4 cylinder or 6?


The PCV Monitor consists of a modified PCV system design. The PCV valve is installed into the rocker cover using a quater-turn cam-lock design to prevent accidental disconnection. High retention force molded plastic lines are used from the PCV valve to the intake manifold. The diameter of the lines and the intake manifold entry fitting are increased so that inadvertent disconnection of the lines after a vehicle is serviced will cause either an immediate engine stall or will not allow the engine to be restarted.

I have a 99 mercury cougar 2.0l it's burning oil threw the intake manifold I've replaced the pcv valve but it continues to draw in oil and blow out thick white smoke out of the exhaust if I clean the...

That is not supposed to happen. Oil being sucked into the intake manifold. Ever. You have something hooked up wrong or not even hooked up. Be sure the line from the PCV in the valve cover is hooked to the breather case, NOT vacuum fitting on the carb. Run a full breather also, nothing missing.

It started about one week ago my 96 mercury cougar XR7 won't go over 35 mph it just revs to about 3000 rpm. I replaced the pcv and had a complete tune-up, also checked the transmission. What could...

If it revs up & doesn't go,the trans is slipping
& will have to be rebuilt

Not going over 35 with no trans issues would
be a bad exhaust converter (blocked) & or
a clogged gas filter

Tune-up is sort of a outdated term and never
is a cure for much ,unless you have ignition issues

Never have to replace any PCV Valves. Remove & clean
every 3 years

You have a vacuum leak. Check PCV hose on passenger rear of engine. Stuck open EGR valve can also be the cause.
