Hi I just bought a Honda pressure washer. The instructions tell me to replace the travel pump plug with the supplied vent plug. I have done this but when i run the washer oil spits out of the vent plug. The washer now needs more oil. Should i put the travel plug back in? Please advise?

You just bought it which means it is under warranty. Take it back where you bought it or call Honda. You must have the vent plug installed to use the machine. If it is blowing oil out the vent plug then it is either overfull or it is building up pressure for some reason. Make sure it is not overfull and if not, then call Honda and avail yourself of the warranty. If it is overfull, remove enough oil to get it to the proper level.

Its just plugged up, probably right at the nozzle it's a pretty tiny hole. To clear it out you need to find a small diameter wire that will fit inside the hole to clear the blockage. Something like a small gauge sewing needle or a straight pin. It can also get plugged up in the rubber tubing. Usually you can just blow through it with lung power. Just pull the tube off at the nozzle and run the washer this will tell you if it's the nozzle or the tubing.
Take hose and gun off pump. Start engine. See if pressure comes out of pump. Next, remove water hose and look at filter washer. Clean or replace filter washer. Turn on water and it should come out of pump on other side. These steps will tell you if problem is water supply or pump.
Sometimes the problems happen because the gun lever is bad. Hook up hose but not the gun See if pressure comes out hous. These steps will tell you if problem is gun or hose.
Were I to pick from one of those three, I would pick the Landa. The most reliable pumps are Hotsy and since Karcher bought Landa and Hotsy, those three brands now have Hotsy pumps, though it doesn't say it on the machines.
The oil will be in the stainless steel or silver colored part of the pump. If there is no access to this part then the oil is put in there by the manufacturer. I believe the small red plastic plug you speak of covers the overheat blow off valve. Just leave it. When you run the washer for a long time you may see some water spill out of there. The only way to change the oil is to separate the two pump sections. Not advisable without some knowledge and the correct tools
The pump oil reservoir and pump pistons are between the Honda engine and the business end of the pump. It rarely brass, like the pump. It may be square or tubular.
Some of these units have a site tube on the side, some don't. Some have an oil drain plug (bottom) and a plug to put oil in (top). If not, you have to take the pump off. Either way, be sure to use NON-detergent oil and only fill it about 1/3 to 1/2 full.
