Evac system works a little too good!

I was driving home yesterday - with my leaky fitting that I had slather with red gagunga juice - and this old couple in front of me had gotten on my last nerve. So popped into 2nd, gunned it, and boosted on by them. Only to look in my rearview and see a huge plume of smoke shooting from the ass end of my car.

Oh fuck. This is ain't good.

Oil pressure and temps are good. Coolant is good, car is running fine, so I ease the last mile home and park the car to let it cool. I'm thinking I blocked my return line with too much RTV and blew the seals on the turbo.

She finally cools down and I start ripping things apart, fearing for the worst. Plugs are nice and brown and so are the tops of the pistons. Check, no blown ring. Pull off the exhaust and the DP. Check, no oil in the discharge side. Pull off the intake tube and bottom charge pipe. Check no oil there either.

Problem found. Evac system works TOO well. Under boost, the intake mani valve shuts and all crankcase gases are evac'd into the exhaust, before the cat. Since this is pretty much uncombusted vapor, it makes a huge super Batmobile cloud of smoke as it gets dumped into the superheated exhaust stream.

= big fucking cloud of smoke.

Need less to say, I pulled the evac line out of my exhaust feed, stuck a filter on it and plugged the line going into the exhaust. I'll cut it off and weld it closed later.

glad to hear you found and fixed the issue!!

Now on to the oil fitting debacle.

Motherfucker is still leaking although not nearly as much as it was before. This is still too much for my taste. So I get to thinking.

This country sucks if you want to find anything that isn't a factory part and getting work done is ridiculously expensive. This rules out buying an aluminum -10 AN bung and getting it TIG'd onto my old pan. Yes I can order stuff from the states, but that's a long time to be leaking oil. Plus the Rubi is gone so I can't deadline the Civic and steal Momma's truck.

Hmm. I converted the return on the turbo to take a standard nipple instead of an AN compression fitting.......that means I still have that 1/2" NPT to -10AN 45 degree fitting that came with my oil feed kit.......and I've got this virgin aluminum pan........and I've got a 1/2" step drill bit.......and a shit ton of JB Weld.......

Yep. My mom drowned all the stupid kids.


Shablam!!





Squeegle squeegle





Glorp!





Sceeerrrtttchch! (fitting was tight! probably didn't need the JB Weld, but it's insurance)




Fwivvvvvah!




Blerrrring!





So you can see that there is no chance for oil to leak out of the union between fitting and pan. It's threaded tightly, JB welded, and the geometry of the fitting end and the exit into the pan is such that it won't leak from there. I have the fitting I used to run on this (prior to converting to a nipple) and they never leaked.

So I think I'm good. I just have to wait for some hose to get here and I should be leak free once more.

Now I just have diagnose a new, strange whistle when I shut the car down that I have never heard before. Sounds like a boost leak, but I have zero signs and symptoms of one. Always an adventure.....

lol debacle lol

Damn Clint! I just ordered all of my parts for the evac setup!!!! DAMNIT!!!!!!!!!!!!!!!!!!!!!!!!!!
I guess we can just run the intake manifold side w/ check valves?

The whistle noise is very common especially with a cold air intake / have your wife shut it off & put you're ear to the turbo intake filter. I bet it whistles

Man, now what are we gonna do for evac?

[speedfoos]

Naw, this is a new whistle. It never used to do this. I'll take a little vid of it tomorrow morning and post it up. It does it when the intake tube is off the turbo as well. Weirdest thing.

I'm not sure what do to for the evac, I mean it's fine for the car to dump all that smoke out, but I think the tree huggers will end up slashing my ties and stuffing potatoes into my exhaust - although they'd have to be big ones because of the 3" tubing!

I mean, it's fine at this point with just a filter on the end and boost pressure pushing out it during boost (IM check valve closed) and the then it gets re-circed into intake charge during vac driving (former exhaust check valve closed). I would still run it the same, you now don't have to cut into the exhaust.

Debacle is one of my favorite words Don.

Well, i'm glad to hear that its coming along clint! gl with the rest of them!

[sl33pyriceboi]

wow? jb weld? i knew that shi t was strong.....but i didnt know it was THAT strong....

so it never leaked on u speedfoos?

[greeen01civic4d]

ill bet ur whistle is in the exhaust somewhere, not to question ur skills, but i bet u have a pinhole leak somewhere that is creating a whistle.... its prolly ur only new addition to the car lately, id check there first, with a giant swap and some soap

[Alpha 5]

YOu could let your car suck up some of the seafoam crap.....It causes it to smoke like a big dog. I promise if there is a leak in your exhaust you will find it with this stuff....

[dopes6070]

Hey alpha thats an awesome idea HAHA. I say go for that!

[Alpha 5]

Thanks.....I just hope they have that stuff in the UK.

[speedfoos]

Nope, no thanks on the Seafoam. I was thinking exhaust too Adam, but it's coming from the front of the car, and I didn't mess with anything before the cat.

The JB Weld is just insurance. That fitting threaded in really tight so I'm not worried about it leaking or moving at all even without the JB Weld.

[WilmncChris]

Just my two cents, but if that was my setup I would braze the fitting onto the pan.

[filipinop1405]

I'm stupid but what does braze mean chris
