Big Mongo

New Member, Just wanted to relay my latest experience with MSD. Tech gave me a RA# for a 100% completely rusted out dizzy, told me to send it back and they would rebuild, no charge.


Now they are holding it hostage for a rebuild fee. Guy who called me was rude and obnoxious. Told him where I would like him to put the dizzy...


Went back to HEI...will never own any MSD products again.

Never had a problem with mine and I can't see how it could "rust" as it's made out of aluminum. The only thing could be the advance arms but mine are coated black.
Been running one since 2000.
Sorry your having problems. Whenever I have issues with customer service I take it up a notch and ask to speak to a supervisor or higher.

If you google it, they had a big problem with that for a long time. Apparently a non vented Cap was part of the cause. Who knows. I had one and it rusted a little bit but not too bad. Some I saw pictures of were absolutely junk.

Never failed but it rusted terribly.

Big Mongo

So I see. Switched from an HEI originally, regret that decision now. Trigger and all steel components, including screws were rusted. Spark scatter could have damaged the engine. All is well that ends well though, no more MSD though.

I agree, I went to a locked out Crane distributor and a programmable box from Daytona Sensors. Much better quality in my opinion.

DUI makes a nice tach drive HEI, curved any way you want.

But, I was disappointed that it was so terribly rusty. I cleaned it up, scraped off the majority of rust and then sprayed it WD-40 fairly liberally.

I've seen FAST multipoint system 2 years old, that was VERY rusted.

Here is my 8572, it is 8-9 years old I think.

carriljc

I'm only using it as a trigger for my FAST EZ EFI 2.0 nowadays. I should take a look at it to see how it's doing.... haven't looked it in a couple of years.

Just FYI, I had a Mallory in my car for 12 years and it looked wonderful up to the day I replaced it with the MSD. If anything, my car spent more time outside when it had the Mallory than it has since I installed the MSD.

BTW.
The 8572/AL-6 is on its way out of the EZ-EFI car/engine.
Going for HEI instead.

The 8572 is going in my SBC 427

Same issue here with an MSD8366 (small cap HEI). Only ran it for a short time before converting to crank trigger and made the MSD into a cam sync. Here's what I found when I took it apart:




Cleaned it up, got rid of the reluctor wheel and made it into a 1x camsync using a Holley hall effect sensor.

I been playing with primarily GM cars for decades, and never once seen a GM/stock dizzy rust.....not points, not HEI, but those are the only two systems they made, for us old car farts that is.....

Present for you all.

That is just fricken ridiculous that they send out a product that will do this then try to charge $120 for a rebuild. When I was researching it, it seemed that it was mainly stuff produced between 2002-2009. Maybe it is still an issue. Done with MSD anyway!

carriljc

I bought mine in 1996.

I should have gone to an electric tach then since now I don't even use the tach drive. It's locked out, vaccum advance removed, and just using it with the EZ-EFI.

I have never seen any other distributor, on any other vehicle, corrode like this. It's appalling. I must say though -- it always worked.

carriljc

Before you put it in the SBC 427. Maybe consider something to mitigate the corrosion issue.

Is this rust/corrosion issue just in the MSD's with tach drive or prevallant in all their Distributors? Mine was purchased in 2006 and still looks new inside. But it does have the larger Ford cap-a-dapt HEI style on it.
I'd be pissed too, if I pulled my cap and it looked like those! I run a MSD Digital 7plus locked out 38deg. with a 20deg. start retard. I cant't imagine running the small cap on a locked out dist., posts a little too close...

I will, have a great day

carriljc

Looks like crap and I cleaned about 3 years ago and sprayed it with WD-40. Not as bad as it was then, but still.....

For today I blew it out with compressed air and then sprayed some more WD-40 throughout.

I wonder if I can scrape the loose rust, clean it up, and apply POR-15? Anybody have any guesses on that?
