Sorry for all the questions. But here is another.
The hoses that make up the breather system run from the valve covers and one from the crankcase. They meet and then enter a plastic cylinder.
My question is this: is there a diaphram inside the small plastic cylinder or is it hollow. The reason l ask is my breather only has 40,000 miles on it and is not plugged when u blow air into the various ports. I have to replace my valve covers but if the breather hose is ok l would just leave it alone and change the suction pump and non return valve.
thx peter
