Thank you one moment...
You sure you used the correct pump oil? You sure you didn't overfill it? , overfilling I believe could lead to foaming and poor lubrication. If your sure on those drain the oil and look for water, maybe a seal is bad and water is getting in the crankcase.Let me know if there is any water getting in the oil.ThanksTech Michael
I happen to have the same one lol!I had a similiar problem with my pressure washers pump oil cap. I had just replaced it for my residential house wash pressure washer because it was gushing oil.

The oil is not discoloured
Thanks that good ;-)
There are a few things that will cause this problem, if no water is getting in the oil that's great news. so its either a bad cap, or cap seal, or its filled too full or not enough, and the only other issue woudl be if there was air in the system.I would drain and re fill the oil and make sure the cap and the seal for it is in good shape and that there are no cracks in the threaded hosing where the cap fits the unit;-)Thank youTech Michael

Is there anything in the cap like a valve eat as I can only see day light through it
Customer: replied 2 years ago.
Regarding the oil I've been about today and the only place as I was told it was milking machine oil
Hi, no there is nothing like that in this cap
Its just hard to seal sometimes, try a new seal, but first I woudl drain all the oil out to be sure its not getting air bound which woudl definitely cause this problem.

It's a red cap with a hole through the middle of it and the oil is coming through the hole
Hi yep I knwo it well ;-)Is the oil coming out that hole, or around the seal?
Customer: replied 2 years ago.
Out of the hole
Hi I would try a new cap, there is a seal in that one that seems to have failed.
Its not a valve but a seal, that will blow if the pressure gets too high due to air in the oil. That can happen if its tipped or layed on its side. The solution is a new cap and replacing the oil after emptying it out fully.

whats inside the cap to stop the oil from coming out of the hole
Its just a seal in there lol. But once it blows, the cap needs to be replaced with a new one is all ;-)Im sure thats all you will need;-)Please rate my service at this time so I can stick with you until you are sure that worked;-) no cost for that and then I can place your question in my priority list, so when you write me I will see it ASAP.ThanksTech Michael
