Toyota L Engine-Weak Power Resolved

Too weak, and overheating after it has been overhauled. It ‘s unbelievable. When your engine is pretty working when it was not yet overhauled you will wonder why and you may blame the mechanic for such condition.  It should work efficiently because it was newly overhauled.

This newly overhauled Toyota L Engine displayed a weak power when it was road tested. Whatever you do with the timing either you advance it or retard it, it does not make any change in the power. The engine nearly cannot pull its body on an elevated road.

The technician believes everything is in its proper place and the issue has nothing to do with the overhauling. He rather recommended that the injection pump is calibrated.


What is Calibration?

Calibration includes replacement of O-rings, oil seals, cleaning and testing with a machine if the injection pump functions accurately or not.

This is an additional expense for it is not easy when you don’t have the budget. The cost is two thousand seven hundred pesos (P2,700.00).

The injection pump was brought to the Calibration Center, disassembled and cleaned.

And then assembled and put to the test machine.  Now, we don’t know what would have been the defect of the injection pump since it was disassembled without the test first.  If it would have been tested before it was disassembled maybe we have known if it is clogged or any of the adjusting screws have been meddled in by a mechanic in the previous years.

The purpose of the calibration now is all specks of dirt which have been sucked from the fuel are to be removed and to return the function of all parts in the normal way.

Calibration

All tests have been done and the injection pump was hopefully in good condition. Back to the engine and the pump was attached.  After everything had been placed, the engine was started.

Noticeably, the engine is now quieter, less smoke and the engine’s power was restored.  It was a grueling task but it’s worthy to have been done. No issue on the overhauling but it’s outside the engine, it’s the fuel injection pump.
