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?
