Oil light - me again!

Are the plugs full of oil at all?

Does it smoke if on start up you floor the throttle?

Is it puffs of smoke or does it chug out a constant cloud?

Has this garage done a compression test? (Thinking a ring could be burnt out) which could well happen at this stage.

Does it have any overrun? Like in 2nd gear @20 if you come off the throttle does the exhaust crackle at all?

Well I’ve taken it to a recommended Indy who’s first guess was the CCV in fact there was another Z4 on a 03 plate having the exact same thing done! That’s not to say that’s the problem but it’s a cheap/ easy start. Booked in for next Thursday so fingers crossed! Thanks for the advice guys

A fairly cheap diagnosis would be to get a compression test done. That way you would know for sure what is going on. Checking the spark plugs might also give you an indication. If they are very oily and sooty then you know something is going on. But you are not in knackered engine territory just yet.

You can still have good compression readings and burn oil though, if the oil rings or the ccv system are not doing their job the engine could still consume oil.

I think it's a cylinder leak off test anyway for oil burning diagnosis. You're burning a hell of a lot of oil though, CCV would make more sense to me based on quantity of oil consumed.

*UPDATE*

Just had the garage call and replaced the CCV for £93 all in. Smoke has gone slightly but he said it needs a few good runs to get rid of any the oil build up in the exhaust etc but was a great improvement. Doesn't throw blue smoke when giving it the beans now.

He also said the CCV was full of crud so many many thanks for the heads up on this.

Please note this may not be the end of the saga! Only time will tell

Sounds promising though - I hope that's your problem solved.

I collected it this morning and went to a tyre fitter to have 2 new tyres fitted. The costs go on and on to get this right!!!!!

So there was some amount of blue smoke when I collected it. Been to 3 site visits now and the smoke has gone. Had a long blast down the A47 at "speed" and then onto the NDR at speed and no smoke!!!!!

So hopefully, hopefully that is the problem solved

Good stuff. So the garage were at it for an engine rebuild. Gets it fixed for £93 and the guy still thinks he sold you a lemon while slumming it in an MG.

Have you checked for all the usual things that may or may not require fixing / replacing with the mileage of the car? Brake Discs / Pads, Water pump, suspension refresh, bushes etc. Not trying to scare your wallet!!!

Nice one

So after the weekend I report as follows..........................

1. Garage No. 1 I will not be taking my cars back there again.

2. Garage No. 2 has sorted the problem (fingers crossed). Only smokes now on a cold engine start up but no smoke after that. However, the oil light has came back on again along with the EMS light - which sort of goes on and off. This garage didn't top the oil up just replaced the CCV.

So my thinking (I ain't no mechanic) is go back to garage No. 2 and have a full oil & filter change, even though this was done about 3/4 weeks ago. Then I will know where I stand with using oil.

Thoughts?

If it was only changed that recently I’d just top it up, you can monitor the level from there

But how do I know how much to put in?
