I'm having an annoyance more than a problem. Upon starting the car, I get a distinct ticking noise that gets faster with me revving the engine. After about 2-4 minutes, once my car is warmed up, it goes away. To me it sounds like an exhaust leak... And my MPG is a little low, so I was thinking my egr pipe had a hole/crack in it. any ideas anyone?

 

Most of the time the ones I've seen have loose plugs. But you know what PITA they are to get a tool on.

 

What do you mean, "loose plugs"?

 

Valvelash could also be an issue if you've got too much clearance on a pushrod. Once the pushrod expands and is filled with warm oil it might expand and take up that slack. Just an idea...

 

Are you kidding ??????

After or before you posted this?

 

They are two seperate issues. I guess I should have stated that in the posts. I know the ticking noise is coming from the egr pipe. The manifold is NOT leaking, the head of the bolt was just broke. The threads were still holding it together. I was just asking if there was something I could do to prevent a future leak from occuring at the manifold due to reduced tightness from broken bolt.

So... Relax! No one is doing the forbidden and double posting in YOUR forum, sir. Peace.

 

I don't think he's pointing out your double post... I think he's pointing out that you are missing a healthy bolt on your exhaust manifold. Do you seriously think "the threads were still holding it together"? First thing I though when I read the topic was exhaust leak.

So... Relax.
