I want to list some potential problems my car is having:

When its cold (I think its just when the engines cold but I haven’t really tested it) and I go 5k+ rpms it smokes… when I red line it so much smoke is coming out that you cant see any thing behind me till I let off…. (when I go under 5k it doesn’t smoke at all)
The smoke is white …. Pure white.

I here people talking about this… but they usually say theirs smokes before 5k then stops when they get past it… mines backwards of that.

Also my Oil-P gauge (stock 0 – 120) idles at 15 and drives at about 40. is that usual?

when the car is cold it smokes.. end of story... and if u rev up it just pushes more exhaust out causing the smoke to increase and look like alot.. to properly test to see if ur car is burning coolant let it warm up first...once its warmed up u shouldnt see much smoke.. also if its coolant there will be a sweet smell in the exhaust fumes.. also u would be loosing coolant..also u might notice bubbling in the overflow while running....

another thing u could do is remove the radiator cap and start the engine and rev it up to like 2k .. if ur colant seals are weak or blown u will see coolant bubling out of the fill neck.

uumm...no. even if it's a stock gauge it should read 30 at idle and go up as you rev up

Sepher0

it idles 15 and if i rev up it goes up......

how do i fix that?

MattB

why would you EVER rev it when its cold??? STOP THAT ITS BAD!

Sepher0

lol i let it warm up SOME first

MattB

i let my car warmup for 5 minutes every day before i go to school, then i drive below 3000 until it gets to a quarter up the gauge...then i open it up and bring it to 7 ....gotta have some fun...right?

When I say white smoke I don't mean like the kind you can blow out of your mouth in cold air, I mean REAL white smoke!

And I still need some information (help) on my oil pressure...how do I fix it?

if I let it idle long enough it will go to almost 0

--MAstermind--

stock guage = poo poo....ontop of that where exactly are u idling? i know my guage is prettymuch shot unless my OMP is weak....when I personally start my car the oilpressure rises...u can shim the eccentric shaft pellet with 5 M7 washers...www.fc3spro.com its in the tech section.....umm also get an aftermarket guage...Im poor but soon i will have my aftermarket oil pressure guage...if its below 1k the oil pressure should drop...and it should be 30 @1k....60@3000+.....

As far as cold is concerned, that is the norm with these engines....new or old.....so the smoke is ok. It usually stops after it reaches operating temp. As far as your Oil temp gauge is concerned, it should read 60 psi at idle and rise as the engine is accelerated...so i would think that is a bad sign or gauge.

Mine is doing the samething when I rev up to 5k but it happens not only when its cold. Is there popping noises in your exhaust?

you are probably running richer then martha stewart.

Yeah i know, I can smell gasoline from outside the car ALL the time, it also makes some nice jets of flame too. Is there any way I can lean it out without a SAFC?

zerogrips13

ive heard somethign about ebing able to adjust something on the ecu to richen or lean it out, but u might want to ask some more experienced people about it

Sepher0

Mine used to pop... so i removed the Cads and straight piped it, (that fixed most of the smelling and pops) but it made the smoke worse I think...

So buy after market gauges for my oil-p to fix it?

Ruffryder_29

Just buy a gauge.....lol.....The smoke does go away right?

Sepher0

not shure

Ruffryder_29

Not sure??? well that doesnt help...you dont look at the rear of your car at all?? You MAY want to do that....

Sepher0

Just havent had a chance to warm it up and then Floor it....

Ruffryder_29

Try to let it idle till it reaches operating temp....the smoke should be gone. These engines deposit a little oil in the crank case for lubrication. Could just be build up.

Sepher0

ran it till it was opperating temp and then REVed it up a few times ... didnt see any smoke!! God I love this car

You need to let your cars fully warm up before surpassing 3,000 rpm. Fully warming up does not mean the temperature needle is at 1/2, it means that the temperature needle will be at 1/2 AND oil pressure is stabilized (should start high).

Low oil pressure could show it's a good idea for a change, a heavier weight, or a new oil pump. With 20w50 in the winter down here my oil pressure starts at about 60 and goes down to 30 when fully warm. If your oil seals are failing (like from breaking warm up procedure rules) more oil will pass them and make smoke. A heavier weight oil can temporarily reduce this problem.

PLEASE, PLEASE Don't REV the engine to 7,000 rpm until both oil and water are warm, smoke comes from the combustion temps not being high enough to burn oil inection along with the computer keeping the mixture rich to stabilize. Going high before temp is at operating (oil and water) is what breaks seals and the few rotating parts that we have.

With great power comes great responsibility, don't break your engines because you can't wait 5 minutes (you can drive and that will often warm engine up more quickly and more throrougly - but keep the revs and load low).

The temp here is only like 20 - 60 F ... but if you think heavyer oil will help then I guess I will change my oil when i get a chance (I am running 10W30)

A good rule of thumb for oil pressure is 10 lbs for every 1000 RPM...

At idle, 10 psi is good. @ 2k, 20 psi, 3k 30 psi, etc. etc.

I think the big problem is that you're accelerating hard before the oil is warm.

Oil should have higher cold pressure and then drop to a lower pressure when warm.

Nothing wrong with using 10w30 (esp in winter) unless your oil seals are infact bad, but that is not necessarily your problem.

Let the engine fully warm and not letting off hard at high rpms reduces smoke.

If your oil is consistantly at 15psi I would suggest first changing it, even trying a heavier oil, but if your car has a lot of miles on it the oil pump can be wearing down, so be wary of that too.
