Topic: Help! Oil shooting out VC PCV Tube at WOT!

Change your oil,  check the smell after about 300 miles,  if you still smell gas, replace your HPFP

I probably will after this, but I'm just happy to have fixed the biggest problem for now.  I'm still going to have to flag down the issue with the oil vaguely smelling of gas, but I don't I'm just happy I got the major thing fixed at the moment.

If you've got fuel in the oil, you've maybe just put a bandaid on the problem vs. fixing it. Treat the disease, vs. throwing parts at the symptoms.

I'm going to have the oil changed in the next day or two. 
The one thing I didn't think about is the fact that I haven't smelled the dipstick prior to last week since the oil was changed in May. The car had a number of 2step launches in that time which cuts spark but not fuel.  Perhaps some gas got into the oil from that as well.

Gas should not get in the oil because a spark is not firing unless issues in the rings, gas should go in the exhaust in case of misfire/2step.

Exactly. Which would be another reason to run a compression test.

Are you trying to bankrupt all dealerships???
I swear this is how they deal with most stuff they get.

Yup
This is how you tune a car to get the pops and crackles when you let off the gas or downshift off gas.
The Jaguar F Type has this from the factory.

A decent tester is fairly inexpensive and the process is as easy as changing spark plugs.


Your car has been run harder than an Epstein hooker, and then put to bed wet.   It probably would be a good thing to test.

Throwing parts at a problem and expecting a solution is a pet peeve of mine. Not just because some techs try BS like that in my building, rather it's mostly because many "mechanics" deride home mechanics like me for doing this. (All while most mechanics in the area don't even understand basic troubleshooting concepts...)

+1. I think the time has come to invest in some serious troubleshooting to determine the root cause of this car's issues. When modifying a car, causes of problems must be determined. Why did it go lean?

Here's an example: Say you put a new intake manifold on a hypothetical car, and now it runs lean. Not enough to be a knock hazard, but lean enough that it's on the edge. Was it the better airflow from the new intake, or did the injectors top out? If you assume that it's just the airflow and throw on a canned tuned to fix it, this engine could then turn around and shit its guts out when you find out after the fact that while airflow was part of it, really the injectors couldn't keep up.

That's all hypothetical, and not likely, true, but that's why investing in troubleshooting tools is even more important than investing in speed parts.

Well you guys are going to hate me, but I was talking to an engine builder friend of mine and he ran a very easy test on it....Basically, if there is more than 2.5% gas in oil the easiest way to tell is to pull the dipstick and put a lighter to it.  If it lights up at all then there is definitely too much fuel in your oil, but if not it's fine. 

Mine didn't light up at all even after multiple attempts.  I think my nose is too sensitive because I smelled the dipsticks of my wife's car and my neighbor's and they both smelled like fuel as well to me.  My friend told me that generally it doesn't take much fuel to make the dipstick smell that way, and they almost always smell fuel on oil dipsticks when the vehicles have over 50-60k miles on them.  It's just a typical thing.   

That said, as a precaution, I'm having my oil changed on Monday to Mobil 1 high mileage.  I'm going to drive it for a bit (300 miles or so) then if the smell doesn't return I'm good, but if it does I'm going to have it compression tested.

After speaking with Dave from DDM it all really does make sense to me.  Yes I took that PCV off two years ago, and no oil shot out.  Since I've owned the car it's had that weird hesitation I've described even when the tune.  Dave asked if I upgraded the power level of the car lately, and in fact, with that CEL for the MAP sensor my car pulls very hard now all the way to redline, so I essentially did add a lot of power to it.  Once I described that to him he definitely thought it was just because of the added pressure after 5,000 rpms that pushed the oil out the hole (no baffling in the valve cover). 

To the fuel in oil issue, that oil shooting out the hole was the first time I had actually smelled my oil, and I think I may have over reacted because I was seeing it shoot out for the first time. 

Like I said though, I'm going to have it changed then keep monitoring everything after Monday. 

Thank you guys for all of your help!  I do appreciate it!

So...I had the HPFP replaced (just to be sure I caught whatever issues I was having).

I have the old gasket and the old HPFP and I'm wondering if there is a way to tell whether or not it was causeing a leak? 

The gasket didn't really look too bad. 

Also, the HPFP always seemed to tick consistently, and wasn't doing any of the non consistent ticking people were talking about when they go bad. 

Is there a way to tell (looking at my old HPFP) if it was leaking or not?

Why not post some pictures of the parts?  Maybe we can see something.
