Is my motor blown-vid
well my motor shakes alot when its running and it doesnt sound like its running right until its really gettin high into the rpms but i wanna know what do u guys think is my motor blown?

well... theres ways to check dude.
also, i would check for vacuum leaks first. |
as far as i can see no vac leaks
|
Sounds Like No Back Pressure
|
Thats pretty much what mine sounded like only it wouldnt rev over 3grand. I havent had it torn apart yet to see what happened. I probly wouldnt keep starting it though, if its a apex it will eat shit up, turbo included.
|
ya i dont have a cluster or anything hooked up so idk what rpm it goes to but it seems pretty high
|
I've seen fried plugs make 'em run like that but I would check everything. Stop running it though until you know for sure it's not an apex. Do a compression check.
|
Looks and sounds like my old n/a motor when I blew coolant seals. White smoke and all.
|
Does the smoke smell sweet?
Or does it smell rich? |
My N/A would do that in the winter when it was freeze-your-balls-off-cold outside.
Smelled like it was running really damn rich BTW.... I never did smell any coolant. |
doesnt sound blown to me.
would rev much slower. |
Yeah... it sounds really nice!
"Brap brap brap...." Beautiful. |
yeah, I would check the plugs, plug wires, ignitors, etc. If it gets to a smooth rev at some point, I think that it might not be a blown motor. When I blew an apex seal, it sounded like my lawn mower, with less horsepower.
|
Sounds and looks like its running EXTREMELY rich for some reason. Check for fuel leaks. Mine ran the EXACT same way when fuel was spewing out of my primary fuel rail. White smoke and all! Mine has a haltech as well. What mods do you have done to the car? Stock ECU? If you dont have a compression tester, do the poor mans compression test. Take out all the spark plugs, and crank the engine. You should hear equal strong pulses on each face of the rotor (6 times). If you hear a weak pulse, you need a rebuild or a new engine. :/
|
all the plugs wires and stuff are fine juss changed them running stock ecu....im gonna get a comp tester as soon as i can to fined out for sure and it smells super rich
|
Try the poor mans compression test right now!! :)
|
well i just went out there and the front rotor sounds all good but the rear one sounds like it may be weak but they are very close so its hard to tell without a comp tester
|
Take a vid again of it.
|
is your timing off?
|
i dont know cuz i dont got the tools to check if the timing is off
|
It seems to be maybe a wiring or vacuum problem IMO. The timing could be it though. It just seems that when you run it... it sounds like it's very rich. Seems to have that nice "pop" like it should.
Am I making any sence? |
A timing light is something you should invest in... It will help you years down the road... An RX-7 isn't the kinda car you buy and take to the shop.
|
ok soo i need i timing light and a comp tester....and the engine wiring harness is cut and hacked like u wouldnt belive so the could be a problem
