Left school today, drove about 3-4 miles, upon entering my neighborhood the car started stuttering and as i come to the stop sign the car doesnt die out or anything, just stutters throughout the rpm range. Any ideas? Got home and popped the hood, sure enough theres a knock coming from what sounds like the pass head, pulled both valve covers.. springs and rockers look great. Thinking detonation, i did get gas at shell (beltway8 and telephone) after dropping a buddy off at hobby airport and being on E i put 12bucks of 93 to get myself back to 59/90 to grab my wallet. Just filled my tank at my normal spot and took a quick 2-3 mile ride and car is still ticking and not running right, seems to be getting worth! Get home ticking sounds like its coming from bottom of car now.. What do you guys think? Lifters? Rod bearing? Thanks Jeremy

Sounds like it may have turned a rod bearing, Sorry hope I am wrong

 

Sounds like something cut loose in the bottom end. Time to pull it and investigate. Sorry. Sounds like a rod most likely. There is a lot of distortion in the video hard to say.

 

Ok, this may sound out of whack...check your oil filter, I've had Frams internally collapse and the engine sounded like a rod knock. Also, I had a friend who had a supercharged ford engine, got some bad gas and the engine knocked, stuttered and stubbled and sounded like poo.
Good luck-hopefully you just got some shiet off the bottom of the gas station.

 

save whats left it sounds not verry good but anything could have happened but how it shakes when you turn it off ... check your oil look for metal then update what it is when you find out

 

no metal according to dipstick but will drain oil come monday, oil pressure is great as well.. ac delco filter

 

Hard to tell from the video just where your trouble is coming from.
I don't think it has anything to do with the quality of the fuel you put in it.

I have a suggestion. Before you change oil use a stethoscope to better isolate where the noise is coming from. If you dont have a steth a long screwdriver will work pretty good (handle in ear/tip on pan/valve cover/ect).

Sometimes it's a good idea to remove the belts to eliminate the outer rotating stuff on the engine but in your case I don't think it will help. Sound can travel far better than you might imagine through an engine.

If I were to guess I'd lean towards rod bearings but I'd isolate further before removing the engine.

I would not waste an oil change to "try and make it better" at this time.

I have heard dying airpumps make that much noise; not very many however.

I'd put money on having to remove the engine. Sorry!

Good Luck!

 

didnt u have another post about this ?

 

lifters....if its only coming from one side....spin a rod bearing it would have plenty of metal in the oil.

 

im goin to say a rod bearing but just dump the oil and cut the filter open and that will tell you whats up if theres metal then def spun rod bearing.

 

Tomorrow I will have some leads, Will keep you guys posted!

 

Process of elimination time. Check oil, lifters, springs....

 

Okay guys, after having to drive it to work.. there was a second outlook this time when the valve covers were pulled... Problem was found. I would like to thank everybody for the help, and hopefully I have helped somebody out with a similar problem!

Whats left of the PATRIOT GOLD!


Whats left of the factory ROCKER!

 

I had that happen to my 99 t/a on start-up with the whole fluttering and banging and eventually died. got out and wham! holes in the oil pan and right through the block with plenty of oil spilling out. Turned out a rod bolt was stretched and let the piston go up and hit the valve and ultimately busted the piston and rod.

 

Now knowing that you kept running the engine like that, you should make sure that no metal chunks are in the bottom of the pan, I would change the oil twice, and pull the head and make sure the piston is ok.

 

Yea.. Definitely the needle bearings are in the engine.. should be on the drain plug.. hopefully!

 

This happened a few weeks back. Came of my buddy's 99 SS. Car has a Torque V2 cam, PRC 2.5 heads, LS7 lifters, and a few other powertrain goodies (and everything on the suspension side). Nice car, 46k miles.

Went to do the first oil change, as he bought the car 2-3 weeks prior, and discovered what is in the picture. Valvetrain was noisy to begin with, typical sewing machine sound, no sign of a problem, he just wanted to put some Royal Purple in it. Those would be the needle bearings from a FACTORY rocker arm. Everything the previous owner upgraded, and somehow, someway, put factory rockers back on

Anyways, you may or may not see this on your next oil change.

 

i would def drop the pan and take off the windage tray to make sure no extra metal chips are lurking in there

 

Needle bearings won't get sucked up the oil pickup.. just might be a few bearings on the oil drain plug after initial oil change

 

Exactly. Wouldn't worry about finding the needle bearings in the oil. I'd just drain the oil, check for metal shavings, and go from there. How's your oil pressure?
