Ok, so earlier I went to check my oil level (2010 GSR//completely stock) like I do every 200-300 miles, although, this was the first time I'd done it with the engine running. As soon as I pulled out the dipstick, the car began to sputter and idle like crap, I immediately pushed the stick back in and idle went back to normal(ish). I'm going to sound like an idiot/newb here but am I not supposed to check the oil level when the engine is running in a turbo car? I've done it before with all my previously NA vehicles and never had an issue. Afterwards, I turned the car off and waited about 5 minutes before turning it back on. Turned right on, no issues.

I will say this also, after my engine is warmed up, the idle isn't the best in the world. I think I may have a bad vac line somewhere but am not really sure where to start. Should I just take it in to the dealer and have it looked at? Or is it normal. I'll try and get a video of it put up tonight if I can after I get off. The RPM's only fluctuate in about a 50-75 RPM range, maybe at most 100 RPM's at a time. I guess the best way to describe it is like having a slight lope. Yes, the previous owner zip tied the vac line behind the oil stick going to the FPR. Any help here guys?

 

No, don't check your engine oil level with the engine running. The car needs to be off for at least an hour or so for the oil to drain down to the sump. Your car must also be parked on a level surface in order to get an accurate reading. When your engine is running the oil pump circulates the oil to lubricate the engine and turbo and your dipstick might not even register any oil level. BTW, overfilling is just as bad as no oil.

 

Got it, I was always told the engine needed to be warm before checking the oil. You mean to tell me I've been doing it wrong all these years?

Also, another stupid question... Do we ever have to take any action regarding oiling the turbo at all? I feel like such a noob right now...

 

No action is required man. You'll never get all the oil out of the system(oil cooler and turbo feed lines)...just make sure your topping off your filter before install that way your not dry starting the engine. A little over 5qts required for a change...then check...add more if necessary.

 

A little over 5 qts? Is that a joke? My car takes 4.5-4.6 qts.... and it's at full.....

 

About your idle, see the 1st post in this thread

I was looking at that the past few days. This past Sunday I pulled the engine cover and verified that the previous owner zip tied the hose and he did.

 

You created an air leak into your system. Basicly you had unmetered air going into your engine.

 

"Metered air" is something relevant from MAF through induction, intake mani, to cylinders. For correct fuel mixtures.

Dipstick? Not letting air into that system.

The PCV valve is a spring-loaded valve with a specific orifice size designed to restrict the amount of air that's siphoned from the crankcase into the intake manifold. This is necessary because air drawn through the valve from the crankcase has a leaning effect on the fuel mixture much the same as a vacuum leak. So air flow through the valve must be controlled within certain limits. At idle, air flow is reduced because little blowby is produced. When the engine is cruising and vacuum is high, airflow through the PCV valve is at a maximum to purge the blowby vapors from the crankcase.

 

Yeah, you're dead right. I was just coming back to 'fess up with a "duh, PCV". You beat me to it.

General rule of thumb is car sitting for at least an hour and off If you check it when it's running of course you will have oil all over the dipstick seeing as the engine oil is pumping throughout the entire motor. That is impossible to get even a hint at how much oil is in there.

 

Made a Video of my bad idle. Is this normal???

 

Look in your service manual....empty your car takes over 5qts. Given youll never empty tge oil feed lines and oil cooler. 5qts and add if necessary....all im saying
