Greetings, I just picked up a '06 Focus Wagon, 2.0 Duratec/manual tranny, 89K on it--private party. Oil changes every 5K, one wheel bearing replaced, front rotors and pads--no other maintenance. The car was garage-kept, looks great, drives great. So, far I've changed all of the fluids (coolant/PS/brake & clutch/MTF), changed the plugs and cleaned the engine. Funny aside, I asked the owner (self-professed car guy who did his oil changes and the brakes) if the transmission fluid had been changed. He looked at me funny and told me it was a manual, so there was no fluid... Everything else checked out, so I just let it go and told him I thought there was some fluid in there somewhere... Other aside: Ford's million dollar synthetic MTF looks great @89K, and I noticed zero difference in shifting after changing it. I'm very impressed w/the fluid, and felt less bad about the $13.XX a quart price after changing it! So, last maintenance item before I begin dismantling the interior for the big sound deadening project: the PCV valve and hose. I know these are prone to cracking (the hose) on this engine. Is there any way to actually test this out, say with a mamometer or something? Before anyone chimes in w/"just change it", please understand it's not that simple--the IM has to come off. I'd really prefer to wait until the spring, mostly because I just changed the oil and after pulling the IM my OCD would require me to change it again. Plus, if it's intact I'd just as soon wait. I do have the parts on-hand already. I've not experiencing any idle issues/error codes, or hissing noises, but if there's dirty air being sucked in there I'd like to get it changed. Anyone have any knowledge on how to actually test the system? Thanks!
