did a headgasket, tb and water pump on my ls motor

i had the swap in a previous car that was wrecked. car ran fine had about 120k on the clock. then it was pulled and i did the work listed above and now i put it into my new car.

at first start up the car ran normal after acouple min. then car started to idle wierd and pour out white smoke. i turned the car off and then went over everything and started up again the car wouldnt run right untill i got on the gas and held it at 2,000 rpm then i shut it off after about 3 min.

i noticed in between cyl. 4 n 3 on the block there was oil running down the motor coming from in between head n block.

so i pulled the plugs from 4 n 3 and theres oil on the plugs

oil level was low but wasnt milky or dirty, and antifreeze level was steady

my thoughts

head gasket on wrong upside down or whatever
head bolts not tight enough
headgasket didnt seal properly


and ideas or help

thanks alot


UPDATE!!!!!!!!

and i did use a torq wrench but should i have done a lil tighter? Strected bolts? i kno arp studs you do a lil tighter if you have to re use them but headbolts? i had 2 buddys say they had this problem on each corner of the head there was a lil leak and the went like 2 ft lbs more n it sealed up

also if the headgasket is on wrong would the cause the plugs to have oil on them? and the car to smoke? and oil to come out of cyl 4 n 3?

the lastest update is a pulled the valve cover and the header off. i cranked over motor watching valve, cam movement watching everything turn over and it looks good. like i said theres oil in ports 4 n 3.

some1 told me my **** could be cracked or warped from over heating. hows that when it never got to temp?

also could this have anything to do with the rings? the couldnt have just went up? they were fine before.


sorry for all the ?'s i need help please dont forget to answer any

check head gasket placement and the valve gasket along with the spark plug gasket

ok so the headgasket was on wrongside up. so i bought a new one and put it on last night re did timing valves etc. puyt everything back together car started up and ran decent but still smoked. i shut it off after about 2 min n then called it a nite this morning i checked the plugs. the timing etc. everything was good. so i started it again once again it ran clean at first then started to smoke. car is idling high and i have no idea why. well i let it run for a lil and car steady smoked. i turned it off. checked oil and antifreeze both good. i pulled the header off and theres oil in each exhaust port and on header? now from the head gasket problem before im sure there was oil where there shouldnt be? like on a lil on top of pistons. or passages correct?

so is this just the oil burning off? or whats going on now.

headgasket should have sealed good. theres nothing on any corners or running down motor

then i checked the plugs and a lil oil on each plug?

im goin to do a comp. check now

comp. test was 185 across the board

I would guess it would jsut be oil burning off from it being messed up before.. But that's my 2 cents.

that is good compression.... and if you were dumping coolant into your exhaust system then it is still there..... more like the smokeing you are seeing is just burning off whats left in the exhaust system...... now about your idle i would check to make sure your throttle cables are not tight holding open the throttle body....

just my 02

in another car i've just replaced the head gasket, the white smoke came out of the exhaust for around 20 minutes ( HG was gone for a long time while still being driven). Did the car burn alot of oil before? also there might be excessive oil still burning off.

did you check to see if the head was straight? using a carpentry square and the head clean just run it across the middle of it the head and from the corners

well the problem is that i took the header off and theres oil in the header and in all 4 exhaust ports. like the car is still shuveling out oil. also the plugs have oil to.

now i know from the headgasket being on wrong the first time there was a lil oil on top of the pistons and there was prolly oil other places where there shouldnt be.

so im wondering if this oil n smoke is all the stuff coming out? like cleaning up.


thanks !

no the car burned very little oil before.

and thats good to hear. the car hasnt been ran for 20 min. yet i saw the smoke got bad and i stopped.

and yes i hope its all burning off. but im just wondering would it be pushing oil out to? like out the exhaust ports?

cant do that now the heads back on.





also what is a leak down tesT? would the be important to do now?

Leakdown test will show if your loosing pressure in the cooling system.

start it up and let it run.
