OK folks, I have narrowed down my vacuum leak problem on my '65 Mustang's 289. It seems to be a faulty seal between the intake manifold and the block/heads. I am going to do my first intake manifold gasket replacement VERY soon. Any tips/warnings/prayers you experienced folks would like to share to make my job easier? I am using a Fel-Pro gasket set, by the way.*andy* ([email protected])

Andy,
One trick that I've used for years, and I feel that is has been very successful in gasket alignment. The intake manifold bolts are 5/16-18 threads, get four extra long bolts at least three to four inches long and cut the heads off, or get some all thread rod. Once you have the intake gaskets in place, screw the headless bolts into the heads, two per side. This way you will have a guide to lower the intake manifold onto and the chances of sliding or moving a gasket is reduced. After the intake is lowered just unscrew the studs and replace with regular bolts.  Good luckMike

Whats your guys thoughts on the cork gaskets that bridge across the front and back of the block? Use 'em or toss em for just RTV?

well, considering last time I had to pull the intake to remove the leaking cork gasket, clean it and rtv the hell out of it...
you can guess my advice...
give yourself a decent amount of rtv, about a quarter inch thick in replacement of the cork, make sure its a smooth fit to the intake gaskets, let it get fairly hard before you put on the intake, but still sticky, say give it 30 minutes or so.
never had a problem when I've done that.
the damn cork, however, always leaks on mine...[This message has been edited by 74merc (edited 04-19-2001).]

Me too! Use form-a-gasket and toss the cork (or rubber).  SteveW p.s. The studs work great for alignment.

use super weatherstrip adhesive to hold the manifold to head gaskets in place. RTV in place of the cork end gaskets and torque in the proper sequence for a perfect seal. Good Luck, Fred.

I used the end cork on mine and have had no problems. I did use and adhesive between the block and cork gasket to hold it in place. Most leaks there occur because the gasket "sqeezes" out when torquing the intake down. Then I used a bead of Blue RTV between the cork and intake making sure to put extra at the four corners of the intake. Also, I had to trim my end cork gaskets to get a good fit before I installed them. Just my two cents ------------------
