I had my CH601HDS, Taildragger, inspected on Nov. 11, 2004. I did not have my medical back yet, so decided to short hop a couple of more times that afternoon. At 60 MPH, just at lift off, the engine (912 UL) seized. The airplane made an automatic wheel landing and I coasted off the runway. 27 hours total on the Hobbs meter. The seizure was due to oil starvation. Destroyed the crank, cam and two cylinders to the tune of $6,886.91 (US). Why oil starvation? I had installed the oil tank according to the oil system installation instructions on page 35 of the 912 Installation Manual. The illustration of the oil tank is incorrect. The oil tank is plumbed internally the reverse of the illustration. Follow the illustration and you will connect the line to the oil cooler/oil pump to the return side of the oil tank and the return line from the engine to the supply side of the oil tank - I did. How do you get 2.7 hours run time? I changed oil three time during that period. The procedure I used resulted in excess oil in the engine case which was pumped back into the oil tank, over filling it so that the oil level raised to the point that oil was transferred back to the engine through the top of the tank. At lower RPMs this seems to have lubricated the engine fine, and yes I had normal oil pressure indication. On the last, disastrous run, I had done a full power check on the runup pad prior to taxing to the runway. I appears that at full power, the tank was filled to the point that oil blew out the overflow. When starting this short hop run I do not recall rechecking the oil pressure prior to advancing to full power - I was concentrating on oil/coolant temps. and RPM. Rotax has agreed to pay 1/2 the repair bill and is busy correcting the Installation Manuals, Service Bulletins and Service Instructions on the Rotax Owners web site. The 912 & 914 engines use the same oil tank and illustrations for both engines show the reversed drawing.

And hopefully you are helping some others to catch this error. I am using an older edition of the installation guide and I just double checked their plumbing diagram. It is correct (1998) so they must have changed it since then. It makes sense that if this tank is hooked up backwards, the suction on the tank is no longer performed thru the tube that goes to the bottom of the tank, so there would be oil starvation in short order. Fantastic that you got them to pay for half of the repair... still your half is a lot of money! You should ultimately have a service bulletin issued in your honor! Will be watching!

It shows the oil line to the oil cooler and oil pump connected to the fitting on the left side of the oil tank (vent fitting facing left). The fitting on the left side, in fact, ends on the top of the oil can and does not continue via a tube to the bottom of the tank - that is on the other side.

Our mechanic was sent to Kodiak (some years ago) for especial 912 training. The most important thing is to bleed the air from the oil system the first time, before the engine is started. Another inportant thing is the oil level check procedure. with the tank cap opened, IGNITION KEY "OFF", turn the prop forward until the tank makes a "fast drinking coke" :-) sound. This means that all the oil from the crankcase is in the oil tank. Saludos Gary Gower Do not archive. Jon Croke wrote: --> Zenith-List message posted by: "Jon Croke" Leo, That is quite a story.

Sorry to hear about your misfortune on the Rotax engine. If you read this installation instructions from their manual, and it does not work that way, it looks like they should be responsible for the fault. Just my opinion. They charge you enough already for parts to cover minor repair like this. Just glad no one got hurt. I would like to know if the Zenith instructions are correct. The outlet from the oil reservoir tank is on the left side and connects to the left of the oil cooler. Then it is connected to the engine on the right lower side beneath the oil pressure sender. Then it exits from the bottom of the engine back into the oil reservoir. Is this the correct understanding of the oil flow? I just bought the engine oil today, and am about to go through this same ordeal. Good luck with your new engine and getting Rotax to pay for it. Best wishes, Johann G.

I concur that this drawing depiction is at best, confusing. There are other ways to confirm proper hookup, but I agree that if you used this diagram alone, you would hook it up wrong! (to our many 912 owners: take a look at YOUR installation manual.... the tank picture is drawn a bit incorrectly... if you were a print draftsman, you would have to agree that there are some mistakes here!)

(Kinda like what is life?) It depends how you view the tank: from the front or the back? What is the front of the tank? It is ROUND!! So... the port on the top of the tank labeled "OUT" goes to your oil cooler... and then into the engine (the oil leaves this "OUT" port and goes into the cooler and then into the engine). The BOTTOM of the engine (the output) routes to the remaining port on the tank.

I added the paper filter when "swarf" from my fuel tanks was seen in the sample drained before I'd go flying. In the sun it looked like a miniature tornado of microscopic glitter. After a seeping shutoff valve was replaced, the tanks were drained, the finger strainers were unclogged, the tank was brushed and wiped clean. The glitter was gone for good. I like the assurance that the in-line filters offer as an additional hedge keeping the carbs from catching the small stuff. Before the paper filter, I was finding the same stuff in the Bing bowls and in the gascolator bucket. I'd keep an inline filter in the inventory and reconsider a standard gascolator over the unscreened ZAC model.
