Changed Spark Plugs Today and One covered in Oil????
-
or look at the uk-mx3 modders guide:
@74034ec80b:B6 The straight-4 was available in two versions, an 88hp SOHC B6-ME unit which powered 1992 and 1993 models, or a 106hp DOHC/16-valve B6-D unit which was found in 1994 and later models.

@f056ca6fcf=daniel:
hmm i was to believe that the 1.5 imports were DOHC and the uk 1.6's were SOHC? wait for DJ to finish work to be sure lol
Pretty much same engine just smaller bores, different cams and ecu
the 1.5 pumps out more bhp than the standard 1.6They are a B5D, a japanese only version of the the 1.5 SOHC engine that they used a lot in kia's and fords but mazda gave it the ZE treatment with the B6 DOHC head with different cams and a different inlet manifold design

Just to update this post, on Saturday i took the MX3 down to my mates house for the rocker cover gasket change, whilst i was fitting some new speakers back and front, my mate took the rocker cover off, and discovered the gasket was not split anywhere. He checked the plugs and there wasn't any oil on any of them, and they were black on the top of each plug where they spark. He changed the gasket anyway, and suggested it might be the automatic choke causing the hesitancy of the engine. We also could hear some air possibly escaping from somewhere, but after inspecting every pipe on the car, we couldn't find anything. I have new spark plugs, Air filter, Oil and filter, fan belt, and new performance ht leads on order, and will see if that makes things any better, we have also turned the tick over screw up a little to stop the car from stalling when slowing down. I am also looking into the cost of a full stainless steel custom exhaust system, because that could also cause the car to hesitate, especially the cat. Any ideas would be very much appreciated, many thanks.

if its stalling, hesitates a lot, kanaroos a bit and you can hear air when its running, check the plastic pipe from the air filter box to the engine, its a big problem on V6 engines but the 1.6 does have it now and again, any splits, cracks not tightened or air getting in anywhere along that pipe it gets false readings from the sensors.
They are brittle when old so dont pull it about too much but bend it slightly to see if it has cracks etc in the pipe

I think its going to be a case of replacing various parts until we find the problem. Many thanks

I have been looking on the internet for a full Air induction kit for the MX3, which has to include the air pipe aswell, i have seen a lot on ebay, but am unsure which one to go for. For instance there are K&N ones on there, but it says they are for 91-94 reg, which seems as if it wouldn't fit mine. Anyone have any ideas, or links for me to look at please.
Many thanks

you could remake that hole pipe section using silicon bends and aluminium joints with the right size unions welded on .

That looks just what i am looking for, problem is its for the 1.8 v6, and i have the 1.6 DOHC, so i suspect it won't fit.
Thanks

Many thanks
