98 Jeep wrangler tj 4.0 oil pan bolt pattern or layout. An torch specs

SOURCE: Need torque specs for oil pan gasket

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

SOURCE: 98 jeep tj 2.5 eng noisey lifter can it be ajusted

Lifters on your engine are non-adjustable. If noise is not loud or is intermittent, sometimes just changing oil and using an additive like marvel oil will clean it up.If noise persists, check pivot contact points on "bridge" that connects each pair of rocker arms together for wear.Replace if worn. disable the ignition system and have someone crank engine over. Observe that all rockers are going up and down the same distance. The ones to check are the ones that are not. If all is ok there, you must go deeper into engine and check lifters for end wear. If you find wear, lifter and camshaft must be replaced Sometimes if the ends are still in good condition, the lifter itself may have an internal problem.If that is the case, replace the lifter.
Before you begin, check oil pressure. A pressure of 15lbs or less is not acceptable.(warmed up, at idle) Pressure must be substantially higher both cold and hot. I recommend at least 30psi at idle hot, 40psi while driving. Lower pressures indicate serious wear on internal bearing surfaces. Replacing the oil pump may temporarily hide this problem but will not cure it!!!
Good luck

4.0L Engine To Remove:

1. Disconnect negative battery cable.
2. Lift the vehicle.
3. Drain the engine oil.
4. Remove or disconnect the following:
   • Exhaust pipe from exhaust manifold.
   • Exhaust hanger at the catalytic converter and lower the pipe.
   • Starter motor.
   • Flywheel/torque converter housing access cover.
   • Oil level sensor (if equipped).
5. Place a pole jack under vibration dampener with a piece of wood between dampener and jack.
6. Remove or disconnect the following:
   • Engine mount through bolts and raise engine for clearance to remove pan.
   • Transmission cooler lines (if equipped).
   • Oxygen sensor harness from oil pan mounting studs.
   • Oil pan bolts and studs.
   • Oil pan and gasket.

1. Clean the gasket mating surfaces.
2. Apply Mopar® Silicone Adhesive Sealant or equivalent onto the cylinder block in four location as shown.

1. Attach the pan gasket to the oil pan with Hi-tack or equivalent (2003-2005 vheicles).
2. Use 1 ½ x ¼ inch bolts to fabricate alignment dowels. Cut off the head of the bolts and cut a slot into the top of the dowels (2006 vehicles).

1. Install two dowels into the timing case cover (2006 vehicles).
2. Install two dowels into the cylinder block (2006 vehicles).
3. Place the gasket over the dowels and onto the cylinder block and timing case cover (2006 vehicles).
4. Position the oil pan.
5. Install the 1/4 inch oil pan bolts. Tighten to 84 in-lb (9.5 Nm).
6. Install the 5/16 inch oil pan bolts. Tighten to 132 in-lb (15 Nm).
7. Remove the dowels.
8. Install the remaining 1/4 inch oil pan bolts. Tighten to 84 in-lb (9.5 Nm) (2006 vehicles).
9. Lower the engine onto the engine mounts.
10. Install the through bolts and tighten the nuts.
11. Remove jack stand and remove the piece of wood.
12. Install the flywheel and torque converter access cover.
13. Install starter motor.
14. Connect the exhaust pipe to the hanger and to exhaust manifold.
15. Install the transmission oil cooling lines (if equipped).
16. Install the oxygen sensor wiring supports to the oil pan mounting studs.
17. Install the drain plug into the oil pan. Tighten to 25 ft-lb (34 Nm).
18. Lower the vehicle.
19. Connect negative battery cable.
20. Fill the oil pan with oil. WARNING
    Use extreme caution when the engine is operating. Do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing.
    
21. Start the engine and inspect for leaks.
