Judgement day

[Wellbs]

Evening all,

Coasting home tonight had a little spirited run for approx 30 seconds. Car develops a nasty rattle i think it’s the bottom end.

Oil changed last week belts done 4,000 miles ago. - i noticed when i started pulling it apart that ignition leads 1 & 4 were the wrong way round, could it of starved the cylinder, cause it to run lean and spin a bearing? (not a mechanic)

I don’t want to scap the car having speant almost £1,500 on it in the last year but if it is the bearings sounds like it’s goodnight

My mechanic mate is coming to have a look tomorrow or Saturday.

Thoughts, suggestions or prayers welcome.

Who changed the belts?
Got a video of the sound?

 

[MonkeyKnifeFight]

Did you change the dephaser? ?

 

[Wellbs]

Yeah all belts/dephaser changed approx 4k basically bought the kit from renault wolverhampton ago by a local specialist tbh i know he wasnt a garage but has done 3/4 previous with no problems ect

Will have to get a video tbh was too scared to run it

 

[MonkeyKnifeFight]

If your engine is toast ive got a bottom end you can buy. just putting it out there ?

Any way to tell bar pulling it apart? It still turns over and runs too is it the bottom end?

 

[Brigsy]

Ign leads wont have caused it, they can be on different cylinders without issue due to the wasted spark setup. Bottom end probably just knackered due to wear and tear, whats the mileage ? I would double check crank pulley or nothing on the aux side has fallen to bits

Nothing lasts forever though if its terminal, just bang another engine in.

As Brigsy said, leads being reversed would not be a problem, if it`s even possible due to the difference in the length of the leads.

No1 is the gearbox end by the way.

Used engines can still be had for the price of a decent set of tyres, so I would not condemn the car if indeed, the bottom end has failed.

Big end failure would be indicated if there is a rattle/knock on a light or trailing throttle, which stops under load.

Get a 2nd opinion.

seen plenty have timing slip not long after belts done.

I bought a Clio recently and driving it home noticed a nasty knocking sound. Worried to death I had the cambelt + dephaser changed but the sound persisted much to my dismay. Turned out to be the Carbon Cannister!

 

[Wellbs]

How can you tell if it’s the cannister/how did you fix it?

 

[Brigsy]

Carbon canister is more ticking not a heavy knock. Pull the plug on it temporarily to shut it up if needs be, will throw the eml on

 

[STEVE.M]

How can you tell if it’s the cannister/how did you fix it?

Disconnect the vacuum hose from the back of the inlet manifold & cap it.

CC sounds more like a single ticking tappet than a rattle tbh, and the noise will disappear in the general cacophony over 2k revs.

This way will not throw the EML light.

 

[Wellbs]

This one?

 

[Wellbs]

1st or 2nd?

 

[STEVE.M]

1st or 2nd?

Neither of them, 1st is brake servo & the one at the front is the acoustic valve.

Follow the pipe up over the RH ( UK drivers ) inner wing, it joins on in the middle at the back on a 182.

What's the benefit of blocking that up? Is it purely to reduce background noise?

 

[Wellbs]

Good news! The aux belt has worn causing the noise so an easy fix. The silver b*****d lives!

Thought the belts were changed 4k ago?

Still for sale @ £1k?

 

[Wellbs]

It was, guessing somethings flicked up and damaged it - wheel arch liners were removed before i bought the thing

 

[Wellbs]

Just in case anyone was interested - the soft cover for the aux pully had fould causing the belt to wear and partially snap - fixed in about 1.5 hours phew

 

[Wellbs]

Went up to Yorkshire this weekend about a 310 mile round trip, car was faultless tbh - just ticked out 100k and still returning 350miles + 50 left in tank and late 30’s mpg!

 

[ClioPowa]

Not bad at all, was that doing 60mph ?

 

[Wellbs]

Tbh i sat at 40ish the way up in traffic roadworks on the m45/m1 but was happy coasting at the speed limit on the way home
