All done and back together.
Went pretty well apart from the sheared anti roll bar bracket stud. Grrrr...

I went for the MX5 Parts all in one package but added the front crank seal plus the two cam seals. Which engine is it? 1.6 short nose? 1.6 long nose? 1.8? I've got a bit of a squeak and the belts on mine look tired. I have no idea when they were last changed, so was going to do this job too.
Question is, how do I know what length of 1.6 nose I have?

Question is, how do I know what length of 1.6 nose I have? 'Shortnose' (early / '89 to ~ mid '91) crank pulley has 4 slots. 'big' nose crank pulley have 8 slots... the 1.8 & later (mk2 onwards??) 1.6's have a diferent pulley for 'multi-vee' belts that is 'plain' without slots and interchangable with the 8 slot items if you also use corresponding alternator & waterpulp pulleys for the improved belt design  ALSO.... 1.6 & 1.8 mk1 waterpumps differ as the alternator adjustment strap mounts on a seperate (cylinderblock) mounted bracket on the 1.6 whereas the 1.8 have the strap bolted to a lug on the waterpump. also the 1.6 & 1.8 have diferent cambelt tensioner bolt threading, one in the cylinderblock with a plain / clearance hole in the waterpump and the other uses a shorter bolt that threads into the waterpump only..... ^^ but I cannot remember which  Rich. |

Heheh OK thanks - mine is a 1.6 so the last couple of points are moot for me anyway. Mine is a 91 but don't know when in 91 so will have a look at the crank pulley :-)
Cheers!

Ah yes, I did that when I first joined on here. 1991 month 9, so September. That could be mid or late so will probably still need to look at the crank pulley! |

Had a look last night, crank pulley has 8 holes so that makes it a long nose. Also noticed a load of wet-looking (not oily) gunge below the power steering pump, and power steering fluid level is low, so might have a leak somewhere  |

I found some Slick 50 at a discount in Halfords while getting some other stuff, so topped it up with that. Will check later whether it lost any during a sprint I did yesterday!
Also, to get back on topic, I ordered a timing belt change kit via MX5 Heaven on ebay, and they also sent me a water pump that I didn't order. I had already ordered one somewhere else via ebay so will have a spare for next time :-)

Halfway through this job now, and after my initial surprise that there was *another* radiator in the car, I realised it was for the air conditioning. Mine doesn't work, and surely putting the roof down is a better alternative anyway, so I was thinking of getting rid of the AC pump, radiator and other gubbins. Of course now I can't drive the car to get it de-gassed unless I finish the cam belt job, which kind of defeats the point of doing the AC delete while everything else is being done. Of course the AC may not be working because it hasn't got any gas in it anyway...
So, does anyone know how to check the gas level in the AC without it disappearing up into the ozone layer?

theres a 'schraider' valve in the ac pipework (similar to a tyre valve) that you can 'press' to check for pressure, chances are the system is empty anyway Rich. |

Had a bit of a wrestle with the water pump and hoses today (I'm replacing all the hoses as I go, with Stoney Racing ones), and discovered that the outlet pipe (metal pipe between radiator bottom and water pump, in between two hoses) is badly corroded. Was surprised to see the only place to get them was MX5Parts at £40 for a new one, so I found a used one from Suffolk Mazda at £13 instead. Seems daft to pay more for the pipe than I paid for the water pump itself!
