Toxic old bastard
Any compressor wheel parts end up on the spark plugs?
I would assume not since there's still an oily intercooler in the way, but I guess finer particles could get through. We'll find out when I start taking things apart tonight.Any compressor wheel parts end up on the spark plugs?
You bringing either car to BG in May?A car woke up from its slumber and so will a dormant thread.

This resilient little B fired up on first crank as soon as I hooked up the battery. Never mind the vented tank 3/4 full of 5 month old E85. It didn't even hiccup the whole way home or to work this morning.

I think I need to find a new storage location though. All this corrosion is the last straw. Last year it was mice chewing up the GN's spark plug wires. Who knows what will happen next time. I'm not taking the risk.

To be fair, a lot of this will wipe off with a rag. It's just disappointing to see what a few months in a non-climate controlled space will do. We also discovered that the roof isn't exactly water tight anymore either, so it might as well have been outside. I really don't have the space to own and maintain two toys year-round. I have been looking for new properties with shops, but this really isn't the greatest time for the wife and I to pack up and move. We have a lot on our plates, and our current house is otherwise serving it's purpose. The cars will just have to share the garage without major repairs or upgrades for a while.
Now to address the elephant in the room. Why am I pulling my car from storage when there's still some snow on the ground?
It was never really about that. I just need a place off-site to park for the winter while I work on the other car. I'd rather store both of my cars in my heated two-car garage, but it doesn't work like that when I have to buzz in some floor pans or do a head swap! The Camaro is home so that it can donate its EV1 injectors to the GN. Besides, REAL spring is right around the corner! The Camaro will get the old EV6 injectors back since they work fine. After that I have a lot of plans for this car, but I think it's going to be a light year for updates while I replenish funds. The GN ate all my fun money!
Good to know. I sometimes fail to realize that the factory has yet to come up with a great simple solution for this. Last year the car was super stinky and smokey. I'm not sure what's changed since then, but it's been pretty clean this year. I just want to stay on top of it. I think I'm still confused as to what the "safe" method is though. It sounds like you have an open top catch can like mine, but do you have a PCV valve that draws any vacuum on the seals? No check valves? By "safe" are you referring to lack of KR induced by the oil fumes?I ran a myriad of PCV options with cans and valves before going back to a single open breather angled up from the rear (right) valve cover. I even have the components to build a Hobbs-tiggered evac pump, based on the Racetronix setup (relay-triggered Impala AIR injection pump under boost), which I still might throw in place just for extra draw even with the breather. I've also got Moroso exhaust evac components that I bought 6-7 years ago for it, inspired by my dad's 454 BBC mud truck system, but never went that route, either.
I smoked pretty good whenever I was trying various PCV pathways, and even when the fumes had to take a path to the can with an open breather on top. I went back to the safe method until I decide to put a vac/boost gauge on it, since I also did some over-drawing in 2021 when I turned the front seal into a chirping harmonica at ~2300rpm as I pulled air in past it, apparently.
Sure, having some draw would be nice to keep things cleaner, but with a turbo, the pathways require a good mapping out with check valves and such (even my EcoBoost truck attempts it, but I still had to add catch cans to help it out). It's way easier on 3800SC's and N/A's to dial it in, but my threshold for attention on the turbo car is low enough to go years between re-attemps at it.
I see. Yours is pretty similar mine then. I used to have just a breather filter but it was making a BIG mess.I've had the stock 3800 PCV valve plugged with RTV since Day1 of turbo'ing it, and blocked the draw path to the TB with N* adapter (both of which would see boosted air, of course). The 3800 valve might permit some light leaking in the center or outer edge, but doubt that's as much of a contribution to anything. Not sure of exact pathways for your UIM/LIM, but probably similar to other L36 routes.
By "safe," I mean I have just the open breather on an angled-up oil cap neck, so there's near-zero pressure in the +/- direction. It's better than going too hard either way, but not optimal, of course. It'll live forever, just could be better with lots of tinkering.
I've tried a fresh air draw from pre-turbo at the air filter, and venting via valve cover tubes to a breather can with check-valve to UIM vac port, but that never got happy, either.
As far as I know they're already blocked. The one that goes to the front of the throttle and the valve are plugged. I did want to check if the spring holding the valve into the LIM was maybe too weak? I see most of my issues when I let off the throttle from WOT or I'm engine braking. High crankcase pressure below and and high vacuum above could be pulling the PCV plug off its oring seat, but I think the spring is pretty strong.Honestly, you've probably never had the breather setup done quite right, from the sounds of it. If you haven't fully plugged both pathways before running the breather, your UIM air is still going places unexpectedly. When I start customizing air pathways, it's best to eliminate all OEM ones I'm about to circumvent, so they don't fight the new stuff. You should be able to eliminate smoke issues with a properly converted open breather setup, and if you want that still routed to a can with breather for safety, go for it.
Once you're in control of that situation, then it might be time to tinker with add-on items like an evac pump. Pretty sure my 14Apr reply mentioned the Racetronix-style stuff I've had in-hand for a bit, but am holding off as the car started behaving once I stopped trying to re-invent the wheel.
We had that same issue some 15 - 20 yrs ago... Always had to "test" every valve for proper operation.I bought an AC Delco PCV just to see how truly bad it is. I can blow right through the nipple with lung pressure which means boosting the crankcase will happen really quickly.
