I can double check receipts, but ballpark ~$400-500 in parts and shop supplies if you only do the basics. The single cam chain tensioner is around $100, the FIPG sealant is $25 (one tube will do the front cover, valley coolant crossover, and - if you choose to - the cam tower), necessary seals and o-rings for the front cover and oil passages for VVT under the valve covers are ~$200, $60 in pink coolant, $60 for an oil change, and whatever you spend on shop supplies like rags, degreaser, red scotch brite pads, scrapers, and brake cleaner.

Without the extra goodies like motor mounts, crank pulley, and such, I think I was just north of $1000. But I purchased all four timing chains, all four tensioners, all four chain guides, extra FIPG sealant, and a few other things just in case I got in there and found other issues. I also did radiator hoses (just due to mileage) and a few other assorted hoses and clamps that needed attention.

Like most every other person has said who has DIY’d this job on the forum - the driver side chain tensioner is most usually the only part that really needs to be replaced; chain guides were nearly impeccable and chains looked great.

Some recommended ‘while your in there’ items I’d think about doing if you have some miles on the vehicle are the water pump, serpentine tensioner and idler, and serpentine belt. Plugs, too, if you’re close to mileage. But if those are in good shape you don’t really need to replace them. Up to you.

From time to time some online Toyota parts dealers will have a sale on parts. Right now, Fred Anderson Toyota and Toyota of Decatur are 25% off plus free shipping. I purchased most of the parts the last time they were on sale to save a few bucks. Genuine parts at a discount.
