Spitting Oil

Post by aphughes » Sat Sep 01, 2012 3:30 pm

So I have the silencer on my 990 and I notice that there is a lot of oil around the top of it.

On the exhaust manifold there is quiet a bit of oil too. She recently had 4 new liners put into her. Is this something to worry about or is this normal after liners have been replaced?

This is fairly common when engines have been rebuilt, your rings won't be bedded in properly yet. Give it some hard work and it will be fine.

Put new rings in a 900 a few months ago after honing. The rings were an excellent fit and this oil coming out the exhaust manifold and exhaust pipe was disconcerting. I drove it to the W.A. tractor museum cuppla weeks ago about 2/3 throttle ; 29km, and by the time I got there the problem had disappeared. Sounds like ring bedding in might be the correct answer
