1999 318i Oil Leak

Recommended Posts

What part jonhny?

Anyone beer busy with their 1.9 recently?

Mines running very well as the minute but I have a strange problem with my top hose. When the engine is off it is collapsed, like there's a vacuum in there. Really strange I've played about with the bleed screw but that doesn't help. It's fine with the engine running :)

Not done much. Running well.

Had a roadwork sign scrape down the driver door which has left a nasty mark, but its not that deep. Need to get the scratches on the bonnet an roof done too... im not running out to get it looked at, as im afraid its a full respray job...

Mines leaking water somewhere , not sure where to start looking . .

Check the connecting pipe on the v. back of the block, and the one on the side of the block they tend to go brittle and leak, then check the waterpump n tstat, then the water heater valve make sure the connectors are seated, then check the radiator for bowing, then the expansion tank and connections, don't forget it should leave residue when dried. I've had all ends of problems hope this helps :)

They are very prone to leaking at the very back of the cylinder head. Its a plastic connector, you can feel it but you can't see it without a mirror and light!

I think it's been discussed in this thread somewhere :)/>

Almost all scratches are repairable without a full respray if you have the patience to do it. And if they are only in the clear coat you can just polish them out with a machine polisher.

Packer, I have a thread here with some pictures. I'd like to take this break in the rain to sort it out.

Can you recommend a method and products?

Of course it's hard to say for sure from a photo, but it looks like this is just light surface scratches to the clearcoat.

If that is the case then it can be polished out with a machine polisher.

You would definitely be best using a DA (Dual Action) polisher, since they are easy to use and you run very little risk of doing damage to the paintwork with them.

You can pick up a DA polisher new for £100 or more, or buy a second hand one for £60-ish.

If those prices are above your budget I have also read about people having good results using a random orbital sander with polishing pads attached via velcro. Apparently these sanders have a similar action to a DA polisher, and you can pick up a pretty good one new for about £40 online.

I recommend you do a good bit of reading up on this subject before you start buying products and get stuck in, and the Detailing World forum is an ideal place for that: www.detailingworld.co.uk/forum

To get you started, this DIY guide is essential reading:

And these videos from The Junkman are similarly informative (and also highly entertaining):

Let us know how you get on. Good luck!

I would say so, yes.

If you are not up for having a go yourself then look up a local pro on detailingworld and see what they would charge.

A respray seems like overkill for that damage.

Been real busy recently looking for jobs etc & money has been tight so ive been topping the car up with oil instead of fixing the problem! I've finally got some time to fix it so taken the undertray off & had a look! This is how it all looks , it seems to be mostly oily round the pulleys on the front of the engine & the front of the drivers side of the engine. Im putting around 2 litres of oil in every 3-5 weeks. Heres some pictures . . any ideas? my dad reckons its to do with the timing chain cover & said i should go down that route with a new gasket etc.

Most of that is coming from the valve cover gasket, so do that first ( pretty easy DIY).

Maybe also some coming from the oil filter housing gasket (also DIYable but more hassle to do).

The timing chain cover is at the back of the engine and I don't think it's in any of your photos.

Mine leaks intermittently too, been in the shop twice to be fixed (well first time they kinda cleaned it all up and said bring it back if it still does it) they replaced a few hose,connectors I think, but it still does it. There doesn't seem to be a pattern to it though which is annoying, so now every time I park on the drive I put a tray under the car.

I think its either the oil filter housing gasket or the timing chain cover. Are you sure its at the back? i've been told its at the front? I'm gunna do both & change the valve cover gasket when i put the polishied aluminium one on anyway

The timing chain is definitely at the back of the engine. I think in order to access it you would need to move the whole engine forward. Don't think the E46 is known to commonly leak in this area.

In your third photo that oil residue down the front of the block is pretty much definitely coming from the valve cover gasket.

I thought the timing chain was right at the front of the engine behind timing case(m43 that is)... maybe you guys are talking about a different engine in which case excuse me?

Another thread that I completely missed out on... great read so much info, completely distracting me from work .....

I've done most of this too and still have a rough idle at times but I know from here that there are more hoses to check and over the weekend I noticed cracks in the same pipe you mentioned going from the MAF housing to the fuel injectors.

This is the engine with the valve cover off , shows the chain is at the front?
