How about u give me 125 bucks and i spray paint ur pulleys? The OBX is garbage.. actually harmful in more than 1 way.

Jeez. Quit taking meaningless vid of a failed waterpump and surfing the net for ricer gear. Go to Rosenthal's site and get the water pump/timing belt kit and fix your car already.

lots of good advice here

Sounds like this is the best time to get these parts from Rosenthal's as well.

Crank bolt, Woodruff Key, and crank pulley.

and timing belt.

Long nose cranks also fail for the same reason.

I got the water pump on and the timing belt. The Key way looks like it's still new. The woodruff key has no damages. I don't have a picture with the keyway alone but I'll post up whatever I have so far.

Good for you Kevin. You should be all set now.

Ensure you tighten the pulley bolt properly with a torque wrench to the correct value and use locktite like it says in the instructions.

Just started it up and sounds like very bad valve tapping.. possibly timing off? Not too sure.. car isn't bogging or anything. This was recorded when the car got to warm temp.


Compare to the first video I posted, the tapping sounds a bit louder. Ever since I replaced the water pump that "weird sound" went away (atleast that problem is fixed)

Sounds like lifter tick. That is a characteristic of these engines and not harmful. Certainly, if the engine sat while you did maintenance and the lifters bled down (they're hydraulic on your engine), you'll have more tick for a while.

I would recommend an oil change (use a diesel formulation like Rotella, Rotella T-6 is a great synthetic oil for a turbo Miata) and then go for a drive. I'll bet that tick goes away.

Good job on the timing belt and water pump.

I'm not an oil expert or anything but isn't that dangerous for non-diesel engines? Just curious.. Cause those oils are pretty thick and I've only used up to 10w40 for my miata

Rotella T-6 is 5W40 and meets auto spec SM (which far surpasses what your car calls for).

Anti-wear additives for flat-tappet camshafts (like the Miata) have been phased out of new gasoline engine oils in the name of protecting catalytic converters. Most newer cars have roller cams anyway. The diesel oils still have these additives -- although even there things have been getting cut back for similar reasons.

Members here have had good results on oil analyses using diesel formulations. You'll notice a LOT less lifter tick with those oils.

Yes, they're great. Just do what we tell you for once. Rotella's cheapo stuff at walmart is awesome in our engines.

Just finished work and bought me a jug of rotella t6. Lets see if it makes a difference brb!!

Rotella did some magic. Tapping isn't as loud as before. Inspected the car for coolant or oil leaks. It's bone dry. It started making a new sound, like a supercharge belt sound. Not too sure if it's because the timing belt is too tight (I did the method that was mentioned on Mx5unleashed) or the alternator belt is on too tight.
