"🛢 DD15 Oil Leak The Real Reason Your Cam Housing Is Leaking ⚠ DD15 cam housing leaks are one of the most common oil issues we seeand theyre often misunderstood. This isnt just a gasket problem. Its a combination of: Heat expansion between aluminum and steel Poor surface prep or leftover sealant Incorrect torque sequence Excess crankcase pressure from restricted CCV filters Wrong oil viscosity or overfilling Vibration over time causing seal breakage 🔧 Fix it right: ✅ Clean all surfaces ✅ Replace the CCV filter regularly ✅ Use correct oil viscosity and fill level ✅ Torque to spec in proper"

"In this clip our techs at TAT Express perform an air-in-fuel test and spot the warning signs: foamy aerated fuela clear indicator that air is entering the fuel system. This might seem small but air in the fuel can cause: ❌ Hard starts ❌ Rough idle ❌ Low power ❌ Injector and pump damage These are common symptoms we see on DD15 D13 and ISX engines. Catch it early with proper diagnosticsnot guesswork. 📍 TAT Express 4140 Langdon Rd Dallas TX 75241 📞 972-225-3017 👉 Stop by or call today.

"🔥🚛 Turbocharger Failure Confirmed PACCAR MX-13 Engine 🚛🔥 Customer Concern: Black Smoke & Low RPM This PACCAR MX13 came in with two major symptoms: ➡ Excessive black smoke ➡ Engine RPMs not climbing as they should After running several diagnostic tests our specialist tech pinpointed the root cause: a failed turbocharger. 🎥 As shown in the video the turbo actuator vanes are stuck meaning the turbo cannot open and regulate airflow into the engine. When the vanes dont move the engine receives very little boost causing: ⚠ Why this causes black smoke: When the turbo doesnt supply enough air"

"💨🔍 Intake Leak Found Cummins X15 Engine Inspection 🔍💨 During inspection on this X15 engine our specialist tech located an intake leak affecting the engines air delivery and overall performance. Even a single leak in the intake system can cause major drivability issues especially under load. 💡 Why intake leaks matter: The intake system must stay completely sealed to ensure the turbocharger delivers the correct amount of boost to the engine. When theres a leak: Boost pressure drops Fuel-to-air ratio becomes unbalanced Power and acceleration suffer Excess soot is produced Regen cycles may"

"💨⚠ Boost Leaks Found on EGR Cooler MP8 Engine Inspection ⚠💨 During a boost leak test on this MP8 engine our specialist tech identified multiple leaks coming from the EGR cooler area. Any leak in the intake/boost system affects the entire engines performance especially when its tied to the EGR system. 💡 Why boost leaks at the EGR cooler matter: Loss of turbo boost pressure = reduced power and sluggish acceleration Incorrect air-to-fuel ratio = excessive smoke or higher fuel consumption Disruption of EGR flow = active EGR system codes Higher exhaust temperatures that can affect turbo and"

"🔍📊 EGR Pressure Sensor Readings Too Low D13 Engine Diagnostic 📊🔍 During diagnostic testing on this D13 engine our specialist tech monitored the EGR pressure sensor readings and as shown in the video the values were below XXX which is far lower than expected during a proper flow test. This indicates that the EGR system is not building the pressure it should. 💡 Possible causes of low EGR pressure readings include: Clogged EGR cooler restricting exhaust flow Faulty or clogged EGR differential pressure sensor hoses Leaking gaskets or exhaust leaks before the sensor EGR valve stuck open or"

"💥💧 DD15 Fuel Line Leak Watch This Diagnostic Trick 🛠🚛 In this clip our tech is diagnosing a fuel line leak on a Detroit DD15. With the engine running he carefully blows air along the outside of the fuel line connection and you can see fuel spray out from the fitting. This is a real-world in-bay technique to confirm fuel line leaks when: 🔧 Engine is running 🔧 Leaks arent visible until pressure is applied 🔧 No fuel shows at idle but still causes rough run or air intrusion He then checks the next line and no leak is present confirming the issue is isolated. 🧠 On a DD15 air in the fuel"

