Anyone have blue smoke come out of the exhuats when they start thier 2.8? I pretty sure i know what it is, but am 50/50 weather or not i should get it fixed. Mine does it alot sometime and never sometimes, so idk. Thanks guys

 

does it happen only when you start, or is it like the dodge "blue smoke of death" always pumping thru the tail pipes?

Just on sart up is valve stem seals usually.

 

more detail

hey i worked for dodge!!!! yea theyre known for that, but mostly the 3.0 liter. valve guides were kinda a POS.

 

Only on startup, sometimes never, sometimes a lil, and sometimes alot, only on startup. I was told vavle seals or guides, and eays solutions? I run 10w-30 with Marvel mystry oil. Thanks guys

 

the only thing that will cause that is valve guide seals or piston rings.

 

how worried should i be, and is it fine to drive the car like this? Thanks again

 

in the long run, its not good. but unless you have the cash to tear it down, youre gonna have to drive it that way. the best way to tell is do a compression test. if your PSI results are low, squirt a lil bit of oil and do it again, if they are higher, its the rings, if they stay the same, its the guide seals. just a lil bit from an oil can will be enough though.

 

Mine bellows out blue smoke during cold starts, and when I rev it high.

 

I've had that since 1996, when I totalled my car, and it sat for a month without starting. I think they dried up, and then got cracks in 'em (like all rubber eventually does).

It's no big deal... you might get some extra oily buildup in the exhaust pipes, but I wouldn't go tearing apart the motor just to replace them! (Actually, I haven't replaced them yet on my motor... it's been, what, 8 years? )

 

Nothing wrong with a little extra upper cylinder lube in an old chevy

 

Thanks guys. Yeah I don't have the cash so I will just leave it be, it doesn't hurt anything right? plugs? or cat? Hope not, LOL Thanks again

 

You might have to clean or replace your plugs a little more often than usual.. new plugs every 3-6 months or the joy of tearing down your top end... bit of a toss-up. After a while messing with the plugs you'll probably even figure out which cylinders are leaking and which aren't. I'd be surprised if my #1 cylinder even fires, personally.

 

Tech... why wouldn't it fire? It puffs a lil on start up, do any of those oil leak stopper **** work? You mix it with your oil?

 

They only work to a point.. my #1 plug comes out oil fouled regardless of the snake oils I've put in the motor.

 

Tech- how many miles you have on your 2.8?

TomP, what have you done to your 2.8 and how many miles? How much horse do youo have?

Thanks guys

 

~165k miles... and she was burning oil long before the turbo, so that's not a factor (thought I'd point that out in case it were asked later).

 

Turbo? What have you done to your 2.8?

 

Far too much, and definitely not enough.

The list of things I need is far more impressive than the list of what I have (hair dryer excluded)... injectors, ecu, chip, 2 bar map sensor, 3.1 or 3.4 shortblock, spare time to port spare heads, intake port work, custom plenum fabrication, transmission work, probably a new clutch (Guess what, guys? Looks like I glazed my clutch in 500 miles! Go turbo!! I feel for ya now, Doward )

It's a project beater for now.

 

Thats awesome, how much $ you put in it if you don't mind me asking? You notice big improvement? I have a 2.8 and i have about 300$ right now that I want to put toward the motor, any ideas what would give me the best performance with that money? Thanks once again, i'm learning alot

 

Performance-wise... ~650 in the T5 swap, ~100 in the turbo setup.... ~75 in the 16" IROC wheels I can't afford to put rubber on yet... that previous list was a very incomplete list of the things I need, not what I have.

Err.. to answer your question.. my opinion on $$ spendatures is not something you want to delve into unless you really don't care about your car. My V6 no longer holds value to me, so I don't mind breaking it (in fact I rather expect to) and I cut corners like no other... not that I want to, I've just learned how to do things on a nonexistant budget.

 

Thats cool, I just want to sqeeze more power out of my 2.8, i'd like 160 or something. Thanks man

 

i dont have a v-6 but yeah mine smokes on startup too. usually if i dont start the engine till the fuel pump is done priming or whatever it does when power first comes to it, then it doesn't smoke. if i crank it right up it will always smoke though.

i was told it's nothing to worry about really, just check your oil more often than normal. the only thing is it's kinda embarresing having a nice looking car, and cranking it up with 10 people in the parking lot near you, seeing the smoke cloud come up. even if a car's fast and looks good, people still think it's a POS if they see it smoke on startup. but burning on startup is way less crappy then burning it continuosly driving down the road

 

Yeah exactly, I here ya there. I have a nice car, but seeing that blue smoke kills me. People are like whats wrong with it. Thats the only thing that bothers me

 

Nothing's wrong with it! It's your "stock upper cylinder lubrication system option".

 

What about that turbo. Did you manage to make one or something?

 

No.. I was given one that I traded off for another one that I sold to get money to buy the one I'm using.... Total cost: freebie!!

 

I would like a Turbo in my 2.8, she needs a bit more power. Can valve seals get any worse over time or do they pretty much stay the same? Thanks again guys

 

They can get worse.

 

how i figure it is that it is a very minor problem, and the motor will do FINE for at least 6 more years without fixing anything. 6 years from now i definetely plan to have done a complete rebuild with better parts, or just gotten a new engine entirely. if it craps out some time before 6 years (which if it does, it won't have anything to do with the valve seals), then it'll just push me to start building up the engine a little early
