Coolant Leaks, Head Gasket Issues on Toyota 2.2L Engines

Depending on the production date code of the engine stamped on the front of the cylinder head, two types of head gaskets are used. Use a composite-type gasket (p/n 11115-74081) if engine number is lower than 5985000. Use an MLS (multi-layer steel) gasket (p/n 11115-74120) if the engine number is 5985000 or higher.

It is important to use the correct style head gasket in attempts to seal this type of coolant leakage. The mounting bolt torque for both style gaskets is the same, 36 ft.lbs. plus an additional 90° turn.

In addition to gasket style, caution should be used when ordering replacement cylinder heads and gasket sets because California and Federal part numbers are different.

If the cylinder head is being replaced, it is important to use parts manufactured after 8/4/1997. Composite gasketGasket chart

Many times, the flange diameter of the rod nuts will contact the radius around the nut seat on some rods. Some jobs may not warrant the expense of spot facing the nut seat on the connecting rods. In that case, it can be quicker and more effective to just machine a chamfer on the ARP rod nuts.

Several manufacturers named automation as one of the biggest continuing trends surrounding CNC equipment these days, and it’s clearly a key contributor to a CNC machine’s ability to do more without human interference.

Crankshaft Counterweights

Most engines are internally balanced, meaning all weight adjustment is done on the crankshaft counterweights. However, some stock and modified engines require external balancing due to an increased stroke or larger pistons, and the crankshaft counterweights that would be required to offset the increased inertia simply don’t fit inside the crankcase.
