blue smoke....

[bluegtp]

I don't know who read my post about loss of rpm before, but now I have a bigger problem (possibly related?). Today I was driving along, just left a stop light and looked in my mirror in time to see a pile of blue smoke poor out my exhaust. I made it to the next place I could pull over (didn't want to drive) and by the time I got there I noticed a minor loss in power. What are the possibilities for this? My mechanic thinks headgasket. All the fluids looked fine, they were all up to the right level, antifreeze is the right color, and the oil is still nice and clean.

Blue smoke is Burning oil.
White smoke is head.

or is it the other way around?

Yup.

New oil tends to burn blueish, the older the oil it tends to burn easier and turn black even sooty.

Take a sniff of the exhaust (don't get carried away!!) if oil is buring up the exhaust would have a different smell, well like burning oil

apparently I have a blown intake gasket. My mechanic says this should be the cause of the blue smoke and the misfire code I was getting on cylinders 2 and 3.

Theres no oil going through the intake gaskets on the dohc. Tell your mechanic to try again.

better yet, go to a mechanic that knows what hes doing

[Juglenaut]

Head gasket, piston rings, valves seal/guides can cause burning of the oil.

I was pondering this I believe that Blue smoke mean that the oil is not burned completly and may be entering the Cat from the exhaust valve seals or you are just getting to much blow-by..

Replace all your PCV's.

If you ahev recently(last 200 miles) gotten any new piping on your exahust or done any header setup(it could be doen ya know) then that could be it. My car smoked for about 180miles as it burned out the grease/oil that was used to bend the pipe and make it.

Also if it was not stainless piping, I bet they oil it up to keep it from rusting while on the shelf, just like rotors and drums. Then again, I would think that it did it all the time, and not just on takeoffs too.

My headers are stainless, and those are what I was referring to when i said mine smoked.

If you have oil in your intake, it still goes back to the cylinders. PCV system. Blue smoke is bad. There is another, although rare situation. The master cylinder can leak into the brake bladder. If the brake bladder (power brake booster) is bad, you will notice a vaccum loss. Possible loss of RPM's And always replacing brake fluid. Very rare though.

I had an old Honda Prelude that did that! It spit out white smoke though, IIRC. It stunk like hell too!
