possible oil leak

[mikemike]

on a 1991 318i I spotted what looks like and oil leak coming from where the air inlet joins the inlet manifold , doesn't smell of fuel so just wondering what it could be

what you mean the throttle body ? which joins the inlet many fold

where ?

if you follow the air pipe from the throttle body to the inlet manifold it seems to be coming from there , we only spotted it as it looks as if its running on the cable that runs between the throttle body and the manifold

thats the breather pipe from the rocker cover , probably split . you needa new pipe. blow by gas which contain some oil mist are being sucked back into the inlet manifold to be combusted , and can form oil droplets inside the pipe . if its the pipe i believe your referring to. a photo would help .

I thought it might be something like that , will strip it down on the weekend for a better look
