FAQ

Q: What is the exact outer diameter of this liner, and how critical is it for fitment?
A: The outer diameter is precisely 203mm. This is a critical dimension for press-fit installation into the engine block. If your block bore is worn beyond specification, you may need a block rebore or an oversized liner. We recommend measuring your block bore before ordering if you suspect wear.

Q: Can this liner be installed without special tools?
A: While a basic press can be used, we strongly recommend using a hydraulic press with a proper liner guide tool to prevent the liner from cocking or cracking during installation. Always lubricate the liner’s outer surface with clean engine oil before pressing.

Q: How should I prepare the engine block before installation?
A: The block bore must be perfectly clean, dry, and free of rust, scale, or old sealant. Check for any raised edges or burrs at the bottom of the bore. For dry liners like this, no sealant is required on the outer wall, but ensure the counterbore depth is uniform to avoid liner distortion after torquing the cylinder head.
