Hallo everyone,

My oil sight glass is quite dirty from the inside (I guess).

I can't see the oil level, so I don't know if it is too full...

Whenever the oil light goes on (and it does that just after decelerating, not even when idling) I fill the oil up a bit and then it goes away.


The main leak comes from the pipe going to the engine. you can see it in the pic.

I am thinking of using an oil system cleaner before changing oil and then hoping that will clean my oil level glass.

I don't know if I also need to change some seals or gaskets.

Do you have any suggestions for me or experience with the same problem?

edit:
that's the front cylinder head oil return tube. I don't know if the O-ring needs to be changed. Does anyone know how to do that?

I would drain the oil, change the filter, put in 4 quarts of 20w50 oil, and some Seafoam. Seafoam has worked for me before for cleaning oil sight glasses. Oil that is too thin can cause low oil pressure, though a worn engine with loose bearing clearances will also cause a drop in oil pressure. There might also be a problem with the oil pressure sending unit. If the engine has not been properly maintained, and has sludge in it, the oil pressure sending unit could be full of sludge. I would remove the sensor and use some spray brake parts cleaner to try and clean it.

Is the thicker oil also part of the recipe or is it only the oil that you usually use? I normally use 10W40.

i will change oil filter and all. Are you suggesting to leave the Seafoam in the system? and not drain it afterwards?

I got the Liquid Moly engine flush shooter and that is not supposed to be left in.

The sludge in the system could actually very well be.

judging by the picture I sent, do you reckon I have a lose seal, or is it just overfilled?
