Guessing is the most expensive way to fix a car. Before you throw parts and money at a problem, or hand over cash for a used car with an unknown history, it pays to actually know what is going on inside the engine. We run proper diagnostics with real tools and real data, so the decisions you make next are based on evidence rather than a hunch, a mate's opinion or a hopeful gut feeling.
Compression And Leak-Down
A compression test tells you whether each cylinder is sealing, and a leak-down test tells you where the pressure is escaping when it is not. Together they paint an honest picture of ring, valve and head gasket health without pulling the engine apart. We test every cylinder, record the numbers and interpret them properly, so a tired cylinder shows up as worn rings, a leaking valve or a gasket giving up into the cooling system. That knowledge turns a vague misfire or a puff of smoke into a specific, costed job, and stops you rebuilding half an engine that never needed touching.
Datalogging
Modern engines leave a trail, and datalogging reads it. We log air-fuel ratio, knock, boost, sensor readings and fault codes while the car runs and under load, catching the intermittent gremlins that never show up sitting in the driveway. A lean spot at high rpm, knock creeping in under boost, a lazy sensor or a boost leak all reveal themselves in the data. For a modified car this is the difference between chasing a ghost for months and pinpointing the fault in an afternoon, and it is the same information a good tuner needs before touching a single map.
Pre-Purchase Inspections
That bargain project car can hide a cracked block, a dodgy swap, hack wiring or a tune that will kill it in a month. Before you buy, we go over the car with the same tools we use on our own builds, checking compression and leak-down, scanning for faults, inspecting the mechanicals and reading how it has been treated. You get a clear, honest report on what it really is and what it will cost to sort, so you can negotiate hard, walk away, or buy with confidence instead of inheriting someone else's expensive mistake.
Straight Answers
The point of a health check is a clear plan, not a mystery invoice. We walk you through what we found in plain language, show you the numbers and evidence, and lay out what needs doing now, what can wait, and what is genuinely fine to leave alone. That means you decide what to spend and when, based on facts rather than being talked into work you do not need. Whether the car is your daily, your project or one you are thinking of buying, you leave knowing exactly where it stands. Honest diagnostics up front are always cheaper than throwing parts at a problem and hoping.
Book a health check or pre-purchase inspection and make your next move with facts instead of hope.
