Hi
We have a similar problem
We recently had the Head Gasket replaced, Head Skimmed and cam belt replaced by a non-fiat mechanic. (I did not want to drive the car with the HG blown)
Since we got the car back;
It makes a low Grrrrrrrrrr noise at idle, As I accellerate, it gets pretty loud, then the noise goes away as I get to 2600, 3000 revs.
I also have lots of little bubbles coming up from the engine into the coolant overflow bottle. The Bubbles increase when I rev the engine and they are there when the engine is hot or cold.
The engine often just stops at low RPM, when coming to a stop or reversing; it just dies on us.
When Idling, the LED Light on the dash also flicers slightly
I will be taking it to a Fiat Dealer to have it diagnosed on Monday.
I will post the outcome next week.
My concerns are;
- Head Gasket was not fixed properley; or
- White Coolant/Oil Mix Gunge in Engine when HG was blown may not have been flushed properly and may have since have blocked oil filter; restricting oil flow. (hence the noise is less at higher RPM as more oil is forced through the filter); or
- Cam Belt Tensioners / Pulleys were not replaced or tension was set incorrectly; or
- Cam Belt has been fitted incorrectly... Could the Grrrrrr be valves hitting pistons? (I hope not); or
- Alternator is busy breaking apart; or
- a combination of the above.
I will appreciate If anyone here has had a similar problem and can advise what they think the problem is.
Many Thanks
VB Rgds
