so heres a not so nice update. did the plugs as prviouse stated, and got the new oring on the injector. no leaks anymore. however the noise and the running issue is still there. my buddy took a video of sound on his phone. if anyone has a video phone so i can send to them pls message me so i can send it to them. maybe if its heard. im running all outta ideas on this one

 

send it to your email then upload it to youtube

 

Could be bad or low octane fuel, go get some octane booster and some Seafoam.

 

was gonna try that but for some reason when it was sent to my email theres no sound. but on his phone theres sound lol. ill see if he can do it from his phone.

 

ok heres the link. no sound in email but got it on here lol http://www.youtube.com/watch?v=9KgkptwA6QY

 

Man that sounds like some tappet noise.....Once in a great while,when I first got mine,I'de start it and notice the oil pressure was up on the high side and it would come with that same tappet noise....sounded like all of them going off,it's fricken scary but it wasn't all the time.I ran a mild detergent through my engine for a couple weeks and changed oil/filter...serviced the pcv AND the little breather vents on the back of the heads....now it's gone.....I ONLY had the noise whn the oil presuure read high also....confused me.
If you guys have any insight on this I'de like to walk through step by step myself. I think I just got lucky an it went away,don't think I repaired anything...
Are there any common causes of this?

 

def is scary. almost sounds like the damn thing gonna blow up. i really just need it fixed so i can sell it. also moving in 2 weeks and dont have time to mess with it anymore and on top of that has to be running in order to take with me if it doesnt sell

 

I hear ya..scared the &*^%@$&^@% outs me when mine did it...You've done the plugs so that's off the table ...Have you tried the seafoam and octane booster?

Also,these 4.7's are particular about oil level and viscosity....make sure you're not over or underfilled and that you're using 5-30 in it...We'll see what the guys here advise an anything further, I'm sure they've dealt with this before...

Also,If you haven't yet,read through the DIY section, you might find a couple things to check while you're waiting for some advice....

 

havent tried the booster or seafoam just yet. i did however check my oil and thats fine. but i also did notice for some reason my oil gauge is sittin normal an then itll drop to 0 and then go up again. it will do this the whole time its running. but its def full an not to much

 

o and dint think bout telling this untill now. this sound just happened outta no where. was putting it out for sale an got like 1 house past mine an it ran rough an died on me an started knocking. not that this will really make a dif but incase that helps some
