Smoking

I've got white smoke coming out of my catchcan and the sides of my VCs. My CC isn't rerouted into the intake and it's not pulling vacuum (I know that's wrong, trying to track down a stock accordion hose to fix), but the smoking is new. It started doing it after four or five 0-120 pulls and does it every time I run the car now. Thoughts?

is it bad smoking? i had breathers on my valve covers for a while and they always smoked.

be sure to filter it - or have some sort of suction if each line from the cc is connected to the valve covers that is bad news the crank vent has to go soewhere

even on my 2j im working it to do that welding fittings on my intake pipe

I have an open hole on the CC and the vacuum nipple on top, both of my VCs vent into the same line and then go to CC. It's pretty bad, it's not blinding or anything but you can easily tell it's happening, and the CC smoke is visible with the hood shut. The smoke wasn't happening at all before those back to back pulls. I just re-did my front cam caps and VCs, but I did it according to TSRM, and it was smoking before. I'm guessing the smoke was just directed out the top as it had no where else to go (originally had RTV sealing my VCs down). I emptied my CC, it was at least half full of this mud colored crap. I can't think of anything else that would affect it. I'm going to grab a stock accordion hose so I can pull vacuum, but it'll still be smoking.

No milk and coolant level was good. No knocks, pings, ticks or any weird noises other than my belts because they have coolant on them. The mud colored stuff came out of my catch can.

Might want to do a compression test to see if you got blow by on the rings or cooked a valve.

Yep, bad rings. I have the same problem, number 3 cylinder is sucking oil past the rings on decel so after about a week I have about 1" of moisture and brown sludge.

Update: Interesting sound on start up, sounds like a belt possibly? Not really sure, might be related. Doesn't sound metallic.

On first start up, a lot more smoke than usual out the exhaust (condensation maybe? it's decently cold outside), no noticed smoke from valve covers. I shut down, checked all fluid levels (good to go) and

Fire up number two: No noticed smoke, same weird sound. Will do a compression test when I figure out what the weird sound is (my car takes an extraordinarily long time to warm up, don't want to risk screwing something else up)

Update two: Started it up again, still making that weird noise, coolant is ending up on my fan somehow and spraying around. Yet again, no smoke

Check the upper rad. hose, t.stat. housing(seen a few with only one bolt), etc. You really need to pressure test the cooling system and find the leak.

Check the tension of the belts. They should flex a little(1/4" or so). If you can wiggle them easily, tighten them up. Might also check the idler pulley for the a/c.


Smoke when its cold outside is, usually, normal condensation The ambient outside temperature just makes it easier to see. It's always there, however ;)
If it fogs out a couple of the surrounding houses, though, you might worry a bit...

For your unusually long warm up issue, you might check the t.stat and make sure it's not stuck open.

That's one hilarious avatar, btw.

Thanks. I'm thinking I just didn't get the tstat housing tightened down on the bottom bolt. It's either that or the upper rad house where it meets the tstat housing. It usually smokes a little on startup but this was a lot, and it was coming from my catchcan. Nfi, it went away without me messing with anything lol

Could have just been condensation and a cold, dry day. Check the neck where the upper rad. hose attaches to the t.stat housing. If there is a bunch of white corrosion on there, it can cause the hose not to seal properly. Be careful tightening those little t.stat housing bolts, they're easy to break.

I failed at something, metal noise coming from directly under my VC. Either my cam is grinding on my cam cap or I have an epically failed valve. In the process of pulling my cam caps off now to take a gander, I'll post some pics up if it looks damaged at all.

Yes no maybe? Rest of cam and all the caps looked fine. I made sure all the caps were secure and had a little oil on the cams and in between the cams and the caps.

I figured out what the screeching was. Apparently I forgot to tighten one of the bolts that holds the timing plate down all the way, and the screeching was the cam gear grinding it. It bent it over and deformed/stripped the hole. When I put my hand on the cover, it quieted down a lot. I couldn't find the original so I grabbed a spare out of my spare head and installed it. After running the motor for a second (sound was still there) the edges of the bolt were shiny and the bolt was very hot. That was as far in as it could go. I don't really know what to do now, is there a way I could fill and tap the hole or something?

How bad is the hole? If all the threads are pulled out, you could drill and tap it to the next size up, and use a new bolt.

That's a good idea, too. Just make sure you install it(helicoil) correctly, and locktite it. Nothing worse than trying to remove a bolt, and the helicoil tries to come with it.

After idling for maybe a minute since I dumped it last, my CC already had some fluid in it, smells very strongly like oil. Just thought I'd add that.
