help! strange noise from bonnie and power loss
 

Strange noise today its like a squeaking noise coming from the front end, not just squeaking but like when something hits another object in rotation. Its too dark out and just heard it, it even stalled while going into my driveway. In traffic lights my light would dim for like a second like it was struggling.

whats going on?? :x

thats pretty vague...

got one of these??? ;)

yea, i do I dont think its the belt. I dont know how to better explain it sorry.
and sh!t I had my lower intake gasket replaced yesterday I hope its not coolant mixed with oil.. and oil level seems low when I just checked it. omg im pissed

only under throttle? only in gear? more details needed

idle and gets louder with throttle, coming in park/netural/drive (not the tranny)

does your temp gage rise?...when my Lumina's uim failed it would get rough during idle and the temp gage would rise really fast....but it would smooth out when given gas..it actually ran like this for a few months before it died completely..it was a 3.4 though..not sure how a 3800 would react...

Hmmm....squeaking, but like something hitting in rotation at idle. Not coming from the belt. Maybe an alternator bearing going out? - That might explain the stall and the dimming too. But you should be able to hear it pretty clearly at the alternator if it is.

An exhaust leak between the manifold and cylinder head can make a squeaking, ticking kind of noise.

To see if the noise is coming from something driven by the belt, remove the belt and start the engine. Don't run it for more than 30 seconds or so - you will have no alternator and no water pump.

Belts squeal when they slip. And when they slip they become glazed, and sometimes leave crumbs of rubber near the pulley they are slipping on. Sometimes a new tensioner is needed, other times a driven appliance is turning too hard because of a bad bearing or damaged internal parts.

Take a good look and listen in the daylight.

guys.. the engine is toast.
I just got the bad news from my dad, I'm at work now and pretty bummed out about this. Some guy quoted him for $1500 for an engine with 70,000 with the install.
Is that a good price? If i want the l67 I gotta buy the tranny to right?

the sound got louder as the day went on he said and its sitting in the street now. I didnt have time to start it to see how bad it was.
sucky week..

did you do the intake yourself or did a shop do it?? could it be related by coolant being in the oil?

the guy at the shop did it, and thats what I was thinking about too. Oil isnt supposed to be sticky is it? he supposedly changed the oil after everything was done but who knows what happened.

I have a pretty good guess. Coolant mixed with the oil and destroyed the bearings in the engine. My guess would be a rod bearing. Either it was driven too long with coolant in the oil before it was fixed, or the contaminated oil was not sufficiently flushed when the repair was done. Did the mechanic change the oil and filter at least?

For the repair to last after the oil is emulsified takes quite a bit of effort in cleaning the engine, a lot of fresh oil, and at least two new filters before you can call it "fixed." Most mechanics don't take the time to do be meticulous here. And the result is often engine failure. It is a good reason for learning how to do it correctly yourself.

It's really a shame. There have to be thousands of these Series II engines out there that have suffered a similar early death because of this curmmy intake manifold design. The trick in this case is to go against conventional "wisdom" and fix it with a sleeve, EGR air gap, and LIM gaskets BEFORE it leaks.

I dont think he flushed it twice just once. But i wasnt thinking at the time i picked it up. I picked it up at night, drove about 4 miles. Next day I drive 20 miles to school and back, around midnight is when this happened. I was pushing it in the highway but I always do and she takes it fine..

As for doing it myself, 1. Im a full time student and part time worker so no time whatsover. 2. Im not a mechanic but an engineer so dont have that experience anyway.

You never know. The damage might have been done before the mechanic touched the car. Anyway, the horse is outta the barn, as they say. And, at least this should never have to happen to you again. You now know how to avoid the problem.

Re the student thing: I hear you. Been there - done that! As for the car, just think of this as another expensive part of your education.
