- Hi. My 1986 Toyota Corolla with only 50,000 Km
- requires regular valve clearance adjustments to
- silence a valve ticking noise that develops every
- few months. The local Toyota dealer says I
- need a new rocker shaft assembly installed for a
- total of about $400.00. Another dealer says
- it might be one of the following:
-
- 1. Rocker shaft arm worn. No need to replace.
- No need to worry about long term damage to
- engine if left to tick. Surprising since
- car only has 50,000 km
-
- 2. Valve stem off center where it meets the
- rocker shaft arm. Should be fixed.
-
- 3. Carbon build-up near or under valve. Try
- cleaning out the carbon by slowly pouring
- about 1/2 cup of transmission fluid into
- carburator. Do this outside as there will
- be lots of smoke.
-
- The carbon build-up theory is possible since the
- car is city-driven only and was once diagnosed with
- badly carbon-fouled spark plugs due to a clogged
- air filter.
-
- I am looking for opinions from everyone out there!
- Has anyone been through anything similar to this
- with their Toyota (it's an 8-valve 1600cc engine)?
- Is pouring transmission fluid into the carburator
- a good carbon-cleaning trick or a waste of time and
- possibly damaging?
-
- Help!
