Hey people...... it's a 302 with EFI.
I've wondered about some strange engine noise since I started driving this car (about 2 years now). My household has had the car for 18 of it's 20 (or
21?) year life...(parents bought a month before I was born).First time I heard it I freaked.......told my dad about it. It's a staccatto clack sound....almost sounds like rockers makin' noise.....it's proportional to engine rpm, but I really don't hear it as much at higher rpms (I barley, if at all, hear it at high speed idle, but when it kicks down to normal, it appears, and at gradual throttle increase, the sound level of that noise decreases).....mayber just cause the exaust and all the noise in general is louder.....
My dad said it'd been makin that noise ever since they got it, he never figured out what it was. We'ver had any trouble with the engine before, other than some crap getting stuck in the EGR valve holding it open. The water pump has probably been up 3 or 4 times. We've inspected under valve covers. The thing runs absoloutly great, I can totally step on it and make it to 60 in a little over 14 seconds (woop-te-doo....), almost no pre-ignition, and I put 87 in it. it has about..... 135,000 miles on it (I know not that much!...small town). But it just bugs me!
Anyway, if anyone has some ideas on what this mysterious sound could be...please reply!
Thanks.
Nic
