Give me some ideas on how to fix this problem

[moses]

Sorry for making so many threads but I just cant figure this problem out. I stripped out the threads in the block that the coolant line go to from the turbo and I dont know what to do. The guys at enjuku racing said I cant heli coil it because the banjo bolt is a pipe thread and no one makes heli coil like that. What other choices do I have?
Can I use a bigger bolt and maybe dremmel out the hole bigger on the cs turbo line I have? Or where would I find the a new piece to put on the end of the turbo line with new bolt? Do I have to have pipe threading?

does anyone know where to get a 14mm Banjo Bolt Adapter to -4AN Male or 12mm to 14mm Conversion Banjo Bolt?

Have a machine shop look at it..... it would be easiest to ask, but that is pretty tough cause your motor is there. Take the end that goes into the block to a hot rod or marine shop or a machine shop and just ask.... They have a better idea of stuff...

Whoa whoa whoa.... whoa.

Slow down there, speedy.

If I read correctly, what I think you can do is just drill the hole bigger, and get the next size up pipe tap. What you gotta find out is if the threads are NPT or BPST. Then, you can get what's called a union, or 'bushing' fitting to thread into the larger pipe tap threaded hole, and thread your smaller fitting into that union.

Follow me?

Since I have cs lines and -4 lines that unscrew, could I just get these from ebay and tap a bigger hole after I figure out what thread it is? Also is it ok that the previous banjo bolt was 1.25 and the new one will be 1.5 since I am going 2mm bigger?

Hey guys I just drilled a bigger hole, tapped and put a m14 bolt where the m12 banjo bolt used to go and it went bad:dead:
I tightened everything up and started the can and for some reason the banjo fitting is still leaking and bad, but that is not even the worse part. There is also a lot of oil on the ground with the coolant. Did I drill too deep and hit a oil passage or something? I didnt see anything when I first drilled it and I just went as deep I needed to.
I also took off my ac and bracket. Could it be coming out of those holes as well. I have no clue what the hell happen. please help. I got a week before I get shipped off.

[Mr. Miyagi Voice] Ayahhh... why you so stupid? [/Miyagi]

Just messin with ya. Okay, so what motor do you have? Post pics of the banjo bolt and the hole you drilled. Its quite possible you hit the oil gallery.

It is a sr20det. I have not got a chance to get back to the car yet, but I was just wondering if I should have put that teflon tape on the banjo bolt for the water line. I always hear about never putting on teflon tape on turbo lines, but I can not stop this from leaking. The bolt is in there snug too.
If I did mess up a oil passage can I fix it somehow or should I just buy a new engine?

[japslapsilvia]

something is not adding up. the turbo water feed ports on the block are M-14 1.5 they are NOT a pipe thread, and yes you couuld have just helicoiled it b/c the banjo bolt seals with a crush washer.

the M12 bolt is for the oil feed not the water line.

and the CS lines use -3An for oil and -6AN for water.

[LA_phantom_240]

Dude I honestly have no idea how to help you at this point, cause I can't picture what it is that's going wrong. Pictures speak a thousand words.

Yeah or cars must be different or something. The line off the turbo that goes to the bottom of the hole on the block is a water line. I have cs lines and it is a -3an and I just put a banjo bolt in that I had to drill and tap that was M14X1.5. This I am sure of.

I just had my girl start the motor while I under the car and I dont know how but oil and coolant poures out of the fitting fast (like a quart in 2 seconds). I had a video, but I accidently deleted it. So I think I am going to have to trash the motor and buy another one after I get back from Iraq and let someone else do the work. This sucks. Any suggetions on what else I could do would be helpful. Here is a pic http://i277.photobucket.com/albums/kk46/aks240/damnleak.jpg

the bottom most fitting, the one leaking in the pic is the OIL feed line, the one above it is WATER. did u use crush washers?

[los_inc]

get an aluminum -3 AN fitting and have some one welded it in

Ok I am so sooo confused right now. Before I took this off it was 100% coolant. I think. I am second guessing everything right now. OMG I just remeber thinking it was oil a while back, but then again I remember coolant spraying out of it, I am so confused its not even funny. Damn and I did add some dye a while back to change the color of the oil to find the leak.
OK here is the plan. I am going to unbolt that bolt right now and see what comes out. If it is just oil, then im good, if not then ill just be confused.
Why is damn fitting still leaking. It is tight enough and yes there are crush washers on each side? My head hurts.
Another question. I did not drain the oil when I took out that bolt and I had my oil filled up, Why the hell didnt it leak then?

[moses]

Ok first I just want to start off by saying I am stupid.
Second I took the bolt out and nothing. Never even dripped. So I went for the oil pan.
As I unbolted the oil pan bolt there was only a little dribbling, which is bad because that means there was a lot of oil but good because my radiator is still full.
1.This is what came out. I am not sure if there is coolant in there or not because of that dye. How can I find out for sure?

2.This is a pic of the bolt I pulled out on the right and the one I put in on the left. Is it ok that the one I pulled out has a bigger hole comming in?

3.These are the crush washers on the bolt. Do you guys think the washers are too loose? How do I keep it from leaking?

doesnt sound like this is something that an online forum can help u with. u need to have someone look at it to help u out.

[japslapsilvia]

well i dunno what to tell u about the color of the oil considering you put dye in it....

but the banjo bolt u are using is/was the coolant bolt correct? that will lead to over oiling of the turbo, no restrictor. not that, that is a concern now since its leaks. the washers u are using look fine, how well does that bolt fit in the actual banjo fitting? is it supper tight or loose? in all honesty the best solution is prob have a fitting welded to the block.

edit..if there is coolant in the oil you should notice "bubbles" b/c the coolant/water wont mix with the oil. the oil will sit on top of the water/coolant

[moses]

What I did was tap the hole more because I think the bolt may have ran out of room. So I will try it again. Do you guys see any problems with me using the washer with ruber in the middle? There is rubber in the middle of it and it fits tight.

[LA_phantom_240]

Does that area get hot? If so, go with the copper. Copper crush washers are extremely common. Look at your brake system, for example.

[moses]

Well I seemed to have fixed the problem. I did use the washers with the rubber so I will see how well those hold. I just ran it to redline and there is zero leak. I am pretty sure I just diddnt tap it far enough and the bolt ran out of thread as I got to the end. Hopefully it doesnt burn up or anything. I dont think there was coolant in my oil either. The guys at autozone said they thought there was gas in my oil, but I have a wideband and I think I would see it one cylinder was getting spark. Anyways thanks for all your help and comments. Hopefully I can dyno before I leave.
