Well It's been a long time time coming but here are pics of my pistons (all 4) and the damage that incurred for being boosted for 2 weeks, I first noticed white smoke pouring from my crankcase breather, so I immediately quit driving the car. I hoped for the best case scenario, but braced for the worst. Which is exactly what it happened to be. I had a compression and leakdown test performed, none of the pistons were sealing and more than half of my valves were leaking. Compression was 230, 212, 190, and like 160 or something close to those numbers, (Motor gave way about 6 months ago, took this long to save up for the rebuild) The link below are the pics I received today from my engine builder. The block pics are hard to see, but he was showing me the cylinder wall damage, bad scoring/scraping and a few little spots where it was starting to melt. and the piston pics are pretty self explanatory.. I will update with the rebuilt pics as soon as I get them! both block and head!

So what happened?

 

Well the tuner and engine builder both agree, that the engine must not have been in the best shape prior to turboing, and thats my fault for not checking beforehand. Coupled with what seems to be a very bad tank of gas. so detonation from that lead to pre-ignition= melting and so on..

 

oh dude I'm sorry to hear

 

Now me and the mad scientist gotta rip apart the block, and replace the pistonri gs your fried!

 

Maybe post up a bit about the build, miles one the car. I can't tell but is that piston melted a bit, if so your tune caused this.

 

Something tells me this wasn't due to being an "unhealthy" engine

 

yea what backdoor tuner was this? detonation would look slightly different to the caps of the pistons.

 

What's the tuners name, what shop told you that?

See this is the main reason why I took the 2k worth of EFI tuning training course's to see what tuners really get paid for and know the facts instead of some bs.

Which this looks like. BS

 

not a "backdoor" tuner
