Cornish Rattler Posted May 30, 2016 Share Posted May 30, 2016 Hi guys When not off roading do you normally take them out or leave them in, i have been running with them in for months then read somewhere you should always take them out but son did Silverdale last week and Kirton yesterday and on both occations forgot to fit them so i am thinking of fitting them in and leaving them in, what do you guys do.

Jocklandjohn Posted May 30, 2016 Share Posted May 30, 2016 I leave mine out so I know if I DO have a leak! (see above from Red90) and fit if needed. Quote Link to comment Share on other sites More sharing options...
Cornish Rattler Posted May 30, 2016 Author Share Posted May 30, 2016 Ok nice one I will leave them in Quote Link to comment Share on other sites More sharing options...
Paddy Posted May 30, 2016 Share Posted May 30, 2016 I leave mine out, for the 2 minutes it takes to fit I’ll fit before wading etc. Without plugs in you’ll see if your clutch slave leaks and oil in/on the timing belt. As I found out after prolonged wading (weeks), water ingress through crank dust seal behind the front pulley which amounted to a cup full on removing timing chest plug!

western Posted May 30, 2016 Share Posted May 30, 2016 Mine are out too, haven't needed to fit them for years. Quote Link to comment Share on other sites More sharing options...
Cornish Rattler Posted May 30, 2016 Author Share Posted May 30, 2016 Cheer's it's just that we get the Landy ready for off roading and forget to fit the plugs in so with the new engine going in with new gaskets and seals fitted I will fit the plugs but keep an eye on them Quote Link to comment Share on other sites More sharing options...
Boydie Posted May 30, 2016 Share Posted May 30, 2016 Just a tip here, and this is gained from bitter experience. If the wading plug is fitted and the engine is hot and you go into deepish water, that is above the engine crank depth ( about 600mm deep) the timing cover and bell housings are going to rapidly cool down, the air inside will contract and water WILL be sucked into the timing cover through the front dust seal and into the bellhousing through the bellhousing face joint. If you're going to be doing a lot of wading drill the top of the timing cover and bell housing and run 1/4" breather hoses to a high position. If you go to my photos you can see how I did my front cover. On the bellhousing I rescued an axle banjo fitting from my local wreckers and tapped the top of the bell housing at about 2 o'clock to suit the banjo. I've never had any water egress problems since. 1 Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 31, 2016 Share Posted May 31, 2016 I run with my plugs in and grease/check them from time to time, I have a breather on my timing chest and boost diaphragm too. If you've got an oil leak either clutch or engine oil, having the wading plug in wont stop it from seeping through the bell-housing joint (unless you put sealant on the joint then yes it might keep it captured).

muddy Posted May 31, 2016 Share Posted May 31, 2016 I put swivel push fit connectors in the wading plug holes and run my breathers to them, you can just uncllip the pipe to check for any water/oil ingress every time you grease the props wich is of course every time you've been off road. Will. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted May 31, 2016 Share Posted May 31, 2016 I always used to run with mine in and pop them out every now and then. Quote Link to comment Share on other sites More sharing options...

Hi Maverik, how did you attach one to the boost diaphragm? Harry Quote Link to comment Share on other sites More sharing options...

Thanks for that, this could be my problem. This last winter floods saw me daily driving through 24-30” of floods for a few weeks, outgoing cold engine and return would be hot Never thought about it pulling a bit of a vacuum. A job to coincide with new timing belt and renewing the dust seal Quote Link to comment Share on other sites More sharing options...
SPendrey Posted October 10, 2016 Share Posted October 10, 2016 Was thinking about this recently... if wading plugs are not fitted AND you have a breather, then at any time you are stationary in deep water then the water will surely find its level and fill the timing case. However, if you didn't have a breather, then some amount of water may be sucked in, but would soon run out again once on dry land, and it would only come in to the extent that the reduction in air volume allows. Beyond that, the air in the timing case would prevent water ingress. So, is the best option to fit the plugs, or to not have a breather?

Snagger Posted October 10, 2016 Share Posted October 10, 2016 The best option is to have the raised breather and fit the plugs for wading and remove them afterwards. But I think the risk of running with wading plugs permanently installed is higher than wading without them (no breather). If you can't remember to fit the plugs before wading, then put a storage bracket on the dash or next to the transfer box lever. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted October 10, 2016 Share Posted October 10, 2016 I had absolutely no issues running with the wading plugs installed all the time and just removing them every now and then? Quote Link to comment Share on other sites More sharing options...
Snagger Posted October 10, 2016 Share Posted October 10, 2016 ... Because you didn't have an oil seal fail. If you keep the plugs in and have the crank front seal fail, the timing case will get a hell of a lot of oil in it, almost guaranteeing the timing belt will slip and jump a tooth or more and causing subsequent damage to the valves, pitons and rocker gear. If you leave the plug out and have such a seal failure, then the oil will run out the bottom and give you good warning with no further harm.
