I have a 00 civic si and its been boosted for about 800 - 1000 miles...the engine has 56k on it.....ok, so i didnt drive the car yesterday and today when i turned it on it was smoking blue everywhere....alot of smoke....the thing is on dp so i looked under there and it was just puffing out blue smoke.....i guess im burning oil but after i started driving it went away....when i get on it hard ill see a little smoke come inside the car...i have an oil leak which is right on top of the dp so i thought it was oil dripping on the dp when hot but when i got under there to look today i noticed it was puffing blue smoke.....yes i know i know, rings or valve seals but why will it go away? the turbo kit was brand new btw........

slowsol95

its more than likely the vave seals because when it sits for a while it gives the oil in the head time to leak past the seals. this is where bad seals start out. in my last motor, my valve seals started out like this and before long it burned oil when driving also.

Nordy

that makes sense.....so will it hurt anything if i keep driving like this? how hard of a fix and how expensive is it?

jdm91integ

^^^^ Yeah sounds like valve seals to me aswell.

Nordy

if it was leaking seals wouldnt it loose oil? I check the oil almost every other day and i dont really see it loosing oil.....

slowsol95

it doesn't mean that you are losing enough to see it in a week or so. it only takes a few drops of oil to leak past your seals to be able to see blue smoke.

Nordy

gotcha but i was seeing alot of smoke...like damn!

alpha

Too much VTEC in your oil Norlandt

I compression tested his car a couple minutes ago to put his mind at ease. I will let him post the results. Turned the injectors and coil off. Wide open throttle. 8 cranks

Nordy

compression test results were....220, 210, 220, 215

Nordy

ok so i had the valve seals replaced by a well known mechanic and it still doing it.....i guess if its not the valve seals then it is the piston rings? Thing is, right after the head was put on i was there when they fired it up..it didnt smoke at all but when it sat over night it smoked this morning...which still sounds like valve seals to me wtf.....damn.....

did you ask to see the old valve seals?

xsi-t

Maybe it's that magic oil the previous owner put in doing it's job -Alpha

Nordy

lol...i hope the magic isn't wearing off so suddenly....and no i forgot to ask to see the valves since he is a trusted mechanic....

agrn93ls

possible seep in turbo seal then on exh side??

Nordy

i called the mechanic up and he said he couldn't visibly notice anything wrong with the valve seals but then again u cant see anything unless they're really screwed heh.....so we were talking and i mentioned that i dont have a restrictor on my feed line but it is a -3 line and i know people who dont run them and are fine.....he said to try one and if not he thinks it is the rings...while driving i sometimes smell the same burnt oil smell that i get in the mornings when the smoke starts....after pushing it hard sometimes i get a little bit of smoke rise into the cabin with the same smell since the downpipe is right in between both front seats....hope its not the rings but its looking more and more like it.....

Nordy

popped the hood after running it and i saw smoke coming out of the valve cover breather filter and endyn catch can filter...i dont think there's much more to talk about.....i have searched and in all cases the piston rings are shot.....******* piece of ******* ****...oh well, time to build!

Nordy

just did a compression test....225 all across the board.....i did it on an old compression tester about a month ago and it came out to 220, 210, 220, 215 ...... this is a brand new compression tester and it came out to this....this was with the distributor disconnected, throttle wide open, and 8 cranks....

alpha

Like I said. Leakdown test is next. If that turns up nothing than turn up the boost

xsi-t

Yo nordy the white smoke from the can is vapor. both icc and me get the same white smoke, oh and ive seen shawns car do it also. you need to buy a leakdown test and go from there.. stop beating your head on the wall and buy the tester.

building boost

time for a leakdown test.

Nordy

you guys are right..if the leakdown tester is not too crazy expensive ill buy it and we'll do it saturday or something at brother's shop....that way we have a leakdown tester in the fam we all could use in situations like this to relieve stress....or.....to multiply it lol thanx guys lets see what happens....

Nordy

leakdown test results:

cylinder 1: 4%
cylinder 2: 6%
cylinder 3: 5%
cylinder 4: 7%

so i guess the motor is good.......hmm...........

Only thing I could think of, assuming its not the block/head, is that you need to further restrict the oil to the turbo. -3an is .125" ID, and many people run .050" or smaller restrictors and don't have chra oil starving/overheating(oil-cooled only) issues. It could be that when you shut if off, the chra is filled enough with oil (due to overfilling/under draining) to weep out a tiny bit into the housings before the level drops enough.

Otherwise theres the outside chance its a valve doing this. It could get scratched just enough in a worst-case scenerio to leak oil by even new seals.

Only test I can suggest is to leave it sit for the usual period, pull the spark plug wire and injector clip from cyl 1, start it up, observe exhaust color, turn off, plug them back in, restart it up & observe. Repeat the next 3 days to check all 4 cylinders. You can at least determine what cylinders are causing it.

Nordy

i think i will try a restrictor next.....wouldnt hurt....heh
