My Rex rebuild

[boosted]

Soz mate you got to have pressure regulated cap ....with flat cap water will flow straight out as hole wont be sealed. If it is sealed and excess pressure builds something will blow rad water seal heater matrix or a hose. I was under impressue fd has no rad  bleed on top of rad like the rx8 has as it has the ast tank? . The expansion tank is purely that excess pressure/ heat cap lifts....if level low vacuum draws fluid back up into system from expansion tank.
Give tgs a ring theres summit wrong with the plumbing.

What might be easier is to do a drawing of current set up and post on here.

car is doing my head in, its my own fault for getting impatient and sending it out to a garage, should have continued myself and completed the project.

so i know the alternator has gone and im in the process of fixing that.

i know the coolant system has gremlins, again i am in the process of fixing that.

a suprise oil leak has appeared,     on my mother in laws driveway

today i went out to move the car as it was in the way and as per usual it didnt start. i am used to this with a (censored)ed battery and no alternator but normally after a bit of charging it will fire reluctantly
(it only struggles as its on a base map, cold weather and no battery)

today it just did not want to play ball though. i noticed that the fuel reg gauge was showing priming pressure as normal and then dropping to 0 instantly.
i was not sure if this was normal so opened up the laptop to inspect the priming times and such.

i wasnt sure if something had happened so reverted back to a auto backup from a known good day. the fans came on and both the coolant and air temp sensors started flashing like mad showing massive impossible values of like 300' so now the car definately wont start.


so in summary, its not driveable, not completed, pissing on the battle axes driveway with no battery or battery charger and every time i try to turn the ignition to look the fans kick in on full speed and everything flashes angrily at me and makes me want to burn it.


how was your day

You gotta draw a line....start again...i know how frustrated you are ...i spent 2 months looking for a misfire lol. Weve all been there....but the matches down.
Buy a new battery.
Who is your nearest proper rotary speciast . The likes of Hayward. Jimmys  WGT guys with a wealth of fd experience its bread and butter to them. Id get a rx7 specialist to finish....and if you need to take a 2 week break....

Your location is not in your profile where abouts are you?

[mikey-t]

im based in Redditch mate, just south of Birmingham. i did take it to a japanese "specialist" and had to recover the car from them after 11 months and nothing but shoddy work.

i am now just spending all my time tracking down there mistakes,

things like

all of the power connections, grounds, etc where finger tight if that

the oil coolers where hooked up wrong

the boot ground was a angle grinder taken to the paint and then a oversized bolt

the battery relocation runs through the bulk head loose, no grommet.

and the list goes on and on and on

its got to the point where i am a little ashamed of taking it to a mechanic in case they think i did these things to it.



i am hoping once i weld a bleed valve or two into the rad and fit my electric water pump that will be the coolant woes over with.

the ecu farting about today i hope is just a sensor that has got wet. but yes your right i need to chill for a bit and take a step back

[boosted]

For the sensor to read max sounds like open circuit poss harness plug connection or such like. Dont know what safety protocols are on your haltech that may be shutting it down.  Who is you closest? Wgt?

[mikey-t]

thats what i thought, cheers dude, it had been raining a real fine rain whilst i was working on the car and they have been subject to lots of coolant so a very probable cause.
i will go on a dry out session tomorow

so other than the other stuff mentioned in my specialists rant thread i started tracing the starter motor issues and doing a complete rewire today.

i think we may have a slight issue within this starter

mmmmm this looks healthy, remember this is a brand new rx8 starter that i put the rx7 nose cone on, it was immaculate when it went on



turns out the ebay vendor is famous for selling shit and chinese rip offs even other companies faulty returns and selling them as new. and when questioned he really gets quite offensive,

so i stripped it down today and found that the push fork was not engaging the cog all the way, in fact just the corner of the teeth were catching,

so rebuild and grease up time.


whilst i am doing that i am going to investigate the wiper motor, the mechanic unplugged it telling me that it got so hot he thought it would catch on fire,

i had not seen his chocking wiring at that point but thought it was best to strip and investigate this also.

soooooo i now face a complete rewire as i have NO faith in what the mechanics did to my car, rubbing wires, bad crimps etc etc so fine tooth comb time


classy wiring



this twitches my cringe gland




now i have done a lot of research and have found all the usual sticky links to the subject but has anyone got a comprehensive list of what can be removed from the horseshoe loom when running single turbo and haltech ecu. i want to attack and relocate eveything but not go as far as the mega money motamec PDM motorsport goodness.

any help is appreciated

[mikey-t]

started on wiper motor inspection,
looks like theres been a tiny bit of ingress and the grease has got hot and aged but i wouldnt say anything t cause it running hot unless of course the wiring is fried,
cleaned everything up, cleaned the brushes etc and repacked with some light grease





cool wiper stop method in these




hoping a lighter wheight grease will ease it off



starter stripped and cleaned up a little bit, will do full inspection later find out where all that metallic swarf came from





a little bit better than it was

[mikey-t]

right so stripped my NEW starter motor down, remember i purchased a rx8 starter BRAND NEW swapped the nose cone for a rx7 cone and installed it,



since then it has started the car maybe 8 times and started grumbling on the last one,



so the top end all seemed ok, maybe a little more worn then i would have liked but OK.

i cleaned it all up and was just going to pjut it back together without checking the motor because hey 8 turnovers,,,, right.



passed my nose over it, whats that smell! needless to say i think i have found a new poster child for buy cheap buy twice!

i was warned about ebay vendor aapoldham after i purchased this, he tends to buy non inspected manufacturer returns, cheap chinese shit etc etc and stickers them up as brand new. and when you complain he really tees off on you! really quite a professional outfit,

anyway i opened her up and was greeted by a vision i can only compare to a grenade impact,

looks like the brushes wore almost instantly, the magnet casings had cracked and chipped and some had even collapsed, spinning into the windings and shorting like a mofo!!!


these pictures should go into every reputable auto electricians waiting room!!




tell me you are not impressed!




are you not entertained!





think i may be phoning wosp up in the morning for a heavy duty wake the dead starter

[Casey]

That's a horrendous mess!

[re japi]

Umm... wow... ohh crap 

[mikey-t]

I think I need to be knighted by the rotary overlords when I finally get this out on the road!

[re japi]

Thats true, you should Damn... But keep up the fight, youl get there!
