 Subject: blown headgasket???
IP: Logged
Message:
today when i went to pull my camper home it started to miss reall bad, the next thing i know it is blowing white smoke all out of the exhaust. when i got it home the first thing i started to do was check compression on each cylinder. all of them were around 180-190. one of the plugs was real whitish looking, i figure this is the cylinder giving me problems. i started it up and let it warm up to see if the compression was still around 180 and it was. could there still be something else wrong other than a blown head gasket letting coolant leak by? there is also quite a bit of coolant blowing out of the exhaust. anyone have any suggestions before i start tearing this thing aprt tomorrow morning? thanks ahead

You better hope it's a head gasket. If you were not overheating and blowing white smoke then it's a good chance that you have a cracked head.

Check for a bad blown intake pan gasket. Take a flashlight and look down the throttle body with the butterflys open. If you see a lot of oil, pan gasket. When it sucks in you can suck oil spray from the valley causing smoke, if blown real bad. The missing would be from the loose of vacuum.TSB out about this. Speedtweaks makes a replacement pan kit. You got to take the manifold off anyway, install this kit. If you see other signs of a headgasket then pull the heads. If you have a v8 an M1 manifold would be a good addition in place of the pan kit.

You should do a leak down test to try and pinpoint the problem and go from there

well i pulled the head off and both the head and gasket are fine. the exhaust valve is really white looking just like the plug. coolant has to be getting in there somehow. where else could it get in? isn't the gasket or a cracked head the only way?

Intake manifold gasket is on the list.
If it was that, you should have a funny discoloration in one of the intake ports of the head.
And the last thing on the outside chance (I've only seen this once) the cylinder wall. If you want the "Backyard" test on the cylinder wall here it is.
Clean the area you want to test well
Stuff a rag over the piston and make sure the piston is at the bottom.
Lightly spray something like arid extra dray antiperspirant on the clean area.
Now what that will do is identify if you have a crack in the steel. You will see a line due to the contrast.
Other than that, better get the heads pressure checked.
I hope this helps

don't beleive it is the intake gasket. the intake side of the head looks just like all the others. the exhaust side is the one that is discolored, like a whitish color. need to ckeck for a crack in the cylinder wall next.

I was hopeing for a sucked in intake gasket, but with a groove in the cyclinder wall it is not sounding good. Might magna-flux the head first but it just dosn't sound good. Good luck with the dealer. If you have documented trouble like this you still may be in a position to get it fixed by Dodge. Good Luck.

not under warranty anymore. its at 48000 miles. you would think though if i get ahold of someone from chrysler about this that they would do something. there should be no way i could have cracked that block except for some kind of flaw in the block itself. the thing was only running 210 degress when it happened. i have done nothing at all to the bottom end of it. think i'm going to get ahold of my local dodge dealership and see what they can do. the next stop is going to be a lawyer if the dealership doesn't want to help.

before you go condemming the block, where is this groove/crack you feel? If its towards the top of the cylinder, it might just be the ridge from the cylinder wearing. I would double check the gaskets to make sure that is not your problem before you tear apart the rest of the motor.

You might want to try putting the head back on and pressurizing the cooling system just to see if anything does come thru the crack but this might not show as the engine wont be at operating temp

i figured out that the places in the cylinder wall are just grooves, how they got there i don't know. they are nothing major but you can feel them with your fingernail. two of my friends checked it out said that the grooves are nothing to be concerned about. i'm taking the heads to get checked out in the morning. hopefully the heads will tell me something. i hate to put it back together if the heads are ok.

Grooves in the cylinder wall aren't exactly -good-. If they are small enough I guess you can leave them, but your going to have rings going out in that cylinder before all the others. You've got it half apart now, it's up to you what to do. Put it back together or pull the engine and get the cylinder's honed. Thats a complete teardown though...
Just because you can't -see- the crack on the heads doesn't mean it's not there! It could be cracked in an intake runner, or around a valve guide. You said the spark plugs were white and the headgasket was a-ok? How very odd...
Time to order R/T heads if those are shot!

yep the gaskets are fine and you can see where the coolant has been burned in the cylinder. the exhaust valve and stem are both white and so is the plug. if the head is bad i'm going to go to jeggs here in ohio and get a set of heads from the they are only like 363 a piece i think.

dropped off the heads this morning. he magna-fluxed them when i was there but didn't see anything. the one was warped alittle though, he said 6 thousandth. he's cuttinf off 10 for that. he is also going to pressure test them to make sure there is no leaks inside, i'll find out about that in about 3 hours. what does everyone do about the little lip that sticks up on the fel-pro 1008 head gaskets. the little lip sticks up and is rubbing on the rubber intake gasket.

when i pulled each bolt out i looked into the holes and you could see coolant at the bottom. all the head bolts on the bottom were this way. not for sure about the ones under the valve covers though. i got some hig temp sealant to seal them up. i know when i fired it up last night coolant was coming out of the lower bolts on each side.

did you make sure to drain all of the coolant out of the block? when you took off the heads, some might have leaked into the holes.

yeah, i took a shop vac to everything when i pulled the heads. it was more than just some sitting in the holes. when i fire it up quite a bit was coming up out of them and when i took them out today to put some sealant on them there was a bunch in the bottom of each hole, like the coolant passage was running right under them in the block.
