What are some surefire signs of an intake leak, and what can be done to prevent them.... I don't believe I have a leak, I'm just trying to stay 1 UP on potential problems.  | ||

Spray WD40 around the intake manifold while she's runnin'. If you hear a change in idle, you've got a leak. | ||

nuthin to do to prevent them leaking eventually(the seals are not life-long, and will deteriorate) . . . test em if your got a problem, leave em alone if ya don't, and follow the specs, and go slow when replacing them -- easy to cause problems if you rush the install | ||

I've been wondering about this ... I wouldnt want to use wd40 because the area is tough to clean. wd40 leaves a greasy film that will burn up kinda smelly etc. I have a can of stuff to clean off oil and other grease off of brake discs and the engine. This stuff is flamable. Spray it onto something and in no time it will disappear completely. The can doesn't tell me what it is, but I wonder if I could use that to search for intake leaks since it leaves nothing behind. | ||

Brake cleaner will take off paint as well (don't ask ...), so maybe not a good choice  . Water mist will affect idle as well (make RPM drop AFAIR.) Henrik | ||

Well the repair manual says to make a nozzle with a copper tube, attach it to a propane tank, and use that. | ||

Also if you notice you idle changing. That happened to me. I stopped at alight and noticed that the idle was high, I adjusted it, the next light it was low, I adjusted it, next light it was high, etc.... | ||

Use a bernz-o-matic. It is one of those small propane torches you can get from Home Depot. Turn the propane on but don't light it. then work around the intake. Now if you hear a change in idle you found your leak. No mess, no paint eating, and no fluids in your engine. | ||

Propane; great! Thanks for the tip. Henrik | ||

Where is the intake manifold??? Can I get to it w/o removing any parts? | ||

What I did on my old S3 was while it was cold, I started it up and placed a hand on each of the header pipes, you will know which cyclinder has the leak as one header will be bearable to touch and the other will be untouchable! Simple but it works! Cheers Jodie |
