K20Z3 Teardown

here's how to disassemble a k20z3 engine.

Why do this ?
valve replacement
cam install
k20a2 oil pump installation
ARP rod bolt installation
bearing inspection
blown head gasket
timing chain replacement
those are just a few

assuming the valve cover is already uninstalled, this is how to do it.



50mm crank pulley removal key is needed, along with 19mm socket. long breaker bars are needed as this thing is torqued down real tight.



14mm socket to remove 4 timing cover mount bolts



10mm socket to remove timing cover bolts, there are 3 that go from the oil pan into the cover and the rest are forward facing

pry cover off


here's what we're looking at now, the timing components


remove cam pulsar plate by hand


pull back on chain tensioner guide(guide on the left) and put pin into timing chain tensioner hole, remove 2 10mm bolts on TCT and remove the TCT. Remove 3 10mm bolt on chain guide and remove chain guide(guide on the right)



loosen 2 cam tower bolts with 12mm socket and remove chain cover


pull of the timing chain


loosen cam cap bolts with 12mm socket

use this sequence for proper loosening sequence


loosen 2 10mm bolts on rocker assembly on cyl # 4 side (flywheel side)


lift off rocker assembly, careful as it will push to separate keep a firm grip until you place it down in a secure area


cylinder head removal


remove lost motion springs and set aside(preferably near rocker assembly)


loosen and remove 10 head bolts, the socket I used was a 9/16th star socket.

use this sequence to avoid warpage


place cylinder head aside in secure area


now we see some pistons, I sprayed mine with wd40 to clean off the carbon buildup hence the weird look.


remove 2 14mm bolts and remove ac compressor bracket from oil pan


spin motor around on engine stand


loosen and remove 10mm bolts holding the oil pan onto the block, off memory there are 22 of them


big flat head screwdriver and pry off the pan, there are 2 wedges to do this 1 on each side. do this carefully to break the seal then lift it off



loosen and remove 3 10mm bolts and remove the oil chain tensioner.



loosen 2 14mm and 2 12mm bolts from the oil pump, lift and move oil pump until you're able to remove the oil pump chain.



remove oil pump

short block after cleaning


and all the parts that we just removed.

true, you don't need torque specs for tear downs though. you need actual torque LOL the damned bolts are tight.

yaaaaa but once they remove the parts, they willll have to put it back together. most of these kids dont even know that they need varying torque for bolts.

but all in all i love this thread, *bookmarked*

and PS why are all the 8thgen Si enthusiasts everywhere BUT nor cal?
