our engine installation process

We take delight in undertaking a thorough inspection procedure to ensure that each engine delivered by Tonmax Engines meets our high-quality requirements. 

A compression test shows the state of the engine’s valve, its valve seats and piston rings. Compression should be over 100 psi per cylinder in healthy engines, with no more than 10% variance between the highest and lowest readings. 


Our expert specialists carry out a compression test on each cylinder as well as a visual inspection to ensure that the engine you get is fit for shipping.
