yup you guessed it... another damn PD thread... driving down the road today with the top down and smelt raw fuel after workin on my car all day (pulled the entire interior out to clean and soak all the damn water out of it cause ******* top leaks)

i whipped into a gas station and popped the hood and had a nice size puddle on the LIM.. soaked it up and limped home as fast as i could...

guess since im pretty broke as of now (cast out of the family financially because of what all is going on with me) im just gonna do the banjo bolt and get new injector rings for all the fuel injectors.. off to mazda on monday i guess

grrrrrrrrr why does this have to happen now, i need my car daily and i miss it already

Since we're on the subject of mazda pricing/parts. I've found that going to my dealer is quite a bit cheaper than buying through mazdatrix or mazdaformance! Like for example.

Exhaust manifold is about 17$american through mazdatrix.
If I goto my dealer I get it for like 12$cndn

I think its either the fact that canada mazda and US mazda are totally different companys, or the dealer that im going to isn't marking them up a shitload.

 

Now, let me ask you firsthand...since this is bound to break out into another debate about bolt vs. pd.

Knowing what you know now, which chance would you rather take?

1) leave stock PD in place, or replace with another at a high cost, that could fail in a matter of months or years

OR

2) put a bolt in place of the PD at a very small cost, and worry about "hydraulic hammer" and "pressure waves" that can supposedly cause fuel system component wear/failure and uneven fuel mixtures?

I bet you'd still go with number 2. One can kill your entire car in a heartbeat. The other probably wont do any damage, but*might* cost you a few bucks for used injectors in a few years worst case scenario.

 

OR the fact that, when buying through US based companies, you have to pay extra duties/taxes/shipping on them, versus your local dealer who does not.

 

well kevin your right i am going with number 2....

 

I doubt a brand new PD would fail in a few months. These dampers that are failing are all like 17 years old and up. I think I would pick option C, get one from marren and rig that **** up to fit.

 

i think the PD was more of a safety issue for the fuel pump than for the injectors, but that is just my assumption from dealing with fuel systems for years.

 

few months or a few years? thats a load of crap, you forget how old the newest RX-7 with this problem is.
At the worst youll get something like 10 years out of a FPD.
I see no reason not to besides the price.

 

OR #3 go bye a PD from atkins with out the bleeder hole and if it ever failed it wont spray fuel allover the place, not all PD are fire hazards, 30 bucks IF that at atkins, does not take long to put in

 

cwsttu - Glad you had a leak and not a fire

With all these occurances I'm surprised Mazda never issued a recall on it. I pulled my TII into the garage a few weeks back and got an inkling that there might be a fuel leak; the entire house began to smell like gas. I haven't tried to fire (no pun intended) the engine up since it started leaking. I'm going with option 2 primarily because I have no job and no money.

 

Exhaust manifold? Which one......

... surprised this hasn't come up yet...





man you got lucky, glad it worked out in the end

 

Any brand new part might fail, but apart from a few isolated incidents, there is nothing that lends any weight to your assertion that new PD's will fail within a few months or years. If the original ones can last this long, explain why a new one can't?

 

like i said guys i dont have loads of money and i have to do this... i went to mazda today and ordered 1 banjo bolt, 4 copper crush washers, and all new fuel injector o-rings and the total was 25$ plus i got a free cookie too!!!

 

Well, I've personally seen it, and a couple other guys have posted here saying they've seen it too. I'm sure that carries very little credibility, however. That one dude said his new PD was leaking in <2 years IIRC.

The thing you have to keep in mind is that even though some of them are just now starting to leak, they've been failed for years now. Even 6-7 years ago, when I started working on 7's, I saw all kinds of screws having fallen out of the PD. In my mind, with this condition, the door is 2/3 of the way open for a fuel leak. So even if it took 15 years for them to leak, it probably only took 5-8 for them to fail by the screw falling out.
