There is no valid reason to put on a gasket dry. I have yet to replace ANY paper gasket on ANY airplane that I've installed them on with a light coat of Titeseal. Period!

700 hours on the engine
 
Set of gaskets started leaking again after almost 550 hours on them.
The procedure is simple and doesn't take much time.






Scrape old paper, clean, degrease. I left light coat of titeseal on one old gasket and it was very easy to remove RocketBob was right. The intake hoses are kind of hard. Do they have a lifespan?







Innards of cylinders get cleaned up lots of lead there.







Plugs cleaned and regapped.







Good to go. Vroom! Engine works like a Swiss clock :D

Across many forums and this one included....plugs gapped EVERY 50 hours to 0.016-0.018" and the inlet gaskets........wel they seem to last 250 hours :mad: And that is sad to say.

Last weekend I found two intake leaks on a RV7 that had 140 hrs.

If it helps the red SUPERIOR gaskets seem to last longer.

Glad you are onto these things! :)

David do you know where to order red SUPERIOR gaskets from? ACS seems don't have them. Also I would appreciate part ## on intake hoses. I would like to replace them they became very hard and edges are crumbling. O-320 here :)

Interesting.
 
We built my IO-360-A1A in 2006, it has 1100+hours now, runs beautifully, never messed with intake gaskets and has never given any signs of an intake leak.

Only 100LL I assume? :)

Yes mostly 100LL however recently it has been mostly pure 92. Been doing the MOGAS in the right tank, 100LL in the left tank thing with great results.

Do you suspect it?s the MOGAS that is causing this problem?

I burn a lot of ethanol laced premium gas straight from the pump. I suspect it affects certain rubber parts and gaskets. I don't have access to pure 92.

... aaand here we go again :D





I thought Aero-in-stock have Superior gaskets but they sent me regular. So far I tried three different supplies of intake gaskets. All leak after couple hundred hours. Or maybe I install them wrong.


I also bought and replaced intake hoses. They look very funny totally deformed but didn't leak.


















All new.
