New Dynaspark installed last December, about 3K miles ago. Engine hot would lose spark and die. Towed to dealer after failure on highway and it died twice in service bay with no codes. Having replaced coil/ICM, wires and plugs, we decided was either puter or opti. I removed opti and took many pictures of it. It was all clean with no oil leaks evident anywhere, as I had replaced all 3 seals in December. No sign of oil leak on chain cover, either. Having read troubles with Dynaspark lately, I replaced it with MSD ProBillet and fixed the problem. I called Dynaspark and talked to a young guy August 2nd that said they don't necessarily use the mitsubishi sensor, just whatever is available at the time even though Bob had posted on another forum a couple of months ago that they are now using only Mitsubishi's. He stated that they have only had "3 or 4 fail because of oil in the unit".

I sent the unit back to them for inspection only. I received email today that says, "oil in the unit"............uh huh.... I emailed back that I have over 4 dozen pics of the unit before sending back and that I wanted them to send the unit back "as is". I intend to post pictures of before sending to them and after return from them. I, also, will probably end up putting a 300 gr. barnes .338 winmag through it while filming with 3 different angles for a good youtube video.

I will update....

 

How did you route the vent lines?

 

correctly and in protective sleeves with no sharp turns. Also, the same way I routed my 2nd GM OEM opti 7 years ago at 66K miles that lasted until I did engine porting in December 2010 at 127K miles.

 

i put an aftermarket unit in my 94 c4 from salvo(baltimore, MD). I think its cardone or dorman, probably. I have 10k miles on mine and I've been driving it everyday since february2011. I paid 250, maybe, and no problems yet, out of that! Now I've replaced two ign mods, two sets of autolite plug wires, and doing away with bosch+4 plugs with regular delcos and msd wires come weekend, due to auto's being so cheap and bosche's having much resistance.

 

......... Its vapor lock ! ...................

 

No, no,......it's.......Dynacrap!

 

I did have a fuel pressure regulator go bad and not maintain residual pressure at shut down (went to zero immediately at shutdown) which did look suspiciously like vapor lock on two occasions but the last 2 or 3 instances were definitely opti since I replaced the regulator and have good fuel pressure now.

 

Are you attempting to add better ventalation?
Can I do this to my low mile bad "GM" opti, using my 44mag redhawk?

 

Sure, and I'll add a couple of 240 gr.'s out of my model 29.

 

Amazing no one can source these mitubishi sensors..you could make a fortune building opts...

 

Hmm, again a predictable event.

 

I sent Bob at Dynaspark a copy to this thread addy last Wednesday. I also emailed that I wanted the unit returned 'as is'. So far, he is maintaining that the Opti had engine oil contamination. As posted earlier, I will update with before and after pics when I receive the unit back from him. Surprised Bob has not posted a comment here, yet (not really).

 

WOW! we recieve the Dynaspark unit back opened it and find a sticky oily residue inside the unit. which is on the reluctor wheel, opti sensor (AIP) (not the mitsubishi) sensor and the inside of the housing. let southern_son know the results and get told I am not telling the truth and that he wants the unit back. I am send his unit back disassembled and all the parts and with the oily residue still in it and on the parts. I had offered to clean and rebuild the unit at no charge but have resinded the offer. I hope that souther_son has the guts to post the pictures as he said he would when he recieves the unit back.

We make the unit the best we can!!! and try to give everyone the best service we can and are willing to help in anyway that we can. If you would have called we might have helped find the problem and fixed your unit free.
I am not on forums to fight or be disrespectful I stand 100% behind our product and again willing to help with issue

Bob

 

Just send the unit back without doing anything further to it, Bob. I would ask that you explain how oil contamination got inside your unit when everything on the outside housing and engine cover is spotless as I requested in my email to you.

 

Now, if I understand this correctly, when you sent this email on the 17th after looking at my unit ;

"......recieved your Dynaspark unit back today and wish you would have contacted us sooner. There seems to be oil in the unit and thats what is cuasing your problems. Please let me know what the next step should be."

