I just wanted to know why do older cars smoke when you step on the gas? What could be wrong? My friends 1990 integra still works the same since I knew he had the car, still has the same power, but now when he steps on the gas it smokes, can anyone help him out? Anyone know the problem?

What colour is the smoke?

imported_cbishun

white i think, he was showing me the other day but I was in the car not following him.

yO

I could be wrong here but it's usually an indicator of transmission fluid being leaked into the engine and being burned. Also if it is a pale blue/white smoke it's oil.

imported_cbishun

oh well maybe it's the transmission thing but his tranni shift smooth no problems, plus is there a honest mechanic that would actually tell u this? Or would they tell my friend something else.

yO

Well if the mechanic is honest then yeah I'm sure he will tell you the truth. I'm sure more experienced people on this board can help you out.

no way of that happening..
unless yer tranny (auto) is leaking into the rad and yer rad in turn is leaking into yer engine (heads)..

i thought white meant a cracked head gasket
& black means oil burning

yO

Black means too much gas

Blue/white is oil..

White .. could have sworn it was tranny fluid.. oh well.

Whiplash

could be rad fluid.....

ya, black is fuel, blue is oil..

cosmic zx2

ok
i asked the expert...
and it's

white: head gasket is broken (causing coolant to leak and burn)
black is fuel
grey/blue is oil

imported_cbishun

i'm pretty sure the smoke is white, but his oil is also going down. What would he need to fix this problem. I would say his engine is !@#$ed up but it still has power.

SiR-Racer

what about red, yellow and orange smoke?

Whiplash

that's anything burning after a 1/4 ounce of hydro....

Jugglez

you've got at best a blown head gasket. at worst a cracked cylinder. either way if it's a '90 teg consider a rebuild if he plans on keeping the car for several more years.

imported_cbishun

so then basically his engine is messed up if he need a rebuild right? I was thinking Because it still has it's normal power I thought it would just be something small but I guess I'm wrong.

imported_eric

something small can lead to something really expensive.

iTrader: (2)

blue = oil,
black = rich gas/incomplete burn
white = water

neither of which is a good indication. 1st of all find out what colour smoke it is, and how it smells. Then, check compression wet and dry.
