ive been researching spots to tap for a turbo oil return. and it seems like tapping the pan would be the easiest and noob proof method of doing so, i also read that one should tap the lower pan...

i have a couple questions, where should the lower oil pan be tapped, or should it even be tapped would it be better off tapping the upper? .

and if i were to tap the oil pan, wouldnt the tap be below the oil level and would that give me a problem and force oil up the return or some how limit oil drain from the turbo?

where on the pan should a tap be placed, and what size tap

i thought you de guys tapped the block?

Tap the block. Theres a spot in the front where the turbo motor's come tapped. use a 45/64 Drill bit and a 1/2 npt tap with a 1/2 to 5/8 npt barbed fitting.

i dont understand and i see this alot, but why is the drill bit that people recomend bigger then the tap size? 45/64 bigger then 1/2 inch, or 23/32 bigger then 1/2 inch

 

[robchaos19]

1/2 NPT is not actually 1/2"

 

[sjsdperformance]

ooo that makes sense , i found this,

1/2 " npt = od 0.840"

Try to do a search first. There's a reason why no one here taps the lower pan: the oil won't drain out of the turbo properly because it's a gravity drain.

first off i dont need to hear a lesson on searching ,
secondly theres quite a few threads where theres a debate tapping the block vs the pan, some even recommending the lower oil pan

So.. I have a question.. Would you drill a pilot hole using like a 1/4" or just use the 45/64"?

I've always said the same thing, so imagine my surprise when I was changing the oil on my 06 2.0t GTi, and saw that the return is to the bottom of the pan.

I still wouldn't do it on an SR20, since the lower pan is so shallow, and the return would be hanging low.

The size of the pilot hole isn't critical.

I would drill a pilot hole. It doesn't matter if the hole is a little off center on the blank spot on the block, but it just makes it a little easier to stay on target.

 

[chriscar]

Oops, I read his question incorrectly. I'd absolutely drill a pilot hole first, no doubt about it.

yeah definetly tap the block, its not to say that tapping it into the lower pan wont work properly, i mean the evo's use the drain directly back into the bottom of the pan so i mean its all going to drain, gravity works the same way, but on the sr the pan does hang down really low so i wouldnt do it there, its much more simple and cleaner to just tap the block. I mean this is the way the det's came from factory why not go with it.

wow, attitude. he was just tryin to help you out with the question you asked. It did sound a bit newbish. Anyway I will vote for tapping the block, doing it that way also helps for a much cleaner install

 

[SentraDude]

Ok... where do you get a 45/64 bit? Went to: Harbor Freight, Sears, BAP, Napa, Ace, Home Depot and nothing...

 

[swiss]

Call around, you may have to special order one.

Only i dont think this will fit a standard drill... 1/2 chuck, is this a regular drill?

 

[LikeTheMovies]

yeah you need a 1/2 chuck. you can also use a 23/32 bit either one will work.
