I few nights ago I wa driving around and was pushing pretty hard. Then I stopped to traffic lights. When lights went green I lifted clutch too quickly and the car choked. When I tried ty start the car it didnīt. I Had to push the gas pedal to the floor and then I got it running...BUT now the idle "vibrates" and the amount of smoke is huge. I also feel a little vibration of the engine when I drive "normally".

When engine is cold I have no problem to start but after a few minute when it get warm only way I get it running is to push the gas pedal to the floor!!!

I checked lower spark plugs and both looked OK and I canīt see any leaking hoses or anything.

Did I blow my engine or is there still hope? (have ~2500miles on a rebuilt)

PS. Havenīt got time to test compression yet.

 

S4 or S5?
The low speed vibration, sounds like it is missing due to low compression on one rotor.
I expect the compression test will not be good - sorry.

 

Sounds like you barfed the car right at a compression/ignition point and when the clutch locked up and the car died, there was no place for the ignition fireball to go but through an apex seal being that the rotors were lock inplace by the drivetrain.... I'll be its the rear rotor..

A quick test is to take the trailings out, remove the egi fuse and have somebody turn the car over.. if you her a few good spliffs and a gap in the pattern..........

 

yea i had that my back rotor had 60/60/60 compression, while my front rotor was a 95/95/95.....according to haynes yo shouldhan't have a difference of more hten 20 psi, but 60 psi is completely unusable either way

 

I had to dig up this old thread because i donīt know WTF to think of this. We found out that the lower sprak plug was dead from the rear rotor and didnīt fire the fuel and thats why the smoke!?

The weird part is the car just dynoed ~300rwhp@9psi but the compressions were 85/120!!! Everything seems to be OK but are they really? that big difference between compression doesnīt sound promising!

Any ideas?

 

Anyone??

 

sir i'm really sorry to inform you, but your rear rotor has herpes

 

storys like that make me scared to drive my car
