What is Acceptable Oil Consumption in Diesel Engines?
All engines will consume some amount of oil, and as an engine ages and wears we generally accept increases in consumption, but in low mileage or low hour engines oil consumption can be frustrating. Letting an engine with truly high oil consumption go unchecked can result in shortened engine life and/or engine failures. External
Additive Packages Play Key Role in Keeping an Engine Clean
Premium quality motor oilwill maintain its effectiveness over the life of the oil drain,allowing it to help in keeping the engine clean. Additivepackages are added to motor oil and play a key role in helping to keepan engine clean and protected from varnish and sludge, as well as wearfrom heat and acids. Additives can consist

Bedplates Have Presence In Today
One of the technologies that has been implemented for many of theengines today is the configuration of the block. Many of today’sengines are using “bedplates” (see Figure 1).The block is split at the main bearings or the crankshaft centerline sothere are two distinct pieces to the block; an upper part that housesthe cylinders and the
Toyota 2VZ-FE, 3VZ-E and 5s-FE Connecting Rod Bolt Tightening Procedure
The bolt has a tendency to rotate slightly inside the rod when performing the final tightening. If not compensated for, this may result in a lower final torque than specified. To achievethe correct torque use the following procedure. This procedure will ensure that a full 90° degrees of nut rotation relative to the bolt is

Tests: 1. Check the actual temperature of the radiator and compare it to the temperature of the cylinder head. 2.If the radiator remains significantly cooler than the cylinder head, orif no coolant flow is evident in the cooling system, check the waterpump impeller for damage, missing fins or spinning on the water pumpshaft. 3.
