I have a 2nd gen 3sgte smoking on high boost, not on idle and not on normal driving. Could it be my CT26 turbo leaking? or head gasket? there is some oil residue on the compressor inlet. By the way it's a blue smoke.
View 5 RepliesI have a 90 celica, and while I driving today, the engine started smoking. I pulled over and took a look. The smoke was coming from behind the smoke and air filter area. I let it sight for about 2 hours and drove it back home and it wasn't smoking. Both times, it was on the road for about 20 minutes. I got a buddy of mine to take a look and he said that it was caused from the coolant boiling(I didn't think coolant coils boil). And it rained for a week straight, and I haven't driven it since it started raining. Could that have anything to do with it?
View 6 Replies2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.
What are some of the limits of the gt 1zz engines like boost and stock lower end limits? Are like new rods and Pistons ok to upgrade with the stock crank? What can the crank take hp wise. What are the engine common issues? Celica GT 00-06 ....
View 2 RepliesI've got a 2007 pontiac grand prix that I picked up off a guy for $900 and so far it's been a head ache. So far, I've had to replace the power steering pump, pump lining, there's a hole in the radiator, and now a mystery problem that me and my lack of car knowledge can't diagnose.
Smoke/steam (smells burned) is coming from behind the engine and when the wheels are turned, it sounds like a high pitched grinding noise. I checked the oil, its fine. I filled the radiator with water as a temporary fix until I can afford to get the radiator fixed or repaired. Air conditioning only works on max setting. Before the problem occurred, I was pouring water into the extra reservoir when my friend started the car. Maybe the radiator sucked up some air while I was filling the reservoir.
I have a 98 passat b5 turbo. All done to it is k&n filter and exhaust.... I put a boost gauge on it and i only get 3-4 psi... is this normal? it sounds very low. Also a weird thing is that the boost drops off at high rpm.
View 1 RepliesI just got my 04 Passat chipped from APTuning 2 days ago and I was wondering if i need to tighten the gap on my spark plugs? Car runs wonderfully but in high boost it seems to sputter a bit, and i was hoping that tightening the gap was going to solve this issue. If i do have to tighten the gap, do i need to do this for each program? I have 4 programs on the chip (stock, 91 octane, 93 octane and 100 octane). I am sure that i'm going to keep it to 91 octane for 99% of the time.
View 1 RepliesI recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.
So i have a '06 2.0t 6spdman passat. I started getting this high pitch sound (like a boost leak) when under hard acceleration from second gear and up. I went to the dealer today and they replaced my PCV system, and told me that was the noise i was hearing. Pulled out of the dealer like half a block and same thing happened. Then the tech went with me heard the noise, went back put it on a lift. And proceeded to just rev the engine. They say its my Intake system, yet I have had it on the car for 2 and a half years. Could it possibly be the DV???
View 16 RepliesWhen I hit the gas and my turbo reached high boost (15 psi and up), it would slightly sputter and make an odd sound. I even noticed my exhaust made a different exhaust note than usual. While it sputtered the CEL began flashing. I then drove it normally (not high boost) all the way home and it drove completely fine. I'm gonna try and get my codes checked tomorrow.
View 9 RepliesCar started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
I'm having a strange, very high-pitched, noise that seems to be coming from my turbo or (possibly) somewhere else in the engine bay. It sounds very screechy, and it may be paranoia, but I believe it also may have a slight metallic sound to it.
It all started yesterday after changing the thermostat housing for the third time in 2 days (autozone sold me a faulty, warped, housing that leaked after install). During this repair the engine never overheated (it did however leak fluid and go a little low) and the main point for replacement was a stuck thermostat. After finally getting it fixed I took it for a test drive and noticed the horrid noise after hitting a good amount of boost (no gauge installed). The noise occurs when boosting and doesn't happen when spooling in the 3k-4k range. I had no hint of the noise before this.
There doesn't seem to be any drop in performance and it still pulls hard. Hoping this to be a loose exhaust connection or boost leak. May be spooling sound escaping.
Mods:
- short ram air intake with an aem filter
- 3" turbo-back exhausted
- revo chipped
- 4 bar fpr
I'm having a misfire issue on my 1.8t. When I go into high boost I'm getting bogged down and misfiring.
I plugged in my obd2 adapter and it gave me a misfire on cylinder 3. I since cleared the code to try and see if it was a coil pack by switching it to another cylinder, but now the cel won't come back on although the problem persists.
