Valve cover gaskets 2018-& older

I used to have a 2005 Patrol, then I bought and currently own a 2010 Gear Up. I have found that when I remove the valve covers to do valve and head torque maintenance, that most times I have to replace the valve cover gaskets. I find the gaskets get brittle, especially the center section that the threaded rod holder goes through. I feel it’s best to cut that center section off of the gasket and just rely on the two pin holders that line up the gasket to the head. I can’t say how many times I’ve found those center gasket sections broken off the gasket and laying in the valve cover. I even use the,”Real gaskets of Tennessee “ brand which is supposed to be reuseable. I may get a couple of uses out of those but even they become brittle and fall apart. What have I learned? Alaways have a spare set of new valve cover gaskets on hand especially if you have a head torque and valve adjustment coming up. Remember snug is good enough and never like the mighty Hurcules...

I switched mine out with silicone gaskets 5 or 6 years ago, no problems reusing them. Trick is to wipe the oil off them each time the valve cover is off. https://www.heindlengineering.com/Onlin ... covers.jpg

Chao2, Those gaskets you linked are the,”Real Gaskets of Tennessee” brand. They come in orange or black. Real gaskets stand behind their product. They recommend making sure all mating surfaces are completely dry and free of oil. Never use any kind of sealer.

Plus 1 on the Real Gaskets. Been using them on all my bikes and for years in aviation.

Jim Pettiti (rip) of Racewayservices, Salem OR, used to clip off the center conector because it tends to pull the seal into the valve cover and cause a leak.

I switched to silicone gaskets on the Retro over 60K ago, no problems, last 20 to 30K so far, but I think the Retro valve cover is kinder to he gaskets. Tried a set of silicone gaskets on the new gear up, we'll just say the torque spec in the manual did that gasket in quick, then did same to a new stock one. Like Marty said "snug is good enough and never like the mighty Hercules", dealer and I both kinda figured under 10 ft-lbs (snug) not 17 (more than just snug) is more like it. So far, so good. Oil pan is 7 ft-lbs, so that may be enough for the 4 bolts on the new valve cover methinks.

I switched to the new style and the leak like CRAZY on my 2011. Maybe something is different on the new EFI that they seal better. I have tried three times, and still no Bueno.

Agree with clipping. Have had the same problem. I use a formatex gasket adhesive on the valve cover as a holder. Never leaked but a bit ofd a PIA to get off (laquer thinner) next time you change them.

Switched to the silicon gaskets and no further leeks. +30 on the surfaces needing to be clean of oil and dry (real pain as there is always a smidge of oil lucking ready to ooz out). I do use a torque wrench but I'm getting a feel for the amount of pressure.

I think that's the trick with the silicone gaskets. The torque is very light.

So I see a lot of positive reviews on the silicone gaskets versus the paper gaskets. I also see people mentioning to make sure there is no oil on them or the head before installing them. Other than wiping off the oil with a shop rag, do you use some type of oil cleaner or is wiping clean good enough? I noticed that the gasket on my current bike must have been torqued on too hard by the previous owner because the gasket is pushed out and has a slight leak(see pic). Is this what the gasket looks like if it is over torqued? Even though the leak isn't too bad (not even dripping on the floor), I thought it would still be a good idea to replace the gasket.

I use acetone to dry the surfaces. before that I also clean out the oil return hole otherwise Murphy's Law brings a drop of oil just before you put on the gasket.
