Engine knock... Reply #15 – April 14, 2006, 06:12:05 PM Have fun with that. I'm going to let mine alone till I build and drop in a 5.0 HO. It still runs real good so as the old adage goes if it ain't broke don't fix it. Quote Selected
Engine knock... Reply #16 – April 15, 2006, 12:49:29 AM I kind of agree, but feel like it's broke enough, if you know what I mean. I'm having a little trouble letting it go...it's driving me crazy. Nothing like pulling up next to someone wanting to punch it a bit, and all I can hear is NOISE that doesn't belong. Quote Selected
Engine knock... Reply #17 – April 15, 2006, 01:10:29 AM Well, I've already got the HO.I may drive it until it blows and then build something better. I'm not too worried.The sound is incredibly annoying though.I'm actually still wondering if this could be exhaust related. Just haven't had the chance to check. Quote Selected

Reply #18 – April 15, 2006, 01:44:13 AM annother thing that was causing a knocking sound on my motor was a broken pipe going to the smog pump... it was like snapped right off and exhost was coming from it, and just in the rythem it sounded like from 1 or 2 cyl... freaked me the hell out...

I think you just solved the problem I was having... I have the same knocking in my engine, only under load, and from the frequency sounds pretty much like a single cylinder doing odd shiznit. Took a little gander at it just now with a flashlight (gotta love them Eureka experiences) and there we go, broken pipes to the smog pump. Not that my smog pump works, mind you... But I do think that's the cause of my problem right there; crimping that pipe shut oughta solve that right? Quote Selected
Engine knock... Reply #20 – April 21, 2006, 12:33:57 PM Okay, so I used the listen with a stick technique.I put it on the valve cover and could hear the knocking. It is at its loudest at the #3 cylinder. Interestingly enough, this is the same cylinder where my headgasket blew. So, I'm thinking sticky lifter at #3 cylinder. What do you all think? Quote Selected

Do you knwo if it's louder at the top or bottom of the engine? IE: is it louder in the area of the head or the block. If it's louder closer to the block then it might be a wrist pin problem............ Quote Selected
Engine knock... Reply #22 – April 21, 2006, 01:31:35 PM It's louder in the area of the head.I doubt a bad valve since the heads are different than the ones that were on the motor when the gasket blew. I had the heads checked out and they were fine at the time I put them on. Not saying that they couldn't go bad, but I don't think it's likely. Quote Selected
Engine knock... Reply #23 – April 21, 2006, 01:35:16 PM Ok then I'd gues sticky lifter, bad rocker, or possibly bent push rod. Any way you slice it it's time to take off the intake and poke around to see what's going on, which should be great fun, or not:yuck: Quote Selected
Engine knock... Reply #24 – April 21, 2006, 02:10:03 PM Yeah, I just wish I had this problem when I put the Cobra intake on. It would have been easier to fix since I had everything apart to begin with. Oh well, I've had the intake off enough, I have it down to a science. :D Quote Selected
Engine knock... Reply #25 – April 21, 2006, 02:14:16 PM Good luck. I hope it's just a lifter. If you're going to change one though might as well change 'em all (it's a roller cam after all). Quote Selected
Engine knock... Reply #26 – April 21, 2006, 02:43:25 PM Thanks. I'm looking at the lifter sets. 150 and up. Might be a while before I do it. Wait a tic, I haven't gotten my tax return back yet. hmmmmm Quote Selected
