Thread: White smoke on revving

Hi guys

So I finally bit the bullet and replaced my mankey ol' B16A with a second hand one from parts connection. All was running well until I took it in to get the timing done correctly yesterday; (I don't have a timing light, so I did a lazy "yup about there" to get it into the shop - dizzy sitting about 1/2 way) There was no smoke or anything out of the exhaust. When I took it in they shifted it all the way to the back towards the firewall, which I thought was a bit strange but the car still started and ran OK, with a lower idle. Reversing out onto a main road from a friends place tonight the car stalled, can't be my fault on the clutch, its an auto. car started up again with an extremely low idle and I had to hold the brake with my foot on the gas a bit to keep it running while I shifted and took off. Later on after running around a few more places I noticed some white smoke that smells heavily of fuel. it goes away after 10 seconds or so after a rev or two.

I did some searching on the forums and most things seem to point to the head or fuel line area. I'm convinced its the timing being changed that is causing it, but want some backup advice before I go trolling in there.

The only other issue I had with it was we had to open the air mix screw heaps to get it to idle. The air intake at idle is pretty loud, you can hear it over the engine. (Makes for a wicked v-tec noise though )

No CELs, no coolant loss (Finally), no oil loss or any fluids where there shouldn't be.
I also read some forums about just having bad batches of fuel which could possibly be the case. Lately I've been poor so I have been running 91 instead of 95.

Any advice is appreciated

EDIT: Though something tells me I'm making a mountain out of a molehill issue that will be gone in the morning

First things first, get a timing light and check the timing, or take it to another garage that is independant from the issue and get them to check it / adjust if required for you.

If its wrong then you go back to the other garage who adjusted it and complain

care to explain how the break fluid gets into the motor?

Anything is possible just gotta think outside of the circle

brake master leaking into the booster ??????

Or maybe its that mod ive been hearing about 40hp by routing a brake line into the intake, its claimed to
rise the octane rating by 50 points so 98 turns into 148 in body willing to try lose of brakes is normal

Brake fluid can leak into the booster, and from there its directly connected to the intake via the vacume line (how the hell do you spell that, i really should know), and gets sucked through into the intake. So it is possible, and does happen.

Also, white smoke can be coolant,running lean,brakefluid etc etc, just because it is white dont just assume one thing MUST be the issue

True story.

Better story, why was this thread revived in the first place?

I DO work on a lot of cars (All day, erry day, gangster much?), and i have seen it a few times.

It doesnt have to be a MASSIVE leak, a tiny bit of brake fluid makes a lot of smoke. Try putting a little bit in your exhaust and you will see what i mean.

But, you are correct in that you will definitly notice the brakefluid level drops.

British quality

LOL at all you guys who bagged him for suggesting brake fluid in the motor Shame....
