    Hello fellow Mx5 enthusiasts! My 2006 2.0 is burning around 800ml of oil(mobil1 5w30 fully syn) every 1k miles. I am not particularly bothered by having to top up every once in a while but i was worried about the condition of the engine. So I took it for a dry compression test, below are the...

    Hello I recently upgraded to a mark 3 (1.8). Miles from home and with the dipstick showing low, I topped up the engine with about 250ml of 10w 40 oil. Does anyone know if this will have a detrimental effect on the engine? Thanks Steve

    I've recently purchased an Innovate Oil Temp + Pressure gauge. There are 3 earths in total, 1 for each of the 2 sensors, and also 1 for the overall gauge. Can i crimp the 3 earths to make 1 earth and ground this to the chassis somewhere without issue? I don't fancy having wires going off one...

    To cut a long story short... I've been battling constant leaks for over a year now so today I took the engine out to try and fix them. I was hoping it would become obvious with the engine out but it really hasn't. There's some videos below so you can see the extent of the problem. Leaks I've...

    Halfords seem to have an oil sale - most notable Mobil stuff. 23.99 for Mobil 3000 is a good price! It's my car's favourite, but I've not long since done it, so will pass...

    So, I have been plagued by an oil leak for a while now. I replaced the camshaft front seals, front crankshaft seal, cam belt, water pump, pulleys, aux. belts, CAS seal and cam cover seal around 2,000 miles ago. Long story short, I incorrectly seated the cam cover seal thereby cutting it when i...

    I'm about to attempt to replace my valve stem oil seals on my 1992 1.6 eunos, got the head off so no need to worry about valves dropping etc. Got a Haynes manual as well as a Rods guide, so hoping that if I stick to them i'll be alright! Anyone got any hints and tips before I start?

    Hi All, I need some advice. I have been dealing with various oil leaks since I installed the turbo, but my oil feed will not stop leaking at the turbo end. I run PVC sheathed, Braided AN-3 PTFE hose to a banjo on the turbo, the first time this leaked was entirely my fault for not tightening...

    I see a lot of people drilling and tapping their sump to fit their oil return feed, although it may work I'm not a fan of the idea due to how thin the sump is. I'm not sure if its been done, but I had the idea of welding in a piece of bar which is drilled and tapped so you can screw a fitting...

    Brief intro: Bought my first miata saturday just gone, car in general bad shape, very neglected but seemed to have little rust(that I can tell), low mileage and nice hard top so I got it. First problem I want to fix is the dials. Gauges/lights that work are Speedo Petrol (it stays on all the...

    Hi all, Just the last couple days, I've noticed my oil pressure seems lower than it always has been. At idle when fully warmed up, it sits about 2-3mm off the zero line. When revving to around 5-6k, it goes no higher than about 3kg/cm. During warm-up driving, it can be a little jittery i.e...

    hi everybody, I purchased an mx-5 with just under 80k miles. Some time ago, soon after I got this mx5 engine light came on and mechanics found out she was low, very low on oil. Oil was topped up and engine (computer showed some three minor errors, unrelated) light went off. I was brainwashed...

    Hello people, I have an issue..... My little GT17 Turbo is overfilling with oil at WOT as the turbo is diddy and cannot get the oil out fast enough. The return is unrestricted and the crankcase is breating lovely, so its just the sheer amount of oil getting to it. I have a 2mm banjo bolt into...

    I've been told by my garage that if the oil treatment didn't work I'd need to rebuild the engine, it hasn't worked so I now need to know what what I need to do the engine, he has mentioned oil seals possible new pistons. Has anybody used these before? Would they be a straight swap for the...
