#4007 of 4030 2002 mazda millenia 2.5L Engin noise
Oct 04, 2010 (8:51 am)
2002 mazda millenia 2.5L base model got loud engine noise after start up or idling. the noise seems to almost dissappear or much less noticable when rpm above 2000rpm. Check engine light on with code 0300, 0350 and 0421. Changed all spark plugs recently. The local mechanics told me the noise seems from inside timing belt cover, front of oil pan, rear upper valve train and water pump. I read one post said bad timing belt tensioner could cause engine noise/knocking. Timing belt never replaced on this car. Can anyone kindly provide the advice or similar experience? Many thanks.

It seems I get the similar problems (post 4007). I just wonder if you have found the causes. Thanks.
#4009 of 4030 02 2.5 with leaking valve cover gasket

I have a 2002 P and the dealer and oil change shop have both told me that I have a leaking valve cover gasket. I guess this is the reason that I smell a burning smell after I drive for awhile. Is this a serious problem that needs immediate attention? Also, is this a difficult and expensive repair? Please note that I also need to replace my EGR valve(??) and would like to know if this is costly.

You have the 2.5, so neither repair should be too pricey. Shop around if you don't already have a regular mechanic.

I had this same noise and eventually timing belt sliped and engine died after replacing tensioner and new belt ran great.

Did you ever figure out what caused the tcs lights to come on and the car jerking? I am having the same problem. Brought it to a mechanic (not dealer) after $1500. He gave up and told me to go to the dealer. This is driving me crazy. I have to put the car in neutral and restart while driving. any help is greatly appreciated.
