Re: My poopy conquest and it's cracked block
 

Well, I'm taking it in tomorrow to get hot tanked and magnafluxed, so today would be the day for checking it ourselves. Otherwise I might have the shop check it since it's there anyway. We'll see and I'll let you know.

Re: My poopy conquest and it's cracked block
 

Got the anchor out today.

This is a good pic of the crack going toward the back of the engine.

I really don't want to get new ARP studs, but I might have to since I used 'em to hoist the engine out, lol.

Re: My poopy conquest and it's cracked block
 

Please take pictures of your pistons ring lands.

G54B cam gear holder > all. That little tab is the best part of the motor.

Re: My poopy conquest and it's cracked block
 

I will.
Yeah, they knew we'd be taking them apart sooner or later. That's why they put such wide tool trays on the inner fenders.

Re: My poopy conquest and it's cracked block
 

Nice guess! This is a major bummer:

Only one piston was cracked, but they all have varying degrees of wear on the thrust sides. Enough that I am concerned. But I have already made up my mind to get new pistons. Sad. Plus one of my rods is all discolored on the small end like it was torched. I had one rod "repaired" or refreshed or something when I had it all machined, so I don't know if it's from that or not.

Also, the #1 rod bearing chamfered itself on the rearward edge by rubbing on the crank. My guess there is that when they machined the crank, they kindof forgot to go all the way to the end of the journal. I now have to get the crank checked out. I had seen some metal flecks in the oil a time or two before and didn't worry, but now I know what was doing it. Lame.

This is going to cost way more and take way longer than I thought.

Re: My poopy conquest and it's cracked block
 

Which piston was that? A little less timing on pump gas next time, that sucks.

Re: My poopy conquest and it's cracked block
 

Number 4. And yeah, I will definately take out timing, and this build is going to be done much more competently than the last one.

Re: My poopy conquest and it's cracked block
 

4G6X time. :nod:

Re: My poopy conquest and it's cracked block
 

I could probably make money on a 4g63 swap.

Re: My poopy conquest and it's cracked block
 

Yep, time to switch motors.

Re: My poopy conquest and it's cracked block
 

too soon though. I have to make a lot of power on this setup for this year. Next winter maybe I'll switch to another engine if any problems arise.

A good tune is all it will take.

Re: My poopy conquest and it's cracked block
 

sounds good man, i wish you all the best!

P.S. Go forged!

Re: My poopy conquest and it's cracked block
 

I need 500 bucks for a set 'o forged pistons. Pretty steep. I might go the broke route with Hypers again, and run like 12 degrees instead of 17. *oops*

Re: My poopy conquest and it's cracked block
 

Hey man,
I have a built 2.6L here at the shop we need to sell it,
has about 5000 on it, asking 600 firm,
let me know,
Jesse-

Re: My poopy conquest and it's cracked block
 

It has forged pistons, shot peened rods, new bearings etc. also has a crank trigger set up off of a 83 crankpully,

Re: My poopy conquest and it's cracked block
 

Wow, most convenient deal ever? Fatty you got lucky.

Re: My poopy conquest and it's cracked block
 

Agreed!

Re: My poopy conquest and it's cracked block
 

Thats a great deal. Also consider less timing then that until it sees a dyno just to be safe. Did you sync the ignition timing?

Re: My poopy conquest and it's cracked block
 

Fuck yeah, and 17* timing? you been away too long.

Good luck and be uber safe this time.

Re: My poopy conquest and it's cracked block
 

Well... I can tune it, before you start it up this time if you'd like :).

Tough luck on that engine, but what a convinent deal that just came up!

Re: My poopy conquest and it's cracked block
 

Wow, holy crap, I will jump on that. Let me finger out my money, and I'll send you a PM, but I'm about a million percent sure I'll get it.

And yeah, the timing was synced, but not at high RPM (didn't adjust for drift, or check for it, for that matter). Like I said, this time will be done right.

Re: My poopy conquest and it's cracked block
 

Ouch. Well it happens to the best and the worst of us. Thats why I started with piggybacks and then training, then standalones. Everytime I've had to learn something knew it has been on a car I am 100% responsible for.

Timing drift/sync will eat you up at higher rpm. Plus in the beginning I know you were having driveability issues with huge AFR swings as well. Take it as a learning experience and be thankful it wasn't on a REALLY EXPENSIVE motor :).

Re: My poopy conquest and it's cracked block
 

Yeah, most of those driveability issues were my fault and I got them pretty much figured out. It's all good in the hood for now. :) Thanks for all your replies everyone.
