Oh shat stop that his head will swell up though he really does go out of his way to help all of us, even sarcastic ones like me.

and the east german judges give Long duck a total score of 9.5 out of 10 (sorry Long Duck, but my wife has ***** and she helps me a lot on the car also so she gets a 10.0 )

No doubt, Longduck is a God when it comes to the SEs..

 

Hey, I appreciate the comments. I've been switching hobbies lately, but will always have at least 1 FB in my garage. (The new Mazda6 sits on the driveway!)

A few years ago, there was a thread going on about whether anybody here actually tried to help anybody else. I, along with many others, commented that we do our best to help out others that have the same attraction to these old cars. At that time, one of the mods stepped in and did some background searches on threads and recent posts and I came out on top for having some of the most helpful thread replies - if not the shortest.

I've always gone out of my way to type as much as I can to help someone out with a problem, and always like to hear when someone has fixed something themselves and learned something along the way. I even met up with an SE owner here in Arizona that had some problems with his fuel pump that we diagnosed - he was happy to have the help, and I was happy to be helping.

In the end, these cars are so old now (the FB's) that there isn't anything that hasn't been broken, stopped working, or fixed in someway by someone. Being able to share that can help keep them on the roads - and that's where they belong.

I'm still trying to 'limp' to 200k miles on my 84SE (sig line) but it's pulling a pretty long 'contrail' (smoke screen) in the mornings and I might have to swap in my spare 13b this winter.

Thanks for the kind words,

 

Good to see that you are still hanging around here, haven't seen you for a bit. You are certainly an example to us all on how to relate needed information in a helpful manner! So, along those lines, have you tried using Lucas Heavy Duty Oil Stabilizer to quell that smoke trail? The stuff really seems to do wonders for aging rotaries.

 

Yeah, I tried it last year when this all happened (adding the MMO to my oil system - don't do it!).

The Lucas 'engine honey' was pretty thick stuff, but by the time I got it into the engine, the carbon around the oil control seals had already been eaten away by the MMO. I ran the honey in anyway, and it didn't change anything. Now, about 10k miles later and about 3 oil changes later, it's finally subsided compared to those early days.

The addition of 1qt of MMO to the oil system like it says on the MMO container was the certain cause of the smoke screen. It was a 1 to 1 correlation - I added the stuff and on starting the car, within minutes it immediately started smoking like you would not believe - my neighbors were coming down to see if my house was on fire. Nothing else was done to it after that, though I did flush the oil system out with fresh 10w30 several times and tried the 'engine honey' as specified above.

The smoke is tolerable, but I try not to get on it too much if I can see any cop cars around - I don't want to get pulled over and then get a ticket for illegal exhaust (no cats), and anything else they can cite me for. The smoking is gone by the time I drive a mile or two - and it only does this in the morning. After the engine heats up, it expands all of the seals inside and once again seals completely to prevent blowby oil from getting into the intake charge.

Lesson learned from me.

Where were you guys that day when I had the bottle of MMO in my hand as I was thinking about putting it into my oil change?!?!

 

Job well done Just like family

 

definately Longduck is a big help to us nOObs...very appreciated
on the MMO subject..is this suggesting or as fact showing that adding Seafoam could be detrimental as well to our rotaries?

 

thank you longduck for your later post.

if i hadnt of read what mmo could do to your engine id probably wouldve done the same. i read that some use mmo to premix because of the blocked off omp. also i read that it is a watered down version of atf. and also i read that you do need some carbon (in the seals?.. dont quite remember where) for some purpose so burning all the carbons out of the 12a (or 13b) or your engine will not run properly.

i believe when i have the time i will change out my oil after 500k (since my car hasnt been running for a few years until recently) and add some lucas to see if it can slow or stop my dowel leak and most likely an omp leak also.

again thanks for your post which goes back to this thread that you have helped many in this forum and just now me.

 

You know ive done the same thing in one of my oil changes... how much did you put in? Mine didnt smoke at all. However I didnt use that much either

 

come on surely hes helped more than this

 

He helped me alot with replacing my pilot bearing. Thanks LongDuck!

 

Yeah, LongDuck just helped me in my SE Idle post. He definatley knows what he is talking about, and knows how to explain stuff so even a retard (like me) can understand what he is trying to tell us. And I give him kudos on having the patience to type long, detailed explanations for things, and for having the patience to read over my thread (se idle problems, how many times has that been asked?) and actually giving a nice reply and helping, even though the question has been asked roughly 9000 times.

Lets award him man of the forums of the year.

 

That's my first ever smiley. I feel very hip and with it now. Time to go listen to Ace of Base to bring myself back to reality.

Yep, I can't say enough good to do justice. His posts are clear, consise and thorough, and I know he's helped alot of people.

Hope my old SE engine will do you well.

Hey, this reminds me. Has anyone seen RX7Doctor around lately?

 

i have to say Kentetsu is my hero i have had all the same problems he has had and helps me alot. from the lights to the lucas oil ( which has helped alot!) and now im trying the sea foam tomorrow.




Long Duck is a a great forum member and has very good input.

 

Thanks, guys.

On the MMO issue, I added 1qt in place of a qt of oil during a routine change, which would be about 4qts oil added and 1qt of MMO.

That's too much. I wouldn't put in any in at all knowing what I know now.

I have 'pre-mixed' MMO with the fuel to keep the fuel injectors clean, and can attest that it's about the only thing that keeps fuel injectors clean on my Infiniti Q45 (8 of them x$265ea!). When I first got that car, it was eating a fuel injector about every 3 months, and was in a cycle that the car was never running right, and ALWAYS at the dealer for a $350-400 injector maintenance. After hearing about MMO from Infiniti owners group, I tried it and they have gone another 35k miles without any failures. I'm a believer there.

Just don't put it in your rotary!

The 'good carbon' is the carbon that forms around your oil control seals at the center of each side of each rotor and keeps the eccentric shaft oil from making it past these seals and into the vacuum side of the intake cycle. This carbon actually helps to seal up the engine and keep the oil control seals securely in place, both reducing their tendency to be worn and/or tear, and also keeping them seated fully in their respective grooves. Once you clear all this 'good carbon' out, it allows the oil to get past until you build it up again. I think this is the primary reason of why my 84SE has gradually been smoking less and less - there's now a new layer of 'good carbon' building up in there, and I'm not in a rush to clean it out this time!

If it ain't broke, don't 'fix' it! HTH,

 

I too have encountered the same problem with my SE as I too have 184k on my engine. I wouldnt reccomend MMO on an old engine the runs fine my motor was naturally sealed by good ol rotary carbon build up and I disturbed it, my smoke is not as bad as Longducks but it appeared immediatly after MMO use. Longduck told me to change oil a few times and I did and it got better but never went away. Who cars I will TII my SE after my deployment. I too thank you Longduck for your concise and descriptive Rx7 know how.

 

I remember the time Longduck helped me repack my muffler bearings. For the life of me I could not firure out why my car had that acceleration problem.


Thatnks for all the good info over the years!

 

Your still ok with MMO in the fuel? My SE has similar issues, next oil change I'll try the Lucas. Or maybe I just need to change my mufler bearings.

I would like to express my appreciation to Longduck and all the regular 1st gen group. You guys are great, and forum is awesome.

Last week I posted up for an SE oil cooler, I found several. Between you guys and a few hard to find parts that Mazdatrix had in stock the SE should be up and running this weekend.
