Check to see if the afm pipe has'nt popped off.A mate of mine did the same thing doing skids in a industrail area and that pipe popped off and did the same as to what your car is doing.

As R31 Power said...

Check if any of the IC pipes have popped off.

When it idles rough is there a slight trace black smoke out the exhuast?

[daler32]

possibly got water in the engine?? correct me if im wrong but wont that make the car stall and not run properly till its all dried out??

I think he just cooked it and possibly blew off an IC hose.

Thats if he is lucky.

Worse case is its leaned out causing the coolant to boil and exh. valves burnt, possibly even blowing a hole in a piston.

Which is why it a good idea to often throw the car on a dyno every 6 months or a year for a power run to check the AFR's are in check.

Head Gasket, Holed Piston, Burnt Valves.... I would go for the latter... Pull your plugs out and you will find they do not all look the same...

Good Luck

sounds like uve done a head gasket, just the fact that water pouring out of ur overflow is one major factor.

Pull out all ur plugs check for water in ur cylindars and take off ur oil cap and see if its milky....if it is, ure up for a new head bro.

just exactly how long was ur burnout? lol

[black_32]

well i picked it up in the mornin an ic pipe blew off the car then idled fine but has a nasty knock after bout 2500rpm also the oil is low

sounds like its time for an rb30 twin cam build, don't you think joel?

Water coming out of the overflow doesnt nesseserally mean a head gasket. My car used to do it when it was in traffic, but it had a hole in it as well... I also lost my radiator cap and cooked the engine... They will take a fair bit. It was that hot that it wouldnt run and was knocking during idle.... Picked it up in the afternoon and it was fine, but for sure i was lucky with that one.
