wr400 oil coming out of top of engine

4 posts in this topic

I have a 1998 wr400 ran fine sat for about 9 months then started and ran and oil was coming out of top of engine, under tank where you can't see it. it runs fine just I haven't because i don't want to seize engine. what would be most likely reason? a gasket?

Simplest thing would be if your breather hose got snatched off. How fast is the oil coming out? It's it just a leak or an actual stream?

If it's like mine (I know the 426 engines are, not sure about the 400's.) then it's a regular black hose you'll find just behind the left radiator. It runs up to a nipple right on top of the cam cover. The hose is about 1/2" in diameter so it's hard to miss.

It sould like it'll be easy to find, just give it a good bath and fire it up then just watch for the oil to run out.
