What' sup guys i have a 95 impala ss and was wondering why would smoke be coming from the dipstick tube? Dye was recently added to find an intake leak that i had would that have anything to do with it? Thanks

Either the PCV/vent hoses are clogged, or you have excessive blow-by.

Hopefully the former. If its a lot of smoke, start shopping for a motor.

Mine (L05) went downhill quick after I noticed it. What was a noticable amount of smoke six months ago now pressurizes the crankcase and blows the PCV valve out of the grommet or the dipstick out of the tube, or both.

I'm currently in the middle of swapping it out.

no not excessive at all, i just noticed that it was doing it a little when i checked the engine. I just got a new PVC valve put in recently, and how do i stop it any questions. And i pray that it is not that i need another engine. I only have 110,000 on this one, How do i unclogg the PCV vent hoses, thanks

 

[LT1allday]

how do i stop the blow by?

Either the PCV/vent hoses are clogged, or you have excessive blow-by.

+1, maybe the shops blunder involves the pcv hose? You could try 1 grade thicker oil, but thats a band-aid for excessive blow-by, since its caused by bad rings. You could also check to see that the pcv has vacuum.

 

[LT1allday]

so really are you saying that i am looking at a blown motor? Or one that is about to blow

 

[LT1allday]

car runs fine, please don't tell me it's time for a rebuild that would be some BS.

 

[DiGGM95]

Not saying that its that bad, before theorizing further, you should pull the pcv valve and verify it has good vacuum. If not, the rubber pcv fitting could be cracked, or the metal pcv tube going to the front of the intake plugged/pinched.

 

[LT1allday]

oh ok thanks alot finially some hope, i'll check the PVC hose or replace it and the fitting on the front of the intake and or replace it and hopefully that helps. Fingers crossed

 

[LT1allday]

by the way the PVC valve is brand new from the dealership installed a couple of days ago, but how do you check to see if it has good vaccume? Thanks

 

[DiGGM95]

Id just pull the metal tube loose from the pcv valve rubber hose looking-piece that attaches the pcv to the metal tube. The metal tube is annoying and i find it easier to do it this way. There should be decent vacuum with the engine idling. Also, once the metal tube is disconnected, the pcv is easier to remove.

 

[LT1allday]

the engine should continue to idle am i correct, with the hose disconnected. And you don't mean the actual metal connector on the PCV valve do you?

 

[LT1allday]

and if it is a decent vaacum coming from the PCV valve, then am i looking atleast into getting new rings or a rebuild, god i hope not

 

[DiGGM95]

It should idle, abeit a little higher. Basicaly like a huge vacuum leak if theres decent vacuum. I don't know of another place to check for vacuum to the pcv other than the other rubber piece on the other end of the metal tube thats kinda under the TB.

 

[LT1allday]

cool thanks alot man, ya i'll look into it tomarrow, and maybe replace the tubing to see if that helps.

 

[LT1allday]

I'm getting good suction from the pcv hose, i put my finger in it and it after i disconnected the metal part. what next to look for?

 

[DiGGM95]

Does it use any oil? If it does, id go ahead and run a compression test across all cylnders to see how the rings are.

 

[LT1allday]

not really i've had a intake leak recently so i really have not had a chance to see if it uses oil, but i'll keep a check on it.

 

[DiGGM95]

Id just keep an eye on the oil psi and oil level if the car runs ok, with no knocks, blue exhaust smoke or oil consumption. EDIT: About the the oil psi, have you done the 9c1 oil pressure sender mod or HuSSkers better than 9c1 oil pressure sender mod? if not, the factory 95 SS oil gauge will not read true...
