I installed a new -10an female straight fitting yesterday that I purchased from summit. It was installed perfectly and was allowed to cure for 24 hours. I started the car and checked for leaks, didn't find any. Was driving to work this morning when my oil pressure gauge fell to 0. I almost panicked shut the car down and pulled into a publix parking lot to find that it had blown completely off and the engine bay is full of oil.
I am waiting for my girl to get home so I can drive to summit and get the real -10 fitting that I had ordered in the first place. I just hope the motor is ok. I left about a quart and a half in the parking lot so I know there was still oil in the car after I shut her down.

 

is this an npt fitting going into your oilpan? pics? is it one of these?

if it is this fitting, i'd avoid the push on style altogether and get a proper hose end that you need to assemble.

or is it the fitting in the oil pan?

i'd be more inclined to point the finger at the latter pic and threads it is fitting into... was it bottomed out, or were there enough threads engaged? i've never had any ss line hose ends leak. every time it has been the threads the fitting goes into being too deep or too shallow.

also, are there any kinks in your oil return line? this could also cause a pressure build up because the oil is not able to drain from the turbo properly and it eventually blows out a seal or starts coming out both ends of the turbo. i've seen this happen a few times.

If you use that part for your drain and the right type of hose it shouldn't have blown off. There is no pressure on the oil return. I have use these fittings on countless oil return setups, never an issue..

 

It wasn't on the return. It was part of the oil filter relocator setup that was flowing from the block to the filter relocator. Plenty of pressure at the oint it was at.

 

yeah, that is the wrong type of fitting for an oil line with pressure running through it... i hope it didn't come with a kit or something. you need some proper thread together hose ends. i should have realized this when you mentioned losing oil pressure.

 

when my girl gets home I am on my way to summit to get the screw tite fittings. It is what I had ordered in the first place but they dropped that one in the bag and I decided to give it a try anyway. I just want to give everyone a heads up so they don't try running 75-100 psi of hot oil through one and expect it to hold. This one lasted about 1.5 miles and I didn't rev over 4000rpms.

 

sounds familiar...





i've since upgraded to stainless steel braided lines.

 

ouch. I know braided lines with assembled hose ends are the best but is there a cheaper alternative that is reliable? What have OEM's been using for oil lines? I'm trying to build a setup for my oil cooler right now and those hose ends and fittings are just too expensive.

 

I used the push-on type of fittings on my oil relocator kit for over a year and never had a problem.
