      Hey G60ing, should I removed the head and send it to be machined? I have the bare block on the hoist rn the chains should be here by Tuesday. Iím just wondering if i should stop being a ***** and pull the head! I did notice tons of carbon and I donít want to hit only the intake side with cleaners and still have a bunch of carbon on the exhaust side. Or is there another way of getting the carbon off without head removal?

      Better ask Paul. I'm torn on this subject. You can get the carbon out with a walnut blaster without having to pull the head.

      The head is fairly complicated and I there is so many potential areas somebody could screw something up. Decking is good but it changes the timing, that said you are installing a spacer, that too will mess with the timing.

      I can't help you other than say chose wisely.

      If you were doing port injection the fuel would clean the carbon out.

      Iíve removed a 2 liter fsi head many times, my trick is buying 5 different colors of nail polish to mark the teeth of things that are in time and take a picture. Only works if it was in time before plus I also have a copy of the Bentley manual. Iím just truly scared because this is my daily and Iíve never worked on a VR before... Iíve already gone 3 weeks without a car killing my pockets because me and gf have to carpool in this terrible Seattle traffic! Iím into the loan for 1 more year and I donít want another loan. Iím at 154k miles bought last year at 89k Miles. I want to be able to get 250k out of this block and trans before I purchase a new daily! Idk who Paul is whatís his handle or username?

      Hi!

      I have run a few different junkyard heads and motors and a few gallons of fuel port injected clean them right up. My current ports are shiny after just a day running methanol.

      I would leave the head and media blast it. Dry ice works best but hard to rent. Lots of folks have walnut you can borrow.

      What about water meth??? I read a thread about water meth cleaning the inside of the block within a day of use?

      If its port injected it may work. It really depends on how caked on it is.

      The details of how to time the engine are in the first post.

      Also not mentioned the O-rings that are in the housing of where cam sensors sit need to be replaced. I took that cover off and found metal shavings. There are 6 of them @ $.86 a pop you have the engine out if it needs replacing.. replace it!

      careful on the oil pump, I believe (its been a little while) that there is a circle with an arrow that should be pointed to the 12 o'clock position.

      Also less important but good to verify is the crank gear has an angled tooth that should point to the split seam of the main cap.

      Did you lock the cams?

      Did you lock the fuel pump? (looks correct)

      My friendís 2011 3.6 CC suffered some severe issues due to screen being pushed through and into the cam phasers. One phaser was locked up. Talk about EXPENSIVE. I probably would have just bought a low mile motor it was so so expensive to replace them. 125k miles

      He only had one code: 000020 - Bank 1: Camshaft B (Exhaust)
      P0014 - 004 - Retard Setpoint not Reached (Over-Advanced) - MIL ON

      Guides were worn pretty good. Upper chain was stretched to the point of having slack when motor was at TDC.






      The carbon buildup wasnít bad at 125k miles:

      Any interest in taking the phaser apart to see if it could be repaired? I know the intake and old exhaust ones come apart pretty easily.

      He is in Colorado. Iíll ping him and see.

      The screen has been a known potential issue.

      Oh yeah. Always down to see what failed and confirm it.

      Oil changes done every 5k pretty religiously. I drive the car hard, I maintain it appropriately.

      Youíve clearly never worked on many VRs. Chain stretch has always been an issue. For the mileage and how hard the car is driven Iíd say the guide wear is pretty normal.

      Head was clean inside as I expected. No other signs of wear or slowing down.

      Donít you have some FSI fueling to 750hp to figure out?

      Definitely a good sized hole in that filter. As Iím sure you were thinking when I sent you the message on FB.

      Confirmed screen bits in the exhaust adjuster. Intake cam adjuster didnít show any abnormal wear at all.










      Now onto the fun pics


      Scoring can be seen on the internal wheel. Just the one lobe of it though.


      Other lobes looked like this:

      And of course my helper...
