Engine Block Cleaning and Inspection

Note: All remanufactured cylinder blocks are steel stamped on both sides of the fuel pressure pump boss. The stamp indicates whether the cylinder is standard or over-bored, and if the deck is standard or has been milled.









Note: If the block has no stampings, the block has a standard bore and deck.

1. Inspect the block for stampings (1) indicating cylinder overbore or a milled deck.




2. Remove the engine block heater.
3. Remove the O-ring from the block heater and discard.




4. Remove the oil gallery plugs.




5. Remove the left engine mount bolts.
6. Remove the left engine mount.




7. Remove the right engine mount bolts.
8. Remove the right engine mount.
9. Clean the sealing material from the gasket mating surfaces of the block.
10. Clean the block in cleaning solvent.
11. Flush the engine block with clean water or steam.
12. Clean the oil passages.





Note: Cylinder wall spotting (1) is from the induction hardening process of the top 1/3 of the cylinder wall. This is normal.

13. Clean the cylinder bores.
14. Inspect the block for cracks. Use the Magnaflux Spot check dye method, or the equivalent.

* Inspect the cylinder walls.
* Inspect the coolant jackets.
* Inspect the crankshaft bearing webs.




15. Inspect the crankshaft bearing bores and caps. The crankshaft bearing bore inside diameters should be round and uniform at all of the bearing supports.
16. Inspect the area where the crankshaft bearing inserts contact the crankshaft bearing bore. This area must be free of burrs and scratches.
17. Inspect the engine mount bosses.
18. Inspect the cylinder head gasket mating surfaces for pitting.




19. Inspect the engine block to cylinder head gasket surface area for warping. Use a straight edge and feeler gauge. Replace the block if it is warped more than 0.15 mm (0.006 in) longitudinally or more than 0.08 mm (0.003 in) transversely.
20. Apply sealer to the oil gallery plugs.





Caution: Refer to Fastener Caution (Fastener Caution).

21. Install the oil gallery plugs and tighten to 53 Nm (39 lb ft).




22. Install the left engine block coolant plugs and tighten to 18 Nm (13 lb ft).




23. Install the right engine block coolant plugs and tighten to 18 Nm (13 lb ft).




24. Install the left engine mount and engine mount bolts. Tighten the engine mount bolts to 58 Nm (43 lb ft).




25. Install the right engine mount and engine mount bolts. Tighten the right engine mount bolts to 58 Nm (43 lb ft).




26. Install a new O-ring to the block heater.
27. Lubricate the O-ring with engine coolant.
28. Install the engine block heater.
