Noises problem
2002 Ford Focus 4 cyl Front Wheel Drive Automatic

My 2002 Focus (2.0 L engine) Started making a loud knocking noise like a metal piece inside the engine, I stopped and pulled over right away and had it Towed to my house, I though for sure the timing belt had broken on it. I opened up and to my surprise I looked at the timing belt and it looked in really good condition, I even started the engine before putting the cover back. It appears the noise is coming from the exhaust or the catalizer converter, is it possible to hear such a loud metallic noise from a sensor or the catalizer?
I would like to hear an opinion before taking out to the local garage.

Thanks all.

Hello there,

I had a loud noise problem with my split port focus a few weeks ago: mine was the egr tube; it was busted.
Look at the tube that goes from the exhaust manifold to your egr valve. If it's busted it'll likely be where the tube connects to the manifold. The focus (especially the split port engine) is notorious for this problem. I think it's an engineering defect or something. Anyhow, the cheapest website I found for this part was " œFordpartsdiscounted' ($60, shipping included). Most websites, as well as your local dealer, charge $120 for this part. It's easy to fix: just unbolt the tube from the exhaust manifold, remove the two vacuum lines that go from the tube to your DPFE sensor on the firewall, unscrew the tube from the egr valve. Install is the reverse; a 10 minutes job (on my car anyway). Make sure you buy an egr tube gasket at your local part store.

Good luck

Thanks for your reply renaudTN,
I check the egr pipe, it looks good , I think the noise is coming from the Rocker/lifters, I opened up and I can see there is a little play (about 1/32) in a couple of roicker/lifters (see image for direction of the play area), Do you think that could be the problem??

Hi there,

Well sorry to hear that was not your problem... That would have been an easy fix.
I just drop by on this website every now and then to answer a few questions, but I'm not affiliated to this website. Now that you've donated, I feel like I should let a certified 2carpro technician answer your question. I will say that though: noises are the result of vibration. If you have two wiggly/loose lifters, it could indeed explain the noise you're hearing. Let's hear what a 2carpro technician has to say about it before you put the cover back on there.
