Valve Cleaning DIY
For a long time, I've been plagued by a misfire on cylinder 4. I got new coils (twice) and swapped my cyl 3 and 4 plugs to see if it stayed on cyl 4 (which it did) and even ran a tank of Techron hoping it was a dirty injector. I broke down and ordered a new injector, which will hopefully fix my problem once and for all. While I was at it, I replaced my intercooler with the S3 intercooler (my IC had a little hole in it so it was time to replace it). The following is a documentation of how I did it. It's really long so it will be broken up into sections.
This was performed on a 2006 MKV GTI with about 67,000 miles on it, a BSH Competition catch can, noise pipe delete, and evil banjo bolt on the HPFP. I was winging it the whole way through this (neither APR's nor Stasis's instruction PDF documents would show the pictures on my Droid X for some reason that I'll have to look into, and it wasn't worth running back and forth to the computer), so there might be unnecessary steps. If there are, they didn't take long and I never ran into any real trouble, so who cares.
Before we start, here are some pictures of my valves before cleaning!
Cylinder 1:
Cylinder 2:
Cylinder 3:
Cylinder 4:
Now here's a picture of cylinder 1 after cleaning. I don't have pictures of the other cylinders after cleaning, but they all looked just like this. Pretty clean!
As you can see, things get worse from cylinder 1 to cylinder 4, just like staulkor reported seeing in his cleaning thread.
Ok, lets get the ball rolling with the DIY and stuff!
Things I used:
Torx bits (I used T25, T27, T30, and T40 I'm pretty sure)
M10 triple-square w/4" shaft length
M8 triple square
Ratchets, sockets, and extensions (10mm, 11mm, and 16mm for sure)
Flat head screw drivers (a really big papa bear one for prying, a baby one for prying in small places, and a normal one for undoing hose straps)
Injector re-seal kit(s)
A hose clamp (to pinch the fuel line)
Little foam ear plug (or similar plug for washer fluid line)
Berryman B-12 Chemtool
Wire brushes (I used rifle bore brushes)
A bowl (or something to put used Chemtool and sludge into)
Paper towels
Plastic baggie
Twist ties (like on loaves of bread)
Flash light
Pliers
Two (2) jackstands
Fancy hand pump thingy
Two (2) M10 x 1.5 x 120 bolts
Tape