..what you meant was - there is a 'sticky oily residue' that is the problem which seems to be from the manufacturing of the unit and we would be happy to honor a warranty service on this item and apologise for all your hard labor in installing and removing a defective unit......

Is this correct? I don't run 'sticky residue oil' in my engine.

I read this to mean - customer problem, how much more money would you like to spend?

As far as your offer of refund, I got 3 emails from you while I was out of pocket; 11:25 - offer of refund or fix, 11:55 - offer rescinded, 11:56 your phone number.

I just got the emails here at 1:30 or so. Your phone number is busy.

 

Whew, now calm down folks. Based on what we know there is apparently an oily residue in the Dynaspark.

The Dynaspark is sealed "with an o-ring and self leveling silicone"

The Dynaspark also has a "sealed" ball bearing good to 1300 RPM. It seems that the Dynaspark should be submersible and outside oil can't get inside.

We know there's vacuum applied to the Dynaspark via the intake manifold

My opinion, based on what's known is one of two possibilities. That is packaging oil used in assemble and was not cleaned off prior to shipment or more likely, there was a failure of the "sealed bearing" and the vacuum from the intake drew the oil vapor in from the back end of the Dynaspark instead of from the filtered air supply..

A check of the intake air hose may be in order. The only other option is that someone is using an air filter that requires oiling and the vacuum applied to the Dynaspark drew this air filter oil into the unit. Air filter oil is kind of sticky and could cause a residue.

One of those scenarios above is correct, just gotta find which one.

 

Sarge, I appreciate your attempt to put a civil tone of decorum on the subject but at this time I am seething in the disgust of being subjected to the ole 'P in my ear and tell me its raining'. This subject has a ways to go before I am satisfied.

I think this is interesting;

Also, I see Bob stated that he was switching to the Mitsubishi sensor 05/13/11 in a response in this thread. Of course, as I stated earlier, the person with whom I spoke 8/02/11 said they are still using whatever sensor they have at the time...

I wasn't trying to be civil but rather to do a little troubleshooting. If it is oily inside....how did it get there. It's quite obvious from threads here and other forums that their quality is not what it once was. A few years ago the Dynaspark was the thing to have but the machining has been simplified (cost cutting), shortcuts have been made and the quality has degraded. They said the new sensor was supposed to be better than the Mitsubishi. Well folks, guess what......didn't work out so well, did it? If it ain't broke, don't fix it. Based on customer complaints and a lack of response from the company I personally wouldn't put one on my lawnmower.

Several years ago I wanted one badly for my Impala but went with the Bailey LTCC instead. I've had no regrets and never had a problem with the unit.

Apparently someone machines a block of aluminum, adds a bearing and a few parts and charges money for the product. They start changing parts to increase their profit without any regard for the longevity. They were supposed to return to the Mitsubishi sensor several months ago but you are still getting the crappy sensor.

I feel that whoever has the Dynaspark manufacturing business right now is killing or has killed the good name that earned them respect in the past. They are going to have to make more money on each unit because I predict the volume is going to go straight down the toilet.

I feel your pain and wish these guys would step up to the plate and practice some good old customer service. With all the complaints of late I'd bet their customer service department would have more employees than their manufacturing facility.

 

1963ss. You are 100% correct on your thoughts. Real quick, I bought the company from the prevous 2 owners who spent alot of time "refining" the dynaspark since the purchase I have been repairing units that the other owners built under warrenty at my cost. I am unable to purchase the mitsibishi sensors unless I buy 20,000 units. I use a sensor purchase through AIP electronics in california. early this year we had sensor issues and had recieved some faulty sensor which tested fine on the o-scope but had problems on the car. we returned them and got the correct sensors in and only use the one from AIP.


for southern_son its your call (1) full refund I keep the unit. (2) full refund I clean, repair and ship the unit back to you. If this is not what you want let me know what is

Bob

 

Too bad all the smaller companies that build these optis can't get together and buy the 20,000 sensors...this would eliminate one major problem for all of them..but I doubt this will happen..only in a perfect world...wonder what 20,000 sensors would cost???
