Matt Danger's B5 S4 Owner Log

Started it up Thursday night and immediately realized I’d forgotten to tighten the passenger side manifold. Then, after that was tightened down it would no longer start.

It refused to start again on Friday.

However, on Saturday it started first crank but I had 3 problems:

1. CEL for p1340 camshaft (g40) and crankshaft position sensor (g28) with incorrect correlation code.

This was caused by my passenger side intake cam being off 1 tooth. I suspected this cam was off because when I assembled the heads I was careful to get the cams timed correctly but once I installed the head in the car I thought the cam was off 1 tooth so I moved the cam back a tooth. This was unnecessary and caused my CEL. I moved the cam forward a tooth, bringing it back to its original correct position and that resolved the issue.

I later realized that when the cam chain tensioner is compressed the cams alignment marks may not align correctly with the arrows on the caps. You are supposed to be able to count 15 chain pins between timing marks but this is sometimes difficult.

2. Low oil pressure switch light would illuminate when revving past 2,000 RPMs

This was simply a broken wire in the harness behind the driver side head. My poor harness is getting pretty beat up from age and the several engine removals. I’ve had a few other harnesses laying around from other cars and they each had their own problems. I may build my own harness in the future to fix some of these problems and make the engine bay a little cleaner.

3. The 034 fuel pressure regulator housing was leaking from the small vacuum fitting plugs.

These plugs don’t have any o-rings or anything but wrapping some teflon tape on the threads sealed up the leaks.
