problem with oil leaking

[daemon982]

hi

I have a problem with my vitara engine 1.6 8v carb (G16A)

I attached some pictures:

this is were the fuel line in is and under this line is a hole, where the oil is spitting out off, can someone help me, why this is happening?



this is the hole, where the oil is coming out of.

Hard to tell where that hole is but it looks like it's missing a bolt. Put one in.

that's the vent for the fuel pump. Oil leaking from there can be a sign of a build up of positive crankcase pressure. Could be a blocked PCV valve.

Either that or its actually a mix of fuel and oil, meaning it's the daiphragm that has a split so a new fuel pump is needed.

there is no mix of oil and fuel just oil coming out.

I thought there was a seal between the pump and block. Maybe that has gone?

[ScottieJ]

The fuel pump gets a small feed of oil through the push rod hole off the cam for lubrication.

I would check the PCV valve is working and if that's ok then it could be a worn seal on the diaphragm lifter rod.

First i will check PCV valve, this is the easiest fix, if this is the problem.
Will report back to you.

I have cleaned PCV valve and seams that that have solved the problem.
