Rebuild Assessment

Rebuild Assessment

Compression, leak-down, oil analysis and blow-by checks tell you whether a rebuild, a top-end job or a replacement makes the most sense.

In-Frame Overhaul

In-Frame Overhaul

Liners, pistons, rings, rod and main bearings replaced with the engine in the machine, which cuts downtime and cost.

Out-of-Frame Rebuild

Out-of-Frame Rebuild

Complete teardown, machine-shop work, reassembly and installation for engines that need a full overhaul.

Cylinder Head Rebuilds

Cylinder Head Rebuilds

Head removal, pressure testing, valve and seat work and reinstallation with new gaskets and correct torque procedures.

Crankshaft & Bearing Work
