Hello all I have a Toyota Tercel 1.5 L 3EE
4 speed stick..

I just got the thermostat changed to a working one.. and
EVER since I got the car the Valves tap... Some times they do and some times they Dont.....
Motor Temp relly never made a difference.. The tap is on the High pitch side its not a Deep tap...

A person told me to try thinner oil... i use 10-30 Now,, Any Advice..
