Problems with my head???

mazda bait · November 03, 2004, 05:43:54 PM

Not definitely sure but i think i\'ve blown my head i\'ve got a 92 series 3 rex, and whenever the engine heats and pressurises the system i get coolant being constantly pushed out of the top of the expansion/reservoir tank. I\'ve had the thermostat changed but i\'m still having the same problem. Any advice would be greatly appreciated. Also if it is as bad as i hope it\'s not does anyone know of any garages that could undertake the work in either Northamptonshire or Leicestershire.

Try changing the pressure cap first on the AST tank near to the intercooler.
If that does not work then it maybe terminal.
Yonner is right,you don\'t have a head or head gasket on a rotary.It is the equivalent called the water seals that have failed.
kind regards

This is where my seals had failed, i knew this before i bought the car, but it was the car i wanted, same symptoms! i think it was caused by corrosion,
rebuild done, Well worth it, Now running in

I don\'t suppose i could be so rude as to ask how much it cost to have the re-build. I\'ve had a search on a few sites and 2K seems to be able to buy a re-con engine for a swap? But to be honest i\'m trying to sell her so the cheaper the better.
Also don\'t know if this will make any difference but the car still runs fine when full of water you can probably drive 5-10 miles before it empties?

Hi mate,
Well mine ran reasonably well untill all the water went, its when it overheats it does the damage! when my engine builder Chris did my rebuild i wanted both new housings fitted and apex seals anyway, as i plan to keep the car, but because it had over heated too much too often, while i was trying thermostat, pump, etc, (hoping it would be easy!) it needed front and rear plates as well, ( i decided not to have it ported as a standard RX7 has enough power for me) but even with all those parts i had an excellent price.
Why you selling her? any pics? wouldnt mind another one,

her gorgeous rear!

yonner · November 03, 2004, 09:51:41 PM

how mutch do you want for her?

mazda bait · November 04, 2004, 04:32:04 PM

I honestly don\'t know i was looking for 7k when she was okay, so i dunno, if i knock off 2500 that would be 4500 i guess. I think that\'s pretty fair she has got a lot of extras.
