burning a lot of oil - TriStateTuners.com :: Home of Tristate Auto Enthusiast

04 Turbo Spec · 02-06-2006, 08:29 PM

i am burning a lot of oil and it seems that the car is slower now too. i have a catch can on there but it stoped the oil burning for a while but now it just seems to be getting worse.

any sugestions??

2point4DSM · 02-06-2006, 08:43 PM

I'm going to guess the turbo is going bad. Pull the intake hose and see if there is a lot of wiggle on the shaft. If you can push/pull the shaft up and down and spin it at the same time and hear the blades hitting then it is bad. Or if there is ANY in/out shaft play, that is bad.

Btw, I'm guessing dead turbo cause there is another Vspec on here that just had to replace one.

thanks will give that a look, but if anyone else has any other sugestions that would be great i need all the info i can get.

could it be the piston rings

2point4DSM · 02-06-2006, 09:06 PM

Piston rings... Yes. Do a compression test. Another easy way to tell is if you pull the breather hose and the thing is blowing a lot of air.

Were you running the car low on gas or tuned it on the lean side... maybe lots of knock lately or too much boost?

cburwell · 02-06-2006, 10:24 PM

How many miles did your motor have on it before you turbo charged it? The QR25 is known to have a few issues some of wich can lead to unusual oil consumption. The bulk of these problems were on earlier Qr25's, but even the newer ones have problems.

Have you checked butterfly screws? As was stated a compression test may reveal if anything wierd is going on in the cylinders.

04 Turbo Spec · 02-07-2006, 06:50 PM

No the car has a full tank and was actually tuned rich to be safe. And I am running 7.5 psi of boost which is safe. And the buterflies were removed befor turbo install, so were the balance shafts

The motor has been turbo like three months after I bought the car (new)
So the car has been turbo for 30,000 miles

I also race the car all over the country.

The car is getting tired. hope this info will help

cburwell · 02-08-2006, 11:26 AM

Were there any signs of oil burning before you installed the turbo?

SinistiR · 02-08-2006, 01:03 PM

If you installed a catch can and it helpled slow down the oil comsumption, then you have a blowby problem. A compression and leakdown test would be a good idea.

Did you modify your crank vent system in any way from the factory set up?

HuggyBear · 02-08-2006, 02:01 PM

what weight oil do you run in your car?

That'd be my guess also unfortantly...you might have to overnight parts from Japan.

zerioustt · 02-09-2006, 08:25 AM

If your running anything lighter than a 10-40 in the winter and a 20-50 in the summer you may be blowing oil right past the turbo seals. First things first though..do a compression check pronto! If it comes out ok you have turbo issues.

2point4DSM · 02-09-2006, 08:38 AM

Let me clarify: The question was -- is it possible the piston rings could go bad. So the answer is yes... *anything is possible,* do a compression test to confirm.

Although given the choice btw which will fail first on a well tuned setup, a Japanese motor or Domestic turbo you can bet the turbo will fail first.

In fact, expect to go through 3-4 Garretts before the motor gets tired.

What psi have you been running? Are you blowing smokeout the tail pipe if so at what rpm? Is there any oil lks? What is you knock count like?
Ck the coolant over flow bottle for oil and the oil to see if it looks milky. Pull the pulgs and see if what condition they are in.

Not entirely true, The QR is not by any means a great motor.. particularly the ones made in mexico. My 2002 Spec went through 3 motors before I gave up. And that was no turbo. My advise, put an SR in your garage and wait.

Jeffros Spec V · 02-11-2006, 02:34 PM

Are you using sythetic? My spec burns Sythetic like a pothead in Amsterdam.

Piston rings (compression test), or turbo.

04 Turbo Spec · 02-13-2006, 01:32 AM

im taking it to a shop tomm. to figure out whats wrong. i have a good feeling is the piston rings because if i dont get into boost then there is little to no oil out the exhaust but if i get into boost there is a lot of oil out the pipe when i come to a stop.

i think im gonna use this as an excuse to put forged pistons and rods in for more power

Hope wherever you take its legit and gonna be honest with there findings. And not just say that "hey your rings are blown! Well do all the work for X amount of money." As everyone on here has given ideas what to look for. Do a compression check yourself. Will instantly tell you if its your rings or not.

Also people asked a few questions trying to diagnose your problem and you didn't answer. Please respond.

If you don't know how to do a compression check myself orsomeone on here wouldn't have a problem helping you. But its your car do what you please. Just would hate to see you get ripped. Alota shops are shisty people. Good luck man

Yeah if you want to check compression I have the tool for it.

i am running 7.25 psi and i am blowing smoke out the tail pipe. no oil leaks knock is 0. if i get into boost the smoke wil come out my ehaust after i have come to a stop for about 15-20 sec
