What is it and why is it leaking ?

neilcmusic · Apr 23, 2016

Morning , weathers improving so I'm trying to enjoy Landy , I have found an oil drip "can someone please identify the part and tell me if its easy to replace , thanks for your continued support

Oilis leaking from circular plastic piece which has spade connector on it so I'm assuming it's some sort of sensor

oil pressure switch. Think it just unscrews - can't be more that a fiver to replace I would imagine.
Check it's tight first.

Land Raver · Apr 23, 2016

Just a thought, if it's dripping a bit at standstill be careful it's not leaking loads of oil out when engine running as it will be under more pressure. You don't want a spectacular oil loss after all you've spent on the engine.

Sometimes they have a copper washer, may have been left off - try tightening it [don't over do it!] a VERY light smear of instant gasket can help. As long as it's not pumping out when engine running nothing to much to worry about - far worse oil leaks are common...........................
When your bank account has recovered replace with a proper, mechanical oil pressure gauge - good luck

neilcmusic · Apr 23, 2016

Its really tight as it is! , yeah its strange , if you look at the picture (ive cleaned it up) its leaking from the end nearer to where the spade connector is , so its not even a joint its sort of coming from out of the plastic , ill replace it if its only cheap , why not ive nearly replaced the rest of the Landy. Thanks

Oh re this , when I take it off will Oil start shooting out under pressure or wont there be an issue if Landy is stationary with engine off.

You will find the photo is common tarmac. It doesnt leak oil until you buy a Land Rover and then gallons of the stuff leak up through to the surface. Land Rovers are actually 'oil magnetic negative' so the oil seeping up out of the ground is the positively charged oil remaining from the heating process on natural tar before it is mixed with stone chippings.
Unfortunately you cant stop this and it will continue for the life of your vehicle. In fact the older the Land Rover the higher the negative charge so the pools of surface oil only increase.

Then it's knackered.............................. but no - there is no pressure unless engine is running, good like

Thats great , Thanks Bobsticle

Yes, Manchester Univarsingty have been studying the lay lines through the Middlands and have deduced most vehicles manufactured in central England are indeed 'Negative oil magnetic'.
Land Rovers suffer more than most as ferrous metals seem to amplify the effect. Series Land Rovers have been known to pull up pools of oil right through concrete and steel spill trays.

Ah this explains why my mums drive now has oil stains under my Landy, I knew it wasn't leaking coz that's just crazy talk.

Bloody Hell , I Live in Solihull so im getting it from both ends here, Landy owner in West mids!!, ive got no chance
also Ive owned a few Rovers that ended up with more Oil on the drive than in the engine so again point proven ,
they dont teach you this stuff as school ,at least not in West Mids.

neilcmusic · Apr 28, 2016

OK new one has arrived , I'm unsure how the old one unscrews , if you look at the picture the existing one is round like a coin so how am I going to grip it ? Does anyone have any experience re this? I'm sure the bolt above the disc is part of the thing it screws into rather than the switch itself

waldamar · Apr 28, 2016

BEHIND the plastic dome is a hex bit that you can get a little open end spanner on [or at least should be] isn't your new one like that?

neilcmusic · Apr 28, 2016

I'll have another look , new one looks like this so it easy to get a spanner around it
Thanks

waldamar · Apr 29, 2016

They do vary - as long as it's the same thread all should be good - looks like your old one has the small hex bit behind the plastic "dome" - look out for little copper washer, some had them, some didn't. A very light smear of instant gasket on the thread ONLY can help - but nowhere near the little hole at the end................... good luck,
ps. having spent that much on your rebuild I'd still suggest you get a mechanical oil pressure gauge.......................

neilcmusic · May 1, 2016

Thanks all , so when you say behind the dome do I actually need to remove the plastic dome to get to hex or is it very thin on other side of metal disc?

samc88 · May 1, 2016

No, the hex is on the engine side of the dome, you'll get it with an open ended spanner. You will get some oil coming out when you take it out. I wrapped my new one with PTFE tape before fitting and no leaks since

If they did teach us this at school we will be all driving Japanese cars can you imagine such a place we will have no car factories and every one would be a taxi driver

neilcmusic · May 1, 2016

Another "five minute job" if you look at the picture there is a hex part which a spanner could go around just above the disk , its about 1/2 inch long however this looks like an extension from what I've seen on internet , this is stuck solid , disk somehow has been screwed in flush up to this but I'm not sure how as there no way to actually turn disk , we all know what will happen if I put too much force on it , it will snap off !!

samc88 · May 1, 2016

Turn that hex bit, it should come out then. Get a spanner and put a length of tube over it to get better leverage

What is it and why is it leaking ?
