A consistent 20+ counts of knock at WOT since the cruise.

so where now?

Yank the head and take a closer look, try to figure out for sure what caused this. Then save up some cash and make it happy again. I guess this will be the unofficial start of round3 for the car.

Chances are I'll get a pretty vanilla, proven setup in there for years of continued fun.

Car just sounded like it was missing and generally running like crap, although anna said she couldn't really tell. It had almost a tick to it making me think it was something in the valvetrain; almost sounded like a 1g with bad lifter tick except there's no lifters in this engine, only tappets.

Heh not exactly. It knocked like a SOB on the cruise on that piss BP91 we got in superior. I feel insanely bad if anyone else is having problems as a result of this stuff. When I was logging my hybrid MBC/BCS setup is when I really noticed things getting ugly. I had about 1/4 tank of that piss 91 in it and filled all the way up with local BP93 good stuff but it just continued to knock and the logs did show something crazy like 28 counts one time. I shut it down instantly but who knows if that was the nail in the coffin or what.

Oh, a few days later (after I had noticed it starting to run worse) just AFTER part throttle boost on decel (in gear) the car would let out a short but very noticable billow of blue/black smoke. That's when I knew for sure something was amiss.

Gimme a call if you want a hand or someone to sit around and talk shit.

I call built motor set for 600+ and you end up at the 500 mark.

Good luck man.

**goodhart** · 10-24-2010

Holy crap, shitty dude! What is the plan? built motor?

EDIT: Whoops, I didn't read the whole thread.

Matt D. · 10-24-2010

I'm glad you were able to get your hands on a boroscope to confirm what we saw on the compression test. Could have done without the scored cylinder wall...

In all fairness, I put the pedal down a handful of times on that 91 octane gas and my car never knocked. Power is a nice thing, but a safe tune is even better.

95tsi · 10-24-2010

That sucks!! Best of luck getting it fixed and up and going again!!

rose0529 · 10-24-2010

Dude that sucks! I was hoping it would be something easy when you had said your compression results.... What do you have planned? Need a beer?

mdost03 · 10-24-2010

That sucks Scheides! Hope you get it back on the road soon

On a note with that Superior BP gas, I was knocking like crazy after filling up there. Had to lower my boost to spring pressure on the wastegate just to floor it and was still getting some knock. Ran it close to empty and then filled up with some local 92 octane and was boosting great again at 22 psi.

**cmspaz** · 10-24-2010

I was telling him earlier to do a 4G swap. That's pretty vanilla and proven, right?

A//// Guy · 10-24-2010

Wow that is major suck.

What was compression when you bought it this summer? Any idea what caused this? I cant imagine a shitty tune causing scored cylinder walls. Very odd.

**cmspaz** · 10-24-2010

If you look closely at the pic of the piston, you can see that it's damaged along the left hand bottom corner of the frame.

Compression was good when I bought it, ~140 across the board. Some say the rings are gapped too tightly from the factory. Maybe it was detonation. Maybe it was too much awesome.

My goal is to get the head off and verify the boroscope findings this week, then pull everything else this coming weekend (after I recover from Mark's party--friday night). So if you're bored next saturday or sunday and want to get dirty, feel free to stop by. Beer provided after you smash your first fingernail or knuckle

t-revzr · 10-24-2010

Ask Anna if I can chew in the garage this weekend?

**Murlo26** · 10-24-2010

I wanna see!

For when I blow my next motor up, lol. Next time I am doing it myself...no money for another one, lol.

But really, I will come be moral support and do what I can. I'd like to help with getting the head off to, text me. I need to figure out that stuff or at least see what its like.

GG_9_SE · 10-24-2010

Shoot me a txt on what time your gonna start man I am there.

Super Bleeder!! · 10-25-2010

Did you by chance wash down the cyl walls with too much fuel?

**scheides** · 10-25-2010

perhaps the previous owner did, I'm not sure. From the day I got it it ran anywhere from 11-12:1 afr, I logged it regularly.

**scheides** · 10-25-2010

Time to get rollin. Dinner, drinks, and pool party with the in-laws tonight so I only got about an hour in on it. Intake, UICP, cooling plate (?), coils rewired back to stock (and tested), drained coolant and got most of the wiring harness removed on the top/side of the motor/trans; just enough to get the head off.

I was considering buying a prebuilt block as Mike@AwdMotorsport claims they have them in-stock and ready to go (built by buschur) but of course that was a lie (dispite the fact that he bumped the thread THIS MORNING)--all they have is a $6000 sleeved block by darton. Overkill to say the least :P

Sigh, looks like this is getting built locally. I have faith in lots of locals and shops so this is probably best; I was just looking for a quicker fix.

**scheides** · 10-26-2010

Got a whole hour and a half in on it tonight, dinner with in-laws again, sigh. Spending all night with them again tomorrow I think but still on schedule to get the head off Thursday.

Did the knuckle-busting work tonight; fuel rail/lines, intake manifold, passenger motor mount, acc belt and all the pulleys, except for the damn crank pulley; my impact doesn't seem to be strong enough to break it loose

That's gonna put a huge damper on things!

Talking to lots of vendors to try and get a grasp on what to do for the engine (re)build. AMS could do it quick but I-beam rods are on backorder. Blocks are on national backorder from Mitsubishi. Unconfirmed, but GSC S2 cams are on backorder too. Valvesprings not ready to ship till last week in November. FML.

I took insurance off the car today, it's gonna be down for at least a month at this rate

In the back of my mind I was soooorta hoping I could have bought a shortblock outright from a national engine builder and have this thing back on the road next week, but that dream died today. Sigh.
