There has to be a trick. ;-)

I've pulled and put on my new intake (edlebrock performer)
about 7 times now with no luck. I have used new gaskets.
Up and until yesterday it has always leaked due to a poor
seal. I tried again yesterday and this time the cork slips
out when I get any kind of pressure on the bolts. I am
pretty close to throwing the cork out and just using RTV
all the way around.

Any helpful tips would be appreciated!

Thanks,
Wil

Wil,

When installing a new intake, the FIRST thing most people do is throw away
those cork ends.... RTV is the method of choice....

Good Luck!
Keith

Wil, that's what I've done. Toss the cork from the
front and rear of the block and just use RTV.

((side note, I found I got a better gasket match to my
intake, a motorsports performer, when I used a gasket set
for a 351W HO truck application)) This was on a '69 351.

Good Luck
Randy

There are 3 things you can do to help seal the ends of your intake.
1/ Glue the cork down using weather-strip adhesive
2/ Use RTV instead of the cork
3/ Guide the intake down straight by using studs with the heads cutoff as a
guide

If you use the cork end seals, you must glue them and wait for it to dry. I
have also used sealer with good results. Also try cutting off two old bolts
to use as alignment studs, helps seating the manifold straight a lot easier.
Good luck.

Just to confirm, I installed a Weiand intake on my 302. Their
installation instructions specify to use RTV, and to get rid of the cork
thingy...

I like to use Ultra Blue for anything that is direct contact with hot oil.
It seems to be the most oil resistant.

One other thing on the whole thread. I have always tossed the cork end
seals when installing an intake, but an old time mechanic lives next door.
He has told me to toss them when putting an aluminum intake on an engine
with iron heads, but it was ok to use them when putting a cast intake back
on. The cast intake has the same expansion rate as the heads. Don't kknow
about his theory, but it seems reasonable to me.

Later,

David Cole

I like the black best, but the blue works.

I like the high-heat permatex ultra copper myself.... don't even use the
plastic tip, just open up the end of the tube and lay a nice 1/4-3/8" bead
right on the block where the intake sits. carefully drop the intake square
on it, using the cut-off bolts as guide-studs as suggested earlier.

Well, every one has there favorites. All of them works well, It's just a
matter of personnel preferences. My advice go to the store, buy the first one
you see, see if you like it. If not, next time use something else. After your
5th or 6th motor you will find what works best for you.

P. S I had motor problems on my LTD that ended up being a mismachined cam,
and I had the intake and front cover off about 5 times in 2 weeks. I used
blue, black, even some gray that is OEM for Mazda that I got from work. It
all worked. I just used what I could get in short notice.

Thank you for all of the responses. I took everyone's
advice and threw out the cork and just used RTV. NO
leaks as of yet!!


Thanks again!
Wil - glad to be back on the road.

I vote for black rtv. I had and old Oldsmobile and they use valleypan
gaskets. The felpro kit comes with black rtv for sealing the end corners,
so it must be okay. I've always gone with the rule: black for contact with
oil, and blue for contact with water (water pumps).

I used the blue for this application.

What I think: the clear stuff is more for water passage applications
(thermostat housing, etc...), black seems to cure into a stiffer gasket,
I used it on expansion cups, etc... Blue seems to stay way flexible, and
resists well to all sort of stuff. Sounds good to me for the intake
manifold.

This is just from what I have seen building ONE engine, and reading tons
of silicone RTV packages (spent quite some time in the store, trying to
figure out if I was stupid or if there really was no difference between
many of these :-) ).
So take this with a grain of salt.
