Yes, if you unbolt the cam subassembly from the head, the cams come up together as well. But you'll need to clean and reseal the cam subassembly to the head during installation. Perhaps that's a step they wanted to avoid?

I know what the original service manual says. I am trying to understand what the recall instructions are asking for. Do the “new” instructions ask for A or B: A: remove the cam caps and leave the subassembly bolted to the head. B: unbolt the subassembly from the head As I said before, option A would save hours of time because it avoids most of the packing seal but risks head warping. Option B is what the original manual tells you to do. |

Some insider information. In Japan the work will not be done at the dealers place as in normal recalls, but in 8 service factory centers nationwide (2 places in Gunma prefecture, Tokyo, Iwate, Tochigi, Aichi, Shiga, Ehime ). The recalled vehicles will be transported from the dealer to the service factories for the work. Therefore it'll cost about one week per vehicle.

You'd want them to transport your vehicle on a carrier to a facility and then back to you after doing the recall work? I say no thanks, I'll keep it close to me where I can be assured dopes other than the ones close to me aren't handling it. Much easier to go after someone for unsavory practice in person than remotely if it came to that

About the cam caps vs carrier housing: The service manual indicates Quote:
Quote:
- It's already contradicting itself. - A cylinder head stands little chance of getting warped by the flimsy lower cam housing should the upper housing the removed in place: the head is still bolted to the block - The upper camshaft housing will undergo the same stress, should it be separated on or away from the engine: I'll flop around just as much. - The lower camshaft housing has more chance of remaining straight if it stays bolted to the already flat and stiff cylinder head that's already bolted to the flat and stiff crankcase. |

I agree with you on this point. The wording is a little confusing. I think they were talking about the heads though. My logic is that there is no such thing as a "cylinder head sub-assembly" on this car. There is a head and a "camshaft" housing sub-assembly. Quote:
No it doesn't because the springs are not in the picture once the subassembly is removed. Last edited by ermax; 12-26-2018 at 09:16 AM. |

Since it's 2 cylinders per bank, there's a "zero lift range" where the valve springs are completely unloaded, it's easy to have the whole valvetrain unstressed for disassembly on the engine. |

I really doubt they're unloaded at any point in time. That would make for a very rattly valvetrain. |
