AN fitting movement / rotation on Oil Cooler Lines?
 

Are the AN fittings supposed to be able to rotate freely? What about the steel braided hose connection to the AN fitting itself?

Also, I can completely rotate the hose while holding the AN fitting portion with a wrench. Is that normal as well?

DAMN IT!! The GTM line just burst exactly like Tardcore's did. I KNEW I shouldn't have bought that kit from him!! It is definitely the lines that GTM supplies, as I really thought it was odd that the hose itself would rotate freely from the AN fitting itself. I doubt that GTM will do anything though, as I bought the used kit from Tardcore.

Prior to it bursting, I took these pics just minutes before I started the engine.
You can barely see the seepage, but it builds up where the hose and AN fitting meet.

This is what it looks like when it burst, once I started the engine:

You can actually see the oil dripping still:

When Tardcore's called us saying that the hose we supplied with the oil cooler kit has burst, we assumed responsibly and send a new hose with a return shipping label for the old hose. Upon inspecting the hose we got back, we discovered that the hose has been shorten, we order thees lines pre-cut to an exact length . if you shorten the line and you don't have any experience in reassembling this type of parts, the line will come apart . and this exactly what happened in Tardcore's case . so what burst right now is line that was taking part and shorten by the original purchaser. and this is the only reason why you would have a line that is a lot longer then the other one, per you pm.

Damn Tip. Can S&R help you on this one? Hope things work out for you. Show us those rims too.:pics:

Those reusable fittings are a pain to assemble correctly.

Shouldn't the oil lines run underneath the sway bar? Whenever the car moves down (and the sway bar moves up) the bar pushes against the lines, resulting in the line pulling on the fitting?

naw they just take some practice. They are pretty much indestructible when properly assembled though.

so what GTM is saying is tardcore screwed with his lines? can we get his opinion on that because i swear to god if my lines blow on my GTM sometime after i install it there will be a very pissed of man knocking on sam's front door. if tardcore screwed with the lines then i'll feel better, and care less that he hates his car and thinks he should have gotten a vette, then i currently do (which isn't a whole lot).

That explains it perfectly! I had wondered why the 2 lines lines (the new one in package) and the used one he supplied was almost the same length. I did not change the length of the lines at all. I used them exactly as Tardcore had supplied them. I will get another shot of the excess length of one of the lines, as they are installed on the car. That probably won't happen until this weekend, however, as I was so distraught that I did not want to work on it last night. I still need to get the car back up in the air, finish cleaning the oil, take off the front bumper and THEN I will take some pics.

Either way, how much will it cost for a new set of lines?

The angle at which the lines are supplied you can not run them underneath the sway bar. Trust me, I have plenty of length for it to adjust with the movement of the car. In fact, these lines blew upon turning the car on .. and not while driving the vehicle. Thus, no stress was tension placed on the lines at all. That further proves GTM's point that it appears the length of the lines were altered. I just assumed that what Tardcore gave me was in working order and without alteration from what GTM supplied.

I sent him a PM a few days back asking if he did anything to the lines, but he has not responded. From what I can tell, he has not visited our boards since the end of February.

I am going to order a new set of lines from GTM and I expect that everything should be in working order upon the 2nd time around. I kept thinking to myself that it was odd that the lines themselves could rotate freely from the AN fitting. I drove it for one day after the initial installation, and check the lines and that was when I noticed the seepage. I double checked to make sure everything was snug. I even posted on the forums asking if there should be a specific torque needed on the AN fittings. I was beginning to think that the seepage was normal, until I turned the car on and actually heard the "pwhoosh" sound of something popping and the gurgling noise of the oil spraying everywhere. I guess I can be thankful that this happened in my garage and not out on the road somewhere (my wife may think otherwise due to all of the oil on the garage floor .. but oh well).

Apparently that's the case. Whomever assembled or reassembled the AN fittings did not have a CLUE as to what they were doing.

