    Depending on the experience of the supporting hands, 4 hours is doable;).

    But at the labor rates round here, that’s around $500-$600:cool:.

    Watch the videos, DIY and buy something nice for yourself or others around the holidays(y).

    Sure would be nice to do the intake, pcv and catch can at the same time. Wouldn't have to go back in there for a long time.

    Yes, getting professional mechanics, albeit inexperienced at doing this, to do a good job, might be an exercise in frustration. Save the agro: if at all possible, DIY is the way to go.

    You can get the PCV hose off, for installation of an Oil Catch Can, without removing the intake manifold, but it's definitely a lot easier with it off. I did my install with the IM off, and it would have been impossible otherwise, but that was mounting the OCC on the lower cross beam, below the intake manifold.

    But a couple of times later I've unhooked and extracted the OCC, to mod some hose clamps and/or to clean it out.. It's especially hard to reach the end of the hose connecting to the PCV, just barely doable.

    I typically access it from below for draining, during oil changes. My OCC has a bottom drain, works well thus:

    hi Mendel,
    Thanks so much for your EGR posts on here.
    Terrible knocking and rattling on start up and running yesterday produced PO 300, 301, and 303 codes on OBD. Check engine light came on briefly over the summer produced EGR code but then went away and life got in the way.
    Sounds like EGR is the likely culprit based on what I’m reading here … it is a 2010 Prius with 150k miles bought used a few years ago.
    will be following your posts as I remove and clean the EGR and cooler in Vancouver this weekend.
    Joe

    Is coolant level normal? Has it dropped?

    Yeah EGR the culprit, and head gasket failure the crime. I’d make the head gasket assessment first priority. Boroscope inspection of the combustion chambers, morning after a day with driving, would be best time to see coolant evidence.

    To get the spark plugs out, video #13 here is good (contrary to video, plug torque spec is 15 ft/lb with clean/dry threads.
