its been sitting off for about 2 months, i just turned on and it is thick, does that mean bad rings?? what else can it be??? this sucks...what would the cost of fixing something like that be??? guesstimating..

Fliptard

White smoke? Burning coolant, bad headgasket. Get an OEM headgasket kit and pull the head. I use Felpro as well, and also a place called J. I. S. for my gaskets, haven't had an issues with them yet.

KtHaNxBai

is there any other way to tell if the headgasket is bad???? as far as visual?

Fliptard

Leak down test. compression check

DeCePtEgRa

Drop some oil from crankcase onto a hot surface, if it bubbles coolant is mixed in oil.

KtHaNxBai

ok, i did a compression test, they came up
210,210,190,200....as i pulled the sparkplugs, they were drenched in oil...could that be the rubbergaskets on the valve cover??? and can tht oil be seeping into the spark, thus causing the smoke???HELP!!!!

KtHaNxBai

oh, all the tests were basked on a 6 dry crank test. meaning 6 crancks then i got the number

DeCePtEgRa

As long as the engine was at op temp, and all the plugs were out when each cyl was tested. Burning oil will be a blue smoke, black is fuel, white is coolant.

KtHaNxBai

engine was cold when i tested it.

KtHaNxBai

all the compression test that i read was cold engine. never read that the engine needed tobe hot? yes all plugs where out.

Motor needs to be at normal operating temps while doing a compression test with fuel supply disconnected and keeping it at WOT while cranking.

Fliptard

yes, let the car warm up, pull Injector fuse under hood, do each test again.

You could also do a pressure test on your coolant system pull all the plugs out and see if you hear air excaping into the cylinders

210psi per cylinder(especially at cold crank) is quite high for an LS, unless its a vtec engine. There is probably coolant sitting in the cylinders from a bad headgasket which is causing the high compression readings.

my jdm b18b or LS, is fresh only 2500 miles and it had 175psi across the board at running temp, compression test(dry).

DeCePtEgRa

Disable ignition by unplugging distributor not sure if there is injector fuse but I could be wrong too

first off i would take it for a drive, bowt 5 to 15 min's should do. if its still smokeing when you get back do leakdown and compression... most of the time my car will smoke if i havnt started it for awhile. by the time i get to town its gone

I had the same problem, same questions,.... The fix... A new head gasket! I couldn't figure out why, if the gasket was bad cuz the plugs were drenched in oil and not coolant. The plugs were very oily, but if I payed closer attention to the thickness of the mysterious fluid on my plugs, I could see that it's was very watery like. Not just only oil!

Fliptard

Yea, you need a new headgasket.

KtHaNxBai

i hope thats the fix...

dickdragon

Don't forget to check head n block mating surface. Make sure it's nice n smoove!

standy xsi

if it was fine before you parked it up i dont see why it will be headgasket..

just take it for a 15 min drive before anything

also all the seals will be hard so you might loose a bit of oil and water, hapens to every car. you have to run them back in, especially valve seal's where old oil has been.

dont jump straight to headgasket and people stop saying it without testing
