well the news is in! after towing my car too my work for the second time in 2 weeks now aparently the motor is seized, which personally I find it hard to believe.



now they are basing this on the fact that they could manually crank the engine and the fact that a wire which they say is conected to the started is smoking and sizzling because its trying to crank the motor but cannot because its seized....



now personally i find it very hard to believe that the motor is seized. I have heard and correct me if im wrong but It is almost impossible to maually crank a rotary engine.... also it just seems strange to me the whole scenario so someone please help me think of other possibilities that it could be other than a seized motor because that would suck.... thanks

WTF? I can turn my motor over by grabbing the alternator pulley and twisting it. They can turn the motor over by hand, but when they hit the starter, the wire smokes and they conclude that the motor is seized? Go find a real mechanic!

sorry Im stupid... i meant too say that they could NOT manually crank the motor

If you cant turn the engine even with a breaker bar on the front of the E-shaft either something broke internally or it is gummed up with carbon.



Often if the engine sits for a long time the carbon flakes off and falls down. When you go to spin the engine over the rotor tips scoop up the carbon and it piles up behind them. The pile gets so big that it make it so you cant spin the engine.



A very easy way to fix this is to open the spark plugs and or take off the intake and exhast manifolds. Then spray in lots of carb cleaner and some atf.



This will make the carbon more fluid and you will be able to crank the engine again.



Good luck

make sure you get the good carb cleaner though.... some of the cheaper ones are crap... get the **** that'll eat your skin if you forget to wash your hands afterwards.

well actually it hasnt been sitting at all i drive it every day but i will definitly try it out spraying in some carb cleaner.

Any recent events that would lead you to believe that it might be seized? Like low on oil or overheated?

The fact that the Mech can't turn the motor by hand and the starter won't work=seized. That fact is established.



If you get the plugs out and the intake off you might as well take the exhaust mani off and look in the Exhaust ports. You would be able to 'see' a lot of good info.

the factory procedure for unsticking a stuck engine is to try to turn it backwards. if you dont have the special tool, theres a hole in the bottom of the transmission you can put a prybar on the flywheel with

The easy (old school) way to turn the engine:

Stick it in 4th & push it backwards a little.



If the primary cables are getting hot, you have a weak connection at the hot spot.

dont know the whole story but if you over heated it you might have gotten the apex seals hot enuff to weld them selfs to the block dont know hope this helps.

okay well Ill say this to clear some things up....



I did not overheat the motor, my temp gauge never goes up past a quarter and its been tested and it works so that wasnt it.....



now as for oil its brand new ... I just replaced it last week and its still full right to the top. but one thing oil related is that I never had any oil pressure once the engine was warm it would be 0kg/cm2 at idle and 20kg/cm2 at the most.... could this of seized ther motor? and if so what exactly internally could be damaged.



Also the coolant levels were normal and still are so I would like an explanation and maybe someone more qualified on rotaries too have a look at it before I can believe that its seized.....it pisses me off you know they pulled it in the shop for like 30 minutes and then just tell me its seized I find that not good enough of an explanation let alone an explanation at all like WHY did the motor seize

Yes, low oil pressure could certainly have caused a lockup, although the rotary has a very reliable oil pump. Anytime your oil pressure drops to zero you should immediately find out if the gauge is reading right, but until you do you must assume that it is and find out what's up.

I had a T2 who was BADLY overheated by the previous owner, this wasn't the case at all. Are you sure about that info, I've never heard of a welded apex seal to the rotor https://www.nopistons.com/forums/pub...1047683561.gif

No, you can't weld the apex seal to the housings. By the time things got that hot, everything else would be long long gone.



If you break an apex seal, the can lodge between the rotor and housing, locking the engine. Put a socket and bar on the e-shaft bolt and turn the engine backwards, if it will not move at all, then it is more likely a siezed bearing, which would go along with the low oil pressure.



You can do a visual inspection through the leading plug holes and the exhaust ports, find someone with a boroscope. If you cannot rotate the engine at all, this probably won't tell you much, unles you get lucky and see a trashed apex groove or seal. Bearing failure cannot be seen without a teardown.

yah well I had someone else check it out and it is definitlly seized... **** there goes my rx7 but it was fun while it lasted(4months) I cant afford to fix it right now..... well at least now how I want too fix it so im either gonna keep it or sell it

Did you not read what I said! https://www.nopistons.com/forums/pub...1047683358.gif

well i pulled together like $5000 what do you think i can acomplish with that towards a new motor





oh btw thats canadian dollars

thats 4149.67 usd, you can get a whole lot for that much





id say maybe sell your current one for $1k and put that with your other money and buy something better than what you have

Well i want too rebuild and do a large streetport/ or bridgeport to ther motor

maybe find a blown tii for 1500 or 2k and then rebuild that and do mods with the rest

but then i would need the wiring harness and computer from a t2

i mean buy the whole car, a tii with a blown engine

okay i get it now..... yah its a little hard to find a t2 around here but i will definitly try

where are you? colin had a tii that he was getting rid of a few weeks ago, but i dont know if he got rid of it