I have recently changed the plugs and the car was fine. I then added a fuel injector treatment and the misfire started shortly afterwards. (coincidence perhaps). It's frustrating as I can't rule out coil packs as my cel won't come back on and my code reader is not displaying any faults.
I did previously have a cel with something about fuel trim bank 3? I am also sure I have a boost leak as the car whistles pretty loud under boost.
Also worth mentioning I have a bit of white smoke sometimes but I'm not using oil or coolant and they are not mixing either. I'm at the end of my tether with this car and just want to try get it back to normal.
Got a 6spd Manual. Just got Unitronic stage 2 about a week ago. Now i got probs with "slipping" "clunks" and "bumps" when I really get on the gas pedal. If I'm just smooth with the gas, no problems but it seems the newly added torque is causing something to freaking slip and it's scaring me every time it happens. Not to mention if I ever need power real quick, I'm just going to be standing still probably clanking down the road trying to get whatever it is slipping to pick up. I don't want to believe it's my clutch because this was just replaced in July 2012. How the can I stop this because I'm not enjoying it and lost all respect for my car for the moment...
View 24 RepliesThe symptoms are as follows.
-No change in performance, functionality, or spooling.
-Loud intermittent screeching noise when building boost above 3500 RPM
-Can only describe the sound as air escaping from a tiny hole, VERY similar to warn brakes, that kind of screech. The intermittent part I would describe as if you were tapping your brakes (and they were screeching) rapidly, so on off on off very quickly.
-Also happens when I let my foot off the gas (Also above 3500 RPM)
-Car has CTS Turbo Intake, 42DD Downpipe, and APR stage 2 software.
I am currently stage 2, drive my car kind of aggressive on a regular basis, and now I hear a squeal under high boost, sounds like air escaping. Boost is not acting any different, I've come to the conclusion that the problem is most likely my revision D DV.
-What does failing REV D sound like???
We are looking at buying the new style Escape, either new or a few years old, but I'm worried about the life of an Eco Boost motor (a 4cyl. turbo scare me).
We drive around 25-30k miles a year, and would like keep it past the 200+k mile mark. I'm concerned about a turbo charge motor holding up that long and what type of issues would i have to look forward too?
We have a 2008 Mariner AWD with the V6 it has 200+k miles on it and it's been an awesome little SUV. i want the same quality in my next vehicle too.
I have a buddy with a 2006 Sonata, 3.3. It has about 138,000 miles on it.
When it gets hot, it will LEAP into gear. As if when you put it in gear, the throttle is pushed open 10% or something. Kinda like you would do with an old Ford or Chevy (like the 70's) that stalls when you put in gear. When it gets really hot, like after driving it for 30 or 40 miles, when you come to a stop, you lose the vacuum boost on the brakes, and the engine just goes on the pre-detonating rampage! It literally sounds like Dodge with Cummins diesel in it! It's fighting you while you struggle to keep it from LAUNCHING off the line. The strange thing is, as it is put back into N or P, it returns to normal instantaneously as if nothing was wrong in the first place.
My bud took it to the dealer, here is what they think it could be:
1. Clogged cats (nope, no back pressure, already checked)
2. Wrong spark plugs (it does not have the OEM direct replacement, it has some kind of dual electrode deal in it, but the part number crosses as an acceptable replacement)
3. The dealer did say that the ecm is up to date and that the throttle body is calibrated. That's what I thought it was in the first place.
In my professional opinion, I think it might be a ragged out timing belt. But I'm a domestic mechanic, not so strong with the imports (not trolling here, seriously, I work with fleets 99% of the time).
And there are no codes either.
My girlfriend has a 03 celica gt with around 126k on it. most resent it has had a problem of high idle its sits anywhere from 1100rpm to 2000rpm. I replaced the the tps sensor figuring it was the problems it seemed to get more consistent with the new tps it now sits at 1100 but it may still be high I don't drive it a lot. And I forgot to mention no engine lite. I've herd its not common with toyota. I also looked for vacuum leaks as well but found nothing.
View 5 RepliesI just bought our 1st. Toyota 03 celica GT 5speed.113000 well cared for miles. My biggest concern is the headlight adjustment. The high beams are similar to aircraft landing lights but the low beams seem to cross with the left side too far to the center. I found the up-down adjuster (wish it had the cab operated feature) but can't find the left-right adjustment.
View 3 RepliesI lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.
