#2216 of 2268 Re: Serpentine belt noise [imidazol97]
Jul 26, 2009 (10:20 am)
Eventually it turned out to be only the belt problem.
I tried removing the lubricants from the belt with a coarse brush, then windex and bounty, while the engine was idling. Actually it eliminated the noise for a while, but not for long and then it came back only worse.
Then, one morning I started the engine and while starting it made some snapping sounds. I drove straight to my mechanic and on the way there the engine started making continuous rattling noise, like the belt fibers were breaking and beating around. However, when I got to the shop and we removed the belt, it looked absolutely perfect, without any cracks or excessive wear.
Anyway, we replaced it and since then the engine runs smoothly without any noise.
Moreover, I just made two round trips to Cape Cod (1200 miles totally) in a week recently and noticed that my gas-mileage improved significantly. If previously it was making 18-19 highway mpg, now it makes 27-28 mpg. Can it be related to a new belt?
#2217 of 2268 CV Joint disassembly Outer joint
Jul 30, 2009 (3:18 am)
I'm trying to replace the outer boot on a 90 bonneville but it's not obvious to me how to get the joint separated from the axle so I can slide the new boot on. I was expecting to see some sort of clip but I don't see one. I've read and seen on the internet that some joints are removed from the axle by whacking it with a hammer in order to overcome a "circlip" . Is that what I must do.....force the joint from the axle? Or is there a snap clip some where that I need to remove with snap ring pliers????

I have the same issue with my '96 SE. First noticed it 5 or 6 years ago. One mechanic told me that I should stop driving immediately and replace the A/C Compressor, OR ELSE ... Another guy told me to stop worrying as long as everything worked properly. So I did.
The metallic rattling comes and goes. I had 2 or 3 "quiet" years, now the noise is back. In fact, it stops as soon as you start your A/C.
It does not seem to harm the engine, the only problem that it gets on my nerves.
It does not completely answer your question, but at least you can drive without too much worries.

How long have you had the Park Avenue motor in it?
Have the symptoms been there since the replacement?
Did you change the computer and PROM in the computer--or at least the PROM?
Feeling the type of stalling and getting more conditions about when it stalls would help. How many miles on the car? On the motor?
P071 may be due to MAF, vacuum leaks, and some other things. The MAF sensor can be cleaned with spray after taking it off-two screws, security type screws.
Fuel pump problem, low pressure after warming up.
Crankshaft position sensors do funny things.
The intake screen ont he end of the throttle body should be there. Is it? That is the honeycomb screen that straightens the airflow before the MAF sensor.
Try spraying carb cleaner around all the hoses and the edge of the upper intake. Some have found hoses dry rotted or split near the ends especially in areas that get some gas fumes or high heat.
Remove and clean the EGR valve.
Other mentions have been the lower seals on fuel injectors age due to the heat and need replacement--cheap and easy.
But diagnosis is important, otherwise you're just throwing money at the problem.
