I was told and read that there is a problem with 750 il V12 intake manifold gaskets leaking and causing a rough idle. My car 1990 750il still idles good ( not perfect) and some time I am going to replace the gasket. Has anyone of you done the job. I was told that there is a gasket cement make by locktite that is recommend to be used. What is it? How many of you have done this fix? How did it work out.
