SL55/63/65/R230 AMG: M156 Intake Manifold R&R in R230 Play by Play



Some observations and differences.
In the video he discusses there being 11 intake manifold aluminum bolts but can only find 10. I found 10, removed 10 and it came out fine.
The rear hose removal at min.7:40 is not on my car. Anyone know what this is for? My SL63 just has a plug in there.
Also I purchase a NIB Intake Manifold from Mercedes a few weeks ago and surprise surprise the PCV hole is not threaded...looks like I need to tap it.
I did find that injector #8 came apart when I was removing the plug, as the plug on the injector itself was broken.
I also broke one of the shell's on the throttlebody plug on the front of the manifold. Which sucks as it will require the shell and female plug to be replaced. I can get it running today, but the pins will have to be removed and then installed in a new plug.
Up next is finishing the PCV/Catch Can and vacuuming out the engine valley before I start reinstallation.
More updates to come.
Full List of items being replace:
- Intake Manifold
- PCV
- Catch Catch (PLM Kit with Radium Engineering Can)
- Coils
- Plugs
- Injectors
- FPR
- Fuel Cap
- Fuel Pump
- Fuel Filter
- ABC Filter
- ABC Secondary Filter
- ABC Flush
