Supercharged 3800

Recommended Posts

Hello All,

I bought a '98 Regal GS a few days ago, since it has the same powerplant as the Riviera, I thought I'd ask a couple of questions:

1: I asked the original owner if they'd changed the supercharger lubricant,

they hadn't. The car has 67K, is this something that needs to be done?

2: I'm used to turbo cars, does the s.c. need a cool down period as the

turbochargers requre?

3: On turning off the car I can hear a metered "ting" or "tick" as the car is

cooling down, this will go on for a few minutes. Is this something particular

to this car? The sound seems to be coming from mid-body, not the engine

compartment. Could it be the cat? (no other symptoms and it passed

emissions testing).

Thank you,

Jim

2: I'm used to turbo cars, does the s.c. need a cool down period as the

turbochargers requre?No they dont require a kool down period

3: On turning off the car I can hear a metered "ting" or "tick" as the car is

In agreement with everything Rivieraman answered, EXCEPT having the dealer change the supercharger oil. It is one of the easiest things you may ever do with your Riv.

Just get a new turkey baster from Walmart (rubber suction ball on the end), attach a short length of small diameter rubber or plastic tubing to the end, and suck away. The job isn't dirty or hard (in my opinion). I would hate to pay a dealer tech $50 to $60 labor (plus the oil) to do the change. But, that's just me. The supercharger oil is available from the GM dealer's parts department. Get two bottles. You'll have a little left over, if I remember correctly. John

As a previous owner of a 2000 Regal GS (loved the car..if it wasn't for its electrical problems but mechanically, it was great).

  • SC oil should be changed every 50K.
  • I never let the engine idle after a long drive. Never had a problem with the SC.
  • I use to hear a 'ting' only after a looong drive and when turning the car off once parked in the garage. I thought it was the catalytic converter but it wasn't a issue.

FWIW...mechanically the car should be a gem. The main problems I had with the car were electrical - specifically having to due with the ABS system. Brakes worked fine but the electronics that monitored the system (and would prohibit the ABS from working) failed three times (twice covered under warranty at $2,200 each service). When it failed a third time (at a cost of $1,900), for myself it wasn't worth the cost on a car appraised at $5,000.

It can also be the exhaust crossover that runs under the throttlebody ticking as the noise. I let the dealer do the oil once and it wasn't bad but $$ but it's super easy and cheap so I changed my coupler for a ZZP unit at 100k miles and did the oil again then myself.

Amazingly fun cars and 98 has the standardized PCM so you get a lot more tuning options than the 97.5 like I had. Only downside is the funky design of the washer bottle and the slightly more restrictive air inlet system.
