Hi there all,
Before I layed my car up for some work to be done on it, Debbie my partner and I went for a ten minute drive up the road to our local 4 Square (grocery store) for supplies and left, reversing out we left a significant amount of red oil on the car park.
Oops a bit embarrassing.
Got back home and checked the fluid level, not registering any oil.
I search for a leak, to no avail.
A month or two later i have just removed the trans sump, cleaned and replaced gasket.
Filled up with fluid tonight and got about six litres in and heard dripping, upon checking it is pouring out the breather hose!
This leads me to believe this is where my car park leak came from after a run????!!!!!
The Transmission has been replaced by a Transmission company a few years ago before i got it and the breather hose which is joined to the filler Hose, (approx. 2 inches up from where it enters the trans) comes up and lays across the bell housing and feeds down again to beneath the engine.
I see this should have a bracket to mount it to something (in an exploded view diag,) maybe higher than the filler tube?
Can anybody help with why it should empty through this breather pipe,should it lay where it is?
I have used the car before regularly and have had no leak.
Appreciate you help
Thanks Karl
 
Sounds like it's been overfilled by a huge amount.
Normal drain/ sump removal only takes approx 3 to 3.5 litres if I remember rightly.
Check out Harvey's section on here about correct oil level checking and if it's a type 35 these do leak if layed up for some time.

yes that i may have done lol,
I have added an external cooler and bypassed the radiator one, so will fill these lines up when i get to start it i guess.
i also wonder if the breather pipe should be higher up or vertical as it leaked through this pipe on a drive
before
can someone tell me if it should be mounted and where with a bracket ?
Thanks again
 
Not sure of the internal layout but could the breather actually be syphoning the oil out under certain circumstances especially if its outlet is below the oil level Raising the end could well be beneficial

The cooler and pipes will fill as soon as the engine runs. If filling from totally empty, (not draining and refilling) then you won't be able to get enough fluid in without running the engine first.

It should run up to roughly the top of the dipstick tube, (where there should be two clips, one on the way up, one on the way down) then loop back down and run through another clip on the O/S upper tailshaft bolt.

The fluid level in use should be just below sump gasket level, and the breathers vent out up on the dipstick tube, or out of the top of the casing on the 2000/2200, so it shouldn't be able to syphon out.
 
Thanks Harvey, i have a feeling when the box was replaced the breather pipe was dumped across the top of the bell housing as it is not clipped anywhere.
I shall investigate and clip it up.
I will put my dash back together and the alternator in and start it up to fill the lines up.

Thanks Rover p480, seems it had siphoned out on our trip up the road, strange it hadnt done it on many previous drives though?
