Engine noise


#1

1985 Toyota 4 runner. Has a loud tapping noise in engine. A friend said we could run hydralic oil at an ideal and clean the noise up. Another friend said you had to wedge the tappet and do alot of work to fix this.The car has 205000. miles but the engine is suppose to be an 87 with ? miles. Fix it, run it,shoot it ? Thanks MLB
