could this be my problem?

[mcammarn]

so after reading other post about pcv issues, i think i want to say this could be the reasoning why my car does what it does.
yes i put the tape over. i figured i didnt need the open hole there, so i covered it. im guessing thats why my car may be smoking out the exhaust?
or yes it could be valve stem seals, or piston rings. i looked before and after the turbo, and found no oil in the pipes.so i dont think its turbo.
if so, what can i do for that open hole in the accordian?

Oh wow,.... Um You may want to find a more permanent solution to sealing that connection. The adhesive properties of, what I assume is electrical tape, will not hold up to under hood temps for very long. And if it fails it will allow a large amount of un-metered air into the system, since it is after the air flow meter. If this were to happen under boost, the motor will run extremely lean, and almost certainly grenade. So a more permanent and reliable solution should be found ASAP. You can get rubber caps, like the one that goes on the water line hard pipes, from Toyota, and then use a clamp. And just a heads up, you might want to don a flame suit, as many guys will come down hard on a mod like that.

Next, a little more info would be helpful in diagnosing your problem.
What color smoke is it?
When does it smoke?
Is this a recent development, and what has been changed or modified since it started happening?

You mention the PCV system, have you modified anything on it?

Ok for one that is the port for the stock recirc valve (bov) ...

Find a cork on some sort problem solved. If it helps the metal tube does pull out the accordian pipe..

Fix it ASAP.

But I personally don't think this is all of your issue

Oh my god

 

[mcammarn]

smoke is whitish. happens on cold start,hard excelleration, and neutral.
i havnt messed with my pcv system. just in other searches, in topic to smoking, people were mentioning pcv hoses not be connected. either to accordian or elsewhere.

White is coolant. Start looking for signs of a BHG.

[jake8790]

Go to an auto parts store and ask for a 3/4" bypass cap.

I'm guessing your HG is blown if you drove with that hole open.

 

[Dirgle]

It might be a little early for a BHG diagnosis, it's one of still many potential reasons for the smoke. It has a high potential considering the situation, but we still need to look in to it more.

Like Another MKIII said white is coolant. White with a blue tint to it is oil. Sometimes it is easy to confuse the two without a point of reference. Do you know which one for sure? You can get out and smell it. Coolant will be sweet, and oil will smell like, well, oil.

 

[mcammarn]

wel can def. smell oil coming out the exhaust.

 

[jonahs_supra]

i wouldnt run my car with tape covering a hole
under heat the glue breaks down to almost a liquid form
very possible you could find the tape has came off and your turbo has tape caught in compressor wheel lol(more then likely damaging wheel)

with the hole being open your car is now using unmetered air
with that being said your afm has already sent a signal to the ecu for xx amount of air for xx amount of fuel etc...now your adding another xx amount of air that ecu doesnt know about
causing engine to run lean


just like others stated white is normally a BIG indication to BHG
i would start watching your coolant level closesly
pull and inspect plugs for fouling and wetness
when exhaust does smoke white smell the exhaust...if its got a sweet smell then more then likely its cause of a BHG

also dont put mouth over exhaust tail pipe trying to taste exhaust fumes :biglaugh:

Ok, moving forward with the belief that the smoke is oil, it can enter the combustion at four points. PCV, turbo, valve seals, and head gasket.

Considering the times you mention it is smoking it could be any of the four. It's not often the valve stem seals go bad on the 7m, so well look at that last. First I would check under your oil cap for a build up that looks like milkshake. This is a simple, quick indicator that we may be looking at a BHG. If that is ok move on to you lower intercooler pipe, pull it off and see if any oil comes out. If if does it could be the turbo, or the PCV system. Next pull off the accordian hose off the turbo and check for shaft play. If you have a lot your turbo is on its way out. If you have access to the tools you could do a compression check. Low numbers point to piston rings, which can push oil throuh the PCV system or a possible BHG.

Check these things and get back to us.

 

[mcammarn]

as of right now currently. im taking the head off. i dont think the head gasket has ever been done. it has 127xxx miles. the coolant level is good. well not no more since i took it all out.lol. but i did take the accordian pipe off and did see a tiny bit of oil on the lip of the turbo. tiny bit meaning like a eye drop. ill check for shaft play tommorrow.

 

[Turbo Habanero]

Oil on turbo is normal its from the PCV system well maybe not normal but common

Sounds good bud. Take your time and do it right. If you have questions don't hesitate to ask. Like mentioned, a small amount of oil on the turbo is normal for these cars, due to the PCV return.

And welcome to the HG replacement club, our spirits are high, and our numbers are many.

heres the smoke.
did a compression test, cylinder1-160 cylinder 2-5, 145 cylinder 6-150
is it safe to say its not a bhg? and that its the valve stem seals or maybe valve guides?

 

[AJ'S 88NA]

Looks to be a little more than valve guides, is that at just an idle?

 

[Supracentral]

I'd suspect turbo seals or a cracked CHRA with that volume of smoke...

 

[mcammarn]

smoke only appears on cold start. and it appears on hard acceleratin. like if im racing someone. then at idle, it will smke for alittle bit till i drive off.

this is at idle.

I'd suspect turbo seals or a cracked CHRA with that volume of smoke...

i looked before and after turbo for oil and found none.and not sure what chra is.

 

[Supracentral]

not sure what chra is.

Sorry, it's turbo jargon = center housing rotating assembly

It's the part of the turbo that isn't the compressor or the turbine:

 

[harley1985]

hmmm suspect. thats awefully white smoke. did you do a cylinder leak down test? check it out
