Will REDEX do any damage ....

Glenn Butcher · February 20, 2003, 09:34:12 AM

Just before you fill up the fuel - in the fuel tank. Can be done afterwards. Should tell you on the bottle.

any recommendations?!... My turbo II is a little lumpy at tickover and hunts a little from time to time (doesnt seem to be dependant on heat, how you\'ve been driving it, etc.) but a blip on the throttle stops it... ...I am guessing it could be injectors, as I had similar symptoms on my mini a while ago and injector cleaner sorted it straight away...

When i bought my T2 a while ago it (not very up on Rotarys) it did\'nt run very well, could\'nt make it idle below 1000rpm and felt very unresponcive, so i found 2 of the 6 Apex seals to be damaged (blown corners, 2pc Hurleys) so me being me thought it runs! its having a new engine! so lets see if i can kill this one.

So i dumped 500ml of redex in 1/2 a tank of fuel, put the Cheapest Unleaded fuel i could find in it and genraly abused it (Jus had first hand experiance of a T2 doing 100yard burn outs from cold). 6 months later after driving it like a stole it for the full time it still ran! and felt no diffrent from when i first bought it, people tell me the Rotarys are very easly blown MMM i think an amount of Luck is to do with it.

I have to admit now i would not think about doing that sort of stuff in the car (it was a shed and i could not care less if i damaged it) but after spending lots of cash on it i could not bring myself to open it up whilst cold.

So what i would say is if you cant take the Injectors out and have them cleaned properly read the Instructions and put the proper amount of Redex in, wont do any damage.

I have tryed ATF trick and belive me it does not work! i put the 1/3 tea spoon of oil in each of the rotor Baths and left it over night when i came to get it running becouse the Compresion was down anyway it would not clear the oil and just fould the Plugs, it took me three days and 2 sets of Plugs to get it going again.
You could not pay me to put ATF fluid in my car now! Knightmare.

Catboy, Check your Mixture and Plugs.

There is lots of things that cause hunting on T2\'s the Main one is Mixture. it runs fine until the unburnt fuel builds up and causes it to over fuel, does it do it after a few minutes of Idle then clear when driven and then exactly the same when left to Idle again? I had a simalar problem when i forgot ot conect the O2 sencer back up and it went to "get me home mode".

Also do you have the Air pump still on? and what Type plugs are you using?

Could be your Injectors but i would\'nt think so myself.

I dont want to scare you but have you ever done a Compresion test?

Ive not had the car for a while (it was my car in japan about 2 years ago, and now I have finally got the cash uptogether to bring it over here)

Its not hunting wildly, just by about 150rpm, but it seems to be after a short blast mostly... If I blast up the road for about 1/2 mile, then come to a stop at traffic lights, it hunts about 3 or 4 times between 800 and 1000rpm, and then settles to tickover at about 900-950 rpm... ...if you give the throttle a blip when its hunted a couple of times, the rpm goes up, then stops solidly at 900-950rpm...

The engine is pretty good (it was rebuilt about 30,000 miles ago by Hurleys) and the plugs and oil/filters were replaced about 4-weeks ago. Unfortunately I didnt replace the plugs, so I dont know what they are... ...they will be the right plugs though, as the guy who did them is a rotor nut and a good mate... ...unfortunately he is in Japan!

I dont think its anything major, as it only does it occasionally, and it doesnt seem to have had any effect on performance

Any ideas for quick checks would be appreciated

Chris, you asked if the air pump was still fitted. I noticed the other day that our Turbo2 still has the air pump fitted even though it is fitted with a cat replacement pipe. Is it recommended to remove the air pump on these and is there much benefit? When I fitted the stainless steel system on our series one I removed it all. But I dont want to remove it if there are any adverse effects.

catboy · February 24, 2003, 10:41:47 AM

I have a s/s exhaust system too with cat repl. pipe, so this may not be the issue?!...
as I said, I dont think its anything serious, but might be something to investigate a little further just incase...

Ultraman_Cosmo · February 24, 2003, 10:50:01 AM

Sure, I just wondered in there was any power to be gained by removing it

Grizzly · February 24, 2003, 06:26:40 PM

I would sugest you keep the Air pump on as its main perposes in life is to add more air on Idle to stop the car over fueling, this is why i asked.

It has been known for the removal of the Air pump to cause Hunting and over fueling on Idle. There is no real gain for this mod (on Fd\'s its done for saftey as the Bearings have a habit of jaming up causing the belt to snap and the water pump to stop, this in turn causes over heating if not spotted in time)

I am Intrested in what Plugs you have fitted as well as this is also asomthing that causes this sort of problem (coming to a colder climate with cold running plugs etc)

Worth a look.

Do you have a Aftermarket EMS fitted?

i have been informed that someone has taken my air pump out of my 2nd gen ! - still runs fine - just thought i would add my Â£0.02 worth !!

catboy · February 25, 2003, 11:17:40 AM

the whole car is bog-std except for the exhaust system... ...it even has the standard induction set-up at the moment, but I am considering binning that once I have saved some more money after the expensive \' travel ticket\'!...

I might consider changing the plugs anyway, just incase; that way I will know exactly whats in there, and have no doubts... ...I am also considering changing the oil again in the next couple of weeks, as I wondered if the oil might be more suited to the Jap climate (although it does get bloody cold around there in the evenings)

I will get under the car and have a look at the plugs and report back what I find

Grizzly · February 25, 2003, 02:39:12 PM

catboy, Your oil should\'nt make much diffrence but its worth giving it a bit of a Service just to be on the safe side (then you know where you stand) it may be as simple as the Octain level droping and it needs seting up for our fuel? (Jap 105 to our 97)

grinder, Yeh i know i was there, what Rpm does it idle at? if its still at like 750-800 ish and smooth its a sign you have good comp engine.

"grinder, Yeh i know i was there, what Rpm does it idle at? if its still at like 750-800 ish and smooth its a sign you have good comp engine. "

Grizzly · February 25, 2003, 05:32:44 PM

Well yeh if its good Comp you\'ll see beter bhp.

have you done yours?

Chris

grinder · February 25, 2003, 05:34:18 PM

i havent had mine done - but then im worried incase it shows something bad up !

you know anyone who can do it
