Hi guys
Just got my water pump replaced so did the cam belt at the same time. Problem is the engine is now vibrating quite a lot. I Can notice it at idle and gets more intense as RPM increases. It is bad enough that when im driving at 4000 RPM and higher the rear view mirror is blending 2 cars into one. Ha
Is this normal with a new belt and will it reduce as the belt slackens a bit???
Or do I take it back to the mechanic and say 'whats going on here'
Cheers,
Russ
call him ask if its normal. rather then driving back. im thinking its not timed properly or something like that.
i wouldnt drive it incase your causing damage
how the fuk did your mechanic think it was ok to return the car like that??
was it doing that when you picked it up?? looks like timming is out
i wonder if he will pay for the new valves....
tell ur mechanic to getfkd
sounds like it might be out a tooth or somethinig
no way should a belt slacken
or maybe he forgot the harmonic balancer
now how did he forget the harmonic ballancer?Quote:

maybe the harmonic balancer's on backward (i.e. doubled the vibrations instead of cancelled them out)
wait r u a mchanic? u can't possibly leave out the harmonic ballancer or let alone put it on backwards
not possible to leave off the harmonic balancer or put it on backwards....
Consider a engine mount might be too tight / broken / loose giving you this vibration. Maybe the rear engine mount is stuffed.
Is this vibration in gear while driving ? Or can you replicate it in neutral as the car sits stationary ?
backwards Harmonic balancer doubling vibrations. Hahahaha duuuude so so so many fails right there. Doubt you know what a crank pulley is??.
Anyways OP. Id say it is a loose engine mount or two, check passenger side torque mount and rear mount. Id say passenger side, how I know?? Left mine loose and got similar thing.
thats what i was thinkingQuote:

It only happened once the belt was replaced and im pretty sure they dont touch the engine mounts when doing a cambelt do they?
Its also a reasonably high frequency vibration too...
usually the last thing changed will be the cause of any problem, so check the timing, or get him to check it. and make sure he knows its his fault.
No worries, I will call and take it back tomorrow. He better sort that shit out!
LOL i'm dribbling shit guys sorry
what's all that shit about people removing balance shafts then? or are they different shit?
I shall not comment on the crank pulley remark, you're clearly out to insult my noob qualities. Not everybody has taken an engine apart/gone that deep
The balance shaft belt will be incorrectly timed. Has happened to me a couple of times
I think the harmonic balancer sits directly on the output shaft at the front of the engine (opposite to gearbox side, since a transverse is either left/right) its like a plate which has mass, then on the outside is like a rubber ring to absorb vibration, then on the outside of that is another ring which has the groove for the belt.Quote:

i read that its main design is to be heavy and absorb vibration to prevent resonance which would shatter the crank.

this is missing the rubber though. and the belt runs on the outer groove
BTW, I took it back to the mechanic after work today. He thinks its not the harmonic balancer as the vibration did not appear to be what you would expect from that. You also cant feel the vibration in the engine bay but climbing in the seat and then seems to resonate through the car. He it was not sure with out pulling it apart but said he would take care of it and sort it out on monday plus give me a loan car to drive for the day. I'm pretty happy he wasn't a dick about it too.
but the question is why did he return the car to you like that lol
Hopefully he will find out. Nice mechanic.
He said he test drove it before giving it back to me and the trip meter went for 4 and a bit kms after being reset.
Turn out the mechanic said that the harmonic balancer pin was in slightly bent, so that it was slightly out...hence vibration. Fixed it in a couple of hours once I took it in. I was pretty happy with the mechanics responce to it all. Also lent me a Mini Cooper S for the day, decent courtesy car me thinks..
Glad to hear it all went well
Goes to show
Something so small could have been deadly later on
At least the mechanic wasnt a dick about it and fixed it
Thats pretty nice, thought he would of given u a getz!!
