Working on reinstalling the intake and exhaust tubes on my engine after performing the wobble test and ensuring that I don't have a sticking valve. That story here: http://www.vansairforce.com/community/showthread.php?t=151957
I have 4 of the blue fluorosilicone intake gaskets that I never installed due to the reports of low torque required to keep them from squeezing out and due to Vlad's reports and pics of them after hundereds of hours. Botom line is I don't plan to use them.... If anyone wants them, drop me a note.
There are reports here of people having good success using the copper 75118 gaskets on the intakes including Vlad which is likely the king of RV hours flown per year.
Originally my engine had the spiral wound blow proof gaskets and when I removed the exhaust I did find some slight evidence that they were leaking a bit around the flange. All the grey haired mechanics I talk to say "Blow proof won't blow out but they will leak!"
So I am possibly looking to replace both intake and exhaust gaskets with 75118 solid copper gaskets. (update: Since people I trust have spoken, I will be reinstalling the exhaust with blow proof spiral wound gaskets.)
Lycoming SI 1204D states that when using the 75118 gaskets on the exhaust that they must be used in pairs, nested with each other with the bead towards the exhaust.
For those using 75118 gaskets on the intakes, do you use 1 or 2 of them and which way should the bead be installed?
