I have an 87 22r pickup 2wd. The other day when I got on the gas it started knocking at a higher rpm so a friends suggested adjusting the valves so we did. After that it's been a constant knock with a lack of power. The knock kinda makes it sound like a Diesel engine. Any ideas?

 

What specs did you use when you adjusted the valves?

 

i was half awake once adjusting valves and used thousands of an inch instead of metric thousands..

 

.008 on the intake and .012 on the exhaust

 

Compression test?
It could be a rod knock. Does it sound like its detonating from the timing being off / bad gas or a metal on metal knock?

 

i have a 1986 22r and my motor knocks as well . i am also trying to figure out what it is i checked compression and i have 150 in all 4 cylinders witch is not bad . also adjusted the timing it was off by 5 degrees . also did the valves and it continues to knock . any ideas???
