is there a better way?

Damn i never even thought of doing it like that  The only thing i could think of would be an exacto knife. But i think your way sounds pretty darn good to me. Im sure that would produce a nice consistent cut on the gasket and not look too butchered up. |

are you using metal gaskets? I used to use the old thick paper ones and an exacto using nuts and washers to keep it from moving while cutting. I would keep that one as the original for a template to cut the others when needed.

There was an article in Volksworld a while back that suggested fitting the gasket and tapping it with, IIRC  the handle of a screwdriver to make an impression
then cut the gasket with a craft knife. |

I'm using the Berg extra wide paper gaskets.

That's how I do mine, unless the engine is assembled - then I use an exacto knife...

I have used Loctite 518 flange sealant on my manifolds for a couple
of years now, just a thin layer and manifolds straight onto the heads.
I have never had a leak or had a nut come loose from vibration even
in off road cars. I read about this over on the Cal-Look and it worked
great, I use it on my oil pumps to case also with no gasket . It fools
you by looking like it never dries around the edges but it is good and
sealed between the metal |

what about when you remove the manifolds and reinstall? Do you have to clean it off before reapplying and reinstalling?

Yea, it comes off pretty easy with a blade and Berrymans B12 will get
it off when applies directly onto it, I have never had the B12 affect it
when sprayed on it in the assembled condition. |

'Old School', ha. 1940's era aircraft engines didn't use a gasket on the carburetor to manifold connection. The two surfaces are machined and assembled using a none hardening, fuel resistant sealer and a piece of sewing thread. The manifolds are laid out so that the thread can be run from stud to stud, and be centered on the mating portion of the flange.
The thread trick would be tuff with the VW manifold design. |

Sanding drums will clog up quickly w/ aluminum. Use a HSS or carbide burr to port all the way to the outline if that is all you need. WD-40 for lube is okay. I use tallow sticks (used in bandsawing).
Didn't the heads get ported with the manifolds?
If the surfaces are machined perfectly flat and no burs, sure you can install naked. Or you can use a skinny paper like an oilpump cover gasket to seal the manifolds.
Hell..tranny intermediate carriers only has the skinny paper gasket. That thing is so flimsy, it will rip if you looked at it long enough.  |

Nick,
I used a sanding drum since it will easily cut the gasket but not chew up the aluminum when it hits the manifold.
The manifolds were match ported to the heads.
