Usually replacing the PCV valve on most engines is a ten minute affair. I spent almost an hour removing the heat shield before I realized this job required the thermostat block and many hoses to be removed. What a freakin' $#@%%^&*. Could they have put this in a more stupid place?

Anybody have a better method of getting to the Zetec PVC valve?
 
The zetec thermostat housing gaskets love to leak on these cars, so why not pick up a gasket, new t-stat, and pcv valve, and do it all at once?

I should add, it's where the thermostat housing meets the head that leaks, not where the thermostat is sandwiched. But thermostats are cheap, and a good routine maintenance item if you're interested in fuel economy.

i agree with this, and probably should do it myself haha.

Mine doesn't, but I already have a few spares laid in for the next time I pull it. Since it comes off for almost any work in that area of the engine, and now include PCV-valve changeout to that list, it helps to have a few spares.

250K miles and mine never once leaked. never replaced the gasket either.

pretty sure my doesn't either at 228k. although a few years ago over one very cold winter I did discover some antifreeze leaking in that area, I was never able to pin point where it came from. plus it hasn't done that since.

Same here...
 
That's crazy, around here they all seem to leak. It's such a common problem that there are aftermarket manufacturers that now make an improved housing to prevent that problem. Mine leaked, I replaced the gasket, it was fine for two years, and then it leaked again.

You guys must just be lucky.
 
I have 300k km on my cougars zetec and the t-stat housing doesnt leak. It's used orange coolant its whole life

I was also able to change my PCV without taking anything off. I Have a weapon R header though so I get more room to work. Agreed; its a PITA
 
The good thing is that the PCV is all of $2 plus tax.
I spend more than that each day at the vending machine.
