    On this diesel engine I would say you are building to much oil pressure in crankcase. There could be a few reasons, crankcase overfull, oil filter bypass not operating correctly, or a blow by problem, do you havr oil in the air filter ect.

What would be causing my MF65 to blow diesel out of the dipstick?


If your machine is truly spraying fuel oil out of the dipstick tube, you most likely have some severe engine damage, most likely originating from a leaky (dripping) fuel injector/nozzle. The fact that fuel oil is present in the crankcase leads me to believe that at least one cylinder has been overfueling, causing wash-down of the cylinder walls and resultant piston ring and cylinder wall (or liner) damage. Enough raw fuel is getting (first) into the cylinder and (second) into the crankcase to wash the normal oil film off the cylinder walls, resulting in excessive ring and cylinder wear. In all likelihood, you now have excessive crankcase pressure due to the damaged rings and cylinder walls, as compression pressure is being lost into the crankcase..

Have this engine evaluated by a professional, as a tear-down and rebuild is very likely necessary. At the very least, the fuel system -- injectors/nozzles specifically -- must be investigated and repaired...

How can I stop oil from coming from my dipstick?


Depends on the cause.
Blow-by is when oil blows by the rings in the cylinders into the combustion chambers or compression blows by the rings into the crankcase. It can also be caused when too much pressure builds up in the crankcase because of a venting problem.
So blow-by can cause smoke out the tailpipe from oil burning with gasoline, or oil collecting in the air cleaner, or blowing out a seal or other place like your dipstick tube.
If it is caused by worn piston rings, the rings have to be replaced.
If it is a venting problem, you need to open up the vent, like the PCV valve or the air intake port.
If you remove the cap where you add oil and there is a vacuum when the engine is running, the venting system is working. If oil blows out the hole, there is too much pressure in the crankcase.

Why is motor blowing oil and dipstick out


You have a problem with the rings that seal the combustion chamber from the crankcase .
Try replaceing the PCV valve but I think the problem is much bigger then that at this point its kind of late the damage it done .

How do I check the oil on my Yamaha v star 2000 motorcycle?


Not sure about the Vstar, but pretty much every motorcycle will either have a dipstick or a oil window. Put your machine on a centerstand or have a friend sit on it so it's upright. Look through the window and compare the level to the marks on the crankcase. If you have a dipstick, remove it and clean it. Then obtain your oil level reading by putting the dipstick in the oil fill hole but not screwing it in.

Volkswagen beetle problems


Two possibilities I can think of.. Dipstick not fully inserted... or is it possible that you have overfilled the crankcase with oil??? On my VW, I learned the hard way to take special care when checking the oil level with the dipstick... I had to fully remove the dipstick... clean it off... and THEN reinsert it... and pull it back out.. and then look to get an accurate oil level reading... It must have something to do with how the dipstick tube runs down into the crankcase....

Air in crankcase


is the oil over full ??? then i would suspect a crankcase breather issue which should be in the valve cover... then I would be looking at a head gasket issue, rings or all of the above

I have changed pcv valve twice and still getting oil in breather


The PCV valve does not control the oil situation, it just keeps the pans and valve covers from blowing off during a backfire. Excessive Oil in the breather is a result of excessive crankcase pressures, usually due to a worn engine, specifically rings.
SOME oil is normal, especially if you are loaded heavily and hard on the throttle.
There is a tester that measures crankcase pressures, but usually some other manifestation shows, like excessive oil consumption.

the PCV system draws crankcase fumes into the intake at idle and lower throttle situations. air going into the crankcase is filtered by the small PCV filter, where the oil shows up....

At highter throttle and lower intake manifold pressures, the system reverses, the PCV valve closes, and the fumes exit the crankcase VIA the breather filter. All of this is normal.

It costs tons less to periodically clean or replace the PCV filter.

Location of oil dipstick


There is no dipstick on a Royal Star. To check the oil level, look for a glass window on the right side of the crankcase marked for high (max) and low (min) levels. Get on hands and knees and look under the front crankcase cover directly beside the right operator's footrest; you'll probably need a flashlight to read it.

Do i run the motor before pulling the dipstick on my yz450f


If we are talking about a 2004 YZ450F, you should always run the engine before taking an accurate dipstick check. This is a dry sump engine with the oil stored in the frame. The dipstick is located up high on the frame. You are not checking the oil level in the crankcase as the "Best Solution" dipstick suggested. In theory the oil is held up in thank when the engine is not running. However, most all of them have a tendency to have oil seep/leak out of the frame reservoir down into the crankcase. There is a check ball in the right crankcase cover that usually leaks if the engine has any hours on it at all. The dipstick up on the frame rarely reads accurate unless you have started the engine and let the oil pump circulate oil back up into the frame where it can be measured on the dipstick. Any mechanic who has had hands on experience knows this. The same is true for owners of dry sump XR's and Harleys, who all know to run the engine before final oil check. If you are going to to answer a tech question you need to have some experience with that model instead of your XR80.
