2) Chech and make sure the oil pan is not dented to hell and back... The Pickup tube and screen reside low down in the oil pan...
3) What kind of oil filter are you using on that car?

Hi Jr,
1) The car sat 1.5 yrs prior to its crash repair....and yes it was using anitfreeze since it was
fixed which would lead me to think it was using it before the crash also.
2) Oil Pan is perfect and shows no signs of an accident.
3) I can't remember what oil filter was on there when I was under the car last night...
I know it wasn't Fram...and I know it was white....Im not sure what the repair shop used
after the intake/head replacements....
I am going to call the guy I bought the car from today......there is a good chance he just
may want to buy this car back...its already cost him a small fortune and is upside down in
it by now....
I don't want to get rid of her....but...can't afford these trouble either...
I'll keep ya posted...
~Jeff

Otherwise, it may be the start of:
A. bad Oil Pump.
or B. Conn Rod Bearing clearance.
Both are near fatel. I had the later with my 92 SE. The knocking stated only after the oil pressure dropped so low as to set the alarm off (low oil pressure ding) & the engine was starved for oil due to not enough pressure! If you get it fixed now, maybe you can get away with just a Crank Kit & bearings. I needed a whole engine due to the proposed damage to the Conn Rod & possible Block.

Al, was it common for the 3800 and 3300 from 91 - 95 for the 3800, and 89- 93 for the 3300 to have some trouble with the clearances with the bearings in the bottom end... I knoe I have seen several 3300 die an early death due to the bearings in the bottom end, and before 100,000 miles too...

There is also this!
COLD ENGINE TICK/RATTLE AFTER STARTUP (REPL. PISTONS & PINS) #47-61-15 - (07/27/1994)
SUBJECT: COLD ENGINE TICK OR RATTLE AFTER START-UP (REPLACE PISTONS AND PINS)
MODELS: 1990-94 BUICK ELECTRA, LESABRE, REATTA, REGAL, RIVIERA AND PARK AVENUE 1990-94 OLDSMOBILE EIGHTY EIGHT, NINETY EIGHT AND TORONADO 1990-94 PONTIAC BONNEVILLE
1992-94 CHEVROLET LUMINA APV 1992-94 OLDSMOBILE SILHOUETTE 1992-94 PONTIAC TRANS SPORT WITH 3800 ENGINE (VIN L - RPO L27)
CONDITION:
PISTON PIN TICK OR RATTLE MAY BE DESCRIBED BY CUSTOMERS AS A TICKING NOISE THAT BEGINS SHORTLY AFTER COLD START-UP AND GRADUALLY DIMINISHES AS THE ENGINE WARMS UP. IN MOST CASES, THE NOISE IS GONE AFTER FIVE MINUTES. IN SEVERE CASES, THE NOISE MAY NOT DISAPPEAR WHEN THE ENGINE IS HOT.
PISTON PIN NOISE OCCURS IN BOTH PARK AND DRIVE AT IDLE RPM, VARYING IN INTENSITY DEPENDING ON THE NUMBER OF PISTONS INVOLVED. A TICKING SOUND MEANS ONE PISTON IS AFFECTED; A MARBLY RATTLE OR DIESEL-TYPE SOUND MEANS TWO OR MORE PISTONS ARE AFFECTED.
CAUSE:
THE SPECIFICATION FOR PISTON-TO-PIN CLEARANCE IS 0.0004 TO 0.0008 INCH (0.010 TO 0.020MM). STUDIES HAVE SHOWN THAT TRACE LEVELS OF NOISE CAN OCCUR BETWEEN 0.0006 AND 0.0008 INCH (0.015 TO 0.020MM). WHEN THE CLEARANCE IS AT 0.0008 (0.020MM), THE NOISE MAY BECOME AUDIBLE TO THE CUSTOMER.
**NOTE** TESTS HAVE ALSO SHOWN THAT PISTON PIN RATTLE DOES NOT HAVE ANY NEGATIVE EFFECTS ON SHORT TERM OR LONG TERM ENGINE DURABILITY.
CORRECTION:
IF PISTON PIN NOISE IS DETECTED AND THE CUSTOMER DESIRES THE CONDITION TO BE CORRECTED, REPLACE ALL SIX PISTONS AND PINS. THE NEW PISTON SETS HAVE MINIMAL PISTON-TO-PIN CLEARANCES.
SERVICE INFORMATION:
USE THE PROCEDURE OUTLINED IN THE APPROPRIATE SERVICE MANUAL FOR PISTON REPLACEMENT.
**NOTE** WHEN INSTALLING THE NEW PISTON AND PIN ASSEMBLY ONTO THE EXISTING RODS, USE EXTREME CARE TO AVOID DAMAGE TO EITHER THE PIN OR PISTON PIN BORE. IF DAMAGE TO THESE AREAS OCCUR, THE NOISE WILL RETURN BECAUSE THE DAMAGE WILL CAUSE WEAR AND EXCESSIVE CLEARANCE.
PARTS INFORMATION: PISTON ASSEMBLY APPLICATION PART NUMBER ----------- --------------- 1990-92, INCLUDING 1993 BUICK RIVIERA 12537198 1993-94 12537200

my guesses are he will offer to buy the car back from me tomorrow....and I will most likely do so.....
That will leave me with the $2500 again to car shop......NOT FUN...
that don't get ya much....
and I hate to say it ...but another bonnie headache won't be in my future....
this has to be a dependable second car...and I cannot afford to sink money into
repairs..
t...the hell if I know what I will buy.... :?: :?:

I know what **could** be wrong
My oil pressure did the same thing. The car also sat for a long time, then after about 1000km I blew the number 1 cam bearing. The car will run fine, but the digging will start to **** you off.

Out of curiousity, why is everyone automatically pointing at the bottom end? I realize 3800 have a bad record with the bottom end, but it without any knock, and the pressure drop, isn't it conceivible that it may have bad cam bearings, not rods or mains?
