Vibration from front of car.

[Blaack]

I'm usually pretty good with cars but my lack of GM experience leaves me questioning with my current problem.

I have a 1998 Olds Intrigue GLS. 3.8

When ever the car is stopped, ingear or not, warm or not, i feel a slight vibration from the front and can hear it inside the car. It is in rythem with the engine idle.

It has just appeared and I parked the car so if it is something serious I can get it to a mechanic before disaster strikes.

The only things I can come up is maybe a crank bearing or maybe a bent pulley.

Once again, the sound completely disappears when you press the gas or acelerate.

ive got a similar probelm, kinda sound like a 4 cyl diesel. but mine only happens when i brake. im think a mount or something in the brake assembly. also it only does it in the cold.

It does kinda sound like a 4 cylinder diesel. Not as loud, but kinda like that. I guess I'm trying to figure out if this is normal after miles start getting close to 90000 miles.

After all, there is only so long I can get up at 7 in the morning to take the wife to work when I work swings.

im jsut under 120k, this weekend ill get up early and figure it out. im thinkin a mount or something, with the wishbones id think theyd wear out pretty quick, i only notice it when the car is at a stop, with either braking or in park, thats where i think its the mount, but im not sure. for all i know it could be that mask over the top.

this sounds like a harmonic balancer problem. It the time-ing of these engines related to the harmonic balancer also?

Hmm...It could definately be that. Never crossed my mind.

As for the question, I don't understand what you're trying to ask.

my dad had a 1988 3.8L Ciera and replaced the harmonic balancer I think. Isn't there magnetic pick-ups on it or sometype of electrical advance = this could be the problem of your dieseling also. Does your harmonic balancer have a type of balance weight that may have fallen off? I will need to ask my dad what he did to his. I have the 3.5L.

Sometime a loose torque converter or flex plate connection will give you that rattle also. This happened in a Century 2.8L we had.
