Engine Check

Technical Know-How

Correct installation is the key to ensuring your repaired/rebuild/ new units doesn't give problems in the future.

First things first, why did the original unit unit fail?  Did you know that over 90% of failures are caused due to outside influence? This can be oil contamination, oil starvation, foreign object damage, as well as fuel contamination , fuel delay or starvation.  Before fitting a repaired/rebuild/ new unit, you MUST find the cause of the original failure and correct it before fitting the repaired/rebuild/ new unit.
