Front "China wall" sealing issue on SBM

RustyRatRod said

Using cork with RTV is not a good idea. The RTV will act as a lubricant and the cork will slide out from under the intake as you torque it down. If you use anything use something like 3M yellow weatherstrip adhesive and glue the cork to the block with nothing on top of the cork. You'll also want to put a small dab of RTV in each corner where the heads meet the ends of the china walls.

Cat had a green/yellow gasket adhesive similar to the yellow weatherstrip adhesive. Brush on the gaskt and the metal and let sit for a couple of minutes. You better get the positioning correct because at contact it stuck like **** to a diaper. Used a lot on final drive covers and oil pans. This was before the 3M buffing disks. What a beggar to get clean with a scraper. Final drive covers had a few dowels and required puller bolts to get them off.
