so, the largest portion of my oil control situation has arrived. a Moroso 20935 oil pan for the 3sgte application - it comes with a stud/nut kit too! i already have a Cometic gasket as well. i need to get some Gorilla glue, to bond it all together.
the benefit? increased oil capacity and LOTS of oil control.
the drawback? the cost ($350), oil changes go from 4 quarts up to 6 quarts, it is OBVIOUSLY non-factory (if ever inspected).
i've not even 'eyeballed' the fitment (per axles, etc), but from memory, it will clear without issue.
now i just need to order my 6 quarts of oil and super duper oil filter!
once all of this is done, i might actually be able to STEP ON THE GAS! oh heavens! what an idea!
the passenger side of the pan (nearest the timing belt) is flat near the oil pickup, but has baffling above.
the front, rear and drivers side (near the transmission) are all baffled inwards only - the doors only allow oil to flow into the collection area - not out.
if you'd like some detailed photos, i'll gladly take some and post them up.
3 photos of what i did to seal the Moroso oil pan. the rubber plug is a 3/4" cap, with a worm-gear style clamp to hold it in place - though i would prefer a factory 'spring' clamp instead.
the orange material is copper RTV. very high heat resistance and it creates a VERY strong seal.
the copper RTV was put on every surface, and on the threads of the 'union' (oil return plug) and gasket - but only enough to make a light coating of the threads, as i did not want a bunch of 'goopy' copper RTV on the inside of the pan.
the metal plug with the green cap is a factory piece that replaces the oil level sensor.
if anyone intends to get this pan, i will gladly supply the part numbers of each piece.
so, unless it is absolutely pouring rain this weekend, this will be installed this weekend - along with 6 quarts of AMSOil 10w30 oil and an AMSOil filter.
and the new oil pan has been installed along with a new Cometic oil pan gasket!
my educated guess was correct - the factory oil pan was sealed to the block with grey RTV only - no gasket. and that grey RTV leaked.
to be clear - after the engine was rebuilt (by a machinist) it was roughly 18 months before a single drop of oil was put into this engine.
beyond that, did some quick math. the factory oil pan held 3.5 quarts and .5 quart in the filter. so, the average 4 quart oil change.
with this moroso oil pan, it holds 6.5 quarts... and .5 quart in the oil filter... so, i am up to a 7 quart oil change! eesh! we'll see how it goes/feels after the bonding agent cures - then i can add the oil and started it up...
put on the new oil filter and filled the engine with oil (6 quarts at last check - will check again later).
fired up the Mr2, warmed it up in the driveway - then took it for a mad dash! it goes without saying that i was on it. not once during any of the hard cornering (left and right - always above 6000rpms) did the oil pressure ever drop!!!
i am soooooo happy that i bought this oil pan! i can finally drive my Mr2 like an asshole again!
i forgot to mention previously - when i installed the studs for the oil pan, i used blue thread locker as a precautionary measure.
the oil dip stick is popping out of its tube. i know that the PCV hose is pinched, but do not know if this would be the cause (or possible cause) of the oil dip stick popping out of its tube.
so... the next step is to install my fancy (ie. cheap) oil catch can, as this will allow the PCV pressure to be released back into the intake stream - minus any oil of course. if time allows this weekend, it will happen.
replaced the original PCV hose with one that was all of 2" longer - that removed the crimp in the hose.
took my Mr2 for a test drive just a bit ago... no more smoke at all, oil dip stick did not budge. the excess oil that did splash onto the FGK header is burning off.
also... the Gorilla Glue that i used to bond the Cometic Gasket to the block and oil pan is holding perfectly!
so... other than getting the reverse light working, replacing the muffler and getting the a/c functional - my Mr2 is done!
needless to say, i'll start daily driving it.
btw - if anyone wants info/photos of anything at all, please let me know. i am happy to share the knowledge.
oh... and the Moroso oil pan? words cannot describe how AWESOME it is! pushed through left & right handers - oil pressure never dropped once! i just kept getting the engine begging me 'more... MORE... MORE THROTTLE!!!'
+1 ^^ highly possible.. i would try to sort that pcv..
excess crankcase pressure a no goood.
im sure you know that
one would suspect... but this is the first time i've ever dealt with this issue... so, i was quite clueless. as of yet, it seems to have caused no issues.
my guess is that prior to putting on the Moroso oil pan, that the excess pressure was pushing out via the Grey RTV, hence the oil all around the block and oil pan during removal.
and when i put on the Cometic gasket and Moroso pan, the pressure could only escape via the dip stick tube. with that now sealed, and the PCV hose sorted... i've got a solid setup!
