I have a b20b turbo. I recently changed the oil. drained all the oil, and removed the filter. I had 4 quarts of new oil total. I put some in the filter to prime it. them put the rest in the engine. I thought b20s took 4 quarts but my dipstick reads half a quart over the top dot. Thats when the car sits overnight. but when warm it reads a little under the 2nd dot.

whats going on?

 

all the oil is settling to the pan when it sits overnight? I would think.

 

thats what i thought. but dont you check the oil when it sits over night? ive heard so many different theories on this. i let the pan drain all the drips for like 35 minutes. and put only 4 quarts in

 

if its only a tiny bit over, it's not a big deal.

 

half a quart? maybe a little less

 

it'll be fine. Just gives you more time before you have to check it again. If you notice performance decrease or wierd noises for some odd reason, drain a little out.

 

anybody else have input?

 

if the drain back on the filter is not working it could be that

 

but why would the oil level read high?

 

myn reads high when cold but thats due to an oil cooler after start up it returns to normal

the only reasons i can think of ...
not all oil drain out when you changed it
oil filter capacity is draining back when cold
