got one leaking and saw the how-to on miata.net
but can't find the O-ring part in the MazdaSpeed pdf
anyone know the Mazda PN or where to get locally (other than dealer)

How about taking the old o-ring to the parts store and finding one that matches? That's what I did.
In fact, I have a spare for a 1.8 I can bring you or we can meet up somewhere. ;) Not sure if the 1.6 is different.
If you can't wait the o-ring I have has the following measurements.
W - 1/8"
I.D. - 1-1/2"
O.D. - 1-3/4"
I saw those dimensions in the how-to directions, but thought I'd at least look into the Mazda one
I need to place an order with MazdaSpeed anyway
I can call them and get the PN, but they were closed yesterday due to the wild fires, so don't know when they'll be back up and in business
I bought one a few months back from Town North for $5.20. The part # on the invoice is 9954-10-3801. Hope this helps.
I should have said for a 1.6 (don't know if they are different for 1.8 )
that PN does show as good on MazdaSpeed for $3.05
thanks
nealb, I got mine from Pepboys. I took what was left of my old one and they matched me up. I think it was .59, and he threw in an extra freebie one, which is yours btw if you want to come get it.
thanks, that's what I'll do (buy O-rings with the dimensions mentioned above) if MazdaSpeed stays closed for longQuote:

I'll just get two and do both cars since it doesn't look hard
Napa has them, they just don't know it.
Take the old one in and they'll match it. That's where I got mine the last time.

where is a good how to on how to do this perhaps i can do mine today too since i am already working on the car?
thanks i will look into those .... they say it is soo easy till i get out there and f something up :(
If the old one is still in one piece (for the most part haha) any place that sells o-rings usually will have the same size and thickness. Also make sure you mark the cam sensor EXACTLY how it came out because it has to go back in the same way. Just use a pencil or sharpie :-) I think it already tells you to do that in those write ups, but I havent looked at them in forever. Now that I think about it I think mine is due again :(
If you don't mark it and line up the marks when you reassemble it you will need to use a timing light to set the timing again. ;)
anyone willing to help me out with this on sat ;)
Hey guys... if you're doing the CAS o-ring, you probably want to go ahead and do your heater hoses at the same time. The oil leaking out of the CAS gets on those hoses underneath and will cause them to go bad over time. They're kind of a PITA, since they're prolly seized onto the fittings, but the best way to get them off is to split them down the side with a good sharp utility knife.
joy more hoses ;) gotta do my coolant ones too they are a bit weak ... vatozone here i come
I believe that's an issue on 1.8 cars as the 1.6 has the CAS on the other side. :confused:
Dunno for sure as I've only owned 1.8s
That is an issue on the 1.8L cars only.Quote:

There are 2 lower radiator hoses on the Miata. One from the radiator do a metal pipe at the side of the engine compartment and one from that metal pipe to the engine.

I have a theory that the whole oil on the heater hose thing is more myth then reality. On my 1.6, the CAS was leaking, but none was getting on the heater hose (as it is on the other side as you have stated). Guess what... my oil free heater hose split just like all those that get blamed on the CAS leak. So did my upper and lower radiator hoses. Coolant hoses are rubber, and exposed to a ton of heat for a long time. They will all eventually split if you don't replace them at a reasonable interval. If your car has over 100k miles on it and you have not replaced them, I would recommend replacing all 9 regardless of oil leaks or how the hoses look.Quote:

When I did the o-ring on mine, I saw that the heater hoses were directly below the CAS and slathered in oil. The hoses were soft and kinda gooey - like the oil had been working on them. If they're just exposed to heat, they'll usually get hard as a rock and eventually split as well. Either way it's bad news...Quote:

good tip on the hoses, but I replaced all 8 coolant hoses on both my 93s this spring
and then after watching a guy bail out of his car at MSR when the heater core split and drenched him with hot coolant, I found a molded hose at NAPA that works to bypass the heater core
installed that on my track car last week
Got a part number?Quote:

this is much longer in the straight section that fits on the back of the head than you need, so just cut to length
has a nice molded 180 curve that you cut an inch or so off the end that fits on the pipe going to the front of the motor
memory says it wasn't cheap, maybe $15
Cool... That will come in handy on my seven.
