It seems this is a significant problem with the standard setup on Series Land Rover gearboxes and diffs`. Some owners have apparently overcome it by making up breathers similar to those on Defenders.

Sorry, the original post was about wading plugs on the County / Defender. I based my reply on the original question. I was unaware you were referring to Series in this post.

You are correct, there is a lot to be desired in the breathers of earlier Land Rovers, and tube breathers above to a high level on the Series would be a great improvement.

Same principle of hot air inside housing contracting when immersed in cold water applies for timing and clutch housings as well as gearboxes, etc. Appropriate breather tube setups ensure only air is sucked in, not water.

I left out a wading plug on my old 90 and this happened to the inside of the timing cover

And then nackered pretty much everything isdie the tiimming cover. Was full boar on the revs in a mud hole when the cambelt snapped. Since then i have left in the wading plug and fitted a breather to the top of the3 timing cover. Land rover do a plate that replace the plate on the front of the timing cover that comes with a breather pipe. . But you still have to check every now and again ( manly when during car servie) that there is no build up of oil in there


BTW on my winch challenge 90 i had breathers on the Timing cover , Bell housing , Power steering fluid res, and Injector pump, plus all the normal ones

That looks rather narsty Reads, i think i need to get some plugs or setup breathers on timing cover and bellhousing.

Mine never had plugs when I bought it :(

Also quick question what is the thread size of the wading plug please?Assuming both timing/bellhousing are the same size
