just don't get it on your paintwork in case it is brake fluid
You'll find out in a short time
I am fairly relaxed about getting grease and oil on my hands when working on my cars and I have had a faceful of coolant but I would never deliberately taste any fluid from a car because they are all toxic.
Like wine tasting...please use the spittoon after. Or as Fred Flinstone would say "yabba dabba do" or a little dab will do. Pretty sure once that bitter taste hits your tongue you won't want to ingest it.
How's the wife Dom?

I can categorically say brake fluid has a bitter taste, sort of like an olive straight from the branch. Engine oil is sweet in comparison.
So had a good look at the brake booster and master cylinder both look good. Tested the booster seems to work well with engine running.
In all I drained about 100ml of some kind of oil fluid from the exhaust, I didn't taste this for obvious reasons but now starting to feel convinced its come from the engine somewhere.
Its not smoking with the exhaust off so difficult to narrow down.
Plan to fit carbi kits next week and refit the exhaust and see what happens I guess!!
Will let you all know how it goes
Something in the back of the scull says transmission fluid can be sucked in .
Probably vac driven modulator?
Can't recall mechanism but does the oil you drained give any indications between transmission fluid or engine oil.
Tounge test or gargle n spit optional
The early auto had a vacuum kick down. The later 010 had a mechanical throttle position kick down.
There were some issues changing into 3 rd gear after we noticed the smoke.
The oil does seem a bit like tranny oil??
Check fluid level first.
Think it's when warm( doesn't make much difference) and in park or neutral?
That may account for poor change.
Otherwise a non functioning modulator? May be the issue ?
Been a while so can't recall details except that you can loose fluid via engine operation.
Might be some helpful links.
Any idea how I would check/challenge the modulat
Any idea how I would check the modulator? cbus
Do you have a 003 or an 010 transmission? If it’s an 010 there’s no chance of burning auto transmission fluid through the exhaust because it doesn’t have a vacuum modulator.
Here’s a pic of an 010 (towards the left of the photo is the rear of the bus, therefore, you’re looking at the right side of the transmission in this pick). The shifter cable can be seen coming into the box from the lower right of the picture and connecting to the shifter arm which hangs down. From the same spindle, there’s another arm rising upwards; that’s the mechanical kick down mechanism and is connected to your accelerator linkage.
And here’s a pic of a 003. Note that there’s a hose in the foreground (that end of the gearbox faces the rear of the bus) which is the vacuum kick down; it’s not on the 010. Also, the shifter arm is on the left side of the bus (as looking from rear to front) on the 003 whilst it’s on the right of the bus along with the kick down mechanism on an 010.
So it looks like I have the 003.
I removed this hose that runs to that exhaust manifold and it’s full of tranny fluid..
Yes, tranny fluid in that vacuum hose would feed fluid into your engine and cause white smoke. You’d also be getting a dropping tranny fluid level and that could cause problems with gear changes.
I expect there’s a diaphragm broken in your vacuum modulator.
Are these modulators repairable or do you know where I can buy one?
I guess they would be repairable but I don’t know details. I took my whole 010 gearbox to Auto Medic at West Gosford and got a complete overhaul. Now I know it’ll be all good for a long time to come.
Worth trying a few auto outlets.
Seems varying prices.
Also a few variants on the box between applications which may or may not be critical so check your part number and do search.
May also need adjustment after installation ?
Run new lines as well.
Here is one in stock
