This also doesn’t take into consideration the cost of the oil that is leaking. This is a 5SFE and A140E transmission. Why is this? Thanks. These gearboxes have internal plumbing with orifices to control pressure and nozzles to deliver cool, clean oil to bearings and gear meshes. Here are the most common oil leak symptoms: Oil Under the Car– The most obvious symptom of an oil leak is the little puddle of oil or the dots that you’ll find under your Ion. I've never heard that one before. No cracks, leaks from the transmission, mechanic said the oil is transmission oil and it came out from the breather, the car did drive at the mechanic's no issues, i got into the car, put it in reverse and the transmission slipped. Yes, you are right. Updated post 9 Just trying to figure out what is up with my 2007 WK. Clicking this will make more experts see the question and we will remind you when it gets answered. I've come here as I've seen a lot of members know their stuff with the Zetec engine. Generally, no oil can be viewed in a sight glass during operation, even though this might be several inches below the minimum line. It will just intermittently start spurting out fluid. An integrated oil pump moves oil from the sump on the high-speed side, through a filter and a cooler as directed by the manifold block. It was about 3-4 inches across. But relatively small housings alone lack the capacity to reject the heat generated in the process of converting low speed high-torque rotational energy from the rotor into energy for the generator. Opening a few of the ventilation holes (letting air flow through the filter) activates these filters. Thus the appearance of a leak. A gearbox’s internal plumbing delivers cool, clean oil to where needed. If the oil you have put is of lesser viscosity than the specified oil, replace it immediately. No engine code comes up when I run the obd 2 on it. That's interesting and helpful. I would top it off n level it n ride it again and it would do it again. In practice, breathers must be timely dismantled and cleaned of dirt and remaining oil. Not unusual. Gearbox oil leaks present a special challenge in an outdoor green-power application. Can the transmission cooler in the new radiator be bad? It only has 90k and shifts fine, there's just a pretty bad leak. So when it would purge that little pocket area would be full. I don't know your transmission but most domestics have a vent tube/hose. Last edited by a moderator: Jun 7, 2009. I just replaced the solenoid pack in the transmission valve body today cuz I had that code. Modern wind-turbine gear designs provide a necessary power-to-weight ratio. Jammr, Sep 2, 2008 #6. My friend goes to school and is learning to be a mechanic and his teacher said he recommends switching out the transmission! It went to a Transmission shop. When it gets up to the breather there is some "pushing out" of the oil there as the temp in the case warms and the air in there expands. It is definatly coming from breather hose. If the oil has exceeded the Max limit, the oil will spill out of the breather due to the centrifugal forces of gears rotating at high speeds. Critical measurements are oil temperatures at various sensors, and oil pressure before and after the filters. I have a 99 sporty 1200, all of a sudden I have this oil leak out the breather hose. Unfortunately, they have been so prevalent, leaks are defined by their degree. Hmmm. Can the transmission cooler in the new radiator be bad? The thing is that oil particles can be squeezed out through breathers, and it may lead to severe contamination. And then there is potential for a high water content in the oil from humidity and condensation. All rights reserved. Stevie, nothing will stop me from getting to the HU meeting, like you, i would like to put faces to names, and share a couple of drinks. That code is now gone but the fluid is still leaking out of the vent tube. Also check for any drain hole on the bell housing - Landrovers had a bracket with a special plug which was to be fitted … If the filter becomes clogged and loses the ability to pass air, the gearbox will breathe through the labyrinth seals and expel oil along the way. One other leak that’s also common on most Harleys is the dreaded wet-sump, when oil collects in the crankcase. A benefit of a low sump oil level system is the choice to use labyrinth seals. Browse the most current issue of Windpower Engineering & Development and back issues in an easy to use high quality format. WPE, Story By: Paul Baker, director of business development, Frontier Pro Services, www.frontierpro.com, The problem with my 2000 estima 3.0 araes bought from Japan is, it heavily oil leaks. 23oz was in there and it calls for 24oz. This really kinda stinks. A loose dipstick, clogged breather, improper dipstick marking and water in the transmission are also probable causes of the problem. When it comes to leakage, the only real solution is to take down the machine and repair it in order to stop the leak. My car has 116000 miles. The leaking oil gets on the frame, gearbox and fan blades, than gathers dirt. 1) Engine oil from the crankshaft oil seal 2) Geabox oil from a failed gearbox input seal 3) Clutch fluid from a failing clutch slave cylinder seal. The breather is a small valve, with a spring loaded ball bearing that pushes open and let's pressure exit the valve. Really? Somebody has to know something. Still both are leaking but my main concern is the gearbox , diff is getting less amount on the ground now. Good luck. went for a 5 min. I don't know about the newer coaches, but my 2014 and many others have had an issue with the engine fan drive gearbox breather leaking oil. I also checked the oil cooler area which is fine. correct? Zetec 2.0 oil breather spitting oil I've finally finished the build on my Si. It's more than a slow drip. It has been my experience that the OEM recommended oil level is exactly halfway between the minimum and maximum (usually not more than two inches between), and should be viewed on the manual sight glass after 30 minutes at rest. ride and it was leaking pretty good. Oil has started leaking thru the breather vent. Discussion in 'Oil' started by dontask, Aug 16, 2008. My system is to go in there and use a very tacky gasket sealant of some kind to basically glue the gasket to the block and the breather itself. Copyright © 2015 Shogun Interactive Development. Then it seeps out and down the gear case body. Breathers face their own problems such as splash back of oil, outside air moisture and dirt ingress that can all lead to clogging of the filter.
