Thanks in advance!!!!!!!!!

 

it is running rough at idle and in gear also it is an auto dohc by the way e=what did i do ?

 

you have to be more specific. is car making any noises, smoking etc. if running rough after you pushed car to the limit you proly blew a head gasket. Check if there is coffe colored oil under the Cap. is there any antifreeze leaking from the engine. what color is (if any) the smoke coming from the back of your car?

 

it has the oil that color it runs rough at idle and in gear it doesnt smoke the antifreeze is the normal green ish yelow color i dunno how to be any more specific than that how much will a new head gasket cost and cvan i do that myself with my uncle and dads help?

 

So your oil is Coffe colored? (light brown) that mean that water is mixing with your oil. Thats not a good sign.

 

what is it a sign of id i screw it up bad how much will it cost help me out ?lol

 

im no expert, but I do belive you blew a head gasket, its the gasket between your head and your enginle block prety hard to replace

what other stuff could i have done beside that could it be my coil packs? or water in my gas some places round here have hat problem and i had just gotten gas lol

 

Young Man, please slow down!! You can get hurt going that fast. Also if you get caught going that fast , you will loose your driving privlige and be paying the Man some big bucks on a fine, not to mention how it would effect your insurance
Now, to your problem, With the engine running,pull a coil pack connector off one by one, when you pull one off and it does not change the way the engine in idling, or it does not cause the engine to stummble, that is the first problem to go to. Pull the spark plug out and check its condition. If it looks really, really, really clean, then coolant has breached the head gasket and is getting in the cylinder. If it is covered in thick oil, the oil has breached the head gasket.
If it is a gasket failure, you can save a ton of money by doing it yourself and learn to turn some wrenches. Get a FSM or a chilton guide and follow it. It is not real hard just very time consumming.
It took me 20 hrs and I`m a girl.

 

thank u and i will slow down i was just wondering how fast my max would go if i do this will u help me out if i ask u a question ?? but if coolant has got to the spark plug is the head gasket blown i am confused i dunno what is goin on!

 

Ask away young man, thats what this forum is all about. We are here to help each other.....
If the engine was running fine before you poored the coal to it and you have a cylinder not firing and is real dry looking, or wet with oil, you have a blown head gasket. How many miles on the engine? Over time, of hot and cold and hot and cold can eventualy warp a aluminum head. Heat is the worst enemy of aluminum. If your not sure it is a blown gasket, take it to a local repair shop and pay them their "car check out fee" and see what they say. It should be a minimal charge if any.
BTW, you do have a VE30DE engine, dont you???

 

I remember that gas problem around here... I think that problem is long gone by now, so you probably don't need to worry about it. Last I heard of that happening in Louisville was 6 months ago, I don't know about Madisonville, though.

And I understand, you're a 17 year old guy on the highway and want to test the limit... I've done the same. Just sucks when your car pays the penalty of a short power trip.

 

yeah it was running fine when i did my lil go go fats thing i am so mad at my self for that yes i have the ve 30 de engine i dunno what all the numbers mean but i know i love my car and i would love to fix it thanks yall lol!

 

you keep that up, and I'm gonna ask jeff to put that under your name
