ike PO didn't put RTV all the way around the sensor hole.
really the RTV is the total gasket, and must be perfect or it will leak badly. (in the factory the block was pressure tested, after the RTV cure.)
harboruz freight has the gauge for 20 bucks. with the free suzuki hose.

connected up. to Harbor "FRIGHT" (sic)
"rear main blown? (seal?) i bet it not.
all suzukis leak valve cover gaskets, after 60k miles, the gasket and lash steps skipped (par for course) so it leaks,
then the distrib seals leak down the bell to the bell vent then to the back of block and down past rear seal, fooling everyone but me.... its not the seal I bet.
the suzuki main seal is one of the best setups of all, a real mount and full seal. (no funky split seals or other wild stuff like oil slingers... etc)
I would clean maf with CRC maf cleaner from 1foot distance, never close with powerful spray there, i soak it first , rest like 3min the hit it from afar.
the maf is $1000 at suzuki ,you are lucky to have spare, or $300 at cardone rebuilt.
any cracks in the INDUCTION system end to end, will (may) cause engine to go lean.
the engine does not run closed loop at WOT. so the MAF rules the roost accelerating and the O2 is off line. then.
so any air that sucks into the the engine, (un-metered) will cause lean, accelerating. worse at low speeds, and gentle accelerations
but fuel pressure is #1, the ecu ASSUMES its at spec, and cant measure it so injects blindly on this fact. (and the FPR raises pressure at WOT) so that must happen too.
i fuel pressure is good, at idle and wot.
then we work , unmetered air.
a dirty maf is also unmetered air, as the crud there causes it to read low. all the time.
at idle the 02 sensor is online and corrects this error. (hides it)
