where to find and how to install engine

this is regarding the 98-00 sienna xle

I have a 98 Sienna XLE with 198,000 miles on it. Although I'm pretty sure it'll get me another 100K miles I'd rather be safe then sorry.

I've searched all over the internet for a 98-00 Sienna engine but I can't find one. Where can I find a low mileaged engine?

What items would I have to purchase alongside the engine to complete the engine swap.

And I want to do this at home so does anybody know how to do the engine swap or have any readings for it?

Out of curiousity, how much would a typical shop charge for this kind of engine swap?

Thanks in advance.

Try ATK, VERY reputable supplier of used and reman engines.. did you say 198,000 miles.. did you have the sludge problem?? just bouught a 1999 xle with 72000, sludged bad.. luckily i ( my mechanic friend) spotted it I used amsoil oil flush and scraped out the oilpan. put in marvel mystery oil and will do some 1000 mile oilchanges for a while..
