Hello all.
just a quick question that im sure u guys can answer quickly..
my brothers feroza is starting to run a bit rough...
i pulled off this hose to find it full of a black oily substance.
1. Is that normal
2. what does this hose do.
Is this a sysmptom of a blown head gasket?
Thanx all for your time.
Adam
It looks like you have just removed the breather hose from the rocker cover to the throttle body, this will get oil thrown into it by the moving cam shaft and rockers, etc below it. They use this method to plumb a breather so there is no place any water can get into the block during a water crossing which as you would guess, could be terminal.
In short, that is natural to get oil into that hose from the splash of the engine. But not heaps of it.
If your brothers Roza is running rough, I would recommend checking the vacuum lines (if it has them), base idle, timing. Else try a major service, oil, all filters, belts, valve clearance, spark plugs and leads.
This gets me out of trouble most of the time but I tend to go over the top and check everything.
