Yes, the suspension defenitely needs some work. I am busy putting harder springs in and dropping it a bit. I have added an extra anti-rollbar in front aswell. This should help for all that bodyroll.

I am strugeling with very noisy valves. I have set the valve clearances again last night. I decreased the clearance to 8 thou already but it is still very noisy.

On idling the noise is fine, but as soon as i rev it a bit the ticking noise really becomes load.

I suspect that there could be another cause for this noise, maybe play on the rocker shafts or something like that. I cant feel any play with my hands though.

Anyone have any ideas? And how can i check for play on the rockers? Do these motors maybe have a common problem with noisy valves?

I am having some trouble with my engine...

The oil feeder pipe that spray the oil onto the cam got blocked. This caused the cam to wear flat spots and completely ruined my rockers.

I had the cam fixed, as the damage was not to bad. But the rockers is not repairable.

I am really struggling to get new rockers here in South Africa. I found two sets, but both looked even worse than mine.

Do anyone maybe know where i will be able to get some? or of any other cars rockers that might fit or be modified to work on a 1.6 NA motor?

Any help or advice will be much appreciated!!

That family of piston engines - the 1.6, 1.8 and 2.0 (I forget the codes) are pretty unloved here in Australia. I can ask around and see if anyone has an old engine they don't want and strip some rockers out, but they will probably be as worn as the ones that you already have found.

Shame about the rockers as the car looks fantastic. eBay sometimes has some really cheap stuff for these engines. Look under Mazda B1600 pickup of the same year as it used the same engine.

I finally got hold of rockers, so the car is running again... :mrgreen:

I made a few mods to the suspension and this improved the handling a lot!
There are still lots to do, but the next thing I desperately need is some proper tyres... :wink:

Here's some pics of what it looks like now.

Thats awesome. Almost all that body roll is gone. How did you double up on the sway bars?

Hi great car by the way. See if you can get some 6 inch rims and run 205/ 60/ 13 tyres. That will make a huge differance. Good luck!

Amazing what that extra anti-roll bar does.

I did that on my GLC, it made a huge difference.
Are you planning on wider rims & tyres?

Nice Mazda man...keep it a piston engine as they don't get any love compared to the rotary engine
