I finally blew a motor, I gotta get some jb weld and fix it. (updated)
 

I thought it was just the headgasket like my previous problems, but it looks like piston #4 melted. kinda odd that piston #4 melted before #3. I could I be looking at an injector problem here? This thread is worthless without pictures.

I heard those crazy Tullos boost controllers beat up the #4 piston on a daily basis.

:chacha: I just need to get some of that quick weld and I can patch this right up right ?

I guess the 1.5l didnt like 15lb+, tell you what I sure did like it though. That motor took 3 years of daily trashing, I'm still curious about piston #4.

3 years - not bad with 15lbs of boost.
Are you thinking of running a water/alky setup?

What caused it? Boost spiking?





















:P

That's not a bad power level for a D15. Greddy kit in the old Pigtegra, wasn't it?

I dont know what caused it to melt, thats why I'm almost leaning towards the fuel injectors... I just dont get why number 4 melted and number 3 looks perfect.

I'm not running anything great. I got the standard stuff like DSM injectors, crome fuel map thats wideband tuned. The first two years I ran uberdata, walbro pump, and DSM injectors. Its been a very solid setup. I have broken a transmission though, used up a couple clutches, the normal wear and tear stuff from track abuse and a bad case of wheel hop.

Wow, cant believe you got that much life out of it, must be a krazy motor

I double checked the date, I got that motor july of 2003. I abused it from day 1. It came with 210 compression and last check it had 205, so it was still healthy a few months ago.

I had the same thing happen on my second engine but it only took me a few days to blow up :6 I was leaning towards an injector failure as well, but I was also in the process of tuning and may have run way tooo rich.
