Alright, so I just did my first oil change on my XT660X and now I have some questions.

I used the Haynes manual and I thought it was straight forward. On my old bike it was a cakewalk so I thought it would be on the XT as well...however.

1) The pressure check bolt on top of the oil filter housing is causing me problems. The manual advices to slacken it to see if oil is flowing (it was) but now I cannot tighten it again. I used a torque wrench to tighten it to the specified 5nm but it just keeps turning. What gives? There is no way I could have stripped it because I barely touched it. When I start the bike, oil seeps out from the screw. Could it be because the washer/gasket was not replaced? The Haynes manual did not mention that I had to replace it.

If I need a new gasket/washer, does anyone know what size/type?
Also would I need to drain the oil all over again to fit it? Im afraid that if I remove the bolt, oil will start pouring out.

And is the bike ridable in that condition? Will it be able to maintain oil pressure?

2) Is it normal that you cannot see the oil level on the dipstick? I poured in 1.9L and then 0.6L as specified in the manual (I didnt change the filter) however, I can barely see anything on the oil dipstick, it only reaches up to the lower mark even after I ran the bike for a minute.

Im really quite frustrated, on my old bike an oil change took 5 minutes but on the XT it seems like a major pain in the ass to avoid getting oil all over. On top of that you need several different sizes of washers and there is no way to check if the bike has enough oil due to the dipstick issue.
