jaywede Posted June 1, 2004 Share Posted June 1, 2004 I have a 1987 gl wagon, 5 speed, carb, no turbo, and it has developed a loud knocking noise. It sounds like the lifters and the prev. owner said it can do this time to time. I changed the oil, put in 10w-40, and It still knocks. Does anyone have any ideas about quick fixing this prob. Your help is greatly appreciated. Thanks, Jay Link to comment Share on other sites More sharing options...

XT Fan Posted June 2, 2004 Share Posted June 2, 2004 I've only heard lifters make a ticking sound, loud knocking sounds like something else? Moving, sitting still? Does sound increase with RPM'S? In gear, out of gear? Link to comment Share on other sites More sharing options...
lagwagon Posted June 2, 2004 Share Posted June 2, 2004 I bought some of that Sea Foam yesterday at NAPA. It worked for me. Link to comment Share on other sites More sharing options...
Partsman Posted June 2, 2004 Share Posted June 2, 2004 Need to know - is it really "knocking?" Or is it "ticking" like half the EA82's on the road? If it's the latter, do a search for "lifter noise" or "ticking" and you will come up with a veritable plethora of Info. Link to comment Share on other sites More sharing options...
