K20A Turbo Pro’s and con’s question

[Lukezen27]

Well people

Yall new it wouldn't be long before I started asking questions about boosting my EP3 hahah

My question relates to the oil return line..

Now on a K20A the sump hole and bolt are directly below manifold making it a great option for the return line instead of going to the huge trouble of removing the pan and welding on a new one...

Pro’s and con’s of doing this?

In fact the GRRedy kit uses this method but not many others do, why not?

Huge trouble removing the pan? Is it harder than a B series? Cause B series is easy as.

Quite simple rule. As long as the drain point on the turbo is higher than the level of oil in the sump pan it will drain fine, even if the point of entry to the sump is below oil level, in this case the sump plug.

Hey Deano

I could remove my B with my eye's closed

With the EP3 you need to drop the whole sub-frame

And yeah is seems quite simple and should work fine but all the build posts on EP3 they're removed and welded and new one

remove it and weld on higher than the oil line, lower could cause a backup of pressure and oil and kill the turbo espically a ball bearing on very quickly

All I can say is 'Ya must have a good paying job!'.

Seems to work fine for the GRRedy kit Ryan

Nope just a folklift driver but i'm good at saving

i wouldnt use the greddy method....
it will be worth while stripping the k-sump out and getting it welded, and in the mean time, get a baffle too...

When the oil comes out of the turbo through the drain it is all "frothed" up, like the top of a milk shake kind of. This is why the drain tube must be much larger than the oil feed. When oil is in this state it is much less dense than the oil in the pan and if it is returned below the surface level it will have trouble leaving the drain pipe, it will just build up on top of the oil in the pipe. If it is above the oil level it will easily flow out.

Not the best explanation but that's how i think it works. I can draw a picture in paint maybe if I haven't explained it clearly.

I completely understand how gravity works

The oil in the return line will stay at he same level as the oil pan level but should keep flowing without a problem using -10 with a huge hose

I'm seriously thinks of using this method as no one has shown me any real reason not to

Though the frothed example is the closest so far

That's the trick!

But my question is why not use the method?

the common sense things, says how can u return oil or any liquid into something (oil pan) that already has oil in it....
especially when trying to return it into the bulk of it, regardless wat greddy or anyone else uses, the oil return needs to be as high as possible in the sump/pan and above the oil level in the pan ...
