Idk really. When I got the car, I noticed it but I wanna say it wasn't as bad. But the noise is always there. Even in the higher rpms. The engine noise just drowns out the ticking some.

i also read about a friction gear or something like that. could that be the cause? i just dont want to tear it down, replace something and the noise still be there.

could i just tear down the top end and fix/replace the things that normally cause ticking noises? thats what i would like to do to be honest. just replace everything so the noise dont come back for awhile. this car runs too dang good to not fix it.

Yeah sounds like its coming from the top end of the motor. Try doing the hla treatment and switch your oil weights. But I would say you should do a rebuild. Wouldn't cost very much and everything would be fresh

also, lets say i do decide to tear it apart. what parts am i looking at here? i NEED valve cover gaskets hands down (oil in the spark boot hole or whatever its called). but autozone sells a pair for 90.99! good god. i looked on ebay and found these....

93 02 Ford Probe Mazda MX6 626 1 8L 2 5L V6 DOHC KL Valve Cover Gakset Set | eBay

would these work fine? i dont believe 90 dollars is any where reasonable for a set of valve cover gaskets.

also i know ill need a throttle body gasket, intake gasket. what else would i need?

Sounds like timing belt slap to me. Once you get in there to replace the valve cover gaskets take a good look at the timing belt. Sounds like the tensioner broke and/or one of the idler pulleys is faulty. I don't know how hard it is to remove the upper timing covers on each head but I would do that when making the inspection so you can see better down in there. Unless you're sure that squeak is coming from an alternator pulley or something like that I'd guess the squeak is coming from one of the timing belt components.

Here's a video an I4 owner took of a timing belt cover issue. He thought it was timing belt related but wasn't quite sure.


After driving 2 hours and staying up till 4am helping him fix it here's the result.


Keep in mind this is on an I4 so it sounds a bit different from the V6 to start with. When you hear a rubber on rubber or rubber on metal noise coming from the timing belt area now you know generally what it sounds like. Hopefully that's all it is in your case and not some internal issue. Your issue doesn't sound like metal to metal contact so that's why my guess is timing belt or timing cover related. I've been through it. Let us know how it goes.

Honestly, in person it sounds like a metal ticking sound, instead of a rubber thumping. It comes from the front head usually.

Two things I need to know. What's a good oil additive to clean up the varnish from my lifters? I've been looking at rislone. And what heavier weight of oil should I use?

How are you so sure about seafoam? I've used it once before on my lumina through the vac line and got a smoke show. It is pretty potent smelling stuff though.

Smoke show is the best part lol.

But I guess tomorrow I'll get a can of seafoam and do like you said. Then change out my oil with 10w30.

About how long should I drive my car with the seafoam in it? I've read around and people are saying about 100 miles, then change the oil.

Alright thanks. Now if this works out, my next project is both my front lower control arms. I might order these tomorrow off eBay.

http://www.ebay.com/itm/New-Control-Arm-Kit-Front-Lower-Ford-Probe-Mazda-626-MX-6-93-94-95-96-97-/230912370685?pt=Motors_Car_Truck_Parts_Accessories&fits=Model:MX-6&hash=item35c37327fd&vxp=mtr&_uhb=1

Is this what I need to get? It says it comes with both sides, new ball joint and bushings. For around 70 bucks. Pretty good deal to me.

I'm going to pick up those arms and the valve cover gaskets I mentioned in another post

Check your tie rod ends too. They might need changing, always good to refresh the whole front end. Plus it feels amazing through the steering wheel.
