Bad turbo?!?!

[talon187]

What kind of noise would my turbo make if it went? somthing is making woogrr kinda noise and its loud and it only makes it when the rpms build up any input would be great thank you

You had better pull the turbo inlet pipe and check the shaft for play. Actually it sounds like the turbo has gone bad and will have NO play. Time for a nre blower but check that shaft pronto! Let us know even if you have a question on the turbo inlet pipe or any question you may have being new. Mark

Ok this guy hasn't given us much to work with here. Ok it makes a woogrr noise as the rpm's go up correct? Well what the hell does a woogrr noise sound like? And does it happen all the time when the rpm's go up? Or does it only happen when you really lay into the throttle? Does this noise always come on at the same rpm? Does it make this noise at all at idle? Is there a lack of power? Does the turbo still come on like normally when you hit boost? Are there any other sypmtoms that have been happening too or just this noise? And why do you say it's the turbo? What exactically makes you think it is the turbo and not something else?

As you can see there are many things you haven't told us here. Give us more to work with and we can really try to help you out. Right now you gave us next to nothing to go on. A noise that grows with the rpm's could be alot of things. Like an exhaust leak for instance that ins't letting air out at idle and low rpm's but once your moving alot of air at higher rpm's it starts to leak. See where i'm going with this. Vague descriptions get vague and in correct answers.

If anybody knows what a woogrr noise sounds like please explain it for the class.

WOOGRR: The sound of 2 metal parts rubbibg together that becomes a higher pitch as they revolve faster. woogrr
Check the oil level also. Mark
Restrict driving.

ive checked the oil level it was fine i was on the highway going to school when all the sudden it started it does not make the noise at idel as soon as the gas is touched you start to hear it when u start to let the rpms build it gets really loud i also did a compression test to starting from the 4 cycildener i got 160 then 140 then the last two were about 120...i have a feel my headgasket is leaking but as for the noise like i say it just started out of know where and as soon as the gas is touched its really loud it like screams i took the pipe from the trubo to the intercooler off and the mas air flow sensor off and the pipe and the blade in the turbo still spins...i know the car was beat on alot before i got it and the kid told me he had it on 20 psi for awhile i dno how he managed that its only a 13b turbo...and he said he put a new head on it as well because the timing belt streched and bent values....so he said he did the headgasket and timing belt and balance shaft belt do you think i should pull the trubo off ? because im really thinking about it is there anything in the lower part of the motor that could make it sound somthing like that? i mean in all my life ive never heard a car makes this noise my dad said it almost sound like somthing rubbing on somthing....well thanks for the imput guys

Im surprised someone could tell me that quickly what woogrr sounds like. Sorry if i came off like an ass before. Wasn't intention.

Ok so you checked if the turbo spins and it does. But did you grab the center of the wheel and try to wiggle it around at all? Alittle up and down is ok but any in and out is unacceptable.

Now before you jump to conclusions about your head gasket let's ook at soem other options. Now cylinders 3 and 4 are ok compression wise but 1 and 2 are below the factory service limit. Now not to sound like a dick but are you sure you did the compression test correctly. Did you do it like this this link?

http://www.dsmgrrrl.com/FAQs/compression.htm

Did you try a wet compression test while you were at it? If not go repeat the test and then one more time with a cap full of oil in cylinders 1 and 2. If the compression raises greatly then it's most likely your rings and worn and need to get replaced. If not there are still a couple other things to check, like a leak down test. Here's a link to the instructions.

http://www.dsmgrrrl.com/FAQs/leakdown.htm

You said the timing belt was loose and the previous owner bent some valves. Is it possible that he didn't really replace the head and you still have some slightly bent valves? Or maybe even leaking valve seals.

As for the head gasket being bad. It is possible. Maybe whoever did it ( if it really was done) didn't torque everything down properly and the headgasket is leaking. Do you notice any smoke coming out the back? If so when? At idle, while just cruising or when you get into boost? Also what color is the smoke if there is any? And when you checked your oil did you just pull out the stick and check the level? If so drain the oil and look for coolant mixed in with your oil. That's a sign that may point to your HG as the culprit for the compression.

ok i stuck my hand into the turbo on the side with the mass air flow sensor the blade didnt move left right or up or down....when i did do the compression test i used that site and did it just like it said i didnt do it with the oil yet tho today just isnt my day because like i said before i disconnected the mass air flow sensor and then i said ok ill take the turbo and mainifold off i started doing this i took the stock intercooler peipes out under the hood for more room i took the bolt out to where the turbo gets its oil from the head and realized i had to back the car up so i put the bolt back in hopped into the car went to start it and it tuned over it sounded like it might of started for a split second then turned off then i had power in the car like the headlights radio and all that would work but if i went to acutally start the car it would click i tryed it twice then i lost power to EVERYTHING i mean everything not at all happens when the keys in no door buzzers or anything any ideas on this one ? thanks for all the help you guys im going to check all my fues and stuff in the morring but i doubt thats it i just have this feeling thats not my problem but i hope to god it is thanks again

Please punctuate; that just gave me a headache. Not to be an ass but if I read another post like that from you I am not going to offer my help any more (Im sure others agree). You have been asked to use better grammar on a couple of posts that you have made on this forum.

Did you try to start your car with the MAF and intake pipes disconnected? If so, dont do that again.

Check your battery and alternator. It sounds like you have electrical issues to solve along with the engine noise. Does the noise occur when you rev the motor at idle? Why are you removing the turbo? What are you planning on doing with the turbo off the car? If the noise increases with RPM's but not boost, the problem is not your turbo.

Your compression is not that bad and wouldnt cause the symptoms that you are describing.

No his compression isn't horendous but it is still below the service limit. That compression isn't helping anything. It should be addressed and the proper steps takin to fix it if he really wants it to run properly.

 

[talon187]

yes i still have noise at idel if i rev the engine

In that cause it should be easy to identify the noise. Have someone rev the engine while you look under the hood for where the noise is coming from.

 

[talon187]

i did have someone rev it while i looked under the hood it sounded like possibly the bottom end of the motor... but im still not sure... i still need to figure out why the car has no power at all is there a fuse i could of blown to cause this?

 

[Turbocharged]

If the bottom end is making noise that increases with increasing rpms, then there is an issue with your rod or main bearings. Drop your oil pan and inspect the bearing clearances.

ok i'll have to wait awhile because i'll have to do it outside and one its cold as hell here and secondly its going to snow big time this weekend from whats being said im just wondering what would the balance shafts sound like if they went bad?

 

[90blacktsiawd]

Ok well if you dont have the time to drop the pan can you atleast go and drain the oil? When you do check for any small metal particles in it. Your still going to have to drop the pan anyways but you also have to drain the oil too. It's just one more little clue you can give us then .
