I've just noticed that one of the bolts that holds the IACV to the plenum is missing (top one on the battery side). Does anyone have a spare that they could measure the length of? If not, I'll see if I can take another bolt out after work tomorrow and measure.
Measurements Well, it didn't happen until last night, but I pulled one of the other bolts out to measure. For anyone else that might be interested: Total length (inc head): ~39mm Bold head: ~4.2mm Thread: ~21mm Un-threaded section: ~13.8mm Small washer: ~1.27mm Large washer: ~1mm
