well, where do i start, drove into the mx5 factory today for 175,000km service and to get my timing belt and cam seals done, as i drove up the drive i heard a clunk (not good i thought to my self), i drove in and we hoisted the car up.

we looked through but could not find anything, we took off all the covers to check the crank shaft nose and there was the problem, it was slightly bent and was out of shape and the groove at the top was about 5mm wider than normal. we went to check it, wiggled it around a bit and it cracked

here are some pics.






but anyway, dick found me an import b6 long nose engine with 50,000k's on it and he is doing the whole thing for $2255.

i was going to get the engine rebuilt next year anyway so i guess this was kind of a good thing.


this is the engine.



cheers,

cheyne

sh*t! Not a cheap experience... Thats pretty crazy that is cracked And that keyway is massivly deformed. Its good that its all being sorted out though. Is the engine to stock specs or are you doing something special?

it's staying stock for now, i did see something nice while i was there though

freddy said that this was a very similar problem to yours ben but alot worse.

Yeah, mine was deformed similarly to that, although not quite as much, mine was more like 1-2 mm out. Gladly mine wasn't bent or cracked though. You didn't notice a wobble of any kind did you? And you had no performance problems either. Hmm, I guess its a good warning to all NA6 owners that this problem is out there and the typical sympton dont always apply.

exactly, and i seems to happen between 150,00 - 200,000.

im just happy that i now have a long nose engine with 50,000kms

cant wait to pick it up tomorrow

Wow that's a quick turnaround! Good on Dick for doing it at such short notice.

Bonus: Don't have to fork out for the 175k service.

i am always very pleased with dicks work, he and his crew do a great job.

and yeah your right, dont have to pay a cent for the service

That is good timing. At least you weren't stuck in the middle of nowhere needing a tow.

I had the same issue but noticed big performance issues....

Mine didnt crack and was repaired with that metal paste concrete stuff???

So... have you got it back yet?

get it back tomorrow, apprently it is a bit more powerful than the old one according to dick, not by much but it is noticable.

i was there today and it was all done nut they still need to bleed the brakes and clutch, adjust handbrake, wash and detail it, and oil the gearbox.

i cant wait it will be like a new car.

and in a month or 2 a full fujitsubo exhaust setup

Nice Yours was already fairly punchy so it must be a good engine then. Enjoy!

well, got the car back today, the new long nose engine is so amazingl smooth compared to my old one, and it has so much more kick! i have no complaints with it what so ever.

and only 50,000kms

I saw your old engine tonight while I was frollicking around over there. Nice and sludgy! :-D
