4.6 not running right.
Alright guys, I've got some issues with my car.
Bout 3 weeks ago I had a nitrous backfire and blew the intake to hell.
So I replaced it.
Well when I did evenidently a bolt fell down the number 8 intake runner on the head.(I didn't know this untill about a week ago when it lodged itself in the valve.) So I pulled the head and got it out. (I pulled the whole motor to replace it. Figured it'd be easier.) I didn't know that this is what was wrong with it untill I pulled the head. I thought it was a bent valve or something.
Well I got everything buttoned up...
AND IT RAN LIKE ****!!!
Has a real rough shaky idle and the exhaust sounds really weird. But it does have nice power when you get on it. But the exhaust still sounds like ****
No check engine light.
I figured, ok maybe timing chains are on wrong. So I pulled the front cover. Chains did seem a bit worn out. So I replaced them.
IT STILLS RUNS LIKE ****!!
This time I also noticed that there was a bit of water coming out of the exhaust. Not sure why.
will be running a compression test tomorrow.
Someone please help.
I'm about ready to use this damn motor as a boat anchor.
Thanks,
Josh

something could have gotten down into the cylinder and scored the walls. that would cause a poor ring seal thus lack of compression. but you will figure that out when you do a compression check. if everything is tight then nothing to worry about. you could have forgotten to plug in a sensor or hooked up a spark plug wire to the wrong cylinder. just some ideas.
