exhaust leak? if you have headers they like to loosen up sometimes.. they sound just like a tick.

 

I have a clicking sound coming from under the dash (I think) or engine area on the driver's side can't pinpoint it. It gets louder as I get on the gas but isn't noticeble at idle. I was thinking maybe one of the SPwires is not routed properly and grounding off. Any ideas? It's driving me nuts.

 

valves tappin? pcv valve? altho thats usually on the pass side...correct me if im wrong.

 

An exhaust leak is noticeable at idle, kinda goes "tsk tsk tsk" with a little "tap tap tap" mixed in there.

The PCV valve can rattle when you get on the gas and shut up (or whistle) at idle. reach across the motor from the driver side and hit the throttle with your hand to see if you hear a rattle at the PCV valve. If you do then pinch the hose or just unplug it from the PCV valve and rev it again to see if that is where the noise is coming from.

Do you have any fuses out or electrical issues? Relays click, more so when they're bad.

 

It's my understanding (I haven't checked) these exhaust manifolds do NOT have gaskets. They are installed metal to metal with 2 bolts and 2 studs?

 

Oh my, get gaskets!

 

naw dawg... the factory manifolds have no gaskets.. if you remove them though, you're going to have to use one.. If you loosen them, same thing.. some will say you won't, but more times than not you'll have a leak after messin' with those rascals..

I'm also thinkin' there are six studs.. two on each of the outside cylinders, and two for the interior cylinders.. total of 12 across your engine (both sides)..

if you wanna see an exhaust leak? (I found this by accident)... get a tin of seafoam and run it through the brake booster.. oooooh all the pretty smoke, hopefully comes exclusively out your tail pipes(s).. if it comes from anywhere else, you've discovered a leak..

 

lol. i was cheap when bolting the manifold on my 91. i used muffler cement and it seemed to work good. no leaks and i broke off one of the bolts in the head.

 

Thanks for the help guys.
It turns out the two bolts on the exhaust manifold closest to the firewall on the drivers side were loose. I guess I lucked out cause gaskets are installed in my truck and the click noise is now gone after tightening.

I have a manifold exhaust leak on the passenger side (pretty sure). I tried to get closer to inspect by taking off the air filter box ... but got stuck. Mainly, I think, because there's an odd looking bolt head at the bottom of the inside of the air filter box that turns but doesn't seem to tighten or loosen. It just sort of sits there and keeps me from lifting the box out of the way of having a look at the pax-side exhaust manifold.

Can anybody (a) tell me if I I'm going about this the right way, and (b) if so, tell me how to solve the mystery of the floating hold-down bolt?

Thanks in advance.
