Oil pooled on intake valve??? Related to Recall? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

kt45 · 03-25-2019, 02:58 PM

Background:
So one day after I got off work, I heard a rattle sound when I started up my 2013 BRZ with 76000 miles, no boost, which also happens to be one of the affected VINs for the J02 recall. The rattle went away a few seconds later so I thought nothing of it. When I clutched in and braked for a stop light my car stalled out. I managed to get it started but heard the rattle again. Tried to make it home which was 5 miles away but broke down 3 miles later. Couldn't get it started and had it towed (2 miles and a cop bumped me about 1/4 mile to a nearby parking lot smh)

Got only one code from my code reader: P050A (Cold Start performance/IACV issue). Tried starting it at my house but couldn't get it to idle. The rattle I heard before seemed to be coming from the passenger side of the motor. Throttle seems to be working as it completely opens with accelerator pressed in. Pulling off my throttle body I noticed there is a good amount of oil in the intake manifold. After taking off my manifold I noticed that all of the valves were somewhat dirty but a valve on the passenger side had oil pooling in it.

Now I'm hesitant to take it to the dealer from hearing all of the issues going on with the recall work, plus I'll have to get it towed there just for a diagnosis and would rather do it myself. Do you guys think this is a valve spring issue?

No, this isn't related to potentially faulty valve springs. Seems more like bad valve seals or serious blowby. Are you burning oil? I rebuilt my engine at 93K miles and my valves were prestine clean. Something is definitely not right there.

I'm guessing valve seals too. Had these go on my 3000GT VR4 and I was basically James Bond with a smoke screen. I can't explain the stalling, aside your car breathing more oil than air and your plugs being saturated.

I want to second the oil burning question; do you notice a lot of smoke after idling and then stepping on the gas to start driving?

kt45 · 03-25-2019, 04:01 PM

Nope no burning oil smell or smoke. I do have a small leak around one of my cam covers on the other side. I was thinking maybe the PCV valve is sticking or something. There's oil on the throttle body as well. Also when I pulled my exhaust off I found that the cat in my JDL UEL headers had completely disintegrated leaving a pile of cat pieces on my cat in my front pipe.

I wouldn't be so quick to dismiss a valve spring issue. A week or broken spring could have the same symptoms.

Along with other symptoms that would be hard to miss. Also he is showing multiple wet valves. This valve spring issue is so rare I doubt he is the one unlucky person with not just one but at least two bad valves.

Are you running a tune that has you extremely rich? That would be hell on your cats. Have you checked your AFR lately?

Symptoms such as rattles, stalling and failure to restart? Not saying it is the issue just that it can't be ruled out yet.
Doesn't explain all the oil everywhere though.

He said he just had the valve recall done.... Any way that the work can screw up the valve seals?

So, you had the recall work done?

If so, I'd suggest you take it back to that dealer.

They can't mess it up any more than it looks to be messed up already.

Sorry for the confusion. But no, I have not had the recall work done.

I was running the oft stage 2 v4.03 tune. I havent really been logging but my afr when I looked at it was 14ish:1. I did notice a dip down to 12 I believe when I'd let off the throttle.

Well the other 2 valves look like the right valve in the picture.
