SOURCE: 1965 ford 352 engine blows oil out of breather.

I know the 65 didn't come with a 352, what is a 352? I thought it was a 351 windsor,? Anyway, did you rebuild the motor? There is a vent under neath the intake sheet metal that clogs up, It is held in the with a plate and rivets, you either have to remove the rivets or soak the whole thing in solvent. It will upset the car's pcv, a new pcv valve won't hurt, you don't need to be drilling holes, you might make it worse. Check all your vacuum lines. Make sure you have no leaks. Hope this helps.

99 Chevy Malibu 2.4 engine. I check my air mass sensor and it was covered with oil and I see that I had oil in the combustion chamber. How to get out oil

Oil is coming from pcv or breather pipe. You probably have excessive piston ring wear causing blowby and forcing combustion gasses up the engine and into the breather and pcv system. Oil will come with the gasses if not filtered out. Check the pcv valve for proper operation and check any breather cap for baffles to keep the oil in the valve covers. Also consider getting an engine rebuild, if you want to keep the car.

Location of pcv valve 95 nissan KA 24 engine hardbody

Follow the breather hose(s) to where they meet the engine and that is where the pcv valve is usually to be found if your engine has one; valve cover, crankcase or inlet manifold are the likely locations.

Not all engines use a pcv valve. Many engines just have a tiny hole into the inlet manifold which typically soon blocks and needs cleaning.

Ford was one of the manufacturers who in the early days of a pcv system being required, used an oil filler cap to attach the breather system to and the tiny hole was inside the cap along with the flame trap and oil mist filter.
That like many of the plastic pcv valves was intended to be a throw-away item.

I hope I have helped you a little.

I have a 1978 Cj5 Jeep with a 304 V8 in it, so I have two questions.One is, the pcv valve in the back of the intake where does the hose coming from the pcv valve go to? The second is the hose on the oil...

The PCV valve hose runs from the manifold to the filler cap. It is there to suck the combustion pressure out of the sump on throttle manuplitation

Bmw 318i oil leak

make sure that the filler cap seal is in place and not gone hard over time also has the rocker cover been off at some stage if it has check that the gasket has not moved the other thing to look out for is that the PCV (breather )valve is in good working order if it is damaged the sump compression will rise and push oil out
