I keep developing new oil leaks
The order of events was as follows:
1. Had no oil leaks at all
2. Extended diff and gearbox breathers and plumbed into the airbox
3. Noticed oil in the airbox - tried to narrow down where it was coming from but when I disconnected each breather in turn no oil was found to leak from them. However there was oil throughout the whole extended breather.
4. Noticed new oil leaks from where the rear propshaft attaches both to the rear diff and the transfer box - Ian suggested there may be a link between the extended breathers and the new oil leaks.
5. After a six hour motorway drive, I've developed a quite significant oil leak from where the front propshaft connects to the diff and there was more oil in the airbox.
How much suction is there in the airbox? Could it be that where I've plumbed the breathers into the airbox it is creating a vacuum in the diffs (and the gearbox) and has blown the seals by pulling air through - hence the oil also being pulled up into the airbox?
I'm going to extend the breather further - to the top of the snorkel to remove any vaccum effect as a possibility.
Also, I've noticed that despite putting new oil in the diffs less than 800 miles ago it looks like s**t. I even drained a bit out the rear and it was shocking. How many times should I put new new oil in and drain it off to remove the crap in there?
