Can the oil feed line bolt be accessed without having to remove the turbo and mani? And if i do have to remove the mani and turbo (dont want to cause of hard lines) do i need to replace the gaskets...there only 15k old. I just wanna get in there and see if its loose or what but i cant access it easily. It is getting progressively worse so i hoping its not the block cracking. I looked at it from where i can and its coming from the bottom of the bolt.
Thanks in advance
Nick

Info: Bottom mount s15 bb turbo

Yes you can get to it. You'll need to replace the copper washers on both sides.

Know that I looked at it I'm sure I can get to it if I remove a/c compressor, hot pipe, intake and oil dip stick.
Anyone have a size or part number for that washer?

OEM Copper Crush Washers

15193-03E00 (larger)
15193-P9000 (smaller)

The smaller ones are used for the oil feed line. The larger ones are used for the coolant lines.

So here is what has happened.
-The car was leaking from the oil feed line from the block. Minimal leak.
-I then loosened the banjo bolt and tightened it up again. Huge leak.
-Today i replaced the crush washers, tightened banjo to 20ft/pounds. Minimal leak again.

Am i safe to say the hard line is bad? It seems to be leaking from right above the banjo bolt where the line gets a little smaller then goes to turbo. Cant really see that good in there.

For some reason i used braided lines for everything else and used this one hard line for the oil feed. :/

wrap the threads in teflon tape. works the best

No...no...no... teflon tape is for pipe threads (tapered threads) the banjo bolt has parallel threads and seals with the crush washer...if you have changed the crush washers and its still leaking chances are the hard line is damaged.

^^ is correct. OP i'm in the same boat as you. I even tried a longer banjo bolt and it still leaks. i'm down to just blocking it off and running a new feed line. I'm waiting for the weather to break so i can get wrenching again i miss driving my s13.

Or the block is stripped...hopefully not.

^ if its stripped it can be re-tapped. but the turbo has to come out.

So yesterday I removed the whole hard line and both banjo bolts. Hard line has very microscopic hairline crack. http://i306.photobucket.com/albums/nn257/KILLERSKITTLE/3d751d23.jpg
So I ordered braided line and hopefully that will last.

Btw you can access everything by removing hot pipe, intake, and turbo outlet elbow.

I just replaced my turbo the other day, I usually put a little bit of red thread locker on the oil feed line into the turbo. Just make sure you don't put too much, you don't want it seeping into the turbo that's for sure.

wait did you remove the hardline without removing the manifold and turbo?

Yes, thankfully the oil feed line is on top...you can just nearly get a wrench in there.

Can i use the black one (restricted) to go from the block to the braided line, and use the silver one (not restricted) to go from the braided line into the turbo? I really want to get rid of the banjo fittings all together.
So the my second question is, what do i use on these fittings to seal them up? The braided line is tapered inside so do i just use thread lock to hold those tight? And then do i use pipe tape to seal the fittings onto the block and turbo?
Thanks

sorry for big pictures!
