As an adjunct repair option to the replacement of the AIP Hood Cowling Seal mentioned in this Thread:

...and covered in this linked (and attached) TSB Repair PDF...

… THIS Weatherstripping offer on eBay has additional possibilities in solving the problem involving the Rain Water Flooding of the Upper areas on the GM 4.2L Engines and Coil Packs causing Engine Mis-Fires and Cracked Spark Plug Porcelain Insulators.

This otherwise Hard To Find Hollow “D” Shaped Weatherstripping is available at a Bargain Price of $8.95 (S&H Included) for a 4 Meter Length:

Another option is to duplicate what the factory solution was. Attach regular medium or high density foam rubber weatherstripping beneath the D section of the original seal. This will lift it higher and seal better to the hood.
Probably a good idea to do this even if you have no issues - keep excess water out of the engine compartment.

I had the stuff sitting on the shelf. Here's how it looks:

Normally the original rubber seal is pushed down the "step" and reduces how much sealing pressure can be applied - apparently it can be inadequate. The original rubber seal now rests on the weatherstrip and increases the seal pressure.
There is a problem with this whole arrangement. The entire seal forms a "bowl" where water collects in the middle - right where the spark plugs are. There should have been a drain or different shape to this area so water doesn't collect.

Another option: apply contact cement to the bottom of the original seal and plastic cowl underneath and make a positive seal between the two. That should also keep the water from flowing down into the engine.

@Mektek , you should do an actual writeup in the tech section as this could be good info for someone. In here, it will disappear after 6 months.
