No problems yet. Keep your fingers crossed. You're an exception to the rule. Are you using any sort of additive? ________________________________ Message 3 _____________________________________ Time: 03:23:51 PM PST US Subject: RotaxEngines-List: oozing valve covers From: "Roger Lee" Hi Guys, I'm doing a little survey. How many of you with a 912 ul, uls or 914 have one or more valve covers that ooze oil? Not necessarily a drip, but a little oozing so when you wipe the bottom of the cover it leaves oil on your finger. You may not even see it at times or if you have a cowling the high speed air coming through the cowling just makes a little mess on the belly of the plane. If you can let me know this info it is going to Rotax. Thanks, -------- Roger Lee Tucson, Az.

I read in the maintenance manual that at 200 hours: "Removal/assembly of the 2 carburetors for carburetor inspection (see chapter heavy MM 73-00-00 section 3.1)" Is this a complete carb tear-down as outlined in all of section 3 or only the assembly inspection outlined in section 3.1?

We can look at the carbs and detect most issues without complete disassembly. Check the bowl for dirt, look for leaks, feel sticky needles, etc. Are there any big fall-out-of-the-sky issues that will occur if we don't remove and fully disassemble the carbs at 200-hours? Disassembly may increase the probability of a failure. I think most of us simply checks our carbs, make needed fixes, but do not fully disassemble them at 200 hours.

They said they have a slab of glass that they will use as a flat surface to lay a piece of fine abrasive paper on and sand the mating surface of the valve cover. I have yet to try it.

Use a piece of 220 grit. Lay the cover flat and as you sand rotate it. It works some times and sometimes not at all. They now recommend 105 in/lbs for valve covers verses the old 90 in/lbs and instead of a dry "O" ring you can use some Loctite 518 or even some Loctite 5910. You don't need much. -------- Roger Lee Tucson, Az.
