This is almost always indicative of wear in the bearings that support the ends of the s/c shaft. It is about the only thing that goes wrong with the s/c - which is generally a good unit. Some shops will tell you that you must replace the whole thing - they are either lazy, incompetent or trying to take your money. There are places that will change the bearings on the shaft and it is fairly straightforward to do and not terribly expensive. The only trick is that GM will tell them the bearings are not available. This is when a good shop will take the bad bearing out and source the part themselves from a bearing supply specialist. I know an owner of a well established used car dealership who stocks a few of these bearings all the time and if he gets a s/c 3800 car in, he is all set to do a bearing swap with no fuss and little labour just to be sure his customers are kept happy.
No
no... its a 3.8 liter V6 motor...
The air filter is refered to as an intake silencer.
A 3800 supercharger can fit on a 3400 engine with some modifications, but it's not a direct bolt-on. The 3400 and 3800 engines have different mounting points and intake designs, so you'll need to adapt the supercharger and possibly the intake manifold. Additionally, ensure that the supporting components, such as fuel delivery and tuning, are also upgraded to handle the increased power.
I have a 1999 with the 3800 engine. The owner's manual says the horsepower is 205 without the supercharger and 240 with the supercharger.
Neglect to replace the supercharger oil.
The easys way i found out is to take the motor out first
To change the supercharger belt on a 3800 engine, first ensure the vehicle is off and cool. Remove the serpentine belt by loosening the tensioner pulley with a wrench and sliding the belt off. Then, take off the supercharger belt by loosening the tensioner for that belt and removing it from the pulleys. Install the new supercharger belt by routing it according to the belt diagram, ensuring it sits properly in the grooves, and then reapply tension to the tensioner.
Eaton M45 roots type supercharger
To change a 3800 supercharger, first ensure the engine is cool and disconnect the battery. Remove any components obstructing access, such as the intake manifold and associated hoses. Unbolt the supercharger from the engine, carefully detach it, and replace it with the new unit, ensuring proper alignment. Reassemble all parts and reconnect the battery before starting the engine to check for any issues.
don't think motor mounts will work - look for 92-99 3800
