#251 of 575 decelleration hesitation
Feb 03, 2007 (5:59 am)
hi y'all, i have a 1990 pontiac safari wagon w/a 3.1 6cyl engine - same as the buick century...135kmi...recently it began to hesitate and buck when backing off the accelerator...i had "woody" tuned up and the gas filter changed, but the problem persists and has gotten more dramatic...he has begun to idle roughly...would a 1990 have a engine diagnosis hookup...? if so would it be best to have a dealer track the problem... ?
thanks for any advice,

You may have a head gasket leak. The way to verify it is to check to see if your oil level is high. This means your coolant is passing thru the gasket into the motor oil.
If so, you need to get it fixed asap, as the engine bearings and other lubricated parts will burn up, and you will lose the engine. We had this happen to us with our Century about three years ago. I hope that is not what it is! Good luck!

I checked the oil - you were correct, the level was very high. I'm having it looked at tomorrow. Thanks for the help!

I have a 1999 Buick Century 3.1L V6. It has just over 120k miles on it.
I purchased it, and didnt even know it had a tick which would occur after the car was running for a minute... and it never goes away. It is harder to hear at higher RPM's (over 2,000) but it's still there.
I notice a lot of people have problems with engine tick at cold startup, but I have not seen any people post about engine tick AFTER a cold startup
What is wrong? Is it bad? Easy to fix? Expensive? Will my motor last? What should I do?
I purchased this car for winter use because I wanted to store my 1999 Grand Prix GTP 3.8L Supercharged V6

On my brand new 2001 century, already had a click.
The dealer shop and every service technician i have spoken with about it since, says this is nothing to worry about.
Just a nuisance!
Also, brakes have always squeaked a little in humid conditions.

My 1993 Century 3.3L with 47000 miles also ticks after warm-up and does not stop. When I listened close to the motor it sounds like its coming from the intake somewhere. Have you heard from anybody on what this is.
