Yea I'll likely be looking st the gen2 cover st some point as well. I'll just do that over the winter along with installation of a vented catch can. Have one now but not vented. For now just have the speedperformance vented oil cap for the gen1 valve cover.
Gotta get some of that stuff cleaned up in the offseason.

do NOT run that vented oil cap for the Gen1 valve cover at the track. With no baffle under the spout, oil (not just oil vapour) will come pouring out of the filter. The repeated WOT at the track will just saturate the cap filter and the oil will just drip down the side of the motor and over the engine bay.
I was down about half a litre of oil after a 15 minute session at TMP (the one and only time I ran the vented oil cap at the track...i was just lucky that the oil didn't catch fire on the exhaust manifold)... at 24 psi and oem oil cap, I had no issues with the dipstick lifting/popping or anything so I didn't really need the vented oil cap.
A vented catch can, sure ... a vented oil cap, even with the gen2 valve cover, is a no no at the track as you absolutely do not want any oil spray going onto the exhaust manifold.
Good to know. Yea, it's always been intended to be a temporary setup but looking like I need to boost the priority of the vented catch can setup. Looking like I'll just switch back to the stock oil cap then
(I'm only running stock boost right now, and even then, I'm not even boosting as I'm still waiting for a proper tune. Only thing is some MAF calibration in the short term.)
with the stock oil cap, at stock boost, even with a conservative 20 psi on that 2871, the worst that'll happen is oil in the intercooler piping.... and that's far better than an engine fire.
tbh, the vented oil cap wasn't an issue on the street. the fact that WOT logs on the street didn't show any signs of oil dripping out the vented cap lulled me into a false sense of security to run the vented oil cap at the track. however, it's the constant WOT on-off-on-off for minutes on end that'll lead to the issue.

Ok strange question anyone have suggestions on how best to remove the symtech coating from under the engine bay?
Car is not a daily and sits in the garage. Won't see any more winters. It's a track car now so not looking to make it show room but the 10 year old symtech just looks like caked on grease and dirt, so I'd like to make it a bit more presentable.

The speed section is a ghost town. Who is tracking their speed?
Oh damn, that sucks. Oh well, I stopped reading the Speed section because according to certain people only speed owners are allowed to even look at that section.

I expect the car will make somewhere in the 340-360ish whp range, but I'll know after tonight. For track, I plan to bring that back down closer to 300-320 whp.
No track experience. Autocross runs + autocross school, and 3 years of sim racing experience on iRacing (lolz amirite?). Hence the track school in October
PS: you own a Speed now, so you can look at the Speed forums again (I know what car you bought! )

Does anyone here have an extra BPV laying around? I have a feeling my Forge V2 BPV may be the thing causing my boost leak.
It would be a huge help as it would save me from buying one just to test my theory out.

Then you pick from the scroll down to - FMDVMAZ3S
I put the two shims in (already have the red spring installed) it seems to hold better but still leaks. When I inspected the piston it is pretty scored on the sides.
