Question:

PCV valve location on 1987 chevy blazer?

I have a 1987 Chevy Blazer with a 5.7 liter 350 engine. Where is the PCV valve located on it?

Answer:

You will find it in a valve cover, PCV valves have been put there for years and years now, and this is usually the first place you should look. If you cant find it then you may need to start googling this one!
My guess would be in one of your valve covers,Look for the black hose hooked to it.
PCV has been in one of the valve covers for Many years.
There will be a breather, and a PCV valve. PCV valve is the one with the hose to the TBI (not air cleaner) and has the PCV valve stuck in the valve cover. Note that PCV valves almost universally never fail, so not sure why you are asking...even one of the GM service manual tests of the PCV is to remove it, and shake it. If it makes noise, it's good.
