When you guys do the installs on these kits, the hoses MUST have some slack in them. The engine is not solid mounted to the chassis so as the engine moves under down shifts, and up shifts, it will pull on the hoses if they are too tight and rigidly mounted to the sub frame. That is probably one of the few ways i could see there being enough force to yank a hose end off of a JIC hose assembly like that. Assuming it was properly assembled of course.

that's a good point sam... op, any thoughts? was there enough slack?

Lou's Defi gauges are f'ing nice, but I'm sure they cost a pretty penny.

I wouldn't mind replacing the clock with an oil pressure gauge... even if it's just some Autometer.

I think the gauges are around $2-300 each but top of the line, need the control unit as well. To the OP if you are selling your oil cooler let me know. I agree with the members who have said that the aftermarket for the Z is going strong. These things happen hopefully GTM can chime in their take since it's there kit. Did you leave any slack on the lines because I could see how that could cause this.

Yup. Even the Defi analog gauges are ~$250.

On my journal I will have a part out as soon as I can get rough idea of what I can sell and how I am going to ship the parts since my truck is 2 hours away from me right now. I will post it in the for sale section since its where it belongs but until i will update it on the progession thread. Still need to make sure the oil didnt damage the o2 sensors on the instake. Its all over the sensors especially the passenger side. And yes, believe me when I say we tried everything to basically make the oil cooler fail before I filled the block and started the car. It had enough slack but not too much to where it may snag on something from an abrupt shift in weight or shock to the car. It was just faulty I will take more pics of the actual AN fitted and closer pics of the hose. I think the oil should have purged out of the core by now.

Man I feel for you I do, I just got an oil change done with ester and we all know that sht doesn't come cheap, good luck and hope it all turns out OK.

Everybody should have DeFi gauges!!

Like the topic states. Right above the AN fitting it sort of mushroomed on the end that connects to the thermo plate. I dont know exactly what happened as I didnt feel like looking at tonight. Not as mad as I thought Id be but disappointed. Any ideas? I mean everything was sturdy, tightly closed. the core didnt even budge from the bracket we made to attach it. I am really disappointed and I hope nothing internally was damaged since it pretty much drained the entire system of 6.4 qts or so. Basically what happened was right after the install I drove the car until it reached 180F. The I redlined the hell out of it for a while. The temp was still doing good and there were no leaks of any kind. Then I decided to take long route home on the freeway and see how it did on the temp while highway driving. All I remember is at one point I down shifted from 6th to 4th at 80mph and brought it up to about 6800rpms and thats when it happened. Any ideas? were the hoses not sealed properly above the AN fitting.

Here is the pic of right after we installed it. Of course its not the aftermath pic. I really wasnt in the mood to even lookat the car I was so disappointed.

First of all we do apologize for any inconvenience we may have caused. a replacement hose has been sent out last week with a return shipping label so we can get the old part back to further investigate what caused this issue.

Couple of points that i would like to make, This is the first time that we had this happen and we have sold lot of thees kits, Now defiantly a mistake could have been made in the proses of assembling the hose, but also base on the picture you posted above there is really no slack to the oil cooler hoses what so ever and with the engine torquing against them could cause the problem you're having .

Sam

^ not to disagree or agree, but even if there was slack you wouldnt be able to see it in that picture. I'm not really interested in blaming anyone, these things happen even to the best dealers every now and then.
