eman1200 Posted August 8, 2018 Report Share Posted August 8, 2018 any concerns firing up the engine with the side and top cowl off? more specifically, I'm just a little concerned with the lower portion of the front cowl and if that is strong enough not to wobble too much and potentially cause damage. I have to imagine everyone does this post oil change. thanks! Quote Link to comment Share on other sites More sharing options...

The wind will blow them around, scratch your paint and you will be sad. 2 Quote Link to comment Share on other sites More sharing options...
jaylw314 Posted August 8, 2018 Report Share Posted August 8, 2018 You're cowl is different than my J cowl, but when I had my prop dynamically balanced, the A&P just used safety wire and zip ties to hold down any suspect areas of the cowling, especially the parts near the spinner. 1 Quote Link to comment Share on other sites More sharing options...
eman1200 Posted August 8, 2018 Author Report Share Posted August 8, 2018 I did a pretty thorough pre-check, then ran it for probably less than 3 minutes. Basically just to check for leaks. Re-cowl’d but lunch break is over so I’ll do a few laps in the pattern tonight. Thanks! Quote Link to comment Share on other sites More sharing options...

Yetti Posted August 9, 2018 Report Share Posted August 9, 2018 Well if you are doing it to check for leaks, there will be one, it is a Lycoming after all. Just marking it's spot. 1 Quote Link to comment Share on other sites More sharing options...

Seriously, I have a leak (somewhere low) and it’s not enough to affect my usage too much, I have looked for, I’ve ask mechanics about it, don’t know where it’s coming from. It ends up on the nose gear, and bottom of course. Quote Link to comment Share on other sites More sharing options...

bradp Posted August 9, 2018 Report Share Posted August 9, 2018 After I replaced my Crank gasket my engine is only getting a leak after i spill oil during a change ... at least for now. Quote Link to comment Share on other sites More sharing options...

How did you go about finding the source of the leak? I assume that required a tear down. Quote Link to comment Share on other sites More sharing options...
Yetti Posted August 10, 2018 Report Share Posted August 10, 2018 How old is your engine rebuild? There are a couple places to check. The oil return lines from the Valve cover gaskets. The dipstick tube gasket. The engine halves. The cylinders. 1 Quote Link to comment Share on other sites More sharing options...

The dipstick tube gasket. The engine halves. The cylinders. Not a rebuild, 2200 hrs SNEW, which is why mechanics usually recommend an overhaul. Top half is dry including all cylinders , it’s somewhere down low. Didn’t think about the dipstick tube gasket, what about where the oil return lines opposite end?

Mine was pretty simple - oil collecting on the starter and starter adapter. Tracked it up to the crank seal. Prop needs to come off but it’s a one hour job and a $30 seal once the area is exposed. 1 Quote Link to comment Share on other sites More sharing options...
Yetti Posted August 10, 2018 Report Share Posted August 10, 2018 On our engines the aluminum tube that come off the rocker arm area is connected to the case haves with with rubber hose and 2 clamps. The original were thumb screw, some people replace with a hex head so they can put a flexible shaft socket drive to tighten up. Most of the thumb screws if positioned right way can be tightened with the right size socket. I think it is a 1/2 or 7/16. They were designed for thumb pressure/hand tight so don't go crazy. Usually you can take a flashlight and see where they have a drip on them after sitting. Also the rubber hose gets old. I replaced all my rubber hose 4 years ago and still have to tighten up the clamps every now and then. It may also be that your pan or case halves bolts have loosened up. I can buy lots of cases of oil before paying for an engine overhaul 1 Quote Link to comment Share on other sites More sharing options...

Once enough collected it would then show up as streaks on the NLG doors. 1 Quote Link to comment Share on other sites More sharing options...

Then get some of this https://smile.amazon.com/Aircraft-Tool-Supply-Magnaflux-Spotcheck/dp/B005VR2RDK/ref=sr_1_1?ie=UTF8&qid=1534178348&sr=8-1&keywords=magnaflux+developer&dpID=31xb0A1RlKL&preST=_QL70_&dpSrc=srch and spray it all over the area after the cleaned engine dries. Then fire it up, run it hard for a bit. Your source of the leak will be apparent. CB version is some spay foot powder, but not as good.
