White smoke, coolant disappearing with no leak on the ground, bubbles in the surge tank, oil that looks like coffee — these are head gasket and cylinder head symptoms, and guessing at them is expensive.
Answering calls day & night across Miami-Dade and Broward. Se habla español.
A failed head gasket and a cracked head share almost every symptom, but they are very different repairs and very different bills. So before anything comes apart we prove which one you have: a block test for combustion gases in the coolant, a cooling-system pressure test, compression and leak-down readings, and a look at what the oil and coolant are actually telling us. Only then do we quote the job. Miami heat and long idle hours make overheating the usual trigger, so we also find out why it overheated — otherwise the new gasket goes the same way.
Block test, pressure test and leak-down before the head comes off, so you pay for the right repair.
Diagnosis and many repairs at your location; machining and pressure-testing handled through our machine shop.

The symptoms overlap, so we test instead of guessing. A block test finds combustion gases in the coolant, a pressure test finds where it is going, and compression or leak-down readings point to the cylinder. Which one it is changes the repair and the price a lot.
We do the full diagnosis at your truck, and on many engines the head can be pulled and replaced there. If the head needs machining, crack-testing or a valve job, it goes to the machine shop and comes back — we tell you that up front, with the timeline.
It depends on the engine and whether the head has to be machined. A straightforward gasket job is usually a matter of days; if the head needs shop work, add the machining time. You get a realistic schedule before we start.
That depends on the engine's mileage, oil pressure and cylinder condition. If the bottom end is tired, a head job just moves the problem — we tell you honestly when a rebuild is the better spend.
