  • Burnt exhaust valves on cylinder 1 (2003 Mazda Protege LX)...Help!

    Mazdas247 · CatBox · 31 Oct 2026

    Long story short, i got a couple holes burnt in the exhaust valves on cylinder 1. I just had an engine rebuild kit done last year which included sending the head to a machine shop, so theoretically the head itself is not too beat up. My question is, can I, as an novice, pull the head and install new valves? I have only ever done small, easy to fix problems on my car up to this point, the most involved item would be replacing my throttle body gasket. Due to lifes little surprises, my... Read more

  • 5spd Protege5 Transmission slack/clunk

    Mazdas247 · tombom292 · 28 Oct 2026

    Hey all. I have a 2003 Protege5, with a 5 speed, and I'm having an issue that feels like something is really loose in the driveline somewhere. Basically, on and off throttle I can feel a thump and see the tach bounce, it feels like there's a ton of slack inside the transmission. It's difficult to describe, so attached are some videos I took of what's happening. I've already replaced motor mounts with nice AWR ones since I thought that's what it was, that did nothing. CVs look fine, I don't... Read more

  • 2003 Protege LX Air Conditioning glitch

    Mazdas247 · LXbeaterGUY · 28 Oct 2026

    I did a search and found a few related posts but they reference forums ("How To") that no longer exist or have dead links. My problem just started. The AC light on the button only comes on briefly then turns off. It'll come on briefly on its own then turn off again. It finally came on when I adjusted my fan speed but flashed on and off between settings. It eventually started working normally. From what I could gather this is a known glitch the appears to be switch panel related. Anyone... Read more

  • Mazda Protege Cold Start problem

    Mazdas247 · Ol'Geezer · 23 Oct 2026

    I recently traded for a 2003 Protege LX with a 2.0L engine. It needed. A timing belt. It didn't fail but it was walking because of a bad tensioner. I've been trying to restore it back to a decent condition. When the engines warm, it will start with one click of the ignition. When it is cool or cold it won't start easily. It just rolls over like it's trying to start but doesn't. After the 3rd or 4th attempt it will usually start. I've checked the IAC valve and it is functional. I will be... Read more

  • Protege5 Leaking Power Steering loop?

    Mazdas247 · Lt. Dan · 26 Sep 2026

    Hey gang - started losing power steering fluid at the right front, and noticed the hard line that runs to the "power steering loop" behind the front bumper is leaking. Made a run to the junkyard, and EVERY SINGLE Protege I found has rusty lines there as well. What's everyone doing for this repair? Aftermarket cooler? Just looping/bypassing with a piece of rubber hose? Is the OEM part still available from Mazda?
