well was going home friday night,and when i pull up to a light i notice a good amount of white smoke coming from under the car , i thought it was just from the really really cold weather, so i just dont think about it and head home. today i took the car to the gym and on the way the smoke is just everywhere, i habe a breather on the valve cover and smoke is just coming out of it never happend before , so i drive it home, check the oil i doesnt seem milky or anything like that but im not sure on what to do. i was gonna tear it down tomorro it has 150 miles since i built it

410 stroker,4 speed, indy rhs heads ported, 850 holley dp, eddy air gap, magnum 306s comp cam,.1-6 hughes roller rockes

i took the breather off the valve cover and it DID have a milky residue, what do i do??

glad this happend in the winter and not summer time

head gasket?? what thickness would you guys recommend.
:wack: :mumum::violent1:
 
Could be a few things does it smoke after you stop and then take off out the tail pipe === a bad valve seal
Does it smoke out the valve cover === bad rings may have broken one
May be just a leak or a blown head gasket.
shoot a short video so we can see
That really sucks :wack:

it will smoke when stopped and during take off, its kinda hard to tell , but it smokes out of the valve cover breather i have on it, never did it before,ill shoot a video tomorrow before i tear it down jeez i thought i coulda at least reached 1k before i had to tear it down not 150 miles well this sucks
 
Do a compression test, then add a little oil in the cylinder and do the compression test again. If the number goes up, the rings are the problem but if it doesn't its something else.
Also did you use break in oil/regular oil with enough zinc in it? 150 isn't enough time to completely break in the motor.
 
Did you stagger the ring gaps when you assembled it? The rings will rotate as the engine runs, and the gaps can line up. With only 150 miles, I wouldnt sweat anything unless it develops a miss or shake, or an obscene amount of blue smoke comes out the tailpipes constantly.
 
If its smoking that bad out of the breathers then the rings aren't seating for some reason, even on a fresh build the blow-by should be almost Nill if done "right", a tad bit of blow-by for the 1st. "50" miles is fine, Now do you have a PCV hooked up or is blocked?
 
What does the dipstick look like?? What does the coolant look like? Plugs?? From your description of the breather, sounds more like coolant in the oil?
 
When you take of the rad cap does it bubble over ?? If it is over pressurized it is likely a head gasket.
 
Hey Dustya, sorry to see you're having a problem. Does/did it smell sweet like coolant? Like few of the other members noted, the first thought that came to mind when I read your post was that it is coolant related, i.e. coolant in the combustion chambers. Hope you get her sorted out easily and inexpensively.

I'll try a compression test, I used regular oil with a good amount of zinc.

My machine shop assembled the short block for me I did the heads intake etc. at night when i drive I can't tell if the smoke is white or blue cause everyone out here has blue halo headlights lol ima go check now hope its nothing major

Yea when I give it a little bit of gas smoke just comes inside the car,( my heater blower. Hole is not blocked) but it never did when I first drive it:/

The dipstick looks fine I haven't pulled any plugs yet but I'll go pull a couple what should I look for on the plugs??

that was my first thought because a friend ha the same problem except he didn't have smoke coming out the tail pipes and he had coolant on the dipstick on the opposite with smoke out pipes and no coolant and dipstick( however I better go doubLe check that just to be sure ).

And thanks ihope so too
 
Unless you're not running a thermostat, the coolant should not bubble. specifically, crank it up cold with the radiator cap off it. it it bubbles, you've got compression leaking into the coolant system. Best case: Blown head gasket, Worst case: cracked head. Again reading your plugs'll give you final word. If they're anything but the usual tan, and in particular, if only one or two are different from the rest, you've found your problem.
 
You can rent/borrow/buy a cooling system pressure tester (Even Harbor Fright...yuck!) to truly see what's going on in the cooling system. A coolant leak or blown head gasket may or may not show up as bubbles in the coolant.
Compression tests will show things like worn cam lobes, but a leakdown test is your buddy.

Pull all plugs, look for ones that look "different", go from there. Smell the smoke, as mentioned. White smoke=coolant. Blue smoke=oil. Black smoke=fuel.

And if it's cold and you've only put 150 miles on it, are you even running it long enough to get it HOT? Let's face it, a cold motor, exhaust, etc. (i.e. "the system") WILL make a lot of water vapor when it has cooled off. If you're not warming it up, short-tripping, etc, you can have HUGE amounts of water buildup in the mufflers that takes a LONG time to boil out (Remember, all condensation may run to mufflers, and then overnight makes ice, which takes awhile to cook out.

If there's no smell to the "smoke" other than exhaust...drive it till it's HOT and see what's up. 20 miles, minimum.
 
Hey thanks guys well I took a video I'll post in just a min and I took it apart already I pulled plugs and they are as followed

#1 light colored no oil on it
#3 was black with small amount of oil
#5 same as #3
#7 same as #1
#2 dry and light and light colored
#4 light colored but with oil not sure if oil is from when it was rolling down from breather
#6 dry light in color
#8 dry and light in color

I'm going to pull the heads right now and hopefully worst Case scenario it's the head gaskets

Do a compression and leakdown test first that may help tell you what's wrong before you go tearing the engine apart...

Intake leak on #3 and #5??? When you pull the intake check that intake seal.
 
Yeah compression test it before taking it apart. That will give you more info on what to look for. Hope it is something simple and you are back on the road soon....
 
lol good luck guys he already has one head off. He said it was milky under the valve covers.
 
oh man!!......he SHOULD have done a LEAKDOWN test BEFORE pulling the heads......that will tell you what is wrong......yall young guns get way too ahead of yourselves! slow down, do some tests first, don't just rip **** apart, makes it harder to find out what it really was....
 
His car is his DD, he doesn't really have time. But hopefully it is it so he is done.
