Ok, on my 1990 740 GLE non turbo, the repair manual gives a very small picture of where it is. Husband can't find it on the car. Where is it, how do you get to it and do you replace it or clean it?
Thanks again.

If the car is a non turbo like mine. The flame trap is located between the intake manifold and the valve cover. There is a vacume tube that runs out the back of the throttle body to the flame trap, there is another tube that goes from the intake tube around the throttle body and goes to the top of the flame trap.

You can try and clean it with carborator/choke cleaner, you should be able to see through it. If you can not clean it you need to replace it and you can get the whole kit off e-bay if you want to do it your self.

Hope this helps.

i would say dont bother cleaning it, i found after cleaning mine it would be dirty after a month or two again so therefore need cleaning, not only do the crank gasses go up through it, but they condense in it and therefore blocking it.

my volvo specialist just said remove the little colender thing and put the tubes back in place, i have done this and found that some of the smaller (weaker) seals dont leak oil any more due to a lesser pressure in the case.

Don't know what others think, bu this is what i was told and found out to be a good idea.

I would definitely agree that it takes a while to find it espif you dont knwo where or what your looking for... took me and the previous owner a total of 7 years to find it in the end, in this period numerous seals were constantly being replaced due to the higher crank case pressure etc... and resulted in a new rear crank case seal needed to be installed.
