I have a new to me '78 M20J. During the pre-buy the mechanic pointed out that there was a foam filler piece missing between the duct and the oil cooler on one side. The oil temps are fine, but I would like to replace the filler piece. I looked in the Mooney Parts Manual and it is listed as part no. 620017-000 but when I google that number the only hit is Lasar and they are out.
My question is whether there is generic foam tape that is suitable for this application and if so the brand/type. It seems that whatever is used should be suitable for a higher temp environment and that just a generic brand from Home Depot is not appropriate.
Thanks. Appreciate any help or advice.
