Saturn Repair: 1994 Saturn Knocking or tapping noise, 1994 saturn sc1, saturn sc1


Question
I have a 1994 Saturn SC1 1.9 SOC every once and a wile it has a iratic Knocking or tapping noise coming from the belt area or pully side of the engine the changes depending on the RPMs of the enging it sometimes dissaperes all together. The sound comes and goes but the enging seems to run really smooth and quiet when the problem is in remission what do you think could be causing it.   Thanks Robert Gibson  

Answer
hi   well on that side there is the s belt there may be a bearing going bad in there or also the timing chain is inside that cover it may be getting loose are your oil changes up to date if the oil gets bad it may loose oil pressure and then u may hear the noise more.. with intermitant problems it is very hard to solve. if u can catch it doing it again see if u can isolate it what i mean is inside or outside of the engine then get back to me
