I am an independent automotive diagnostic, restoration and repair technician, and have never been more satisfied with an online parts distributor. They have the most extensive catalog of parts, the best prices, and the most accurate service and shipping I have encountered. 5 out of 5 stars. Thanks RockAuto!

Repair Mistakes & Blunders
Repair Mistakes & Blunders

In college decades ago, a buddy let me drive his 1st generation RX-7, and I knew then that a Mazda like his would be my first “real” car. I found a well-kept and nearly blemish-free RX-7 and handed over a significant chunk of my meager savings. I preened over that car, and one day over a long weekend at my parents’ house, I set out for a full day of driveway detailing including door jambs, drip rails, engine compartment, everywhere. For extra credit, I even washed and waxed the big blue air cleaner cover that umbrella’d the pony-keg shaped Wankel engine. Finally satisfied with the work, I unpropped the hood and let it fall closed — but the hood did not quite latch. I raised and let it drop again; then again, this time from a little higher.

Hmm, why would the hood latch not close? Maybe the hood latch receiver somehow closed during the servicing? Nope, it looked “open” and ready to receive the catch. Maybe the latch was not closing over the hood catch, but that would not explain the gap between the hood and front fender.

After opening the hood once again, the culprit revealed itself: my can of paste wax resting on the air cleaner. After removing the can of wax the hood closed easily with its familiar "thunk." But now four tightly-grouped convex dents dimpled the center of what was, only moments ago, a pristine hood.

That day of personal infamy still serves as a reminder that even doing something as simple as a good cleaning warrants a thorough post-job inspection of both the car and the work area.

Answer below

PCV & Oil Separator Systems
Tom's Story

Since the 1960s, the Positive Crankcase Ventilation (PCV) Valve has kept clean air flowing into the crankcase while venting fumes and excess pressure into the engine's air intake; protecting both the engine and the environment. A clogged or leaking PCV valve causes oil leaks, oil consumption and/or oil smell. PCV valves should be replaced before they wear out according to the vehicle manufacturer's recommended maintenance schedule. The same symptoms (oil leaks, consumption, smell) can also be caused by a bad Oil Separator; a part on newer engines that you may not be aware of.

PCV system designs have always tried to keep excessive oil laden vapors and splatter from reaching the PCV valve where it might pass into the intake. Old engines might just have a plate mounted below the PCV valve opening in the valve cover that acts as a simple baffle. On many newer engines, more complex baffles on the inside of the valve cover collect oil droplets before they can reach the PCV valve opening. Some modern engines, especially European brands and European-influenced engine designs (e.g. Jeep 2.0L) have a separate part called an Oil Separator to keep excessive oil away from the PCV valve.

Keeping the oil in the crankcase and out of the intake is both more difficult and more important now. Newer engines may have lower friction piston rings to increase fuel economy. That allows more blow-by from the combustion chamber into the crankcase; increasing the pressure and volume of gasoline fumes, water vapor, etc. that must be expelled through the PCV system.

Oil that escapes with the fumes into the intake may lead to significant oil consumption and troublesome sludge/carbon deposits. Today's gasoline direct injection (GDI) engines are especially vulnerable to carbon deposits on the backside of intake valves because gasoline may not be able to wash it off. Increasingly common turbochargers/intercoolers can be clogged by oily sludge as well.

Oil Separators may appear to be nothing more than passive plumbing, but a lot of thought went into designing the plastic boxes, baffles, tubes, etc. so that oil residue has time to fall out of the PCV vapor stream and has a path to drain back into the oil pan. There may be open space so gas pressures can drop. There may be sharp bends so the oil residue can hit and run down a wall. The Oil Separator for the BMW 3.0L L6 (see photo) is a good example of complex twists and turns.

There is usually nothing high-tech about the way Oil Separators fail. Heat, vibration and oil exposure can cause gaskets to leak, plastic housings to crack and hoses to disintegrate; resulting in oil consumption, leaks and/or smells. The difficulty of replacing an Oil Separator varies a lot between engines; depending on how many other parts must be removed to gain access to the mounting bolts and hose clamps. See Oil Separators and Positive Crankcase Ventilation Valves for specific vehicles under "Exhaust & Emission" in the RockAuto.com catalog. Valve Covers (that on some engines includes plumbing that acts as an oil separator) can be found under "Engine."

Jason's 1972 AMC Javelin
Jason's 1972 AMC Javelin

This is my 1972 AMC Javelin SST 401 that I have owned since 2002. I recently finished a complete nut and bolt restoration spanning over 18 years. That's right, not a typo! I completed the restoration myself little by little (except for body and paint) even during multiple job transfers and relocations. The Javelin is part of our family and has been with us every step of the way! Purchased as a "garage find" with low miles but in rough shape, I managed to slowly restore the Javelin to the show car quality it deserves. I have always been fond of AMC vehicles having grown up with multiple models in my family. This Javelin has the 401 cu. in. four-barrel engine with an automatic 727 three-speed transmission and Twin Grip 3.54:1 gear ratio. AMC Trans Am Red adorns the exterior while the interior sports the rare Pierre Cardin design package.

Although many items are somewhat difficult to find for these cars, I was absolutely impressed with how many replacement parts RockAuto offered for my Javelin. From engine to suspension, I was able to easily find and order a multitude of parts such as belts, filters, gaskets, shocks, suspension bushings and various rebuild kits to get this rare car back on the road. Thanks to RockAuto, my dream of restoring this AMC to showroom condition became a reality!
