Gaskets and Seals for R5 carb??

[spudmurphy]

Hi,

Need a bit of help with a renault 5 I’m running at the moment. It’s a 1.4 GTs with the c type (I think) engine, it looks like the turbo one, but without the turbo. My problem is with the carb, it’s the webber one with a primary and secondary throttle. I need to take it off and give it a general service and clean up and I’m guessing when I do this I’ll want to replace any of the gaskets I remove, so was wondering where would be good to get these gaskets?

Ideally I think I’ll at least need the gasket that goes between the carb and the inlet manifold, and the airbox and the carb, but if the carb somes apart then I’ll need any seals/gaskets there.

Any suggestions for suppliers is appreciated,

Spud

gaskets are normally fine to re-use.

You can get them but normally a week or 3 wait up here for them and silly money.

 

[spudmurphy]

Yeah I had a feeling they might be silly prices, especially if ordered from renault :roll:

Will have to take it off over the weekend and give it a clean. See if it will last more than 3 weeks between carb tunes :?

Alan, they're readily available from autofactors mate so you don't have to buy them from Renault. I was suprised to find my local place had a full headset available for my Gordini for £34 +vat

 

[Chris H]

I can't get any from any factor.

Can get headgasket sets no bother, can't get a carb kit without a wait.

 

[amdaman]

on the topic of gaskets, where do you get payen head gaskets from? I'm after one for the valver, or any high quality one for that matter!

:evil: :evil: :evil: :evil: :evil: :evil: God dammit I am beginning to dislike this car

Its a '89 1.4 GTS ren 5 with the weber carb on and I cant get it to idle or drive right at all. Stripped carb, didnt seem particularly dirty but cleaned, reassembled and refitted. Following Haynes manual I've tried to get the mixture right but it still runs like a bag of poo :?

Symptons are the same as before I stripped the carb, and a basic service (dizzy cap, rotor arm, fuel filter, air filter and oil filter) hasnt made a blind bit of difference. Symptoms are that it wont idle smoothly, seems to surge quite a bit, sometimes just completely die, usually when coming to a stop. With the car warmed up and no choke it will surge whilst driving, however applying a bit of choke seems to solve this but doesnt stop it idling all over the place.

Sounds like a fuelling problem maybe but where and why?

Please can someone help me?? cant make this work and dont know why :roll:

Thanks,

Spud

There is one thing I know about Carbs Al and that's not to mess about with them although I think i'm gonna have ot start playing myself soon.

Is there not an old boy where you live that can set it up for you for some smokes and a pint?

 

[Chris H]

have you changed the points and condesnor and set the timing?

 

[spudmurphy]

Chris, no points and condensor to change on this one, its got some snazzy little box to do all that work :lol:

Mick, wish there was someone in the area, but tuning a carb seems to be a dying art. Most of the 'engine tuners' I've spoken to can only run me a diagnostic on a renault as long as its injected :roll:

Have had another play with it tonight after speaking to a guy at work and something I've noticed is that turning the mix screw make little or no difference which I believe may be caused by either an airleak somewhere, or possibly some dirtin the carb :evil: so I'm hoping (if thats the right phrase) that its an air leak cos I've not tightened something up enough. Really dont want to find out that I've managed to not clean something :?

Another question though after playing with the car......... should the rotor arm/dizzy have any play in the shaft ?? This one does :?

On the upside I've managed to sort out two new tyres for the black 5 turbo alloys so they'll be going on when I manage to get it running right

 

[spudmurphy]

Still having issues with this and dont know what on earth is wrong with it

there seems to be an erratic misfire on it, every so often you can hear it miss an ignition event. The upshot of it is that the idle is crap and tuning it is difficult because I cant get it to run smoothly at all.

So far its had new plugs, dizzy cap, rotor arm, tappets all regapped and none of these seem to be making a difference it makes the car a pain in the ass to drive as it will die when coming to a stop and surges whilst driving.

Anyone got any ideas what might be wrong, and what should I be checking for?

checked all the vacum hoses?

 

[spudmurphy]

the only vacuum hoses on it are for the vac advance on the ignition module and the brake servo hose. Both appear to be in good nick. Have also stripped all the carb down to the manifold and reassembled with sealant to ensure no leaks between the carb and spacer, and the spacer and manifold. Upon restarting it though it still wont idle.

Is there any way of checking if a carb is goosed short of replacing it?

Anything else I should be checking?

isn't there also a crankcase vent pipe that feeds into the airbox? is this blocked as I have known this to make engines run uneven or idle low.

 

[spudmurphy]

Good call, it could be that. I have noticed tonight that if I take off the pipe that goes from the rocker cover to the bottom of the carb (post butterfly) and block it off the idle returns to normal. Currently the airbox is not attached and so the other pipe that would got from the rocker cover to the airbox (pre butterfly) so there would be no air drawn topside from the rocker cover. Would this be enough to upset the running? Also what is the purpose behind this setup? the prebutterfly pipe is much larger than the post one.

Cheers,

could be as the crank case vent will richen the mixture slightly, I can't remember what else this does, something like equalising the crank case pressure, Chris will know I just can't remember without looking in the manual that I no longer have

 

[Chris H]

the pre butterfly pipe is meant to get the most of the blow by from th4 crank out into the carb, the smaller pipes meant to only take some in at idle and other huigh vacuum times.

Is the bottem end funked? Breathing heavily?

The oils not been saturated with fuel has it?

Cheers Chris for the explanation of the breathers helps.

Funny you should mention the breathing though, just plugged both the breather pipes and its blown the dipstick out what does it all mean?

Car was free and owes me nothing, really dont want to be dropping another engine in it

Bottom end pressure, so most likely rings
