Short journeys don’t explain the disa valve covered in oil, it’s still a ccv issue imho.Rachel!!!! wrote: ↑Fri May 28, 2021 8:31 pm Sorry for the delay it's been a busy week.
I spoke to a bmw specialist last Friday, he suggested that if the soot on the bumper is watery and not oily it could just be a condensation issue. He said once condensation has built up from short journeys it's then very difficult to get rid of.
The disa valve was missing the pin and stuck in the open position, this has now been replaced. The mechanic said to change this and see if there was any improvement and go from there as he said it could solve the problem. I'd already ordered the part and my friend did this along with an oil and filter change which has stopped the noise on the oil filter. The noise was only present when revving the engine not at idle.
The oil from the filler cap couldn't be seen until we took the engine cover off. I'm going to check it again tomorrow to see if any has come back since the oil change.
So at the minute it's still up in the air. But I will update again as and when I get anywhere.
Thanks for the offer of help, that's much appreciated, I will be in touch if needed. I was thinking of getting a mechanic onto the job if it is the ccv as it seems like quite a big job taking everything apart to get to it.
