WHAT WE SEE MOST

Common gas engine problems.

The issues that bring gas trucks to us most often, ranked by how often they fail and what they cost.

  • Top

    Ford 3.5L / 2.7L EcoBoost

    Timing-chain stretch and cam-phaser rattle on cold start, plus intercooler condensation misfires. We check cam/crank correlation before quoting a timing job.

    Get it checked →
  • Top

    Ford 5.4L 3-valve Triton

    Cam phasers, timing chains and spark plugs that break off in the head. We use the right extraction tools so a plug job doesn’t become a head job.

    Get it checked →
  • High

    Ford 6.8L V10 & 7.3L Godzilla

    V10 plug blow-outs and exhaust manifold leaks on older trucks; the 7.3L is tough but needs proper oil and cooling care when towing.

    Get it checked →
  • Top

    GM 5.3L / 6.2L AFM & DFM lifters

    Collapsed lifters cause ticking, misfires and wiped cams. We diagnose properly and repair with the right lifter and cam parts.

    Get it checked →
  • High

    GM Vortec 4.8 / 5.3 / 6.0

    Oil consumption, intake gaskets and fuel pumps on high-mileage Vortec V8s. Still some of the best gas truck engines to keep running.

    Get it checked →
  • Top

    Ram 5.7L & 6.4L HEMI

    Lifter and cam wear (the “HEMI tick”) and broken exhaust manifold bolts. Both are fixable on site when caught early.

    Get it checked →
  • Medium

    Ram 3.6L Pentastar

    Rocker arm and lifter ticks on earlier engines, plus oil cooler housing leaks.

    Get it checked →
  • High

    Toyota 3.4L twin-turbo & 4.7L / 5.7L V8

    2022–2024 Tundra 3.4L engines have an open recall for machining debris; older 4.7L needs timing-belt service and 5.7L air-injection pumps fail. We check recalls by VIN.

    Get it checked →
  • Medium

    Nissan VK56 & VQ40

    Titan 5.6L exhaust manifold cracks (ticking when cold) and early Frontier 4.0L timing-chain guide whine.

    Get it checked →
  • Medium

    Gas cooling & transmissions

    Tucson heat is hard on radiators, water pumps and 6- to 10-speed automatics. Fluid and cooling service matter as much as on a diesel.

QUESTIONS

Gas truck FAQ.

Do you work on gas trucks, or only diesels?

Both. Gas pickups, vans and heavy-duty gas trucks get the same mobile service, tools and written estimates as our diesel work.

Is the labor rate different for gas?

No. Rates follow your truck’s weight class: $149/hr Class 1, $198/hr Class 2–6, $298/hr Class 7–8. See rates.

My engine isn’t listed. Can you still help?

Probably. The directory covers the main families from 1990 to 2026. Send the year, make, model and VIN and we’ll confirm.

How often should spark plugs be changed?

Most modern truck engines call for plugs around 60,000–100,000 miles, sooner for turbo engines that tow. Your owner’s manual and VIN-specific schedule are the final word; we follow them.

READY WHEN YOU ARE

Gas or diesel, we come to you.

Tell us the year, make, model and what it’s doing. We’ll bring the right parts and tools.
