Help!

I have a 220 cdi 2001
I have just done an oil change on this car.Having drained the car of oil I then removed the oil filter I decided to fill the car via the oil filter orifice having put approx 2 litres in I then replaced the oil filter with a new one.
The remaining oil was filled via the normal way.
The car started ok then made a wining noise I cut the engine immedatly.
I looked all around the car then I noticed 3 rubber o rings in the oil filter box,
What have I done as I now realise the o rings are to stop oil from sepping below the filter How do I rectify this problem and have I done major damage to the car?

Please can anybody help

If your oil filter was the cartridge type that fits into the plastic cap then I don't think you have done any damage by not fitting the O rings. You have to remove the old O rings to fit the new so they are still there from the previous filter. It is not essential to change the O rings at every service but it is good practice as they do eventualy harden and fail. Providing you didn't remove the old ones I would leave it alone and remember to definitely change them next time.

I don't know what your whining noise is but on second thoughts it could be worth whipping the filter back out to check all 3 O rings are in place and while it is out you may as well replace them. The big one goes around the filter cap, the medium one fits about halfway along the central shaft and the tiny one fits at the tip.

Hi

Thanks for the reply but I don't think you've understood what I've done, please see bolded text.

I put approx 2 litres of oil in through the oil filter oriface without having the filter in place. It was then that I put the filter back in and put the rest of the oil in.

So basically I've put 2 litres of oil into the engine without a filter.

it should not make any difference at all, if you filled through the oil filter chamber or the top of the engine.

you havent pushed any o rings into the sump or you never started the car with 2 litres of oil in the sump.

so you never replaced the o rings on the filter housing, it shouldnt make such a difference at all, infact any.

did you push the filter into its holder securely!!!, maybe not. the whining could be because its not secure and its the niose of oil thrusting past it.

as I say as long as the oil level is ok, and you havent lost any O rings into the sump i cant see the problem.

oil changes are like changing a fuse in a plug.

ps what oil did you use...and what oil was in before

Maybe I'm being over cautious.The oil that I put in 9 months ago was fully syn and I I have put the same in.
If what I've done should not make any differance what purpose do the o rings do?

Noise was a quick whine but car turned off very quickly.

the o rings are a seal, if the old ones are present i dont see the problem, if the level is correct and the o rings are present, since they were not changed from the sound of things i cant see aproblem

have you tried the car again, is there still a noise

 

[Chris_G]

I do not want to try again as I do not want to do some perment damage.
What purpose do the oil ring serve. If I know no permanant damage will occure then I will try again

 

[Chris_G]

What purpose do the oil rings do then.?
I will not start the car unless I feel its ok
As I believe new engines are not cheap

Hi Chris,
I think you are being a bit overcautious..as long as the filter is in place and you have enough oil in the engine then it should be ok. if i were in your shoes i would start the car and have a general check for leaks around the engine...can't honestly see how you could damage the engine unless there is oil starvation....filling from the oil filter chamber or the filler cap wont make any difference at all as long as you have put in the correct amount of oil..

As long as you have fitted the new O rings and removed the old ones there should be no problem, the rings must be fitted as there are two separate pressurised compartments in the oil filter.

Hi Chris

It doesnt matter which way you put the oil into your engine (either through the filler cap, filter housing or even down the dipstick tube) it will all drain to the sump unfiltered. The oil is only filtered once it is picked up by the oil pump and then passed through the filter on its way to the engine components. I think I understand why you poured some of the oil into the filter housing initially (to try and prime the oil pump?) but I don't think it works that way. If I was in your shoes I would take out the filter and check that the 2 smaller O rings are in place and that the filter is fully home on the cap (it can be a tight fit but I think screwing on the cap would probably push it home anyway). If the larger O ring was missing it would only result in a slow external oil leak which would not harm the engine unless it was run until there was no oil left.

It is probably worth checking your tool kit(including rags) to make sure all is present and correct as there could be something lurking in the engine bay making the noise you are hearing?

Have you spilled any oil on the ancilliary belt which is causing the noise?

If all was well with the car prior to the oil change then it should still be fine if all of the above checks out OK.

 

[Chris_G]

Right, have drained all the oil and put it back in, started the car and the noise was still therem guessed that it might just be the pump going with no oil in it so revved it, seems that the noise has gone!

Hopefully all is well.

Sorry for the re-posts and a big thanks to everyone who replied.

When doing an oil change,the longer you take the more old oil drains from the crankshaft journels and big ends and the gear oil pump, after the change take it lightly up to 1k and the pump will re charge.

Just for interest, on the v8 as from around 99 the crankshaft damper rotates, when you turn off and the drain holes for the oil are blocked, at the same time it leaves the engine retarded, that makes for easy starting. the timing chain tensioner oil way has a one way valve that stops the oil from draining from the feed channel, clever thoughtful stuff.
