I have a 2000 2.7 manual that apparently has the California emissions package. I tried replacing the PCV valve to see if it would stop my rough idle, but as always it opened up a giant can of worms. My pcv valve is threaded in, and I bought the OEM part based on my VIN. The hose that connects the PCV valve to the intake fits extremely loosely on the new valve and I believe it threw a CEL. Unfortunately, I lost the old PCV valve so now I cannot compare the two.


I called a few dealers and it looks like the OEM hose that connects to my PCV valve has been discontinued so I couldn't replace it even if I wanted to. I don't think it would fit on the new valve anyway.


I'm curious if I can just replace the whole PCV assembly with one from the other type of emissions. I believe that PCV valve fits in the cover with a grommet and has one small hose, whereas mine The hose is too different diameters.

Any input? I know the 2.7 is a fairly rare beast around here.

Do You have this?

Unless someone really changed things around, this should be the parts.



Now, the 4cylinder has a EGR Valve on it. Where the V6 does not have one.

My Brother has the same engine in his 2003 Tacoma. So most things should still be available for it..:/

I don't think so, The hose on my 4Runner is larger than that one, and based off of the VIN the part has been discontinued. I would think that my engine is the same as 2003 though, so it should be available. Thanks for the diagram by the way.

All 3rz 4runners have PCV valves. Mine is a federal emissions one and it has a PCV valve.

All North American 4runners have an EGR, but an interesting fact is the Japanese Hilux Surfs (4runner) with the 3rz don't have an EGR. This is why swapping an Japanese engine isn't as simple as you'd think.

OP you have 2 of the same post here. Duplicate posts on the same subject sometimes happens. I would delete one of them though.

Mine has since started leaking now. I sort of feel like taking off the valve cover for other reasons, so I'm not concerned about the old gasket disintegrating into the engine (since I'll remove it).

I did the valve adjustment 1.5 years ago and I bought a new gasket and fasteners, can I reuse the fasteners if they are only 1.5 years old? I know people replace them because the plastic washers get worn, but I don't want to spend the money if I don't need to.
