Failure to remove oil contamination will result in poor thread‑locking compound adhesion. Prior to assembling the powerhead, all threaded holes on the cylinder head and cylinder block must be cleared of thread‑locking compound dust. Use compressed air to clear thread‑locking compound dust. Wash the cylinder block and crankcase cover with hot soapy water to remove debris and honing compound. Dry the cylinder block with compressed air. Failure to thoroughly clean the cylinder block of honing compound and/or debris will result in premature engine failure.
