How to Adjust Toyota L Valve Clearance

How to adjust Toyota L valve clearance is easy to do. This is how you will do it.

  • Be sure the clutch is in a neutral position.
  • Remove the cylinder head cover.
  • Turn the crankshaft counterclockwise to the top dead center

A video below is prepared to illustrate how it is done.

Valve Clearance adjustment for Toyota L set to .152mm (.006 inches) for intake and .254mm (.010 inches) for exhaust. I drove this car to test for about 100 kilometers and it’s pretty good in its performance. I did not see the temperature has something alarming.    It’s cool.  This is the most noiseless valve adjustment.  But if you want to hear a little bit noise you can set it on 178mm (.007 inches) for intake and .279mm (.011 inches) for exhaust.

This old car is still working properly.  According to Wikipedia,  It is the first diesel engine from Toyota to use a rubber timing belt in conjunction with a SOHC head.

Engines like 2L-II and 2L-T are still in production to the present day. Vehicles with the diesel engine were exclusive to Toyota Japan dealership locations called Toyota Diesel Store locations until the sales channel was disbanded in 1988.

So here I posted this as a product of my discovery.  A discovery not based on theory only but from direct experience to help others who own the same model and will be able to guide others with the same principle that can be applied to their own cars.
