Project 930 The Resurrection

[TurboKraft]

#1 piston


#1 head


A prior technician clearly knew there was an oil consumption problem on #6 -- he installed an "anti-fouler". Worse than shade-tree. This is just hack.


6 - 5 - 4 side


#6 has broken ring bits in the cylinder, on top of the piston


#4 piston


#4 head


Multi-piece rings. Top ring broken about every 4mm.


Melted piston dripped onto the rod

Wow...I do not even own this car and those pictures made me *VERY* angry, the carnage, the damage, the poor workmanship goes on and on. I have an idea how much Lincoln spent with past shops, and from the autopsy or diagnosis I would be seeking some form of retribution...atrocious.

However ever comforting to know that TurboKraft will werk their magic!

I am speechless.
I am eager to hear the explanations about how this carnage happened.
Thanks for sharing that with us.

Surely stones could fly up and hit the filter, too?

[tj930]

Jeeze, Lincoln - I just looked at the other pictures.

Wish you all the best - you're in safe hands.

[krasuskyp]

Oh Linc! My heart goes out to you brutha!

I knew you'd had issues and seemed to be continuing to have issues but had noooo idea how bad 'BAD' was. Heck I didn't even frickin KNOW folks could build something *that bad* at these levels of play... I'm speechless, and cannot begin to fathom how gutted you must be.

The carnage is just endless and goes on and on and on... OUCH.

Not that anyone deserves 'that', but worst part is Linc's the damn nicest dude you'll ever meet. Really really really sucks that there's folks in the world that would do that, and esp to someone as cool as you my friend.

I guess solstice is found in that you've hit rock bottom and the only way is up - and UP in GOOD HANDS. With Tom's project birthed to near infinite awesomeness just ahead of you, you've got solid inspiration for your soon to be found _destiny_.

To end on a positive note, let's look @ happier times (amazing times) with you and your car before all this reared its FUGLY HEAD:






Linc... note I spared you from what you knooooow is my *fave* pic of you... fear not tho, I'll deploy that somewhere throughout this tread @ a fitting time 8-) (!!!).

YouTube - pkrasusky's Channel (crappy vid, you were too fast for mere mortals to capture on camera apparently)

When you're done Linc, you're going to have quite the fantabulous creation - I always enjoyed the direction you went w/ it overall... factory looking but better. Also really dig that about Tom's uber930, haven't chimed in on that yet but well played sir, and to all involved for that matter.

Take good care of Linc, Chris... tho that's sorta a foregone conclusion...

WHOA.............................................. .................

Serious Trauma Center......................

But you got the best DOC IN TOWN..

[jwasbury]

Holy $hit! Shaking my head in disbelief and disgust right now.

Chris, can you explain what we are seeing for damage on the piston crowns and the cylinder heads.

I have these thoughts that immediately come to mind:

1) the deck height was not set correctly.
2) detonation blew away chunks of piston crown that remained in the combustion chamber and "bounced around" causing the carnage.
3) all of the above

Shameful that so called professionals can take your money and let something like that out of their shop.

[MikeD930]

Oh smokes! Talk about half a$$ed, hack jobs! What a total rip off especially the fuel lines among others. It's too bad that this will require total engine rebuild. But it's in GOOD hands! Can't wait to follow your progress.

Linc, as others said...I feel for ya...being shorted and taken advantage of which should happen no more (excuse my poor grammar!).

[jwasbury]

Excuse me...WTF is an "anti-fouler"?

And this is installed in lieu of a second sparkplug on #6 cylinder? It also appears to simply vent to atmosphere?!?

ARE YOU F_ING KIDDING ME!

This thread really pisses me off.

[jwasbury]

Ok. Now I am quoting myself...

Looking at this further, I suppose the spark plug threads into this gizmo and its supposed to "insulate" the electrode from oil and crap in the combustion chamber by moving it away from the action...but in the process reducing the spark plugs effectiveness in lighting off the mixture.

Unreal. At least now we all know how we can make our plugs last longer.


Linc, thank you for being forthcoming with your current engine. Many others would bury their heads in the sand and try to prevent this type of thing from becoming public. I think we have as much to learn from the bad jobs as the good ones. Just keep in mind that none of this stuff is directly your fault and when it gets done you will have the 930 you deserve.

[jpnovak]

Holy Detonation Batman! There is serious combustion issues based on the carbon patterns on the heads and piston crowns. It looks like the lower plug on #3 was not firing.

What was the installed deck height on these pistons?

Why is the step down on the 98mm pistons so pronounced? that is a serious step down to the flat at the perimeter. Without a chamfer on the head to match the extra 1.5mm on each side I can see why there was so much detonation issues at the perimeter.

I think you are in good hands. I can not wait to see the results of putting new life into the engine.

Interesting observation. For comparison, here are the JE pistons I used in my build...seems to be less pronounced. These are 7.5/1 CR 100m slugs. Based on my calcs, deck height set at 1mm/.040" would achieve the advertised compression ratio. I ended up with slightly more deck, and slightly less CR.

[RarlyL8]

Wow, that is just a tragedy. Though it is no condolence I have heard many stories like this that never hit the web. Some of the biggest names out there have done some really shoddy work using unskilled labor. The money spent/wasted is staggering.

[Ken911]

This is exactly why I try to do everything myself. I have been building engines since I was 15 off and on i'll be 50 next year. No offense to any of the professionals on the board here a lot of shops do very good work then get big and hire unskilled people due to the small talent pool. When i have a problem with my car or something wasn't done correctly then i have only myself to blame and try to learn from the experience. A lot of guys arent lucky enough to have the tools or room to this work. It just kills me to see someone paid to have this done to them. Sorry just had to vent after seeing this.

[onboost]

WOW! Linc..

I knew it was bad, and that you were both pissed and disappointed, but I never expected it to be like this.. with as few-a-miles as you had on the build. Curses!!

Amazed at some of the carelessness and deceit involved. Like the anti-fouler WTF.. on a Porsche?

[QUOTE=willtel;5976430]Unreal. At least now we all know how we can make our plugs last longer.


You figured out what those are for and they were a popular bandaid solution in upright 170, 200, and 250 cubic inch inline 6 cylinder Ford motors from the sixties and seventies because the umbrella valve seals used in those engines would crack and fall apart after 20-30,000 miles causing oil burning and so much burnt oil deposits on the plugs they would stop firing.
Those things would sort of help delay the plugs from oil fouling as fast and also inadvertantly lowered compression a little.

Years ago when oxygen sensor bungs were hard to find I've taken one of those made for 14mm sparkplugs and cut the male threads off and welded it onto the exhaust pipe after the header collector and screwed an oxygen sensor into it. They make a good O2 sensor bung that way and end up cheaper than todays premade O2 sensor bungs.

[SCHNELE]

None of the shops that worked on my car used the so called cheap labor, they all boasted techs with decades of experience and in the case of John Truman he was working on Porsches before I was born. The thing is no one is ever really willing to be open about a bad experience and in an internet world people endorse shops with whom they have had only cursory encounters. I asked Chris to post everything here to make this process transparent for the benefit of us all, I should add that no shop has cut me back a check ever for all the screw ups on my car.

[SCHNELE]

I have gotten a couple of phone calls and I appreciate the kind words and sympathy that has been poured out it really means a lot.
