⚠️ Toyota V35A-FTS Engine Common Problems

1. 🧽 Carbon Deposit on Intake Valves

Like any direct injection engine, the V35A-FTS suffers from carbon deposit on the intake valves. This can lead to:

  • Reduced airflow
  • Loss of fuel efficiency
  • Engine misfire
  • Rough idle

Why it happens:
Since fuel never passes through the intake valves in direct injection engines, vapors from oil that is within the PCV system can accumulate and be carbon deposits.
We clean, inspect, and test our engines before sale. Valley cleaning or walnut blasting optionally can be ordered before install.

2. 🔄 Turbocharger Wearing and Failure

Twin-turbo design is designed to deliver immediate torque and silky power. Turbochargers burn and wear out over time due to:

  • Starvation or oil contamination
  • Too much exhaust heat
  • Inadequate quality oil or no oil change

Symptoms:

  • Whining noise from the turbo
  • Power loss
  • Check engine light on
  • Exhaust smoke

Good news:
When you buy a rebuilt or used V35A-FTS engine from us, the turbo system is inspected for performance and leaks. Bad units are replaced.

3. ⛓️ Timing Chain Tensioner Issues

The V35A-FTS utilizes a timing chain, which will run beautifully during the life of the engine—but tensioner or guide failure can result in:

  • Rattling sound on cold start
  • Misalignment of timing
  • Potential engine damage if not corrected

Why it occurs:

  • Low oil pressure
  • Cheaper or the wrong oil
  • Oil overdue service

Our engines:
Treated to timing system check and replace as needed before shipping. We guarantee your new V35A engine to be efficient and quiet.

4. 🛢️ Turbo Oil Line or Valve Cover Leaks

Hot spot leaks are normal, and the V35A-FTS has also seen cases of:

  • Leaks in turbo oil feed or return lines
  • Valve cover gasket leak
  • Front main seal wear

Causes:

  • Low oil level
  • Burnt oil odor
  • Dirty engine bay

Our solution:
We pressure test and inspect all used and remanufactured V35A-FTS engines. Gasket and seal leaks are replaced in our quality control.

5. 🔋 Hybrid-Specific Issues (LS500h & Tundra Hybrid)
