I have a stihl MS 391. I think its 3 years old.
I have had many issues with this saw including the chain not getting enough oil. I have learned to regularly clean the bar channel, clean the chain cover, clean the area where the oil comes out. This has helped a lot. I use a air compressor and blow out all these areas about every 2 gas tanks.
Recently the saw has been leaking oil when sitting. I did some reading I figured the hole where the oil comes out to the bar is probably clogged. So I followed a video which used a air compressor to blow this hole out.
I was cleaning the saw out tonight, and although it hasn't been leaking oil latley I figured I'd blow this hole out as preventative maintence.
Anyways, I put the air compress nozzle on the hole and gave it a bit of air and about 3 seconds later all of a sudden a fairly loud "POP" and oil shot everywhere.
I think my mistake was leaving the oil fill cap on the saw when doing this.
I can't figure out what popped... I wiped the saw down, opened and closed the fill cap and sat it on the floor. A bit of oil leaked out, but I'm not sure if its residual oil from the blow out or I popped something apart.
I don't have bar oil to fill it up (ran out today) so I'm crossing my fingers the pop was the oil fill cap. I can't recall if the cap popped off or not because I panicked and tightened it when the pop happened.
Any idea if I did some damage that I need to fix? If so, what is most likely wrong with the saw?
The other saw I've owned have had a rubber line under the oil tank which carries oil to the bar. I figured that's what popped off, but I can't find the line on this saw.. It should be right under the handle/oil tank if its like the other saws I've owned, but I can't find it.
