Why does oil come out right exhaust pipe ? - 1985 Oldsmobile Delta 88

1. Raise the front of the vehicle and support it safely using jackstands. Remove the plug and drain the engine oil from the pan and crankcase.
2. Disconnect the fasteners from the exhaust manifold flange and the pipe rear flange, then remove the front exhaust pipe and gaskets from the vehicle.
3. Remove the engine stiffening bracket and the flywheel cover.
4. Remove the right wheel and splash shield, then loosen the 4 front motor mount bolts. Back the bolts out about 1 / 2 in. (12mm).
5. Remove all the oil pan bolts. For vehicles with a manual transaxle, an 8mm flex socket may be used to access the rear oil pan bolts located next to the flywheel.
6. Using SA9123E, or an equivalent RTV cutter tool, separate the oil pan from the engine. Drive the tool around the pan to shear the RTV seam, then tap the pan sideways with a rubber mallet to loosen.
7. Pry the engine mount away from the engine as necessary and remove the oil pan. Be careful not to damage or score component surfaces when prying.

To install:

1. Carefully clean the gasket mating surfaces with a scraper and solvent.
2. Apply a 0.16 in. (4mm) bead of RTV sealer to the pan flange. Make sure the RTV is applied to the inner side of the flange from the bolt holes as shown.
3. Install the oil pan within 3 minutes of RTV application and tighten the bolts to 80 inch lbs. (9 Nm).
4. Tighten the front mount bolts to 37 ft. lbs. (50 Nm).
5. Install the right splash shield and wheel.
6. Install the engine stiffening bracket and the flywheel cover.
7. Install the exhaust pipe. Tighten the pipe to manifold nuts in a crosswise pattern to 23 ft. lbs. (31 Nm) and the pipe to converter bolts to 33 ft. lbs. (45 Nm).
8. Remove the jackstands and carefully lower the vehicle, then fill the engine crankcase with clean engine oil immediately in order to prevent an attempt to start the engine without oil.
9. Start the engine and check for leaks.

1. Disconnect battery negative cable.
2. Remove air cleaner.
3. Remove upper fail shroud (V8)
4. Raise vehicle and drain oil pan.
5. Disconnect A.I.R. hose at converter pipe (V8)
6. Disconnect A.I.R. pipe at exhaust manifold (V8)
7. Remove exhaust crossover pipe at manifold and converter.
8. Remove starter.
9. Remove flywheel cover.
10. Disconnect transmission oil cooler lines at oil pan.
11. Remove engine mount 'through' bolts on V8. Loosen right bolt and remove left on V6.
12. Remove oil pan bolts and lower oil pan. Check that forward crankshaft throw and/or counter balance weight are not extending downward so to block oil pan removal. Turn crankshaft, necessary, to put throw on horizontal plane.
13. Raise engine.
14. Remove oil pan.

Installation

1. Clean sealing surfaces on cylinder case and pan.
2. Check oil pan gasket for damage; replace if necessary.
3. Apply a small amount of 1052751 or equivalent to front and rear corners of oil pan.

NOTICE: Only a small amount of sealant is required. Excessive amounts of sealant may cause a problem with proper sealing of oil pan.

1. Install retaining bolts and torque to 9 N.m (80 lb. in.).
2. Raise engine, if necessary.
3. Lower engine, install mount 'through' bolts and torque to 50 lb. ft. (65 N.m).
4. Install torque converter cover.
5. Install starter.
6. Install exhaust crossover pipe at manifold and converter.
7. Lower vehicle.
8. Install fan shroud.
9. Install air cleaner.
10. Fill crankcase with oil.
11. Connect battery negative cable, start engine and check for leaks.

Your buring oil. Bring vehicle to a repair shop this way they can determine whetherits a pcvor transmission vacuum switch thats causing it or is it engine mechanical.

Changing the oil pan gasket on a GMC Yukon XL is realtively simple, but does require removal of the exhaust pipe. You will need a new oil pan gasket and a new exhaust pipe flange gasket.
Put the car on ramps or jacks to access the undercarriage.
Remove the exhaust pipe by removing the 3 nuts holding the exhaust pipe flange to the exhaust manifold. These nuts often rust and prior application of penetrating oil may be required to remove them without damage. Once the pipe is unbolted, work the exhaust system loose from the hanging brackets. In most cases the entire system does not have to be removed since there is enough room to remove the pan with only the front hangers removed.
Drain the oil from the engine
Remove the 10 mm bolts holding the pan to the block.
Remove the old gasket material and scrape any remaining gasket from the block and pan.
Install the new gasket. Forma-Gasket or a similar product may be used in small quantities to "glue" the new gasket in place and prevent shifting while the pan is reattached to the block.
Reinsall the 10 mm bolts in a cross pattern to ensure the gasket is compressed evenly. Do not overtighten the bolts.
Replace the pipe to flange gasket between the exhaust pipe and the exhaust manifold with a new part.
Reattach the exhuast pipe to the hangers.
Install the 3 bolts connecting the pipe flange to the exhaust manifold.
Fill the engine with oil.

Ok, check the head gaskets for damage and the valve cover gaskets as well. replace any gaskets that are visibly worn. check the oil pressure switch as well. this is a leak spot.

Leaking exhaust pipes and deflated radiator can be the result of this. Better start with the radiator first and check if its deflated. Also make sure the pipes are tightly mounted and double check any leak.
