    Hello,
    I have a '04 gen 2 Prius reading code p0016, P0420, and P1121. I know what the codes are for, I have a replacement pump already from a junkyard donor and was looking at possibly doing the same with the timing chain. I have been having some problems finding a parts list for the replacement, things like gaskets and possible pumps to replace while in the cover, or tools used. I was also looking for some general tips or info on what I'm getting into. I know this is a rather involved process but due to budget constraints, I am very poor, I'm looking at the most cost effective DIY possible.

    I received the car as a gift in '14 with the Odometer stopped at 299,999 I drove roughly 100 miles a day for 2-3 years and have doubled my commute sense then for the last year. I know that I put a hearty beating on my car, I've also noticed that it does burn some oil as I need to top it off every now and again. I have done some intense fixes before (Hybrid battery cell mostly). I'm just kinda hoping for some guidance in the " deep end" of the repair pool. If possible a repair manual PDF or download, video links, or step by step guides.

    Thank you

    My local library had several Gen2 Prius repair manuals to choose from... And while it was enjoyable to have a real physical book to look stuff up, it didn't come close to how good the answers are when doing a google search with keywords including Priuchat. It's the fastest way to figure out how to fix everything.

    Alright, so for anyone keeping up I went to picknpull today and found a fairly nice looking '08 that had a complete motor and dash panel. For those that don't know my MFD panel has been out for about 4 months now and I've been using and OBD2 app in my phone to keep track of everything; so I pulled the cluster with the panel still attached plan to install it in the near future.
    I did run into a few things that I wanted to see if I could get a tip on while pulling done parts.

    1. There is a large amount of wiring on top of the engine block and I couldn't find any type of clip on the donor so I just moved it around, is there a way to disconnect or do I have to just move it around?
    2. I've been having trouble finding the gasket kit for the timing belt cover at my local auto parts store, is there one or am I going to have to just lay down some silicone or similar substance?
    3. I'm anticipating this to be roughly a 2 day job and am planning on doing a as much as possible. I have the donor cars water pump, timing chain, chain tensioner, vibration dampener, chain slider, and camshaft timing gear. Besides the normal gasket kits is there anything else I need?

    I do appreciate all the help, and please let me know how not to break my car.

    The factory uses a substance. The repair manual shows how to apply it—size of bead, where it goes exactly, how much time you have to do it and complete reassembly.

    Thanks for telling about the factory substance, I have 2-3 days tops I have to do it on my weekend and it's my only car.

    Idk who is keeping up on this but, I have fine she's with the vvt solenoid change and it has head no effect but I did notice that the car does run a bit more smoothly.
    I have also changes out my instrument cluster to deal with the faulty combo meter.

    So to date the only things that I have done specifically for the P0016 is:
    A standard oil change with a full synthetic 5w-30 Castrol gtx magnetec and a fram oil filter
    A new vvt solenoid

    Any help would be fantastic.

    If there was a way, the manual linked above would likely mention it. I've always moved it to clean up the PVC, or get at the fuel rail.

    Please post here and let us know if you find the secret to this mystery.
    The manual may call for Toyota FIPG, but some have used other options with success.
    Did you inspect/clean the oil control valve filter during the recent VVT replacement?

    With those kind of miles (over 400k), a new timing chain and tensioner might be the best plan of attack. Here is an "advanced search" on DTC P0016, there are currently only 28 threads and likely one of them will offer some insight : https://priuschat.com/search/225658326/?q=p0016&t=post&o=relevance&g=1&c[node]=3+22+87+68+56+21+49+91+12+54+13+85+14

    One example with similar mileage : P0016 Code 2004 with 443,000 miles | PriusChat
