Need Help - oil supply tap MIA
 

Installing the basic GReddy 1.6 turbo kit.
The oil supply tap is MIA. (Tap that is inserted into the engine crate and further to the braided supply line). I need to find a replacement. Could someone please let me know which tap is a direct replacement for the one that comes with the kit? Or tap thread measurements and a possible location where to buy.
I did a search and found a link to an plumbings site. But i am not sure which tap to order.
PLEASE HELP!!!

Are you trying to tap the block itself?
Thats not the right thing to do. You need to make a new oil feed line that can run from the oil pressure sender on the other side of the engine.

Or are you looking for the fitting that threads into the block?

Fitting that threads into the block and then attaches to the oil supply line.
Has two threads on both sides one for the block and one for the braided line.
Thanks

you want a M10 x 1.5 to -3AN fitting, good luck....search here, there's a few sources we have found

going with the -3AN fitting will necessitate a new oil feed line as well.

Ok I found the thread discussing this:

I am hoping to retain the line. would 10Mx1.5 -3AN let me do that? or do i need to order -4AN?

Thanks,
Alex

-3AN will match your existing line.

Many thanks. I will let you know if this worked for me once I get the part.

make sure you have a copper washer for the block.

Got the oil fitting today. Fit like a glove. Thanks to everyone for their input.

More problems elsewhere thou...

1. Oil leaking from the banjo fitting on turbo. I've put two copper washers as per instructions. One between the turbo and the fitting. One between the bolt and banjo fitting. At first I was getting oil from the bolt to banjo connection. Tightened that. Now getting oil from the banjo to turbo... I am afraid to overtighten. I am thinking of buying new washers... What kind to get and where?

2. Seems that my exhaust manifold gasket isn't doing it's job anymore. Car sounds awsome, but the sound is coming from all the wrong places. Looks like an exhaust leak from the block to manifold between 2nd and 3rd headers. Could this be caused by "releif cuts"? I made 3 as per recommendations on this and other sites. Has anyone experiences that?? Most likely it is the gasket, but I wanted to see if anyone had seen this happen before. All the bolts were tighted as much as humanly possible. Some are extremly tought to get to even using professional tools...

You may find the copper washers at an auto parts store.

Are you sure that you didn't pinch the bracket for the water return line from the heater core between the manifold and block. Some of us have.:gay:

Yeah I saw references to pinching the bracket. Something I will need to check. The exhaust leak feels like it's coming from the top, unless it's bouncing off the block. :confused:

Sometimes you can 'refresh' CU washers by heating them up w/ a propane torch till they're red hot. But I guess I'm pretty cheap...

Is it possible that Mazda's replacement Exhaust Manifold gasket cost cheaper than NAPA's? Always thought dealer prices were higher.
Napa is $21.49
Dealer is $10.50

Take a piece of vacuum hose and use it like a stethascope. Put one end in your ear and use the other to pin point the leak, it'll be really obvious when you find the leak. It'll sound like put put put at idle.

I'll put my money on the turbo to manifold flange.

I was actulally sticking my ear in there... feels kinda hot :) I am sure your way is safer and more accurate, but it definetly sounds like the manifold to block. My bet is on the water line bracket. I wont be able to try it all out till Saturday. Just getting all the parts that maybe needed for the weekend. Replacement bolts and gaskets...
Question is - is Mazda Gasket good nuff for 10.50?

yeah why not it is doing the same job and sees no more than stock stress at anypoint.

When I had a pretty significant exhaust leak at the manifold/turbo flange I could swear it was coming from the manifo/block flange. But when I did the trick with the vacuum line it showed me exactly where it was. Just don't want you to tear it all apart only to find out the leak was in a different location.

As an FYI, what did you do to ractify the turbo to mani leak? new gasket? or removed the gasket all together?

Btw. Mine doesn't sound like a small leak. It sounds like I don't have any muffler. Very nice and laud. If it were coming from the back of the car, I would keep it :-)
