Question about BMW X3 Series
I have a bmw 318i 2002 plate , it is leaking oil badly , my mechanic has replaced the cam gasket and put a new filler cap on , but oil still seems to leaking from filler cap , he cannot see any VISIBLE leaks any where else , after a few miles smoke is coming from underneath bonnet , ( dripping onto hot engine i presume ) , so cannot have heater on otherwise car smells of burning oil , NICE !!! ,oil seems to dripping all day so may not just be filler cap , any suggestions what to do next to try to resolve problem , apart from selling car , thanks appreciate any advice .
Make sure that the filler cap seal is in place and not gone hard over time also has the rocker cover been off at some stage if it has check that the gasket has not moved the other thing to look out for is that the PCV (breather )valve is in good working order if it is damaged the sump compression will rise and push oil out

If oil was leaking into one or more cylinders the smoke would be blue.

As far as your friendly mechanic is concerned:
It's unlikely anyone trying to sell you a $7,000.00 engine based on what you've described is looking out for interests other than their own.
Ask around, friends of friends, find someone trustyworthy. Get a second opinion, a third. It's a LOT cheaper than a new (yeah right) engine. Sorry about the sarcasm, but how would you know that it was new?

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

Check out this thread and take your Caddy for a couple of Wide Open Throttle runs on the Interstate. Clears out the carbon buildup on the rings that is causing oil blowby.

Hi, its not good news im afraid by you describing that with the coolant cap off and revving the car causes the pressure to build up and push the water back out it sounds to me like the head gasket is on its way out, what you need to do is take it to a garage and dont have a compression test done you need to have a gasses test done, you can buy these yourself if you want to and what it does is this.
its a plastic tube with blue liquid inside it then you take the coolant cap off and place this in its place you then run the engine and rev it up then you squeeze the rubber at the end of the tube and it then sucks the air out of the coolant and through this liquid then if it detects gasses from the engine in the coolant then this turns the liquid green and this is then telling you that the head gasket needs changing.
please dont let it keep over heating as this will cause the cylinder head to warp and you would then need to get it skimmed to make sure its not warped, get the gasses test done as a compression test dont give you a true reading as the engine is not running when they do a compression test.
let me know how you get on or if you need further assistance ok
plz rate this solution as i have a whole page of unrated posts, thanks
