Oil remaining in pan after fully drained
I'm interested in adding the knowledge to the site, primarily for those prone to the intake failure.
When changing a oil pan gasket on my S2 SC motor I noticed there is still oil in the pan after it has been drained fully via the drain plug. Say about 1/3 of a quart.
Please post if your series motor, NA or SC and if you had oil left in the pan and approximately how much.
My interest is data only, please keep the fluff to a minimum.
Thoughts are that when a S2 NA has an intake failure, currently we tell them to drain their oil. The data I hope will not show that we should be suggesting they drain the oil and drop the oil pan to ensure complete fluid removal. And meanwhile I'm interested on the other motors as well.
Thanks

it should be known also the oil pickup screen will hold oil...also the oil filter is remote mounted so there will oil in the lines there...
to solve dropping the pan problem when the drain plug is removed, take a fresh quart of oil and pour it in....and then let it drain...also when replacing the upperintake and gaskets remove valve covers to ensure no contamants... This will be the best way to get all the contaminated out of the car......also it is recommended to change oil 100 miles after intake replacement
IF oil pan is removed BE SURE to fill oil fiter with oil to prevent bearing damage....because the oil pump will suck air before the vehicle has pressure.....ALSO remove connector on the ICM and spin engine over to ensure oil pressure

Just another curious point, is this remaining oil left there when the front of the car is raised up, say in a driveway? I'm curious as to how much would be left if the car were level on a hoist. :?:

Pat.. There is residual oil in the pan that exists BELOW the drain plug level. This has nothing to do with the pickup tube, or oil filter. It is simplly oil pan design. No idea what you were trying to get at with valve cover removal when doing intake gaskests.. The possibility for water to be in the bottom of the pan below the oil exists.
Repin, The plug is in the back of the pan and the car was on a very slight incline..I believe CorvetteCrazy'* was level on jackstands. Looking at the issue from the inside it is the design that leaves some residual oil in the bottom.
Scott...I know...I know.
