more help and photos, more things you will find of interest now or later. anytime.
first just images in gallery j18
https://fixkick.com/forum/ezgallery.php?...ery&cat=15
then my pdf I made
36 pages, j18 or j20 are same mostly. we have j20 running in J18 car sport, not me but others, so now you know parts are there too. Crank not the same)
j20 is a stroked 18. and vast parts shared.
https://fixkick.com/engine/18L/random.pdf
the J18 is great engine and has lots of power, unlike G16
J18, is not free running, so do not spin the crank with chains off, ok?
most times just and eyeball finds the huge clues, for sure green AF leaks in all places possible side and outside the engine,
my guess PO ran the engine on water only and warped the head but I do hope BIG TIME I am wrong.
!
the next lowest cost tool is compression tool , free rent, or even from harbor fright at $20 owned. (most head warps cause cyl 2 to leak into #3, making both fail leakdown and compression) 199PSI hot or warm,. WOT this engine has higher CR compression ratio and makes lots more power that way and the 200cc more displacement.
