Trouble starting & Horrible  wining noise.


Recommended Posts

I set the tappets today and did a bit of cosmetics in the car interior for the weekend.

I tried to start the car and again flattened the battery and then the battery pack.

 

I have no idea what is up, it will only start with the use of jump leads. So I started the car with the assistance of a modern motor and a set of jump leads, and she runs.

 

It turns over and you can hear it catching and then it just keeps turning before finally starting, I put the old ignition system on and it again has trouble starting (so not megajolt).

 

When it runs its is fine it will run in every gear and has no loss of power.

 

BUT there is a horrible wining noise, it sounds like a dry bearing but not if you know what I mean?? It is coming from the carb side and goes a little quieter when you press down on the carbs?

 

I know the sound is not the alternator or waterpump, or fan belt!

 

Any suggestions on the noise or the starting problem.

If you press down and it goes quieter makes me think you have a vacuum leak somewhere.

Especially with the hard starting.

 

Does the noise correspond with rpm, so if you rev it does the noise go with it?

Could you make a video of it?

Mmm - sounds like a classic inlet manifold gasket leak to me. First time I had that, I couldn't believe the noise it made!

 

It was as simple as tightening up the nuts and lugs to get rid of it - and changing gaskets if that fails. That it changes if you lift the carbs is a big giveaway.

Presumably it was running ok before you took the rocker cover off to set the tappets.  You will have had to remove the breather pipe to do this so maybe it is something in the breather system that has come adrift and is causing the air leak?

All, Fanks!! sorted with a new manifold gasket and re-fit of the manifolds. With a carb tool from Steve (gt6steve)? I think he is called on here? The car is running sweetly ready for the weekend ;D

 

Realworld, as you said, I should have known, the manifolds have been pff loads of times with the same gasket re-used! I should have checked the gasket but wanted the bits on as I was fed up with taking the lot apart again! Thanks

Thanks again

Rob
