[nissan240]

just help threw in my friends 200sx motor in. and is blowing white smoke when ever we drive pass 70mph. anyone know what could be the prob? it only blows out white smoke when he drives at 70mph or above! it couldnt be just blowing exessive water could it! anything would help i am stumped.

after it blows smoke do you loose water? or loose oil? could be some part of the head gasket lifting up or something. is the smoke coming from exhaust?

[sicarius82]

or blow by...did u do a compression test? how were the pressures? maybe blown land rings... if so, good game... time for a rebuild...

after smoke is gone i lose water a whole ton of water. i was thinking my headgasket also. about to call the dumbass shop i bought the motor from to see what they could do about it. havent done a compression test yet. will do compression test right away.

yep, head gasket=blown


grats. whered you get the motor from?

[nissan240]

i got it from c&t japanese motors, i believe thats what it was called. off the 60 freeway. should have seen the first motor i picked up from them, water was shooting out of the spark plug wire. this was the second one they gave me because of the first one. they may have just tore the motor apart and did a fucked up rebuild on it!

hey sorry to bring this back from the dead but i got my redtop sr20 f 180sx front clip, from them. The motor runs strong but i notice that some of the parts broke easy?? like my timing chain tensioner outside cover.

Broke easily? Must have been one of those knock off sr20's made in china.