Shame you had to be victim #2. Stainless lines just do not come apart unless done incorrectly.

well you should only need one line if you have the one new one they sent

He actually doesn't need any if he reassembles the one bad end..(these are reusable fittings)
Scroll down to page 5 in this .PDF for instructions. I'll be building a few lines this week..

Good point. The thing is that line is sooo long. I guess I can switch it to the other side to help take up some of the extra slack, and perhaps just need the short line from GTM. It just still bothers me that the line just came off like that .. it makes me wonder whether he attempted to alter the "new" line as well. I should have taken more pictures of the items received as well as the installation. At one point, early in the process, I did think it was odd that the nut portion of the AN fittings appeared to worn a bit .. but I passed it off as normal wear from installation and removal.

Mod, I do not feel comfortable cutting the hoses and doing that myself. That was the whole reason that during my transaction with Tardcore, I kept re-iterating .. ok so I get the good "used" hose (under the assumption it was untampered), the new hose, the setrab core, and mounting bracket.... Little did I know, he had tampered with the other "used" hose as well.

A/N fittigns assembled properly will work. It is somethign that should be checked frequently though like anything else. Assembling them is not hard just take your time and do it right, make sure the lines are properly seated in the fitting.

I guess I "could" do it if I had to. But, I just assumed that the lines provided by GTM are of the proper length already. Right?

I initially never knew the 2 lines supplied were supposed to be different lengths. As the ones I received were within one inch of each other in length.

I just took this from the GTM website:

(1) 55" S.S. Braided hose with 45 degree swivel ends (-8AN)
(1) 48" S.S. Braided hose with 45 degree swivel ends (-8AN)

Understood that you would like to have had them from factory perfect fitment etc... If you are upto it and mechanically knowledgable, it is an easy task. Cutting lines is not that hard either, there are many websites that have how-to-do articles relating to this as well. But hey, this gives you a chance to upgrade to larger lines potentially ;)

TipsZ,

Racer Parts Wholesale offers a product called Koul Tools that makes installing reusable fittings on braided hose much easier.

LOL...Jack, I just ordered some stainless line and a few fittings from you. Read about that tool...If I were building these hoses on a regular basis, I'd have it in my shop!

The installed GTM kit has 135 degree fittings on 1 end and 90 degree fittings on the other.

Yeah, they updated that. Looks like the set in question was the newer angle spec.

I am sorry to everyone in this discussion as I was not active on the site for a little while. There really is no way for me to prove that I made any adjustments to the lines. With that said, both hoses I received had 90 degree and 45 degree angles. I requested these AN fitting from GTM on the purchase order because their site stated 45 degrees on both ends which as another member who has their first kit stated it was hard to install with only 45 degree ends. I have spoken with TipsZ and Sam over the phone on the matter. I posted on the other thread with my oil cooler issue that I had 2 completely different length hoses than what their site describes. A 59" and 55". As was stated in the other thread the 55" hose I sent back was measured shorter than what they normally send in the kit however if I received two completely different hose lengths from the get go, than what are the normal lengths? There is no way for me to prove this true or incorrect. I hope that TipsZ's Z was not harmed at all and as I said before, there is no way for me to prove anything. The only thing I can do is apologize to TipsZ, which I have done over the phone with him, and Sam along with GTM.

hmm well i bought the gtm kit a while ago and it comes with 2 45's and 2 90's with no special order conditions. i believe it has been that way for almost half a year after someone did an install of it upside down and it hit the plastic under cover.

I think that when GTM first started selling these they came with 45 deg ends right. I think that those that bought the first few sets and installed them contacted GTM and I think that that is when they started 45 and 90 deg ends even the website was not updated.

I hope that the blowing hoses stop at GTM hoses and the socketless fittings..
Hopefully with the hoses I get from Mike will be end all for me and keeping track of these threads. Sorry to all those who have to go thru this oil mess and engine tragedy.....

I am planning on picking them up today.
