How hot!!?

sbelton · July 02, 2003, 09:20:01 PM

Clive, got it from Vehicle Buyers Japan... it could be anything though I guess - might not be something they knew about, they\'re a great bunch of people there. (it was also RAC inspected) I\'ll see what they can discover on the ramp tomorrow.

Also.. i sent my membership form off a while ago.. weird you\'ve not got it.

As your in Reading, might be worth popping it over to RoTechniks and getting them to have a quick look.

Cheers Dan. That\'s on my way to work !! hehe

I\'ll give them a call tomorrow.

Clive, excellent! Cheers...

Turns out to be a massive oil leak between the gear box and the engine... back of the engine anyway. They\'re fixing it now as we speak. RoTechniks were pretty helpful, thanks Dan. Getting them to fit a bunch of guages whilst they\'ve got the car too hehe - make me feel better ;-)

Thats what I like to hear, another happy rotorhead.

The rear main seal is known for leaking on original engines.
Congrats on the buy. If you would like to help on the problem with heat. BTW It\'s not rotary engines that are notoriously hot it\'s the 13B-REW TT that gets notoriously hot. Rotaries are extremely sensative to heat due to their "sandwhich" assembly. The coolant seals between the rotor housings and plates are very thin. They rest in a small groove to protect them from the combustion elements. If the engine parts get over heated and shift the small coolant "o"ring can become exposed. Once that happens the seal fails and the engine will have to be rebuilt. If you over heat your car even ONCE you willmost likely cook it. I highly recomend installing temp guages to keep a close eye on the operating temps. So strapping a set of glowing hot turbo chargers and two congested catalitic converters to the side of the engine was not the brighteset idea Mazda ever had. Hence the 3rd gen warantee claims in the US back in the mid 90\'s.
Anywho...

Remove the Stock Pre-cat and install a down pipe. That is a pretty common modification to help move heat away from the engine. Also make sure that the cooling system is workling properly to help keep down the temps in the engine bay. There are a ton of other things/ mods that can be done to help butthe down pipe is a good place to start.

I learned all this the hard way. I documented most of it if you are interested in viewing it....

Hi Dave,

I like your Post! Its all truth! The only thing, you can overheat the engine more then once, befor the seal will fail. Off couse, one time may be enogh.

I\'ve seen the pics on your side. You was doing the vakuumhose job. Are you still using silicon hose? Whats your experience?

I\'ve done the vakuumhose job on my FD to. But I\'ve used Viton ( $$$) instead of silicon hoses.

Regards

Iwan

i know that it dangerous to overheat a rotary and now i know what can happen and will if it happens thanks to the great posts here , but what causes it to overheat? Is it sitting in traffic for along time or idiling for a long time because i would have thought that the fan would come on to cool the engine. Or is it driving v.hard for a long time? Cheers

Your correct you might get away with over heating it once or twice possibly. I wouldn\'t rely on that theory though. It\'s risky business. The chances of you over heating your engine twice without causing a coolant seal failure is minimal at best. Feel free to prove me wrong

Sitting in traffic can be dangerous, make sure that you run the A/C if you do. It will kick the radiator fans on to help cool things off some. Hard driving for extended periods of time can be risky. Something like WOT for 30 min at a time would be bad

But you get the jist I\'m sure. I suggest that after any spirted driving (heavy boosting) that you drive the car at least 50mph with no boost just to give the engine a chance to cool off. If the car is parked dont let it run for to long if you can avoid it. Air will not be rushing over the radiator if the car is parked so you see the danger in that.
Other than that just use common sense. In hot weather (which I supose you guys dont see much of in England) say anything above 90 degrees F. take it easy on the car. You can improve the cooling efficency by removing the black weather stripping along the top edge of the firewall to allow hot air to escape the engine bay. Plug any open spaces around the radiator with foam inserts, etc..
Good luck fellas.

I doubt we have more than 1 -2 days a year that exceed or even get close to 90 degrees Farenheit

what about Scotland, can rotary\'s drown in too much rain:bandit

Sorry, I dont drive mine in the rain. It isnt safe. The ass gets a bit squirly if you know what I mean.
LOL
The average summer temerature in Washington DC is 90 degrees F. With apx. 85% humidity. It gets very hot and muggy here in the colonies.
