clicking from top of the motor...
i am getting clicking from the top section of the motor. it is pretty slow (but faster than the IACV clicking) but as rpms increase the speed of the ticking also increases. would my injectors be clicking if they are bad? i have heard the noise before then it went away and its back after a hard romp from 1st through 3rd.
if not the injectors could it be something else? valves? just need some insight. thanks.

Well injectors do click, I'd do the ol' s***hascope trick and take a piece of vac tubing, and start putting one end up to your ear and the other end to parts of your engine (injectors, etc) and see if you can isolate it.

I'm having that same clicking right now. It doesn't seem to be the injectors, so I guess I'll check the IACV. That's the only part that's been constant. I had this sound w/ stock injectors, 370's, now the 660's. And it happened w/ my old motor as well as the new one.

Haha, I tried Seafoam too, and it didn't make any difference. I honestly don't think that stuff works.
Good luck finding the problem.

i guess its time to put the stock injectors in and see if the noise subsides.

i noticed a little puff of smoke (2 seconds) that came out on the timing chain side. the smell is also there still. if i had a problem with the timing chain...would it be making this ticking noise and giving off a strange burning smell?
the ticking is relative to the RPMs as i rev the engine the ticks get faster. the noise is very tough to pinpoint with the blower screaming. not to mention it seems to in the area of the blower and timing chain cover so that makes it nearly impossible to isolate it.
it surely doesnt seem like the injectors. the car still runs strong and smooth. i am noticing that at idle the vibrations in the car (shifter, pedals etc etc) are a little more pronounced. i can even see the engine showing a little more movement in the engine bay. but like i said the car runs fine and strong still.
what are the symptoms of a bad timing chain?

Try putting on ther stock belt so you can hear whats going on in there. I swear when I had my stock belt on I heard a little rattle sound coming from the timing chain area. I think once it warmed up it quited down. I was and am in denial so I basically ignored it and went on my way. As much time as I spend with this car you would think it gave hand jobs or something
#14
That is what I had going on until I blew my motor form detonation. Run a compression chek and see what you compression looks like. I thaough when they tore down my motor it was from the little peices of the piston heads bouncing around.

yeah i will have to do that....
funny thing is is that the clicking is very 'uniform'. its not like something is loose banging around. this really has be baffled. i am also giving a possibility to it being something drivetrain related. who knows.

call me stupid but have you done any exhaust work lately? possibly an exhaust leak. i had a pretty big one that sounded like a card in spokes drove me nuts. sometimes its hard to judge a sound with all the noise from everything else.
#20
Paul now that I think about it that did sound like it could be an exhaust leak. seems like the only thing it could be to me that would sound like that and increase speed when the engine is revved.

Without all the V1 screem, you may be able to get a better location on it and taking that blower off doesnt take all that much time either...
Just an idea

yeah next step is yanking the blower and going from there i guess.
i just want to do one thing at a time so i dont create more problems associated with changing a whole bunch of things at once.

It was one of the pullies and not the timing chain tensioner.

Im getting a little knock on the Chain side of the engine...it may be the blower making some noise

The car will run (for a while) with no belt - until the battery dies. (probably 45 minutes from a charged battery) - enough time to test this. I know because my belt snapped and I drove about 6 miles to get home - since our water pumps run off the chain and not the belt - there's no real danger.
You can just loosen the SC belt and pull it up and lay it on the side of the engine bay while you test.

i was looking at the belt tensioner. the bolt with the 14mm nut wasnt securely fitted into channel. the nut was flush with the end of the bolt threads. i got it back into place (3-4 threads visable) thought that might have been the problem. but no, its still there. i guess i will see how the stock belt sounds on there. grrr. one thing at a time.

oook, i put the stock belt back on...now the car wont start. everything looks kosher. i didnt touch anything that would have an effect on the car starting did i? am i missing something here?
when i turn the key, it just sort of makes a click then doesnt do anything.
now i have been having a problem where on the first turn of the key it doesnt do anything....but after a re-clutch it usually starts up fine. now i am getting nothing. it started up fine an hour before. just changed the belt, now nothing.
this is awesome.

Chek the cam sensor plug that plugs in thru the SC mounting plate. Make sure it is pluged in, if it is make sure it is not pinched. That will not the car to start. But it will still turn over.
If you car is not turning over then your problem has nothing to do with what you have done in the last hour.