"🔧🚛 EGR & Turbo Actuator Check Paccar MX13 🛠🔥 Our tech is checking for binding by manually moving the actuator arms for the EGR valve and turbocharger on this Paccar MX13. This step helps confirm that components move freely and arent sticking a key part of diagnosing airflow and emissions issues. ✅ 👉 If your truck is losing power throwing fault codes or struggling with aftertreatment performance it could be linked to restricted movement in these systems. A proper check can save you time money and breakdowns on the road. 📍 TAT Express Dallas TX 4140 Langdon Rd Dallas TX 75241 📞"

"💨🔧 Injector Fuel Lines Installed & Torqued to Spec Leak-Free Finish 🔧💨 In this video our specialist tech has completed the installation of all new injector fuel lines and ensured each connection was torqued to factory specifications. After installation the system was pressure-tested no fuel leaks were detected confirming a proper seal and precise installation. 💡 Why proper torque and installation matter: Fuel lines operate under high pressure and even a slightly loose or over-tightened fitting can lead to fuel leaks poor combustion or injector damage. Following exact torque specs"

"Detroit did update the DD15 oil pickup tube O-rings with better material but even with the new design high-mileage engines can still lose pressure. ⚙ After 500600K miles its smart to inspect the O-rings and oil suction manifold for wear or hardening. 💀 A small air leak here can starve the pump and wipe out your bearings fast. 🛠 Anytime the pan or pump is serviced check those seals cheap insurance for a $40000 engine. 🎬 Full breakdown here: 👉 DD15s Hidden Oil Pressure Killer The $XX O-Ring That Destroys Engines https://youtu.be/AntZWzlyKYAsi=ttPqBn8ahev0XRr8 📍 TAT Express Inc Diesel"

"💧⚠ Coolant Reservoir Draining During Acceleration DD15 Engine Diagnosis ⚠💧 During inspection and live testing on this DD15 engine our specialist tech observed that the coolant reservoir was draining rapidly every time the truck accelerated. This behavior is not normal and is a strong indicator that the cooling system is experiencing internal pressure issues. 💡 What this symptom suggests: When coolant drops under load or acceleration it usually means the cooling system is being forced into an over-pressurized state. Even if no visible leaks are present something is pushing coolant out of"

"🛠💧 Air Compressor Bypassed Confirmed Failure on This DD15 Engine 💧🛠 During the diagnostic process on this DD15 engine our specialist tech performed a series of tests to identify the cause of coolant pushing out of the reservoir during acceleration. Initial symptoms included: Coolant level dropping rapidly under load Coolant overflowing with pressure Signs that could indicate combustion gases entering the cooling system To narrow down the root cause the air compressor was bypassed a critical step to verify whether the compressor was introducing air into the coolant system. 🔍 What we found"

"🛢⚠ Fuel Leak Found at High-Pressure Pump Power Stroke Engine Inspection ⚠🛢 During inspection of this Power Stroke engine our specialist tech discovered fuel leaks coming directly from the high-pressure pump. This pump is responsible for supplying precise fuel pressure to the injectors and any leak in this area can quickly turn into a major performance and safety concern. 💡 Why high-pressure pump leaks matter: The high-pressure pump operates under extremely high fuel pressure. Even a small leak can: Reduce fuel pressure and affect engine performance Cause hard starts or long crank times"

"On a DD15 the EGR system recirculates 3040% of exhaust gases back into the intake and that changes everything. Those intake temps jump from normal Series XX levels of 90160 all the way up to 250400. Thats a massive difference in how the engine runs performs and wears. Understanding this helps you diagnose issues faster and avoid unnecessary breakdowns.

"Ever wonder what that small tube on your Volvo D13 or Mack MP8 is actually doing Thats the Venturi Tube the part responsible for measuring EGR flow using a pressure drop so the ECM knows exactly how much exhaust gas is being recirculated. When it clogs or leaks you get bad readings poor performance and derates. Raw clip explains it all.

"🔥🛢 Transmission Oil Cooler (Heater Exchanger) Leak Found Columbia Truck 🛢🔥 During inspection on this Columbia truck our specialist tech found the heater exchanger used for the transmission oil cooler leaking. This component helps regulate transmission temperature by transferring heat between fluids and when it leaks it can quickly turn into a major reliability issue. 💡 Why this matters: The transmission oil cooler keeps fluid at the correct operating temperature. A leak can cause fluid loss overheating and poor shifting putting internal transmission components at risk. ⚙ Common causes of"
