HELP 1992 ssei woes
 

i ahve a 1992 bonneville SSEi...i jsut got the car today..car has 200k,,gm certa tranny, new supercharger,,,etc,,,engine was all dealermainted...in excellent condition

i was on the highway today and i noticed it lacked power,,,coming onto the onramp the service engine light came on,,the car died (no ps, brakes etc) and WORST LOW OIL PRESSURE

i turned the key to accessory and then on and yes again the car started was knocking and no oil pressure,,i immediately shut it off...luckily i was not far from home so i pushed it home

any ideas what the problem is??

i jsut checked the car it has been sitting for 3 hours

the supercharger is still very very hot i can barely even touch it

also i smelled some fuel

i am wondering if the supercharger is no functional and the engine was dumping so much fuel and it wasn't burning because the supercharger was not working

i tried starting it again and i think the knocking (weird nose regarldless) was coming from the charger

does this sound right?


i have to get it towed back to my work so i can check it more thoroughly


if the sc has no oil does it need new seals? or is it cooked??


also a side note..the cars boost guage was always ON FULL

even at idle the boost guage was reading full

mind u i jsut got the car...so i was looking into this..i took it for a test drive and this was happens..

Moved to 1992-1999. Please don't post mechanical problems in Performance and Brainstorming.

On some cars the gauges, have problems with the gauges going wacky and pegging themselves.

EDIT, I saw that the SC is knocking. Where did the SC come from, do you have a reciept to show where it was purchased?

I believe you have a FEW problems. Why are you asking about oil? Is it empty? Have you checked it?

The boost gauge should be all the way to the left at idle. Are the vacuum lines hooked up properly to the BCA and BCS?

my boost guage is all the way to the RIGHT on idle

i am asking about oil because all of a sudden when my engine stalled..when i tried to restart it.,,the cars oil guague reads it has no pressure...i checked the dip stick and there is oil in the crankcase

now i noticed 3 hrs later that the SC is still VERY VERY HOT

the engine is cool

CHECK the SC oil. It doesn't use engine oil. To find out if the SC is knocking, remove the SC belt and start the car. Not for long, though, as the water pump is on the same belt path.

TECHINFO at the top of the page may be of help to you in checking your SC oil.

i noticed on the highway the car didn't really pull..i ahve a 97 grand am 3.1 v6 and it pulls

could i ahve blown the charger???

i never even though to check the oil to be honest with you

dammm
i will check it tomorrow during my lunch i can toss it up on the hoist i am gonna get a general tech to check it out...thanx

The SC oil is accessable from the top. There's a hex plug in the S/C nose.

Let's take this one step at a time. When your SC is reading full boost (about 7-8 psi with a stock pulley) it indicates the SC is actually functioning. SC's don't 'blow'. Well, they do, but not in that sense.

Please follow the instructions above before jumping to more conclusions.

yes but when is start the car and it is at idle should the needle be all the way to the right..the needle it at the MAX it can go at idle and does not change when i am driving..should it be doing that?

also it sounds like its grinding or knocking,,it sound like SHIT

What your gauge is telling you is there's something plumbed wrong in your vacuum. Either in boost control (BCA/BCS) or boost indication (MAP sensor or gauge).

Ignore it.

You have knocking noises. Diagnose that FIRST. Noises become fatal.

Follow the advice above please.

Check the oil in the SC.
Remove the SC belt and start the car. While the belt is off, rotate the SC pulley back and forth. How does it feel?
Check the oil. What does it look like? What does it look like after running for a few minutes?

Are any vacuum lines on the top of the engine disconnected or damaged?

Well if the engine had stalled i dont think you would have oil pressure anyway, so i dont think that you would have a problem there unless there is no pressure when running (obviously)

Also where are you located? maybe theres a member close by that can lend you some assistance ;)

alright i will check tomorrow aabout the sc

thank you for the advice everyone

i am located in Scarobrough at Victoria Park and Ellesmere

thanx but yes currently when i start the car there is no oil pressure but i checked the dip stick and the level is fine..the guage is reading no oil pressure..after the stall..so i am wondering if the guage is faulty or if there are vac lines that need replacing...i will check this too tomorrow when i check the sc...

After a STALL the oil pressure SHOULD be zero.

What is it before it stalls?

Scar what? Be more GENERAL. State? Province? Major city? This is a WORLDWIDE forum.

after the stall i RESTARTED THE CAR and while the car was running the pressure read ZERO

while the car was running the guage reads zero while at IDLE the oil guarge says it has ZERO pressure

Hes right up the street from my work Bill ;)

If your oil pressure was truly zero, you would have no fuel. The PCM cuts off the fuel supply to stall the car if the oil pressure drops. This is to protect the engine.

Get an aftermarket oil pressure gauge on the car as a first priority.

XLR, I can sense and understand your frustration, but you have to understand ours as well. We are VERY good at solving problems from thousands of miles away if you follow our instructions carefully and answer our questions without jumping to conclusions.

We do this every day. Take it slow, answer the questions, and try the things we suggest.

Or go to a GM dealer and pick up a new oil pressure sensor (I recommend City Buick ;) its at Vic Prk & Lawrance ;) )

Rather than throwing money at the problem, I suggest actually checking the oil pressure with an aftermarket gauge, particularly in light of the fact that we have knocking and stalling.

i work at bob johnstons

i am gonna get some general techs to help me take a look
i jsut got the car
i used to have a 97 grand am with a 3.1 v6 and the engine gave me no problems
i was taking it for the first drive as its owner and this happens..

never mind then :lol:

Yeah mine ran like a bag of shit when i bought it, after i brought it to one of the Generals we found and fixed the problem and car ran GREAT, you will love it once fixed trust me ;)

Also what do you do a Bob Johnsons?

i will check all these things tomorrow

sorry if i sound a lil angry,,,i just got this car and its jsut crapped out on me,,i had to push the thing quite aways..its HEAVY

and to say the least i am frustratred...i can;t wait to rip into her tomorrow and get down to the issue...i will try everything u guys ahve reccomened to me,,,and again

Just make sure you get back to us with what you find out




Also lets see pics of the car, I want to know what it looks like No better year then a 92 ;)

i will get some pics up soon

Let's stick to the topic. We'll use this to diagnose your mechanical issues. Your other information and pictures can go in a new topic in Your Ride.

ok so i took the oil pan off

i spun a bearing,,,3 connecting rods are cooked :(

anyone have a 1992 ssei motor?? my sc is good...but i need a new motor now..not worth it to re-build


can i use a non-sc 3.8? and use the parts from my motor to make a new motor sc??

let me know!
