#13 of 19 Engine Bearing Noise On Start Up by 57TanShoe

Nov 26, 2008 (3:00 pm)

Hi all. Got an engine noise that I'm trying to figure out and would appreciate any knowledgeable posts to offer ideas. Bought a real nice '99 F-150 a while back, it has the 4.2 V6 with 183K miles. Truck looks better than most with way less miles, so I feel sure it was well maintained. I bought it from a guy that lived a couple hours drive away from me, and so met him at a store on a major road that would be easy for me to find. The engine was warm and the truck drove out great. Next day, and every cold start since, the engine makes a bad bearing type noise on start up and the noise lessens after about a minute and is gone in about two minutes. I removed the accessory drive belt, still makes the same noise. Something internal for sure. I've used a stethoscope and can't really pinpoint any exact location, other than it sounds like it's in the front half of the engine. A mechanic buddy of mine said he would guess that it has some oiling problems with the camshaft bearings and one of them is making the noise until it gets enough oil to it. Sounds logical but I'd like to hear more thoughts on it. I have a half dozen vehicles and only use this for occassional hauling of bigger loads than my little Sonoma can handle, or if I need the 4WD. It's been driven only a couple thousand miles in the last year that I've owned it, but I am leary of taking off on a several hundred mile trip to haul a car or something. Don't mind if it dies close to home, but don't want to get stuck very far away. Any ideas on the possible cause would be greatly appreciated.

Sounds like excessive clearance on a rod bearing to me. It will be noticeable on cold start and then go away as the bearing warms up and expands a little. I had a Suburban that did it for years, and the person I sold it to still drives it.
It may not be any problem for a long time, but it's an indication that the engine is worn, and at 183K miles I'm not surprised.
If you rev it in neutral then let off on it quick, do you get the noise when the engine is warmed up? You may have to punch it kind of hard, like to 3500+ rpms.
I has this occur on my MGB also, and found that one of the rod bearing shells was broken in half and worn bad.

#15 of 19 Engine Problems..not sure what it is..Please Help! by smc0407

i bought a 2001 pontiac grand am SE a couple months ago. When i bought it, it had a good amount of miles on it. But i needed a car and it was cheap. When i got it, i knew it had a coolant leak but that hasn't caused me any problems..other than having to constantly put coolant in it. When i drove the car home..it had been sitting for a while previous to that and wasn't drove much at all. It had some oil in it but it was old and nasty. I took it to have an oil change & have all the fluid changed. when i reached my 3,000 miles and was due for another oil change..my change oil light came on. I knew i needed to get an oil change very soon. well, the night before, i was going to take the car to get one..i was sitting at a store..had my car running..it hadn't been running for long..and all of a sudden it just shut off. so i turned the key off and just sat there for a few minutes and then cranked it back up. when i did, i could tell that it wasn't running right. it was like a spudder. so i imediately turned it back off..and so i checked my oil..and there was no oil. even though i do not have an oil leak..there was no oil... so i bought a quart of oil..put it in there..hoping that i hadn't completely ruined it. and then i cranked the car back up...it continued to run weird...i pushed the gas a little trying to get the oil to circulate through the engine..and it just ran horrible...so i was going to pull my car to the side of the building so it wouldnt be in the way..and when i went to reverse it back fired..so i put it back in park and turned it off. I dont think the engine is blown..but then again i do not know. It still will crank up..but it doesn't run good. it's not driveable. Someone said it could be the timing. that it could be off. I also have the problem that i've read a lot of other people have..with the security light comming on & it not wanting to crank for atleast 10 - 20 minutes. . Also my trac light stays on. my service engine soon & service vehicle soon lights stay on. but i've had the engine checked out previous to what has just happened & everyone has told me that my engine was in good. If anyone could PLEASE help me..i would greatly appreciate it...this is my only transportation and need it fixed as soon as possible. Thanks

You didn't say where the coolant was leaking. Was it leaking out on the ground or was it just disappearing and you were replacing it?

your coil housing has a short in it. replace it and your car should run fine. the car has a multi misfire cylinders code if you scan it.

#18 of 19 noise?? i am puzzled by justin26

Apr 30, 2009 (7:15 am)

i have a friend who bought a wrecked car and had it fixed. it was a front end crash. after it was fixed there is a constant grinding noise it sounds like and exhaust noise but its too constant to be that. i have another friend with the same model and circumstance AND the sme noise. its not a wheel bearing noise because they were replaced with new spindles. it is a constant noise when ever the car is over 10 mph. any help would be awesome thanks.

Did you ever find out what caused this in your car?
I have an 03 GA 3.4l V6 - new plugs & wires, coil packs, new fuel pump, swapped MAF sensor & fuel pressure regulator (no change) car runs rough acts like too much fuel, cat turning red, putt putt sound...SES light on and was coding P0300 random multiple misfires. Not losing oil, not losing coolant, no overheating. It is going to the mechanic's but it would be nice to have more of an idea of what it could be!
