oil in air filter

Hello all being new to landys could you help?

i ahve just serviced my 90 county and found exsesive oil in the air filter i assume this is not normall can you help?

tim

Just a daft suggestion but did you over fill the oil by any chance?

I dont know i have just bought it i dint i am very methodical when i change oil this was before i had changed the oil and filters i noticed it was soiled so i cahnged it i have not checked the air filter since?


it had a grommit in the bottom of the air filter base which i removed to get rid of any further oil and dried air filter canister with a rag.

it seems to be now dripping when landy is stationary from the base of the canister???

Hi,

You did not say what type of engine your 90 has. I suspect it is a 19j 2.5 Turbo Diesel. If it is this seems to be a common problem with these engines. The problem is caused by high pressure in the crank case. The crank case is vented into the rocker cover near the back of the engine. In turn the pressure from the rocker cover gets vented to the air intake pipe just before the air filter. The rocker cover vent is only supposed to remove any oil vapour that is present but, as oil is being forced up from the crank case this is removed in the same way.

You really have three options,
1) Rebuild the engine with new piston rings and hope this stops the problem. it seems that this does not always stop the problem.
2) If in all other ways the engine works fine, leave it and buy a washable K&N air filter.
3) If in all other ways the engine works fine, leave it and buy a new standard air filter before you take it for M.O.T.

I have had a 1998 110" with the 19j Turbo Diesel fitted it has the same problem, keeps blowing oil into the air filter. The engine runs fine, has had no work done on it other than routine maintanence ( oil, water, filters changed etc). I have had the vehicle for 10 1/2 years now and it still does it.
The only thing I can say that may help, is do not push the engine to hard. The 19j engines can be a bit fragile, try not to run it at maximum load for any period of time, i.e drive at 60 mph on the motorway not 70. This has worked for my engine so far. It is now on 173000 miles.
Sorry not to be more help, best of luck with your vehicle.

Hi, again. Missed your last post.

The grommit you have removed is a drain hole for excess oil. Any oil that gets into the air filter canister is meant to drain out of the hole. The grommit should have looked like a ducks beak, sorry best discription I could think of, it is meant to close if any water presses on the bottom of the grommit. My 110 drips oil on to the drive, stops the near side chassis from rusting!

right if i was to replace this engine with a new one or exchange one would i be best to stick with same make and model engine or go for another which will adopt the same running gear?
Again looking for advice on above

If so were is the best place to get this done i live in Nuneaton area?


or do i sell and upgrade as i have seen some prices and it starts from £1750 for engine?

Or should i just leave it ???and put on KN air filter????

HELP!!

I presume you have got the 19j engine, ie non intercooled. Changing the engine for a re-conditioned unit may not solve the problem. Replacement of the engine for another type would be an option, but it depends on how much you are willing to spend? As finding a decent garage to do the job is another matter, can any one you know locally recommend anybody. I don't know of anybody in your area.
If you did change the engine a 200Tdi would probably be your best bet. However these are getting rare, there where a couple on Ebay the bids had reached the £800 - £900 mark with time left to run. Also aswell as the engine you will need all the intercooler parts as well. If you do look round for an engine remember that a Discovery 200Tdi will not fit straight into a 90, the turbo charger and manifolds are different.
The same thoughts went throught my mind when I dicovered my 19j engine did the same thing. I decided to wait to see if it got any worse before spending out on a new engine. As the engine on my vehicle works alright it was cheaper to change the air filter each year.
Talk to other people and a couple of independant Landrover specialists before you decide to spend lots of money.

will this engine go in the end thats whats bugging me or will it go along with this problem??


its just that me being me it anoys the hell out of me knowing thier is a fault just cause thier is a fault if you know what i mean?!!

I like to look after my kit and most of my cars are treated better than the misses..lol..
its a shame really as i have always had 4x4 all be it not landys..what an experieance for a first time landy eh.., but you dont think of removing the air filter when viewing ,,

would a 300 TDI engine fit??, i found this link for engines : http://www.turner-engineering.co.uk/html/strippedengines.html

I have thought of getting back to the guy who sold it to me but you know the score i would get little joy no doubt!! sold as seen ,,

I don't think a 300 Tdi engine will fit straight in, also i don't belive the LT77 gearbox will fit to a 300 Tdi without an adaptor kit. I have heard of Turner Engineering, one of the Landy mags uses them. The price for the 300 Tdi is for a stripped engine, you would need manifolds, turbo and all the other bits that bolt onto the engine. The 200 Tdi would be a better bet. As the price for this is for an exchange unit you would need to buy an engine to give them, but it should have all the bits on it that you need. Either way it would cost. If you definatly want to change the engine a re-manufactured one would be the best choice,if you just buy an engine from someone you might just inherit different problems. All this is cost permiting.
As for you current engine going, really there is no way to tell. Mine is on 173000 miles and working fine, others go at 100k miles. I have not heard of any of these engines giving out because of the oil/air filter issue.

thanks mate i appreceate your time an stuff for a green person to landys..anyway i still luv me 90 to bits ... a real 4x4 at last.

i use one alot i fly birds of prey and shoot alot and carnt wait to take i @ weekend:

this is my white Gyr male good rook bird!!! anything black that moves is dead meat!!

