200tdi oil level


trojan

Recommended Posts

i've got a couple off questions to ask and the first one has me stumped .( i'll post the other question later ) a couple off weeks ago i noticed that my oil level had gone up and seemed a little watery , so i assumed it was the lift pump that was faulty and changed it for a new one , gave it a good service ( oil ,oil filter and for good measure i fitted a new fuel filter aswell ) . and due to the fact i check my oil level every couple of days i assumed there was no damage done . all was well until i checked it today and saw the same thing . :(:(

the engine doe's not appear to be breathing either through the oil filler cap or the dip stick but there is a little bit of oil on top off my rocker cover ( not loads, but it is wet ) . the engine doe's not smoke either on start up or under load and it's not using any water . my question is , is there any other way for fuel to get in to my engine oil or is it possible i've just got a duff lift pump.

bye the way the engine performs as normal and doe's not appear to be using more fuel . and it's a defender with a disco 200tdi conversion .

Could be a dribbling injector that's not shutting off correctly & allowing fuel to get past the rings, possibility of a new duff lift pump, there's not much else that would let fuel into the oil, oil on the rtop of the ocker cover could be coming from one or more of the attachment bolt grommets.

someone else said that today but i've never heard of it before so i dismissed it ( i guess i'm wrong ).

how would i check which one it is ? and would'nt that make it difficult to start and or smokey on start up ??

and i've just thought , it's oily around number one injector , could it be it's broke that copper seal thingy at the bottom of the injector and its not burning the fuel ???

forgive any stupid questions i could post as i'm not big on diesel's just yet , i grew up working on petrol engines and i'm having to rethink stuff .

If one injector is suspect, then I'd suggest removing all 4 & having them tested by a diesel injection specialist, you'll find some in your phone book under -- diesel injection or similar wording. [be prepared to buy new or rebuilt injectors]

as a example I had my 4 tested 3 were under working pressure & dribbling/not shutting off correctly & all had cracked nozzles but it still seemed to me to drive OK, but much better with new/rebuilt injectors fitted, not knowing your engines mileage but if over 100,000 it'll be a good move.

possiblby the copper seal washer the injector sits on is either broken or missing.

got the injectors checked and cleaned and was told by the engineer that they were all slightly below spec but none of them was dripping , he has rechecked them all and they have been given a clean bill of health .

while i was replacing then i noticed something that could be the reason for the oil level reading and i would like your opinion .

the engine in my motor is from a discovery , and when you fit them , as your probably aware , you have to extend all the hoses including the oil cooler hoses .

while replacing my injectors i noticed the hose that goes to the bottom of the oilcooler looks like it could be to long and "DROOPS " quite a long way below the level of the oil filter housing and the oilcooler . i'm now wondering if there was still oil in the hose when i last changed it . i know it may sound far fetched but i cant for the life off me think of anywhere else it can be coming from .

remember i've already replaced the lift pump with a new one , and i now know it's not the injectors .

ohh and i asked my m.o.t fella what he thinks and he's sure it's not diesel in the oil as the smell shoud be quite strong .

i'm open to all opinions and ideas , cos i'm no diesel expert as i grew up messin with petrol engines

don't think it would cause any problem, it would only be a small amount of oil in there not enough to drasticaly alter the oil level in the sump, one other thing to check is the security of the oil dipstick tube, sometimes they work loose [the small olive on the bottom loose's it's grip] & can let the tube move further into the sump thereby making you think the oil level has gone up -- when in fact it hasn't, you can retighten the olive by reflaring the end of the tube with a taper punch, did it to my 200Tdi[defender version] a while ago.

that's good news about the injectors, at least you know their OK :)

still , i think i'll shorten the hose just to make sure .

i'll check the dipstick aswell , but from memory is'nt there a bracket holding it to the engine , would it still slip ??

Yep, the olive is on the tube but inside the big nut that secures the tube to the block, LR issued a tech bulletin sometime ago about this problem

i'll check it tomorrow , i'll do my nut if it's that cos it's just cost me £50 for the injector clean , and thirty quid for oil and filter " again " , i'll rip the bugger out and tie it in a knot :angry:

the tech bulletin info ------------

thanks for that western , i'll check it in the morning and let you know .

part of my problem is that i get paranoid about oil and water checks and i tend to notice changes pretty quick . could be because i'm drive wagons for a living and it becomes second nature to check .

i'll let you know tomorrow .

thanks again.

edited to remove the images as their above anyway

ok , i've put the injectors back in give it an oil change , run it around for a day or two and all is ok !!!

the only thing i can put this oil level thing down to is operator error ( cough , cough )

maybe a good example for checking your oil as often as you can cos you never know .

Good to read everything is OK :i-m_so_happy:

Best tell the operator to buck up or he's sacked :hysterical:
