FML: Oil cooler blew the week after I finished my build
After breaking the car in, getting it tuned to a reasonable 260hp 220lbs torque at only ~8psi, just so I could go easy on it before I put it away for the winter and then putting another hundred miles on the car with a nice canyon run, while driving my car the 60 miles from my parents house where I did the build to my house in the middle of nowhere so I could store it I hear a minor thump that felt like I hit something small.
I check all the new gauges and everything looks good, oil pressure at the sandwich plate is good, oil pressure light on the car isn't on, water temp is good, A/F is good. I figure must have hit a bit tire or something. I drive another 5-10 minutes.
Thump and an engine stumble. Oil light still not on, oil pressure at the sandwich plate is 40-80 PSI. I immediately turn the radio off and try to figure out what happened. Oil temp starts rising, so I take the car out of gear and coast off the highway and park in a parking lot, switching off the engine as turn in.
I stop and immediately check the oil level, the oil is so clean I can barely read it, but after a couple checks I can see there is still oil in there though not much. This matches the fact that I never completely lost oil pressure. To see if something is really wrong I start the engine.
Worst nightmare....knocking...bad. I immediately shut the car down and start looking around. There's oil all over the front passenger side tire, but I don't have a second cooler. There are huge amounts of it oil though, the suspension and tire are covered (yay for having a 6qt moroso pan). I look in the drivers side where the oil cooler is and there's oil spilled over there as well, though not really on the tire.
So I tow the car back to my parent's house. I haven't pulled the front clam yet but I was able to get a camera and my hand in to check out the oil lines. I had just replaced them with Sector111s one cooler lines. The video shows the lines are fine. I can't feel any oil on the lines either, they are also tight.
But the video also shows the front of the oil cooler is covered in oil. There is splatter above and to the sides of the cooler. A pool of oil has traveled along the front edge of the car over to the passenger side. I pull the valve covers and everything looks fine up top, which leaves only one likely scenario for the knocking.
From what I can tell either a weld let go on the oil cooler, which if that is the case it could be I tightened the line too tight and weakened it. Or a rock or something blew through the cooler. I won't know until I can get the front clam off. That first thump most likely was the cooler letting go. I would guess the reason I had oil pressure at the plate the whole time is I was feeding oil to the cooler and it was blowing out the front. I have no idea why the main oil light didn't come on. (Also the reason I am monitoring pressure at the sandwich plate is that my turbo's oil line t's off of the bleed valve, and I wanted to knock if I lost pressure to the turbo, since I'm on my fourth one.
So my best guess based on the noise and the lack of oil, I'm pretty sure I spun a bearing.....in my brand new engine.
