Engine & Gearbox / Re: Oil Buzzer after changing sump 😰
Last post by Ashton0678 -
So ive taken off the sump to inspect and it wll looks the same but what was a little strange was that when I tapped the grill inside it blipped a little and then leaked more oil so thinking maybe an air block of somesort?

Ps the cranking slows as if its struggling due to friction/resistance if that makes sense so decided to inspect.

Blue temp sensor is a good starting point. I would get one made by hella. Failing that check all the vacuum lines for cracks and the hoses from isv to the manifold and the crankcase breather including the rocker box bung to the inlet manifold.

No worries, unfortunately, I'm down south, so I don't know anyone up near you.
Might be an idea to put a shout on the FB page, it's much busier, someone may know a garage.

Thank you Monkey, I am based in the Midlands, in between Wolverhampton and Stafford.  The garage I have used are a specialist but I have zero confidence in taking it back there.

Hi all, I picked up back my mk2 which was left for at least 10 years in the garden. I have this car since 2009 and stopped using it in 2013. Got it back to drive, I can let you imagine all the work to be done on it :'(

Its a 91 fire and ice SB. I'm in France

Could be the blue temp sender.
It lets the car know when it's cold, to enrich the fuel etc.
Next time, try unplugging it when you're having issues.
If it does turn out to be it, don't buy a cheap one, there's a lot of dodgy pattern ones floating about on ebay.

Engine & Gearbox / Rough cold starts
Last post by JacksonBrownPants -
Hey,

Got a digifant 8v. Car was fine but in the past couple months has started to struggle to start. Often it starts and it's super rough, sounding almost like it's cammed, sometimes it's even so lumpy that it cuts out. Once it cuts, it really struggles to start again. Once it is running and has had a few moments for the revs to settle, it runs perfectly fine, and once it's hot will start again no problem.

There's nothing obvious. I'm going to clean the ISV out and see if that helps (checked and it's definitely still working), but if it doesn't i'm not sure where to start looking next. If anybody's got any ideas, i'd love to hear them.


TIA!

Hi and welcome!

Ok, there are two things that I would check, first being the compression.
I've had a mk2 16v before where it would start and run, but once up to temp, the compression dropped and had no real power.
I'd also struggle to restart the car. Genuinely hope it's not that one, as there's no cheap fix for it.

Second (and more likely) thing is that metering head:
The mk2 golf 16v runs on K-Jet, a mechanical form of fuel injection.
Essentially, it relies on incoming air lifting a flap (under the big black boot, above the air filter) that increases the fuel pressure being supplied to the injectors. When it works, it works well, but it needs to be set up correctly and from the sounds of it, the car runs well when warming up, which is when the warm up regulator is pushing more fuel into the inlet, but when the car comes up to temp, it shuts off and drops the fuel, leaning out the mixture. You could detect this by going to a garage with an exhaust gas analyser (any MOT station) and asking them to measure what's going on when it's running rough, if it's lean, that's your problem.

Now the compression can be done quite easily by yourself, if you're happy tinkering and have a compression tester.
The fuelling should really be done by someone who knows how to do it and has an exhaust gas analyser.
You don't mention where abouts you are, if you let us know a location, someone nearby may know for a good garage.
