big block intake swap gasket problems.

[468cibu]

swapped over to weiand stealth 8018 intake from P.P. Hurricane. I ordered felpro 1275 gasket as advised from weiand"s instructions. Ports on gaskets not even close to sealing. I could see port opening through extra bolt hole above runners. Figured gasket slipped< so ordered another 1275 gasket set. Same problem. I know there was no slip this time. I paid close attention and rtv around water ports held it beautifully. Anyway. Took intake to ap store and matched up perfect with ultraseal 5828 gasket. So now the motor is buttoned up, everything sealed perfect. No internal leaks. Problem??? Gasket material protruding past manifold appears water wicked. Mr.Gasket says the gasket should not absorb water. Motor is running better than ever. Do you think I should just run it and see if a heat cycle or two cures the moisture in the gasket or should I bite the bullet and replace yet another gasket set. This time with a felpro equivalent. Sorry for being long winded but wanted to be as clear as possible. Thankyou for any insight.

Drove the car around a bit yesterday, even hit a local cruise night. So far so good. Checked gasket, seems to be drying out nicely. Maybe just needs a few heat cycles to set up? [-o< Also checked torque on bolts. They seem to be holding fine as well.

If you are worried about it go to Autozone rent (free) there radiator pressure tester.

This way you will know for sure it is sealed.

Before you start dumping coolant into the oil and wipe a bearing.


The one Autozone has will fit right onto the raditor neck.

Advance Auto has one too but you need a rubber adapter to use it.
