Hi,
About a month ago I was in London traffic and noticed some smoke/steam coming from the passenger side of the engine bay (RHD car) - it would come out of the corner, near the wiper, where the battery is in the engine bay. I wasn't sure if I was imagining it or if it was the exhaust fumes of the car in front! It was not constant, extremely intermittent (I haven't seen it in a month) so I'd catch a flash of it then look, and it might be gone, or carry on for a couple of seconds.
I got home and looked and the engine and the only thing I found was some vapour and a leak from the PCV, which is on the other side of the engine. I have now replaced that, no more leak from there - although it was a different kind of 'smoke'/vapour coming from there, much thinner.
However yesterday, in traffic, I noticed a bit of smoke/steam/vapour coming from the same spot (passenger side), much to my annoyance.
Does anyone have any idea on what things to check for? I can't see anything really obvious in the engine bay, but I'm still new to this engine and I'm not sure where everything is located
The only thing in the actual engine bay over that side is the EGR valve - is that something that could do this? I can't see anything near the battery (cover still on).
Cheers for any suggestions!
