No, apart from filler cap nothing off (in particular not the filter - you want oil in the engine not on the floor), nothing closed. After all the pressure needed/wanted is nothing more than you (or rather your kid) would need to blow bubbles up a glass of soft drink through a straw.
Learned it...
So you forgot the vaseline, or the engine was not started all winter, or you mistakenly simply changed both filter and oil at the same time? Anyway there is oil in the sump, but it does not get to the pump!
Here is the easy remedy, only needs a helping hand and an air compressor:
Filler cap...
Ordered two new cork ones simply because even if I try to flatten the pan (slightly deformed/uneven by all bolts - previously torqued?) I never think I can make it good enough. And hylomar or something similar of course. Only still I wonder who would ever use a composite gasket, unless with a...
My cure was this: Remove the kickdown cable. Get rid of the damaged plastic on the lower 5-6 cm. Cut the cable in the middle of the free section at the top. There was ca 1,5 cm between the end bracket and the pressed on stop. Get heat shrink tube (glue type) down at the exposed/leaking end plus...
As described in another thread I also had a BW35 mysterious leak problem. After fixing it, I closed the box with a new sump gasket as to workshop manual instructions (vaseline and torque): It was leaking - really pouring leaking. Tried some more torque, but no change. After draining and taking...
Yes, of course the rear pump is high pressure and the front one only to provide flow. And sure enough RTC0035 is not in the P6 Parts Catalogue.
Then bottom line: Mysterious slow spills - several litres - when the car has been standing for hours/days/weeks are typically due to air ingress in the...
Well, I only considered the front pump. I know there is a another rear one, and I can see the check valve for that in the parts book. But then my assumptions for the front circuit so far still seem to be correct and able to explain those leaks.
BW35 and mysterious leaks while parked - a possible explanation.....
----------------------
After forum reading, catalogue study, and thinking, I have come to this belief: Correct me if I am wrong or missing something.
We may consider the system as a box with a fluid pan and a pump that sends...
I found my leak: It comes dripping out from the sleeve around the bottom end of the kickdown cable. So nothing wrong with the breather. But if the breather tube (communicating vessels) should be of any benefit, the bottom end of the kickdown must be airtight. And is it really supposed to be...
Parts catalogue illustration: According to the engine number my car should have this version. Later ones are quite similar. As can be seen the engineers clearly thought about communicating vessels. Even if the check (non-return) valves are inoperative the 'up-and-down' breather will prevent...
There may be something there. I shall check when back at the garage. If the breather tube does NOT pass/end over the top level of the converter, spills may/will occur if air can anyhow slip into the converter when the car is left standing idle...
Good idea. Who might that be?
Besides I came to think: Where would the overflow typically come out. Is there a breather of some kind somewhere or is it by some some spindle - speedo drive - shift rod - anything?
An engineer (I) come to think "communicating vessels": If the (un)inteded...
