leak only happens when engine turned over.
Thought it was crank seal but no sign of it from there!
Oil pisses out from somewhere above the diff and comes down the engine side of the diff!
So have I missed a seal or a bolt on that end of the engine????
-
Len you sure its not gearbox oil? Have a sniff of it. When i had a leak it lead me to believe it was the sump after faffing about for days we took the gearbox off and what not and you could blatently see where it was comming from. The crank seal bent on itself.
-
definitely not mate! Dipstick dont lie!
-
Leak from that corner of the head gasket? How much oil you talking?
-
There is a core plug at on the side of the block at the end of the intermediate shaft its a oil core plug not a coolant plug.
Its covered by the metal plate between bell housing and block anything bellow this can only be sump gasket or crank seal or crank seal flange gasket or it has a m6 bolt missing.

Is yours an ABF?
I've got an oil leak too, seems fairly major as when I look down the back, the subframe had it pooling and it's wet under the dizzy and over the top of the gearbox..
Not sure what it is, I'm too new to the mk3 golf to know the usual places to check!!
Can you post photos of what you're seeing? I'll post some tomorrow and maybe we have the same issue lol.
Was gonna have a look under mine when I do the oil change next weekend..
But my leak is coming from under the dizzy near the 2 or 3 sensors plugged into the side of the engine and whatever it is is pissing oil out everywhere!
-
Well I have started stripping down the engine to take it out and have a good look!
Like Chris has said above it might be a missing bolt on the plate housing the end crank seal or a missing stud maybe!
But cant see that until I get the engine out and split away the gearbox.
have heard I could take the gearbox off only but now I know I have been turning it over with reduced oil in there I want to check the bores and all bearings for any damage.
Plus that allows me to swap to the correct crank sensor trigger wheel.
Will let ya know how I get on

Ever heard of Sisyphus, "The struggle itself is enough for a mans heart" :wink:
Keep at it Len I need to know why it does not work.

Awesome man. I wish i was better/more confident/more knowledgeable about stripping engines down.. would love to be able to just remove and reinsert engines as needed. I should've gone to mechanics college instead of uni :P
do let us know how you get on, and post as many photos as you can be arsed to take whilst you're elbow deep in engine bits! would be good to see what you see when you find the leak, might help me find mine.

I've just rebuilt my valver. Pretty simple & straight forward to do..
These middle of job pics might help you to pin point your oil leak?

Robracer nice and clean AGG 8V block.
xAntiVenxm your leak could be dripping down from the rubber rocker gasket, or dizzy o ring seal some times the only way on a engine that has been used for a while is to get some self dissolving engine or brake cleaner and clean the area where you think the leak is.
Only ever use a pressure washer if your confident the water wont affect the electrics and you have the time to dry everything off.
-
Robracer my oil leak is on the end where the engine stand is!
-
The only seals that can leak on the gearbox end of the block is the crankshaft oil seal, common leak area by the way. Or the that end of the oil sump? I found a threaded m6 thread on the bottom of the crankshaft oil plate, so I tapped that out to an M8 thread. It's,best to replace all seals if you can mate

Thanks man. Replacing rocker gasket (and therefore throttle and intlet manifold gasket too) is on my to-do list for next paycheck.
Got some engine degreaser spray coming my way this week as well :wink: so will clean the block down and see if it reveals anything! :laugh:
-
Missing or damaged oil gallery coreplug maybe
-
A coreplug could be at fault?
But I managed to go through 2.5 litres of de-greaser cleaning everything! But its worth it..
I've gone for the oem clean look. i work in the automotive carbon industry

This new engine of mine was assembled with a new crank seal.
It was taken apart again to sort the squirters but fitted back correctly?????????
That's the bit I'm not sure of and my thoughts are a missing bolt
-
Looks like you have a hidden leak? All you can do is take things apart till you see it. Not very helpful i know but you don't have many other options..
-
As i said at the start the seal could have bent back on itself. I had the same issue. When i put my new victor seal on i slapped on loads of oil and it slid on nicely and i double checked it to make sure it didnt do a repeat
-
Its very easy to damage a new seal on assembly.
Just because its new doesn't rule it out.
