WHY IS OIL GETTING IN THE AIR INTAKE IN MY 95 TOYOTA CAMRY


See here p147 for a diagram
http://www.turboninjas.com/camry/eg1.pdf

The PCV valve and hose are on the suction (vacuum) side of the throttle, and this is meant to **** oily crankcase vapours into the inlet manifold for burning.
This should be replaced by fresh air from the upstream or atmosphere side of the throttle, the top hose in the diagram.
When the PCV valve and its hose gets blocked, and the engine is a bit worn, Combustion blow by pressure and oil vapour in the crankcase builds up and is not sucked through the PCV valve. Instead it is forced into the intake tract.
So check the PCV valve, hose, and bleed return hose to make sure they are clear OK. If the problem persists, your engine has probably developed worn piston rings, and blow by is now too high to control properly.

What hoes goes to the crankcase ventilation pcv valve


Hard to say without knowing exactly what vehicle we are talking about..but as a general rule your pcv valve normally has a 3/8 hose that attaches directly to your plenum or intake. It has to be an open vacuum port NOT a controlled vacuum port...if this doesn't help send me the vehicle type,year and engine size and I can pull up the vacuum diagram and send it to you.

I need a vacuum line diagram fo a 1996 Chevy Lumina, 3.1. One line that is not connected to anything, is located at the top of the engine.


Sorry I don't have the diagram, but I do have a diagram of the engine and component locations. Your vacuum system is fairly simple. You have a MAP sensor attached to the air cleaner. I have pasted a picture below. It has one electrical connector and one vacuum hose that goes to the intake manifold or the throttle body.
Behind the right headlight is your evap canister. This will have a hose or line running to the fuel tank. Then it will have another hose going to the purge valve. The purge valve should be close by and it has a connector plus another hose that goes to the intake manifold.
Then you have the PCV hose that goes from the PCV valve in the valve cover to the air cleaner or intake manifold. I think yours just has a hose from the air cleaner and the rest is internal.
There is one more vacuum hose, and that is the bog one that goes from the intake manifold (or throttle body--looks to me like there are a couple of vacuum ports on the back side of the throttle body, and there may be a "T" on one of the hoses) to the brake booster. It this one was off, the engine would not run, as the vacuum draw is large. Please let me know if you cannot figure it out from these instructions and provide a picture, if you can.

zetecvacuumtz6.jpg user_offline.gif If it's equipped with the 2.0L SPI engine (eighth digit of the VIN is 'P'), the most common place for a vacuum leak on these engines, is from the PCV hose that runs from the valve cover to the back of the throttle body. Where it usually rots through is the elbow at the back where it connects to the throttle body. Hope this helps. The only place i could find any views is here. vacuum hose diagram - Focus Fanatics

Vacuum hose missing


Your PCV valve has two port's, it also should have came with a plug ( Plastic ) That you break off of the PCV and plug the small one.Canada Emissions is the only one that uses both port's.

 rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.

With the engine at idle, vacuum should be felt at the PCV valve.
