Golf cart/diesel??

[devinlamothe]

Hey there all,

I've been noticing lately that my engine sounds like a loud gas powered golf card or diesel engine when accelerating.

I remember reading something regarding an exhaust part that caused the noise, but I'm wondering what that would be.

When driving at a constant speed it's fine just when accelerating I can hear the LOUDness of the engine.

Any help would be appreciated!

[Vinceb]

does it seem to lack power when accelerating? or a bit sluggish? chances are if it's louder and sluggish then there is probably a hole somewhere in your exhaust system allowing more emissions to escape than normal.
if not that maybe a problem with your resonator? or the catalytic converter ?

Or a heat shield on the exhaust somewhere.

lol, all the canadians chimed in on this one.

my vote is exhaust leak. loose heat sheild sounds like.....well a loose heat sheild. would sound more like something is being dragged under the car

[devinlamothe]

I've had a loose heat shield before and it was more of a metal clanging sound... but I will check under the car for that.

And no, there is no real hesitation or sluggishness ... it just sounds louder when I am accelerating, like a diesel engine sort of, it's hard to explain.

It could be the CAT but how can I check?

[DavidBlaine]

If you mean diesel sound like the "clickety clack" you hear from most of them I would inspect the exhaust manifold. A cracked manifold would cause a similar noise.

It's more of a putter putter ... like press your lips together and blow lol and that's what it sounds like.

[yaris2010RS]

exhaust leak. check the "flex" pipe portion for holes or leaks.

excessive water in the muffler for some odd reason? did you back into a snow bank and got snow in the exhaust which then melted, and isn't draining out for some reason? lol

[yaris2010RS]

naw, most likely u wouldnt hear a sound from that.

my friend works at a dealership and someone got their car towed to the dealer cuz it wouldnt start. they checked it out and saw the exhaust tip was full of snow and ice, so they left it inside to melt and 2 hours later it started up no problem

Nope that's not it...

I did a quick check of the rubber hoses and everything seems fine. I am now thinking it could be the PCV Valve? I usually change it every year (cheap part) but I haven't for a while.

Also I am due for new spark plugs but I don't think that would be it.

[DavidBlaine]

PCV and Spark Plugs couldn't possibly make the sound you are describing. I am pretty much 100% that it is an exhaust leak somewhere. Take it to an exhaust shop that checks for free. Most will give you a free estimate (at least you will find the problem then).

miss fire or no fire could make a sound but it would throw a computer code

[Vinceb]

if trying to pinpoint an exhaust leak, could always spray some seafoam into the throttle body, have somebody else rev the engine and look underneath to see if you can see any smoke 'leaking' from other parts of the exhaust - I guess exhaust leak is the only one that fits this issue.

[yaris2010RS]

for it to be a exhaust leak and for it to just all of a sudden appear, it wasnt slow and slowly getting worse ur looking for a crack (header) or u blew out the seal between header and exhaust or the flex pipe part has gone bad, i remember a thread from a member in ottawa or quebec that had his flex pipe go bad with reletavitly low km and it was said to be due to city driving.

[devinlamothe]

Thanks guys ... I will probably get someone to rev the engine while see if I can find any smoke or anything ... if that fails I will take it in to see what's wrong. :P

[yaris2010RS]

u probably could have done it when it was cold, i doubt ull see any smoke now.

as someone revs it, spray water along the header and at the joint and see if u see the water getting blown out of the air

[devinlamothe]

It's still cold up north here, so I will prob do it today (its -13).

[yaris2010RS]

lol^ my bad. if u feel like getting FREE professional help for ur issue, come down to the west end toyota meet on wednesday

I have the same problem, sound like a "cheap" car with after market piece of crap on the exaust system.

Yes that explains it LOL

I did go out yesterday and try to see if I could find any leaks but I couldn't see anything.

I guess I will have to take it in.

[the_boss]

I hate the sound but hey! it's part of the game I guess! I wish I could fix it myself but im not that good at all with tools to fix this!

[LittleRedHatchBack]

Hi!

I'm just wondering if you have any idea on the cost of fixing a cracked manifold? Any help would be appreciated!!

The exhaust manifold you mean?

If so the part on ToyoDIY is listed at $216 ... I'm guessing this will run you upwards of $400 from the dealership for the part alone so the repair will most likely be over $1000.

[LittleRedHatchBack]

Is this a part that I can order from anywhere and bring to my mechanic?

[devinlamothe]

There are probably a ton of sites you can order from, but I would make sure you get the proper part # before ordering just to make sure.

Also update on my original issue, I am bringing my car in tomorrow to get checked ... I'll let you know what they find out. I just hope it's not the CAT .. that's like a $2k bill lol :(

[yaris2010RS]

to littleredhatchback, i dont know where in toronto u are but if ur exhaust header is cracked just go to the wreckers and get a newer one. the closest junk yard to me has about 5 or 6 echos that use the same 1.5l vvti engine as us and i get all my parts off these echos (stupid OCV....)

[devinlamothe]

OK I went to the dealership today and I am happy to report it's now FIXED! No more cheap car sound.

They said it was a gasket in the exhaust someplace (they called it a donut?). I can get the part # from the invoice if you'd like. Total cost was $175 part & labour.

I AM HAPPY.

[ecc_33]

if they were calling it a donut it was most likely the gasket between the manifold and the start of the exhaust. Thats what I refer to as a donut gasket

Was it making a louder noise when you gave it gas, that's what is happening for me right now. My mechanic didn't look at it too closely, it was in for brake issues, but he said it could be a cracked manifold or an exhaust gasket. Did you get yours fixed at the dealer?

New Gasket, 2 bolts, 2 springs, 2 nuts..... $175 ? wow

I agree with ECC_33 it would be the gasket shown in this pic (far left, no label).... This could be a yaris exhaust, but i'm not sure - just for illustrative purposes... mine doesn't look like this

Yes, it was only making the noise when I accelerated.

To Vinceb, I think that's the gasket they were talking about - it was actually $48 for the gasket and $28 for whatever else ... the rest was labour cost lol. I know I could have brought this anywhere but USUALLY I get some deals when I go to the dealership... like this time they re-adjusted my rear breaks and also tightened my serp. belt for free.

EDIT:

Part # for the gasket is 17451-21070 (for a 2007 hatch)

The bolts are 90901-05020 x 2 and the springs for the bolts are 9051-35036 x2

[the_boss]

I have an apointment tomorrow and it's called the exaust donut, 139$ plus taxes including instalation. cant wait to have mine fix!
