SOUNDS LIKE I SHOULD  DO ANOTHER RUN AND MAKE MORE OF THE THICKER GASKETS AND TE PLATE FOR TH REAR OF THE PAN. IF I RECIEVED INTEREST  NEED COMITMENT. ON 5 KITS BEFOR I START.   CT1940@SHAW.CA.

The oil pan gasket has arrived.  Plans are to first just lay it on a pan and check the overall dimensions.  Once that is performed, then install the gasket on the 312 dyno mule and run the engine during the Christmas holidays.

Ted, I received the prototype silicone gasket and sent it USPS to your shop Friday Dec. 1st so shoud arrive one day this week. The gasket does look very good, thanks again, JEFF..........

Thanks Ted for your offer and time. I agree a wet run on the dyno would be a better test than a visual and would be worth the wait.  Winter is around the corner in Michigan so by the time I can install it on my truck I'm afraid there won't be much apportunity to put on miles.  I have confidence this Si gasket should be a good thing....

If all I need to do is examine the gasket for a non-installed evaluation, I can do that.  That’s the easy part.  Actually testing the fit of that gasket on an engine and then running that engine in a variety of conditions would be the more difficult part.  While I can do that on the dyno mule, it would take some time to determine if and when a failure point occurs.  The dyno mule is scheduled to go back on the dyno late this year for some testing of parts in early January.  That would be an opportune time to also run that gasket on the 312 dyno mule.
 
A more suitable test would be for someone to actually put it on their daily driver Y for a period of time.  That daily driver ideally needs to be one that does not have any oil leaks before installing the gasket just to ensure that any leaks that show up during the test were not because of a pre-existing problem.

Received word today a silicone gasket prototype has been produced. They need an evaluation as to form, fit etc. before production.  Ted, would you have time to evaluate this gasket? I could send it to you after the Thanksgiving holiday.  Your valuable input would be very much appreciated. Thanks, JEFF........

the oil seal retainer is a rough area as ted said.i always put some gook os some kind here before installing the pan.to get a leak here the first think your going to think is rear seal.

Ah-ha!  Thanks for the heads up and memory jogger.  I totally forgot about the Y-block silicone gasket as life got in the way of things with me this summer. I'll try contacting the folks at Real Gasket TN next week to find out if they are still willing to produce a silicone gasket for our engines.
