Hi guys,

I was talking to a buddy today and he told me something I have never heard before. He said his Inline motor was smoking after only 5,000 miles and his mechanic told him that his motor needed umbrellas inserted. His Vacumn and compression are fine but the mechanic told him that the oil was leaking down past the guides and that "Umbrellas" would fix the problem. He said that this is a common problem with inlines.He said it took a special tool that blew air into the cylinder(to keep the valve from falling)and then they could insert the unbrella and that would keep the oil from draining back.
Has anyone heard of this before? Is it the same as new valve guides? Why wouldn't new and tighter valve guides work?

Thanks.
