whatever happened with your 626, was the engine fried? yesterday i was driving my 99 626 with 200,000 on it and on entering the freeway and accelerating to highway speed it suddenly lost power and will hardly go. i checked with just answer and they think it is the catalytic convertor. just curious to your findings, the symptoms are somewhat similar.
#2451 of 2476 diesel Cambelt broke urgent help by zedz May 03, 2009 (3:37 am)
Hi all. I am a newbie here and need a bit of help. Last night driving down the m6 doing 70mph my cambelt broke. AA got me back home and said the cambelt had boke and at 70 mph the possibility of the valves being bent were very high and the repair cost could be as high as the value of the car itself. Is this true due to the bank holiday i cant get it to the garage for a while. Bought my 2000 model diesel for £2K year and a half ago and no probs at all till now. read somewhere if its a non interferance engine it may be ok have no idea what this means but is it true. sorry for the essay but any help is appreciated.   cheers Replies to this message: Mr_Shiftright (May 03, 2009 7:35 am) zedz (May 04, 2009 12:26 am) Mr_Shiftright (May 04, 2009 6:22 am)

Replying to: zedz (May 03, 2009 3:37 am) Unfortunately I don't have specs on UK models and we don't have this engine in the USA.   But yes, if it is a non-interference engine that you're okay. Basically "interference" means that the pistons, going up and down, are timing by the timing belt NOT to hit the valves, which are above the pistons and also going up and down. Rather like a clockwork. However, on an interference engine, should this "timing" be interrupted by breakage of the belt, the pistons, still spinning, will indeed hit the valves, also still spinning from momentum---even though the valves and pistons are no longer connected by the timing belt.   The reason for interference design is to give a lower engine profile and I would imagine longer piston stroke.   You can't rely on AA to give you accurate info. You need to go to a qualified garage or contact a Mazda dealer about this.   If the valves are bent, you do have a considerable expense to bear---the head must come off, new valves installed, etc. It's generally not about a "whole new engine"---not that drastic, but still here in the states this could be a $1500 job, no problem.

Replying to: Mr_Shiftright (May 03, 2009 7:35 am) Thanks or the reply. Due to bank holday here its a major problem getting a mechanic to look at it. I work 7 miles from home no bus and taxis are expensive and because i just started cant take time off work. will try to ring both the garage and mazda tomorrow to see if they can give me advise before i know if i have to scrap the car. Sad really. Replies to this message: Mr_Shiftright (May 04, 2009 6:22 am)

Replying to: zedz (May 04, 2009 12:26 am) Well not all modern engines are interference and perhaps the diesel needn't be. Do let us know.
#2455 of 2476 Re: 1999 Mazda 626ES v6 issues [p400] by gyates Jun 20, 2009 (7:32 pm)
Replying to: p100 (Apr 13, 2008 7:37 am) Question about the EGR passage cleaning. I just did this to resolve low EGR flow CEL. Cleaned out throttle body and passages, and replaced gasket. Put everything back together, reconnected battery, and started car. Car is idling a little rough now, and is making a squealing sound when idling and when under light throttle. The gasket I used is a Mazda part, and I tightened all 4 throttle bolts very tight. I had to scrape the old gasket off. Any ideas on what is causing the squealing sound, which to me sounds like an air leak? Is it possible I did not put the gasket on correctly?? I would love to see a good pic of a gasket installed correctly, but so far have non found one anywhere. Thanks for any suggestions Replies to this message: askperry (Jul 28, 2009 6:22 am) gyates (Aug 12, 2009 10:04 am)

Replying to: gyates (Jun 20, 2009 7:32 pm) Squealing might be your belt(s) slipping because of the rough idle. The rough idle might be because of a loose vacuum hose. I don't have this model 626, but there are normally lots of vacuum hoses on and around the EGR valve.
#2457 of 2476 Mazda 626 Clunking sound by dixiedc Jul 30, 2009 (9:39 am)
I have a 1998 Mazda 626 that makes a clunking sound when you take off from a stopped position and when you change gears.
