I think I blew my engine.
I just finished my new build. Nothing fancy, just a stock d15b with turbo on 7psi.
I went to take it for a ride and test it out after I re-tightened the chargepipes and re-set the wastegate. After a few pulls, I realize the thing would stall every now and then, and I though maybe it's just the battery since that thing is a few years old. The idle also became lopey, kind of like the old muscle cars with carbs. I figured my plug wires were off, or maybe the FI's were acting up since they hadn't been used in 10 years. No big deal, the car was still driving, but misfiring a little at idle. It would have a hard time starting back up, which I though was the battery, and I decided to go to autozone to have them test it and the alternator.
On the way there, I run into a guy with a new roush GT, and I started talking to the guy, told him I just got done my build, and wanted to see how well it pulled, and asked if he was up for a little challenge. He was quite confident his 475 factory HP would smoke me. Once we got away from traffic and out to a side rode, the lights turned and we lit it up... actually I lit him up, and smoked his ***, which was pretty awesome.
We parted ways, and I went to autozone, dude checked my battery, and said he thought my cam timing was off since it still had a hard time starting. A storm was coming ad I had to wait til I got home to adjust it anyways since it has a stock cam gear.
On the ride home, I'm pulling up to speed on the highway and I start having trouble, and the engine starts to sound like it's running on 3 cylinders, but no check engine light is coming on. I'd checked the spark and FI wires and everything was good, so I didn't know why it sounded like crap. Only thing different then before was the seafoam I'd put in at advance to help clean the injectors if they were gunky at all.
Anyhow, I'm almost home, and there's traffic so I was worried to get stuck in it and have the car stall and not be able to start back up, so I have to go another exit and take the longer way. Half a mile down the road, I start seeing a giant cloud of blue smoke behind me, and I thin to myself, "****, I must've blown the head gasket", and have no choice but to continue to drive. The turbo's still spooling so it's not the turbo. Coolant temperature is normal level, and no CEL goes on.
I finally get to my driveway, pop the hood to see what's up, and there's oil spewed everywhere on the passenger side. My feed line is not broken, my drain line is fine, and plus this stuff is basically covering the whole transmission, the firewall, and my driveway. I look closer and realized it must have been spewing from where the breather tube used to be, and where a tiny filter is now without any catch can since I'm on boost...
So I'm trying to figure out how this happened and what caused it:
1) I did replace the PCV (correctly) back when I did the swap, so I don't think that could be the primary cause.
2) Blew a hole through a piston
3) Burned a piston so bad that so much blowby is causing oil to spew as a result of high crank case pressure
The only other thing I can think is that I was running open header, which boiled the oil in the pan, and it spewed out from the high pressure of boiling, but like I said, the engine coolant temp never went above normal, if that is any true indicator of true engine temperature...
What do you guys think?
Thanks,

Re: I think I blew my engine.
lol can't tell if joke or not...
at least one piston melted or with broken ringlands...
Also, who in the hell calls a plug wire an "FI"??

Re: I think I blew my engine.
Maybe he's talking about his injector wires? Also, yeah, the Roush wasn't racing. He was letting a kid (you) have some fun.
If you're blowing that much oil, it's gonna be obvious where it's coming from. You don't just suddenly get explosive oil leakage without making a hole. Find the hole.

Re: I think I blew my engine.
When i broke a ringland it still drove fine but i could tell it was just slightly off.
It wasnt untill i got into a little boost i noticed a lot of smoke coming from my catch can. Did a compression test and the cylinder stilll made 140 psi. All the others were at 270 so it was obvious the ring lands broke.
So the motor can run like **** or it can just barely run like ****.
In other words yes youre right english is retarded

Re: I think I blew my engine.
I mean, there's cracking/breaking a ringland, and then there's "pardon me while I break a piece off and **** your mother with it" breaking a ringland.
Engine sounding like it's running on three cylinders + massive puddles of oil everywhere = click here

Re: I think I blew my engine.
Do a compression test for sure if they come out bad pull the head off. Was the oil watered down and your radiator needing water? That can be a cracked sleeve as it all pushes back out through the BOV or any opening it can, hope you were tuned. If its only oil they're probably correct. Could You post up some pics so other people who might be reading can learn what happens.

Re: I think I blew my engine.
it sounds like an injector is stuck open to me i had this problem when my injector number 2 failed and stayed wide open. a huge cloud of whitish blue smoke and having a hard timing starting it up due to there being no fuel pressure in the rail
you issue could be ittermitant injector failure so sometimes it works fine some times its stuck wide open

I ran comp tests on all cylinders which came out to about 160 except for #1 which was at zero.
The **** wouldn't drive past 35 and was barely passing 3500 Rpm
Coolant looked ok.
I refilled with oil, disconnected the #1 fuel injector, and drove it a 1/4 mile without smoking.
Anyone got any pistons, rings, rods, and rod bearings for a turbo setup for sale? I don't care what they are as long as they work properly and aren't near failure.

Re: I think I blew my engine.
It's a d15b.
I've read the strokes are the same, but only well to tell if dimensions were congruent would be if the dimension from centerpoint of wrist pin to rod journal is the same on both...and milling either would weaken the rod structure...might just stick to d-series,bro.
