T180 Engine Vibration

[harleymlb]

Can any one offer advice/guidance?

I have a vibration from the engine bay that can be heard within the car. It is normally audiable when travelling at low speeds like in town etc. It can be heard when slowing at junctions or when reversing or moving away slowly and occasionaly on tickover.

My local dealer have been pretty good and have just changed the engine mounts but to no avail! They have acknowledged there is a "vibrating noise" but have not managed to trace it as yet.

If anyone has come accross this perhaps they could let me know and i can pass this on to Toyota.

Although it seeems to be from the driverside when sat behind the wheel when the bonnet is open it sounds like it comes from the air cleaner area.

Very strange! Very puzzled!

hello

what is the source of vibration?

by the way -- diesel or petrol?

what is going on when engines is at idle speed (tickover) -- it's better you to submit youtube with vibrated engine + to listen to his working sound.

I don't suppose it is, but just on the off chance, it is not the engine cover is it?

See here:

If they've changed mounts, I expect it has all been off anyway, but might be worth just popping the cover off and running the engine. Cover usually comes off by grasping both sides and just pulling firmly.

(Some members in the past have allegedly had a repetitive disorder for pulling this cover off on every RAV they see, but I think it maybe now under control :D.)

Not a chance! If only Honda realised that they could sell him a CRV if they had a pull of engine cover ( maybe ) :D

errrrm, 'scuse me.....

......don't talk about him like he's not here. If you must know the engine cover therapy group was first rate but I didn't like the way they just snipped through my bonnet release cable.

Where were we?

There are so many things that can cause a problem like this. To some extent listening is half the battle because it gives somebody with some experience a feel for if its internal or external (sometimes). However, assuming it does it stationary, the normal processes of elimination would involve pressing the clutch to see if it is a gearbox issue and removing the serpentine belt to see if it is any of the auxilliaries and you can see there are several;

T180_serpentine.pdf

After inspecting all the internal parts things start to get a bit more complicated. If you look at this you will see there are lots of rotating parts but it would have to be one that is broken or bent and further to that, one which will continue to function in that state as your car is still running;

T180_engine.pdf

There is a counterbalance unit in the sump. This usually consist of a pair of contra-rotating masses which are timed to counteract the forces of the pistons because they are reciprocating (going up and down).

This sheet shows the features of the FTV (140 bhp like mine) but are carried over to your FHV 180 engine. You can see some of those rotating and reciprocating parts and the vibration damper unit. While you are looking at this pdf pay attention to the crankshaft pulley as it is fitted with a vibration membrane. It is made frome flexible rubber and it is not uncommon for them to fail in which case it will cause a vibration. It is on the outside and should be carefully examined when the serpentine belt is off and before anyone goes delving inside the engine.

Finally, and I hate to say this, we have yet to see a dmf failure on a 2.2 but as we well know it is feasible. Fingers crossed that it isn't.

Best of luck.

PS Does anyone know if the new facelifted CRV has a pull off engine cover???

Thanks Anchorman for the PDF's

The car is still under warranty until September 2010 so all work so far has not cost me anything.

I have had the DMF changed and believe it or not a new serpentine belt as there was a problem with the original (noisy)!

Anyway i will print off the pdf's and take them with me as the car is booked back into Steven Eagle (Aylesbury) for Tuesday 26th January to see if they can "suss" this vibe out.

PS - someone asked if it was petrol or diesel - i thought all T180's were diesel.

Hi Igor,

The vibration is like a resonating noise not a rattle, almost like something is touching the chassis or something.

I cannot record the noise as its only prevelant when sat in the car and i do not think it is loud enough to be picked up by a mike.

At tickover its intermittent sometimes its doing it, sometimes not! As previously said it is more prevelant when either reversing or crawling along in 1st gear.

It is the T180 Diesel 177bhp Rav4 (with Bridgestone BSR)

Thanks again.

If the dealer sorts it next week i will update the forum.

No its definatley not a rattle - when the clutch is pressed down it makes no difference. I can only think that it is something resonating somewhere.

Update- Its Sorted

I have got the Rav T180 back from the dealers yesterday after them having it for a few days. They found a turbo pipe "touching" one of the cross members. Whilst looking at the said pipe it was noted that it had a hairline crack in it. It has been replaced and is 100% cured!

Whilst it was there i mentioned that the clutch seems to have gone very stiff - Without any hesitation they diagnosed it as faulty and fitted a complete new clutch assembly. All this work has been carried out under warranty without any cost to me. I have even experienced getting 60mpg in the Yaris courtesy car! If anyone is in the area of Aylesbury and you own a Toyota you really ought to go and see the staff in the service department, they are one in a million.

I am well happy with them, Cheers Tony (workshop Foreman).

Thanks TGB too!

ps Rav is 2007 with 52k miles on.
