After installing on the stand and starting the engine, check the following:
- there are no leaks of coolant or fuel between mating parts, from pipe connections and through gaskets;
- oil pressure and is there any oil leakage through the gaskets;
- idle speed;
- are there any extraneous knocks?.
If any unusual knocking or malfunctions are detected, stop the engine, eliminate them, and then continue testing.
If oil leaks through the gasket between the cover and the cylinder head or through the gaskets between the engine oil pan, cylinder block and covers, tighten the mounting bolts to the recommended torque. If the oil leak does not stop, check that the gaskets are installed correctly and replace them if necessary.
Since the engine has not yet been run in after repair and the friction of the working surfaces of the new parts provides significant resistance to rotation, a certain running-in period is required.
This applies in particular to those engines on which the pistons, connecting rod and main bearing liners have been replaced, the crankshaft journals have been reground, and the cylinders have been honed.
Therefore, during the running-in of the repaired engine, do not subject it to maximum loads. The engine running-in should continue on the vehicle, observing the driving speeds recommended for the vehicle running-in period.
