New Engine with Compression and Oil Issues
#2
first off is 100miles never is enough to seat in new rings. and that is what leaks above.
150 is on the low side and 175 is good but shows the rings leaking, big time cold. (cylinders not round)
did they bore it with hot block and cyclinder head plate simulator plate on top with full head bolts used and torqued, if not the cylinder will never be round , fully.
pcv white slime mean engine never run to full 180f and not run that way long time. (this dries out all water in the engine, )
if only driving 1 mile to work, there will be slime, and the need for more oil changes.
that ring gap looks wrong, did the guy with those pistons sell you 20over pistons with standard sized rings, if yes, and did you assemble the engine?
if they did maybe the guy there, ground the rings with is MIND thinking its 6liter V8, seen it,
the engine book is clear here, did you read it, in 1st link of first post on this forum (sticky to 96 fsm)
do not run wrong valve lash, there is never a reason to do that, unless using say crap, china, head gaskets, felpro is best. the cheap will shrink and make lash way too tight, avoid $5 head gaskets.
the one gasket not to cheap out on or front/rear crank seals.
the stagger is only for startup after engine runs the rings spin, naturally,
did you see the free 1996 Gm/tracker fsm book it overs ring gap.

i think ring gaps are wrong, or rings wrong size
then think bored as cold naked block, cheap and nasty bore job.
a cold engine, (new from suzuki) the bores go round perfect hot. not by accident but by clear design intent,
the head bolts distort the bore so that the engine must be hot and at full bolt torque, head off . to gain that perfect circle hot. bored hot.
see? there are lots of builders books that cover all this, and are very good.
