Frequently Asked Questions
What's the difference between an in-frame overhaul and a complete rebuild?
An in-frame overhaul involves rebuilding the engine while it remains in the truck — replacing pistons, liners, rings, and bearings without removing the engine block. A complete rebuild involves pulling the engine entirely for a full teardown and reassembly. We’ll recommend the right approach after diagnostics.
How do I know if my engine needs an overhaul?
Common signs include excessive oil consumption, visible blow-by smoke, loss of power, overheating, high coolant usage, and knocking or misfiring. A proper diagnostic will confirm the extent of the issue.
Do you provide a diagnosis before committing to engine work?
Yes. We run a full diagnostic before recommending any major engine repair or rebuild. You’ll know what we found and what it takes to fix it before work begins.
How long does an engine overhaul take?
It depends on the extent of the damage, parts availability, and current shop workload. We’ll give you an honest estimate upfront and keep you updated throughout.