I have not heard of any of these engines giving out because of the oil/air filter issue. The main issue is that the engine is quite highly thermally stressed. Land Rover did not at the time have a powerfull diesel engine to compete with the Japanese 4x4's. They did do some work to improve the engine, but it is basicly the old 2.5 diesel with a turbo bolted on. No intercooler was ever fitted.
If you look after the engine and don't give it a hard time it should not fail. Make sure the cambelt is changed at regular intervals, book say's 6 years or 60k whick every is sooner, I change mine at 50k. Change the oil at the right times, keep an eye on the cooling system. All routine stuff.
I don't drive mine at full throttle on the motorways, it is happy cruising at 60 - 65 mph. It will go faster but it heats the engine up quickly. I do use full revs, but do not hold it there, just for accelerating throught the gears.
The best idea really is think long and hard before spending out.

Thanks mate!!


i am now wiser as i gomust say you are very informed!!

i think i will go with your option of TLC but as i said it anoys me as i tend to be a perfectionist if at all possble!

Your right it is an annoying fault.
I have at the moment put some wire wool inside the breather pipe from the rocker cover to the air filter. The idea is that this will filter out more oil than just the small filter that is in the oil filler cap. I will let you know how it goes.
As you obviously want to look after your vehicle and are relativly new to Land Rovers, you will near a lot of comments like 'it's a Land Rover they do that/make that noise'. Yes they do, but like all vehicles only when something is starting to go wrong or is loose. We all have to make the decision on whether to repair every small fault based on, severity of fault, cost, inconveniance or if waiting will allow you to rectifiy any other faults at the same time (tends to be cheaper).
land Rovers will give you hours of fun if looked after. If you have not done so already join a local club, you will find other people who have wealth of experince to help, advise and inform.
But above all have FUN!

got engine offer defender on a 92 62000 miles done with hoses intercooler and rad
with 3 mths warrenty trouble is £2000 ,,
but stil worth it so anyone in nuneaton who will fit??

Hi, Ive just bought a 1987 90 2.5TD (19J) and have got the same issue of oile in air filter. Also have oil vapour venting from the dipstick, which is same issue of crankcase pressure it would appear. I found some really good threads on the pressure issue on LandRover Enthusiast Forum, having searched for 'dipstick'.

I came up with a little mod tonight though to stop wasting the oil, and stop dropping it all under the car (on chassis, bulkhead, etc). It involved some rubber hose and a 500ml plastic bottle and cap. Bottle wedged between wing and air filter housing, rubber hose between dipstick and into bottle. Hey presto, caught myself a little puddle of oil in the bottle!

If anyone wants any pics if they want to do same, just email me [email protected]

Great idea but my old girls engine has now died a death!!


Finally started to knock in engine dont know what sounds like piston slap or sim?

So she sit on the drive till my Defender engine arrives and my mate fits

Missing driving the 90 already i have had to borrow a 309 GTI to get to work and i dont care what they say i hate all the comforts of a comfortable chair no engine noise / and fast speeds it aint a LANDROVER!!!!

LOOK AT THIS ONE !


Not knowing would this fit into my 90??? and if so whats involved??


1997 landrover 90/110 defender 300 tdi engine + box

ok stop do not re-place your engine the problem is the emmisons pipe that runs from the engine crankcase filter this is at the top of engine bolted onto rocker cover is a black looking set up follow to where it goes into the air box housing pull off blank of with grommit run that pipe now to your front chassis some where as this is what is blowing dirty oil into filter box this pipe is only the breather from the oil sump and is unburnt and is re routed to be burnt of as you can see not all burns off and comes through as oily breath from the engine i have done same on wifes 90 defender 200tdi and on my disco200tdi it is only dripping a little so why not treat your chassis to a bit rustproofing failing that make a catch tank hope this helps but dont replace your engine replace with new filter much cheaper regards colin

sorry mate can you explain again in laymans terms??

ok basicaly if you were to disconect the pipe running from the emmisons breather located on the top left hand side of engine is a black looking plastic set up there is a pipe leading to your air filter set up could be a bit further up than on box take this of and re-route to chassis can send you some pics if like
