[Mk2] [Turbo] DIY methods of testing for Vacuum leak

Post by killerferret666 »

What it says really, what success have people had?

After changing lambda and checking over water temp sensor and both now ok and good, i think im left with either

1) vacuum leak - possible as idling about 1000rpm now

2) ECU repair just didnt repair it

Id prefer option 1 but need to find a way to test it.

Blow smoke from a fag into the system.
Worked for me to see a loose nut between turbo/manifold.

Used fag smoke for side of the road testing. Tend to use a cheap smoke machine now, just waft it around the engine bay and you can see the smoke get sucked into the leak.

Cost about £25 on ebay years ago
