Question about 2004 Mazda 3
I have a 2004 Mazda 3 with a 2.3l motor that has right around 100k miles on it. The only problem I am having with it is that it starts knocking on the top end as soon as it gets warm. I took it to a mechanic and his guess is that it might be a valve but I am looking for the real answer. Any suggestions are deeply appreciated!!!

I would check the sway bar linkages, they are usually the first to go, and they are only $40. Its an easy 'do it yourself' project, remove the old one with torches or a grinder (with a small cutting wheel). You can also use a vise grip and sockets but it takes longer.
You can't tell these are damaged until you remove the part. I change mine every 100 000km or so.

The check engine light comes on when there is a problem with your engine and throws a code which it then stores. That code can be "read" by an OBDI/OBDII scanner and should give you the info you need. If it was scanned and the codes "read" the check engine light should of been re-set. If your car is running well have your mechanic re-set it; if it comes on again take it and have it checked again. No system is fool proof and there may still be a problem. Hope this helps.

You have the wrong type hose on the pcv valvle. It isn't vacuum hose.
