I have a 2001 cadilac deville that has a wicked knock in the engine. it is a rod knock (from the sound) so i figure my options are to change the engine, or change the rod ect. I wanna know if the engine...


Thats going to be a tricky pull. you can actually do BOTH methods fro pulling that motor. Which ever is easier for you would be better.

As far as the rod knock. Rod knock simply means that the rod bearing has spun and is no longer a smooth surface. potentially, you could pull the motor and replace just that rod and bearing if the crankshaft was unaffected. the majority of the time, more work needs to be done. I think in this case, it may be cheaper to remove the motor and replace the crank and bearings. A replacement used motor will probably run about 1k if you can find one at a yard.

Hchanging rod bearings


Are you referring to connecting rod bearings? If so, I hope you're tooled up and VERY mechanically inclined. If that's the case, you'll want to pull the engine, mount it on an engine stand, remove the bottom components (oil pan, oil pump and any other components that would interfere with a complete and open access to the crankshaft). It is possible to change the rod bearings without removing the top of the engine (intake manifold and carb, valve cover, rocker arm, camshaft, valves, lifters and heads), but I wouldn't recommend you try unless you're a real motorhead. In fact, I wouldn't recommend that you even attempt any of this unless you're very experienced at auto mechanics. Of course, if you're NOT talking about connecting rod bearings, you can disregard everything I've said so far, and elaborate on what you actually want to do.

Replacing crankshaft pulley/balancer assy procedure. 1994 Merc Topaz 2.3 4cyl.


Crankshaft and Main Bearings REMOVAL & INSTALLATION NOTE: When draining coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your and and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used. 2.3L Engine
  1. Disconnect the negative battery cable.
  2. Drain the cooling system and engine crankcase.
  3. Remove the engine from the vehicle.
  4. Remove the crankshaft front pulley, front cover, timing chain and sprockets, cylinder head, oil pan, oil pump and intermediate driveshaft.
  5. Remove the rear oil seal cover bolts and remove the cover.
  6. Remove the piston assemblies. NOTE: Mark the connecting rods and bearing caps so they can be installed in the proper cylinders.
  7. Remove the main bearing caps and bearing.
  8. Carefully lift the crankshaft out of the crankcase, so No. 3 thrust bearing surfaces are not damaged.
  9. Remove the main bearing inserts from the engine block and bearing caps. NOTE: For cleaning purposes, the oil gallery and coolant drain plugs can be removed. To install:
  10. Wash the cylinder block thoroughly to remove all foreign material and dry before assembling other components. Check to ensure all oil holes are fully open and clean. Check to ensure the bearing inserts and bearing bores are clean. Clean the mating surfaces of the crankcase and each main bearing cap.
  11. Install the main bearings in the cylinder block. Note that the center front bearing is a thrust bearing and the front upper bearing has a small "V'' notch on the parting line face.
  12. Lubricate the bearings with clean engine oil.
  13. Carefully lower the crankshaft into place. Be careful not to damage the bearing surfaces.
  14. Check the clearance of each main bearing as outlined in this section.
  15. After the bearing has been fitted, apply a light coat of engine oil to the journal and bearings. Install the bearing cap in their original locations . (refer to numbers on caps). The caps must be installed with the arrows pointing to ward the front of the engine. Oil the bolts and tighten to specifications. Repeat the procedure for the remaining bearings. NOTE: Turn the crankshaft to check for turning torque. The turning torque should not exceed 4.5 ft. lbs. (6 Nm).
  16. Install the pistons and connecting rod caps. Check clearance of each bearing, as out lined in this section.
  17. After the connecting rod bearings have been fitted, apply a light coat of engine oil to the journal and bearings.
  18. Turn the crankshaft throw to the bottom of its stroke. Pull the piston all the way down until the rod bearing seats on the crankshaft journal. NOTE: Guide the rod to prevent crankshaft journal and oil cooling jet damage.
  19. Install the connecting rod cap. Align the marks on the rods with the marks on the cap, and tighten the nut.
  20. After the piston and connecting rod assemblies have been installed, check the side clearance between the connecting rods on each connecting rod crankshaft journal.
  21. Install the rear crankshaft seal and cover. Tighten the bolts to 5–7 ft. lbs. (7–10 Nm).
  22. Installation of the remaining components is in the reverse order of removal.

Changing rod bearings


Yes you will have to raise engine to pull pan, but more importantly is why do you need to change rod bearings? If they need replacing you will probably have to change the mains as well as rings and so on. If you have run it knocking, you could have damaged the crankshaft and new bearings won't stay. Suggest you check a little deeper before going to all this expense.
