Sienna engine swap
2001 Toyota Sienna 145k miles
Did most of compression test, had trouble getting last two from back, ended up dropping my rachet back there. So in the morning I will maybe have to jack it up, and get under there.
How are these readings, they are a bit off. But higher not lower.
Well you certainly have uneven wear in that engine. You'd have to look up what Toyota specifies for normal compression on that engine but it looks like some cylinders are too high (carbon buildup) and some are too low (worn rings or valves).
I just took one plug out at a time, and put the tester in. And cranked it.
To do a proper compression test all plugs should be removed and the throttle plate opened up, then you crank with the tester in each cylinder in turn. Then put a teaspoon or so of oil in each cylinder and repeat. If compression increases significantly you have worn rings and/or cylinder bores. As @doc says a leakdown test would be a good idea as well.
Although I hate to judge before all the facts are in, it is beginning to look like you're beating a dead horse with this decades-old Sienna. It appears that the "dude" who sold it to you knew exactly what he was doing - getting more money than a junkyard would have given him for that poor worn-out old thing.
You can find 10 places online that will sell you a reman engine for this vehicle.
Number 3 is low compared to others. Did you also do set compression test?
So what is your question?
Can you just buy an engine for this van, or find a guy you knows how to properly rebuild the existing one? & what shape is the transmission in? Junkyard engines probably wont last too long.... and as far as finding the same engine but came in a different vehicle, that's not a full proof idea. Example being, my Camaro has a GM L36, a buick lesabre of the same year has an L36, but they have different intake systems, exhaust system, oil pan, and alot of other little details too.
Bought a Toyota Sienna 2003, 100k miles with a blown engine. Immaculate shape inside and out. $200
There's a big junkyard near by
They have no siennas for this generation but plenty other cars, wondering what year and modelw cars have same exact engines.
May just sell my 01 sienna, not the best shape, runs and drives. And pay my friend $500 to throw a used engine in it.
I have a 01 Toyota Sienna 145k mikes, bought for $800
So I recently posted a question, asking if my compression was good. And was told I did not do test correctly.
I just did the test correctly, took out all spark plugs. Did not do a wet test tho.
Here's the numbers
So a couple were maybe 168 or something but all were about 170 with number 3 being 150
Tested another Sienna, a 03 CE, 100k miles.
Compression test with all plugs out
170 150 170 170 170 170
How you think this is? Could it last 300k
