I tapped the oil pan on a Miata at the very lowest point in the pan over a year ago and its still kicking. Thats actually where the company says to install the return.

The Greddy turbo kit for the 2006 Honda Civic SI uses the stock drain plug location for the oil return line. The drain plug is replaced by a Bonjo Bolt to which the turbo drain line is connected.

Already tested, and proven to work OK.

I think most the problems with having the oil drain below the oil level is on tired engines with a good amount of blowby. My old 2.3 was frick'n tired and would push oil out the dipstick on hard runs if I didn't cap it off. I'm sure if I had the oil drain below the oil level in the pan it would never drain good enough. To much pressure pushing against the surface area of the oil.

test this with 15w 50 mobile 1 synthetic. Please that is only water, there are different viscosity between water and synthetic oil. :6

Im not saying the same theory does not apply i would assume there would be some kind of delay though.

good point

This principle only work if the pressure on both liquids is the same.

I should make a quad -12 line kit for venting your oil pan. I could sell it on HT, and pretty soon everyones bling machine would have 8 catch cans. :S

I said that this principle only works with same pressure. I didnt talk about how it is in an engine.

The Greddy kit for the RX8 also runs the drain through a banjo-bolt in the stock oil drain plug location. You don't get much lower than that.

ahhhhhh hahaahahahaahahhahahahhhahahaaahhahhahahhaahahaha


tell them that they need to T the drain line to their compressor inlet. that will provide the syphon action needed to get the sweet oil drain action going!

Re: Honda Myth: Tapping oil pan at bottom is bad.
 
Interesting. I take it that the pump is pumping the oil through the engine as fast as the oil drains through the turbo? I guess the level in the oild drain pipe will never get any higher than the level in the pan? Please explain, all the "turbo books" say otherwise but I have an open mind and lots of respect for the hands on approach.

Don't forget oil flowing to the main bearings, cam bearings, (oil cooler). So it's not like you have to account for 100% of the oil coming down the turbo drain, only a fraction of it.

Gravity will keep the two levels the same.

Thanks,
ok,

I see, the same amount of oil being diverted to the turbo comes back at the same proportion. I guess a long drain tube gives a margin of error when going down hills, ect. right?

Only if the two fluids are of equal density.

Re: Honda Myth: Tapping oil pan at bottom is bad.
 
we've tapped ls1 pans low, used the oil level sender hole too. All caused smoking issues and seals leaking due to drain issues. No matter the size. gravity feed above oil line with no weight holding the oil in the drain works best.

Atleast thats for us LS1 guys with gravity drain.

Re: Honda Myth: Tapping oil pan at bottom is bad.
 
i agree that having a return above the oil level in the pan would be ideal, but stevemode makes a great point. i personally think where everyone has the problem is with (as mentioned above) blowby. i'm willing to bet that with most returns that are above the oil level in the pan, the return never gets completely full. let me say that another way, anywhere along the length of the return line, there will be 'air' in the line and never a full cross section full of oil. therefore, positive crank case pressure would never keep oil from draining into the pan.

however, if the return was lower than the oil level in the pan, any positive pressure on the top side of the oil would potentially be fighting gravity for any oil in the return line. this would be due to the fact that if the return is lower than the oil level, it will always have oil 'blocking' off the line. as long as there is a good PCV setup, i don't see where this would be a big problem.

Re: Honda Myth: Tapping oil pan at bottom is bad.
 
some one correct me if im wrong
lets say you have 60 psi oil pressure going to the turbo at WOT
oil goes through the bearing ect and come out to the drain
makes sense to me that some of that pressure (less) transfers in to the drain (to make thins simple say 1/6)
so there is 10 psi pushing the oil down through the return line at a decent speed (60 psi coming in and the volume has to go some where)

so if the return line isn't supper short and you got a decent catch can set up you should be fine

was there a question in there?

Re: Honda Myth: Tapping oil pan at bottom is bad.
 
I'd try this with my EG, but the current 16 inches of mostly vertical 5/8" drain line would fudge any problems that may pop up :8 I'd just get a ------- scavenge pump and do it that way. At least you'd never have issues, and can always sell the oil pan easily if you blow your ---- up.

My EF kit with the HF-A/C adapter I made put the drain line very low, maybe right at the oil level. There is all of 1" from CHRA flange to top of oil pan, and to make things worse, the 3" DP below. It comes out the driver's side, whitey bends around, then crosses over under the drain line. With 2 different old turbos on it, it never smoked unless I relined it in neutral (once).


I think the reason the Greddy drain works is because you'll almost never find an '06 Honda motor with as much blowby as a 230,000 mile B18A1 in a 1990 Teg, for instance. My beater's D15 has enough blowby at idle to power a small windmill.

Oil drain low in the pan isnt voodoo VW has been doing it for years.

---- nig... Your turbo hangs lower tghan my sack.

Ya it makes total sense... The oils going to find its own level anyways...



Mines at the top of the pan, return ins solid line, with a bung that has a -10 to 5/8 barb... SLight downhill to it. Im not worried.


I concur with stealthnigs findings and approve this message
