The convertor drains back, overfills the trans, and the selector shaft seal allows fluid to escape. Mongrel seal to replace, but if the car is used once a week, no issues.
That drain back ALSO takes the pan level ABOVE the gasket line, and they leak badly, hence why I use NO gasket, and NO leaks.
Probably only a SMALL amount of fluid in real terms, as that stuff spreads and looks more than it actually is.
Jacked the car up today and had a look.
The auto fluid is leaking from the Vacuum modulator
The pipe is not connected and I cant see it anywhere so I suppose its missing.
Weather the manifold end is blocked off I don’t know as I don’t know where it connects.
There is also a leak from the back of the engine, I tried to tighten the sump bolts but they were already tight
Leak at the back of the engine could be the half-moon seals. Mine did the same thing until I replaced them. Not the most fun of projects, but I'm leak-free two years on.
Back of the engine leaks, as someone mentioned, can trickle from the top. The half moon seals as well as the banjo fittings, and oil sending unit are usual suspects.
The engine oil leak seems to be above the starter somewhere, where the starter bolts on, there is engine oil and below it.
i have checked the banjo fittings and around that area, cant see anything.
Fitted a new vacuum modulator but I cant find the hose anywhere.
I found the manifold end, as Grant told me where to look but the other end, I cant find.
I am thinking its been burnt off, as its so close to the exhaust.
I was surprised how cheap the modulator was and made in the US of A
Hose runs BEHIND that insulation panel. Fun to thread thru, NOT.
I used a cut scrap of Header Wrap (speed shop stuff used on Hotrods) to wrap around the exhaust pipe at the modulator, thus protecting the modulator AND the vac elbow/hose. Held in place with a coupla hose clamps.
Most common oil leak source where you are searching is the idiot light oil switch, the SMALL one. Followed closely by the Idiot gauge switch (the BIG one), and then the "D" seals at the back of the head.
You wont SEE anything, trust us all on that. Wipe your hand around the rear of the RH camcover and head, and when it comes out oily, you found the leak. If the hand is clean at the "D" seals, and the banjo bolts, the oil switches are the culprit.
well,
I couldn’t find the hose underneath the car, but I could see something like, what I thought was insulation.
I tried to follow the pipe from the top with an end scope and found it was heading in the direction of the, what I thought might be insulation
So I decided to pull it out
It was quite difficult to pull out as it was jammed between the engine and the body.
It looks like about eight inches of it has been burnt away, so obviously there was a fire there
It was what I thought was insulation
So that two fires this car has had.
Looked everywhere for the oil leak, no luck
I have already fitted a new idiot light switch as this was damaged by the other fire
thanks Grant
Perhaps I will find the vacuum hose there and trace it back to where ever it is hiding.
Its awful close to the exhaust
my vac hose took the same route and was very very close to the exhaust. Took grants advice and re routed it behind the insulation , not that bad a job but worth doing.
I did mine while the engine was out, there's an option?????
Another leaker is the o/ring of the distributor base. Oil dribdles down the "V" and out the back, and for some strange Aussie reason, the A bank side seems to be the favoured.
