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..

 

toss in a bottle of lucus heavy duty oil stabilizer and see if that changes any thing.

other than that, i'd want to know what oil pressure was to see if there was a problem there.

oh, and fyi, there is an toyota tech section.

 

Maybe a little seafoam in the oil before an oil change may help too. Sounds like you have a clogged hydralic lifter if they even have hydralic in them.

 

The toyota tech area is really a dust field... I waited a week and really no postings back..
The lucus heavy duty oil stabilizer Ill try that sounds pretty easy thing to try I am almost do for a oil change.

My uncle has a feeder gauge and Im going to start looking online for the Specs.

 

Transmission fluid works great to flush out the engine. Drain about a quart of the oil out and add a quart of transmission fluid in it. All the detergents in the Transmission fluid should help. You could also try Seafoam, Marvel mystery oil, or Engine Lube or whatever it's called. It comes in a soda can looking bottle. It's silver in color and the logo is a blue diamond IIRC. Run it for a day or so then drain the oil and add a synthetic blend. I would run the synthetic blend after you flush out the engine.


Edit: This is my opinion and solely my opinion. You can try it if you want or try something else. Always remember to do research before you try anything.

 

I've tried ATF aswell and it should help clean out the oil galleries.
