smoke show


Recommended Posts

well that ran great for about 2 weeks

 

all I can do is laugh... rolling home on cruise I was coming down an incline and -woooof - massive cloud of oil smoke out the exhaust :banana:

 

disengaged cruise and rolled into my car port on the edge of town at an idle

 

oil pressure is up where it belongs, no noises under the hood, but something just let go and it's smoky-the-pig

 

maybe I can get my other block back from the junkyard, all it needed was a water pump, idler bearing, belts and an oil pump re-seal :grin:

after it, and I, cool down - I'll nose around and see what there is to see - it was still running great - it was almost like some kind of seal cut loose but the PSI was up where it has been...

 

hmm

if you were going downhill in gear, it may just be some crap that blew out of one of the valves. Got a compression tester?

 

yeah I'm going to pull the plugs and check the compression while I'm checking it all out

 

it was a pretty serious cloud* (like the way it hangs in the vacuum behind the car) and it was smoking at an idle when I pulled in, a little blip on the throttle made pretty blue clouds in the breeze

 

*it looked like the time I blew the oil seals on a Mazda rotary, or more recently, when a turbo fails

weird

 

the oil and coolant are clean and full

 

there is no evidence of any oil going down the throttle body from the PCV - still nice and clean

 

the compression surprised me, it's an (ab)used engine, I was expecting a lot worse

 

#1 170 psi

#3 166 "

#2 158 "

#4 162 "

 

just barely under 10% from worst to best - certainly nothing that would indicate a ring or valve problem

 

hmmm, valve stem seals or Baccaruda's random bit of crud theory...

 

B's idea has some merit, the original air cleaner was clogged really badly when I pulled the engine, and the pcv had to have been getting really pulled on hard to try and make up for it... there was a lot of crap in the pcv - I thought I'd wait and see how it ran before I got too excited, give it a chance to burn some junk out

 

hmmmpph I'll drive it a bit and see what happens

All the PCV hoses still connected?

Had something like this happen to me when I crossed some hoses on a carbed EA82. My wife was behind me and she thought I was on fire.

 

:lol: you're killing me :lol:

 

Good point, I'll double check the hose routing against the manual just to be sure I didn't overlook something weird from the engine's PO _ I rinsed all the tubing with solvent to clean it out, but that doesn't mean it was connected right to begin with

it cleared up on it's own, file this one under 'WTF was that all about' :rolleyes:

 

Baccaruda's random crud theory vindicated? :)

 

I have had a lot of engines over the years, I've never seen one lay down a smoke screen like that and then get magically all better by themselves... I mean that was one sick cloud that burped out all at once -for no apparent reason.

 

I'm hoping this isn't one of those things that will show itself when something horribly breaks... you know, one of those after the fact 'gee I guess that explains why' deals :eek:

my old 90 loyale that I sold to my neighbor ( I only had it for a short time and all night driving so i never seen it ) well anyways he works at boeing and when he takes this certain right curve on the way to work (freeway offramp) the car smokes like a old steam freight train once in a while NOT ALLWAYS.

 

So I did some lookin on this site a I found some imfo that some ea82's smoke going around long curves right or left I cant remember.

 

I also found out subaru redid the PVC system to stop that smoke.

But I could be wrong.

 

So apparently it happens once In a while

that would be wild! it was a long downhill right hand bend too...

 

now, we have a severe grade nearby, (The Lewiston Idaho grade) THAT I can see, if you roll down that in 5th you'll be under compression for a good 10 minutes to get to the bottom

 

even a good, reasonably tight engine will let out some smoke when you get back on the gas at the bottom - you've been loading up all the way down

 

this was kind of weird, the cruise was on, but it wasn't on the throttle because of the hill - it was coasting

 

I dunno, maybe there was just a lot more cleaning up to do than I thought... :rolleyes:

  • 2 weeks later...

DID it again! Same corner, downhill to the right with the cruise control on, rolling under compression - hit the exit of the corner and watched the smoke absolutely ROLL in my airstream :eek:

 

damn that's cool :rolleyes:
