QLD: Noisy rattling MK2 engine / Intro into the MK2 scene.

[Salkow]

I'm back up and running!
kind of……… Having a few issues with the idle game as well engine mounts are 100% shot and seeming to cause the engine to be skewed and it appears the down pipe is almost/is resting on the front sway bar. Anyone have some spares? Otherwise vwheritage will be getting my business.
Now I'm wondering if anyone out in this great community has a spare or knows where to go to for an O2/Lambda sensor? Have found a few on Ebay and quite exxy in price. It's being a bit temperamental on start up cold and when coming to a stop it briefly cuts out a bit. I have the blue temp sensor on its way and the other thing could be the idle control valve? But they seem to be quite expensive too!

Gave it a good clean and the gross under bonnet mess is now gone after a whole lot of cut and polish
Hopefully going to lower a bit more soon, so damn keen to get it to 100%!

Try cleaning your ISV/ICV (Idle control valve) they can get dirty.
Then follow this thread.

Whenever my MK2 goes full retard (every year or two) i just do the above things and then its all sweet.

Camden GTI have a MK2 they are wrecking (02) 4627 3072. Another source of parts is GTI Imports (02) 9653 1114

Both are in Sydney.

Thanks guys! Seriously the best help this forum!

[sports racer]

That's only because you've got a white MK2. If it was black we'd keep telling you to fix it.

Just joking Locky. Honest.

[Salkow]

Haha! Yeah white is always my go to.

Bit more progress has been made. Bought a whole lot of cleaning stuff and cleaned the ICV and MAF. So far running pretty well only thing being still a little wobbly on cold start. Idles great but just dies out with the battery light being a bit illuminated. So thinking the alternator could be on the way out or have read the brushes in it?
Anyways have also cleaned up the gross mess which was on the underside of the hood and put in a new blue temp sender and a ram air intake which i nabbed off Ebay for $30. Spruces engine up a little bit and makes it sound a bit better, definitely no performance enhancement was in mind for it haha
Lowered the rear a further 10mm just to try eliminate that tyre gap, has come up looking great! Just have to embrace some scrub.

Heres some photo's so enjoy, the more i look at this thing the more i love it.

Looking good mate! I seriously love those wheels on your car! Stance is good too.

To check the alternator just throw a multimeter on the battery terminals when the car's running.
Should be around 13.5volts (ish).
The regulator/brushes are easily replaceable (2 screws) comes out as one piece.
Replace the blue temp sensor yet?

Yep have replaced the blue temp sender and still notice my flashing coolant light comes on even though its running what appears to be very cool? Does not go past the second bar on the gauge.
Have checked the alternator voltage and pretty sure thats what it shows. I will check again and post what i find though.
Being a little bit confusing thats for sure.. Leaning towards maybe biting the bullet and getting a new ICV though being $200+..

Mate, it took me a couple of years and a whole lot of coolant to realise it was under dash earth for clocks. The coolant light circuit is on the clocks and the voltage drop of the bad earth triggers the coolant light. I could be wrong, but if your clocks seem dim at night and fluctuatge, then its the same issue as mine, Mk2 90, Alpine white

Check the hex bolt clamping the steering column is tight and theres a ground point on the drivers side pillar nd a earth buss under the dash that you should check connections

Okay i might have a look around today as I'm not at work currently. I don't think my dash seems to dim or fluctuate during the evening with lights on but i certainly know the MFA display does not work. The little LCD screen is blank all the time.
Thanks for that though and i will keep posted.

Bit of a further update.

Cars been running great except still those cold starts being quite harsh and juddering.
Still narrowing down to the ICV which hopefully I can locate one soon.
Took it out for a big burn on the weekend and came home to find the front coolant flange was leaking from the lower bung/plug.
Tried retrofitting some stuff to sort out leak but didn't work.. Now have siliconed the bung and will see if that can hold up for a bit.
Need to do a bit of a order for new parts such as engine mounts and possibly these flanges and new O rings for them.
Bugs me to because I just poured a whole heap of new coolant in after the 500kms of running on water to bed the head gasket! [emoji20][emoji20][emoji20]

Also still cannot for the life of me work out the coolant light flashing.. Have sprayed almost every grounding and elec contact with contact cleaner but no change. Hmmmmm!

I just changed the coolant flange on mine. You can buy them brand new from the Dealership. Only cost me $50 including all the o-rings.

try disconnecting the coolant sensor from reservoir. then short it to prevent open circuit and ensure it is the coolant level

it could be just overheating.. see water pump/thermostat/fan
