So when I give any gas to my car, and it gets to around 2k in RPMs, it sounds like a rollar coaster- Like when the cart is going up the hill, you get that weird noise its really hard to explain, it what it sounds like to me LOL.

It sounds like its coming from the top right of the engine bay when I open my hood =x

Im puzzled

Its a M/T could it be my clutch? its been really bad latly

Thanks!
 
is it happening in every gear? may sound dumb but it could be that your bogging the engine by being in too high of a gear

Yes every gear, even in neutral, I rev my engine and you can hear it.

Detonation probably. Is your CEL on?
 
GSGoinFast said:
detonation?? :rolleyes:

but do you have a CEL? does it sound like a misfire?

I do not have a misfire, and my CEL is not on.

It does it in neutral, just not so loud, when in gear, its really loud,
 
I made some really bad videos to try and capture the noise ( you have to right click and save as) Angelfire is the sucks. But they let me put up videos so meh

http://www.angelfire.com/crazy/wcw/Movies/Video_1.avi

You can hear the noise im talking about 0:26 and 0:39 in the 1st movie.

http://www.angelfire.com/crazy/wcw/Movies/Video_2.avi

You can hear it almost all thoughtout the 2nd movie

Theres another noise there, sounds like a peice of metal vibrating and shaking, thats not the noise im talking about.. I thought that noise was my heat shield (Obviously not since its gone) but its made that noise since I've had it and im not to worried about it, should I be? LOL

THANKS alot whoever helps/helped me out :cool:

The car is all stock

and sorry, my camera is pretty sucky
 
A friend checked it out and said it sounded like a lifter


these expensive to fix

and hazordous to drive with?

Sure, you ever heard an engine under severe detonation? It makes the most god awful racket you can imagine. The only reason I mentioned it is because I had it happen to me a few months back

lifter.... no no no no no
more like a spun rod bearing that is somthing that the 420a likes to do it gives a real ugly tiking noise


Is it dangerous to drive the car with it like that? Will it do any major damage to the engine?

Is it a expensive fix? =x

Thanks


It also dident start until I added Oil to my engine, my oil light came on, and I added some mobil one into it.

But I did drive it a little while with the oil light on =/
 
Ouch :( From everything I've read during my time in the 2GNT crowd, the main cause of the 420A engine boom...is starving her of oil :notgood: Driving her around with that oil light on could very likely be where you went wrong. Don't take my words to heart just yet though, there are lots of other possibilities that all of us on here can come up with :D

yes

If you dont know how to rebuild an engine... yes

The oil you added could have dislodged a carbon deposit and it lodged itself in the lifter...

SynthRocker said:

that could have been enough to spin a bearing.
 
well lifters sound more like a ticking noise than a loud "roller coaster sound." when i had a lifter start ticking all i did was swap a 1/2 qt of auto tranny fluid with a 1/2 qt of oil on your oil change, if that doesnt work, then they make cleaner, where you pull of the valve cover and spray the lifters. lifters arent generally expensive to fix, if you spun a rod, then your lookin at something just a bit serious... :dsm:

1.is it dangerous YES.
2. MAJOR MAJOR MAJOR damage you could throw a rod through the block :barf:
3.your probley looking at about 1000$ deponding on how bad the damage is
the shop or whoever dose it may have to re-grind your crank down 1-2mm and use
over size rod bearings. Or if its not too just replace the bearings.
4. driving with little to no oil in your motor causes bad oiling in the journals due to there being no oil on them and will cause a thrown bearing.
5. get it looked at by a real mechanice ASAP
 
It's the GD rod bearing. it is definatly not no detonation. its not no misfire. Learn what you r talking about GsGoinFast. you work in a chinese food restraunt. you probably take your car to pep boy to get it worked on. you wouldn't know the difference between a snezze or a wet fart.
 
He asked if it SOUNDED like a misfire you prick. ####ing open your eyes. And I would be willing to bet Chris does ALL his own work, more than you could ever do. Now go order chinese so chris could deliver a foot up your ass.

Chris is a wiseman for a reason asshat
 
It maybe your fuel pump, i remember one of my friends had the same problem he canged the fuel pump and it fixed it
 
I was going to say throwout bearing. Simple yes, loud.... if it gets bad enough. It makes sounds throughout the transmission range 1First thru fifth, reverse and Neutral. They chatter bad and sound just like a roller coaster. Just a thought.

i dont think he would get heavy detonation at idle under no load though.

Dear God man, grammer is your friend please use it. Don't *try* to bash someone like Chris who knows a hell of alot about our engines. Not sucking up to him or anything but a dude who can custom fab up his own WORKING turbo kit gets a hell of alot of respect from me and he obviously knows his shit
 
big wow if he fabbed his own kit. how many of these engines has he worked on besides his own. i've done more than 15 of these engines. ive built 2.2 stroker all motor engines that will whip his own cars a!@. my 4 year old son could build better engines and bend intercooler pipe better than him but I don't have a son.

You make no sense what -so -ever, you need to quit spewing bullshit, I'd love to see that 2.2l stroker that could whoop a turbo 420a's ass, no matter how bad ass you build a stroker you still can't get to 200 horse. Shit is getting thick in here. Go play with your spider man comics
