owner is kilmer on here… pulled it last night… going to crack the valve cover to see exactly what happened… nice hole in the back and front of the block… oil filter housing was thrashed… not a bad job at all!

Cute.

yeah…so looks like I’ll be needing anew motor… :rolleyes:

ths to sailor/sonny/and brian for the tow!!!

Whoops. I’d guess the rod broke looking at the holes. http://www.dub-tech.com/forums/images/smilies/drivingskid.gif

we’ll pull the head tonight and see what had happened.

WOW that sucks…

Wow, thrashed it up pretty nice… I’m completely unfamiliar with volkswagons, is that a stock turbo that has had some work done to get it to 20psi, or aftermarket, etc? Any work done to the bottom end or anything before it blew?

reading > you :smiley:

too much NAAAWWWZ did he blow the welds on the manifold or what?

Curious what software you were running. APR? GIAC? etc…

my stock turdbo pushes 20 all day… not an issue… they are tiny turbos… although, he was pushing a t3t4 50trim? dont remember… but you figure he was a solid 300+whp and was pushing it.

bottom end was stock… there are motors running 400+ on stock bottoms, but then again, he drives the hell outta his…

still don’t know what happened… we’ll figure that out soon enough.

eric:

he was running the revo big turbo software for a tseries… what i was thinking is that he was putting load on the car uphill when it popped… so my guess was the fact that the revo software is written for 440’s but also maxxes them… so you figure going uphill high boost on a maxxed injector can’t be the best situation… still dunno though.

my theory is oil issue… as dont see rods go w/ fuel issues–pistons go w/ fuel, rods w/ oil.

so uphill, blocked pickup tube, motor under laod, rod= bye bye.

will see when tore down.

dam val!

do you have a t3t4 badge on your car

^ yeah he does

UPDATE:

ripped the motor apart last night…

so the pickup tube was clear… some metal shavings, but still free flowing… i dunno… plugs look mighty lean. what you guys think?

wahts weird is that it doesn’t look like any of the valves touched any of the pistons? maybe they did and didn’t imprint in them? i don’t know… going to play with teh head and crank tonight.

:doh:

wow.

u wont get notches w/ 1.8t pistons.

why not?

whats the best way to tell if the valves are shot? actually pull them

How about injector stutter? One of those infamous 1.8t VW “intermittent fault to ground” for killing the injector for a split second under boost…suddenly, that piston is super lean and POP…
