I have a 86 GN and when i first start the engine it knocks from the engine bay and then after awhile i guess after it warms up the knocking stops. Any suggestions to what might be causeing this would be appreciated.
Thanks

Don't mean to scare you but it could be piston slap. I just had a piston explode(literally)in a 1991 dodge colt vista and the car did the same thing would knock when cold and quit after it warmed up. The piston is totally gone. Just my 2 cents, I maybe wrong. And I hope I am.
Is a knock or loud ticking. The cam sensors on some engines will make a loud and heavy ticking when cold.
When it is in a pull or lag does it knock. Mine does when i first crank it and when i am going up a hill around 1200 rpm. I would also like to know this. It dont matter if it cold or hot
Check for the infamous driverside crack in the exhaust manifold between the rear two cyclinders. Remember hearing something about a cracked exhaust making a ticking noiise on start up then going away as it warms up. Hope this helps.
