Can no oil cap cause rough idle?
If you remove the oil cap, you allow FREE UNMETERED AIR in, which is then sucked into the throttle body, messing up you air/fuel ratio, then causes the computer to adjust timing and fuel output to compensate. Yes, any time you step on the brakes, the engine idle goes up just a little for a similar reason.
Why does my car have smoke coming from the oil cap?
There are two main possible reasons why your engine will emit smoke from the oil cap: You should be aware of the fact that the specific amount of tolerance between the engine components determines how smooth the operations of such an engine will be at any given time.
Why does my car shake when in idle?
After having my car serviced for oil change, tire rotation and air filter replacement, as I was leaving the service center my car had a new engine vibration/shake while in park or neutral in idle. If I rev the motor to 1000 rpm the problem seems to go away. I am not getting any engine codes.
Why does oil come out of the oil cap?
You should be aware of the fact that the specific amount of tolerance between the engine components determines how smooth the operations of such an engine will be at any given time. To keep all the parts moving smoothly without friction, the oil just has to flow to all the parts of the engine.
Why does my car idle rough when I pull the dipstick?
Pulling the dipstick or oil cap relieves the pressure, but lets unmetered air into the intake causing rough idle. Normally I’d say you have a problem in the PCV, but it sounds like you’ve done all that. So, I’m guessing worn seals.

What causes oil to squirt over top of engine?
The squeak is the dipstick not sealing properly. I’m going to guess that one or both of the O-rings on the bottom of the dipstick are cracking. If they were broken you’d have oil squirting over the top of your engine. Loose spark plug (s)? In short, the crankcase is part of the PCV system which is tied to the air intake.
Why does my car engine run rough while idling?
When your car engine runs as it should, everything should be smooth without any noise. When any number of things goes wrong, the engine can start running rough, especially while idling. By understanding the causes of a car engine that has a rough idle, you can resolve the issue easily.
Why does my engine squeak when I change the valve cover?
While searching the forum, I came across the PCV valve issue threads so I’ve since replaced the valve cover thinking it was the PCV valve, but again, the squeak is still there. I then did the PCV valve/Intake manifold mod, and again, it’s still squeaking! Also while having the intake removed to do the PCV mod, I also ported the intake manifold.
