I have a automatic and when i had it in neutral when i rev'd the rpm to about 1200 my engine was making this weird clicking noise but when i rev'd higher and fast it wont make it... I know my cylinder heads are worn a little bit, because my engine purrs when idle...(due to a oil leak which i keep having to ad dmor eoil) but that clicking / clanking noise is worrying me... please tell me if anyone of you knows what this is.. thanks

 

could be your valves need adjusting

 

yep get a feeler guage, a helms manual, and adjust your valves

 

I have a chiltons would that be sufficient for me... I will be doing this myself as to save money... thanks

 

Yea, Chilton's will do the job fine, and since it goes more indepth than Helm's or Haynes, i find it to actually be superior. I wouldve gotten one myself, but i didnt find any at the local book shops, and didnt feel like waiting for a special order, so i settled for Haynes.
