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.

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.

Well not all modern engines are interference and perhaps the diesel needn't be. Do let us know.

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

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.

I have a 1998 Mazda 626 that makes a clunking sound when you take off from a stopped position and when you change gears.

Follow-up. Squealing sound was caused by carbon debris that had fallen into the EGR tubes as I cleaned out the main ports inside the throttle body. I opened the throttle body back up, shot some more cleaner down in the tubes, took car out and drove it for a while and squeal is gone. Idle is also back to normal and car is running well. Next on list to do is replace leaking valve cover gaskets. Always something!!

Changing Oil Pump - 99 LX V6

Got a friend that had his oil pump go out. Motor is knocking like an old Singer Sewing Machine.
Does anyone know if any axles or the transmission are in the way of removing the oil pan?
This will depend on whether or not the car gets fixed.
