new cam and followers and still sounds cammy on no.1 cylinder?
Asked by kylie.doranAnswer
what is the noise you are getting ? explain "cammy" for me .. is it a ..tick tick .. could it be a slight exhaust manifold gasket leak ?
still sounds cammy on no1 cylinder. more like a "quick knocking" sound.
could be a bad knock sensor signal affecting the timing ?
Knock Sensor
The Knock Sensor (KS) is a tuned accelerometer located on the engine, which converts engine vibration to an electrical signal. Powertrain control module uses this signal to determine the presence of engine knock and retards spark timing accordingly.
does that mean the sensor could be faulty? would it require a new one?
it may not have been tightened back up when repalced ..or may be faulty .. sometimes when timing is slightly out engine gets hot and you get a spark knock .. this could be the knocking you are hearing ? who did the repair ?
