Changed oil and other fluids today.
Wow, the oil flew out of the drain hole. Usually, I have to wait on it to drain but not this time. Oil was very thin and still had the Kreen smell even after burn-off. The oil on the dipstick really darkened up the last 500 miles. So it was definitely time for an OC.
I checked the older PCV valve (replaced about 2yrs ago) and it was a little sludged. Kind of surprised me. Any other time I have replaced the PCV it was always dirty. Not a sludgy slimy dirty but a dry dirty if that makes sense to anyone. Anyway, it does seem to have an effect on the PCV valve system.
Decided to go ahead with a new one instead of cleaning up the old one again. Went to dealership and found out that there is a revised edition for my PCV valve. The new one is just a shell. Doesn't have any spring actuated valve on the end or anything. A smaller hole on the bottom but everything else looks normal.
Interestingly, there had been some confusion from folks I've spoken with regarding the VX model civic I drive. People keep confusing the location of the PCV valve. I think 94 models and onward had them along the Intake Manifold, where as the 92 at least has a valve seated into the breather chamber; which is under the cylinder runners of the IM itself...I found that sucker and pulled it: Slimy goo, nasty. It looks like the original PCV valve!!!
Anyway, using aftermarket Beck/Arnley brand which may/may not be OE, after I clean up some more will check to see if it's crud-filled again. My worries/concerns are if the prev owner allowed the car to get 'bad off' whether the chamber itself has any sludge, I doubt it but may eventually remove the chamber itself.
Depending on how the valve-train looks when I remove the Valve Cover Gasket, I'll know whether I'll use Kreen is this app sooner or later.
