dumb question but can you answer it ?

Ok so heres the deal ... a little white smoke coming out exhaust come out only one tail pipe ....
motor 235 dual intake dual exhaust, my question is if i have good oil pressure does that eliminate an issue with the rings ? Im going to due a compression test on cylinders this weekend .. just going nuts over my motor . Its white ish smoke ...

 

Good oil pressure does not rule out the rings. Do the compression test.

 

grayish/bluish white or just plain white? White is the color of antifreeze burning....gray/blue is the color of oil burning.

Does it loose coolant or oil?

 

I think is karma punishing you or that avatar pic!!

Doc.

 

It could be worse..............he could have used this one:

 

One thing I always liked about dual exhaust:

You can easily tell which side of the engine has had a head gasket blow when the steam starts coming out the tailpipe.

 

i would say whiteish gray . back 3 plugs were wet with gas.. meaning its not being ... burnt . last 3 plugs cold to touch after running 5 min ... front 3 are warm .

 

to teat head gasket ....test radiator pressure .. or compression test per cylinder ? school me ... .. easy with the A pic.

 

And which side would that be on the straight six in question?

 

I had a 235 that started doing that..It was almost like a steam vapor, now follow me here............I replace the cap and rotor. (after hours of head scratching....) solved the issue.

 

check oil to see if it milkey when cold, could be head gasket, pressure test radiator,

 

Huh??? Could you repeat that one please... Thanks!

 

Check the dip stick. Look for gray color, or bubbles in the oil

 

Double post?? Replied to you about this issue an hour ago. Your carb is bad!

 

This is probably nothing even close , but when I was building my coupe I started the engine one day and as it warmed up it started to blow a little white smoke from one exhaust pipe, then a few minutes later from the other. It was a brand new crate engine ...what the F. It was idling in the garage with the door open. I was getting really upset, what the heck is it, valve guides, but how could it be. Then I noticed some little chared black things on the floor behind the car, some were smoldering a little. I picked one up and it was.....DOG FOOD ? I sometimes left my Beagle in the garage where I had an attached ouside kennel. I left dry dog food for her , and apparently a mouse had been storing the dog food in my exhaust pipes.

A couple hard throttles and that stuff came out ot there like birdshot out of a shotgun.

 

Years ago I had a 216 do it. It had some wear in the distributor shaft but a new cap & rotor fixed it.

 

That'd be front side or back side.

 

Two threads on this and lots more info on the other one.
if you want guesses, there's plenty of them.
You're first move AT THIS POINT NEEDS TO BE A COMPRESSION TEST.
Sounds like you washed down the cylinder walls because of the Carb. That's also a guess.

 

One quick test remove radiator cap. Fire up engine. If the water gets shot out, from compression getting into cooling water, blown head gasket or maybe crack. Of course that is if the blown part of the gasket goes into the coolant!! But it is quick and easy.

rear header on the 6 . which is the same side blowing smoke .

 

My 327 started puffing white out of one side after having the 2.02 heads completely redone. It appeared that there was a slight crack and he didn't magna-flux like he said he did. New heads, no problems.

 

so i just tested the pressure on the radiator ... and it held pressure ...

 

That radiator don't have anything to do with flooded carbs, washed down cylinders, certainly has nothing to do with possible worn rings from the washdown, and very little to do with gas fouled plugs or three cylinders not firing.

But its good to know your radiator and cooling system hold pressure.

Compression test is what you need.

 

Front or back half I suppose...

Assuming it's split manifolds or duals with no X pipe, it's an easy way to narrow down what cylinders are being problematic.

 

I think I'm in LOVE, I said I think alright.

 

You can find a crack in the head if you pull the head. It will have one very clean combustion chamber and 5 dirty ones. A cracked head will puff white smoke until the engine warms up and the crack swells closed.

 

put the front carb on back and the back carb on front and see if the carb is the problem.

 

Since the manifold center port feeds cyl 3 & 4 it is unlikely to be a fuel problem. 3 is firing, 4 is not. Ignition seems most likely. The front 3 appear to be firing, the rear 3 not firing. Something is making the rotor skip every other contact. Have you put different wires on 4,5 & 6?? Maybe they are not seated in the cap. Have you checked for spark on 4,5 & 6??? Plug condition???

 

He said "warms up" and "crack swells closed"..................

 

Chuck he might be thinking of a reverse cooling system
