Title: Done split another cylinder wall darn it to heck!
Post by: reddevil on March 07, 2010, 02:36:38 AM
At PIR again tonight, this time I brought the family out.

Swapped back to the 205/55/16 crap tires....

Pull a 12.55 @ 117.69 with a 2.1 60'... poop...

Wife wants to leave. C'mon, watch one more please?

I nail it... Its flipping perfect.

Then the #4 (I am betting) cylinder wall splits in 4th gear...... I keep the pedal to the metal...

Pull over at the end of the track, determine, yes, there is WATER everywhere, not oil. So I know I split the cylinder wall... Drive down the return lane and park.

My friend I was racing pulls up after getting his time slip (why would I want mine? I sucked ALL of 4th gear.)

"I think you want this"

60' 1.940
1/8 7.943
mph 91.75
1/4 12.499
mph 96.99

IF only the motor hadn't popped.  What if, what if, what if.......

Can we get a look at the pistons, you still having issues with tuning?

Pistons should be fine.

I am betting the crack started on a heavy pull a month or so ago and I had some bad det on pump gas.

Post by: Eggylshatch on March 07, 2010, 04:01:25 PM
you need a sleeved block?  and to stop detonating on pump gas, eh?  I just hate to see this beast down, it should be shredding the streets.  Is it still twin charged or are you just running a turbo now?

Post by: ratcityrex on March 07, 2010, 04:08:32 PM
Dude what moter is this now? Like your 5th one? I would just opt for a sleaved block. But fuck, that "what if" could have been good if it would have had together

This is my family wagon, not the twincharged wagon.

Yeah, I would like a sleeved block, but thats money I do not have....

This failure is in a section of the block that happens to even STI blocks...

This is the 2nd time I have split a cylinder wall.

This motor has had 3 sets of pistons in about 13-14 months...

I am going to fill the weak section in with a pin for support this time.

Hum cant wait to see the build thread on that one.

You're like the hotrex of subies, except you actually make it to the track.

I'm impressed at the timeslip but fuck - at least spend a few bones on a starters accounting class. You will learn that even with "future value" of money figured in, the interest paid on a small loan will completely offset the time & money replacing pistons & blocks. Even if they are cheap for you.


Even cheap Honda people plunk done the money once they realize there's a chance they'll be splitting sleeves.

Pinning is a bad idea, it does not work as advertised.  Cylinder balloons under cyl pressure and the pin... you get the idea.  The sleeve, instead of cracking horizontally, will crack at a right angle due to the pin and then go from there.

I'd do a 1.5-2.0" band of devcon right around the point the sleeve likes to crack.

I dont believe in block posting, filiiing, or blockguards.   The sleeve cracking is a function of the strength of the sleeve, attempting to stop it from moving wont stop it from happening.

but it may slow it down.  it can propogate somewhere else at a higher pressure level. 


DEVCON ftw

   I dont agree with that.  It wont slow it down at all. If anything the change in the cooling of the cylinders/head will create hotspots increasing the likelyhood of cracking a sleeve.

Disagree, sort of.  I've seen it hold together very well in a couple motors, and the two the sleeves cracked in were still driveable enough that you could cruise the car home - while cracked they don't seperate and so coolant doesn't go anywhere, it just acts like a mild broken ring with oil smoke everywhere.  $35 and thirty minutes to devcon, vs $60-150 tow bill and 1-2.5 hours waiting on the truck.

Big caveat, most people pour their blocks too high - cylinder expands and splits lower down, and coolant flow at the top of the cylinder where it's hottest is important.

Well, I had a new motor in 4 days later, but it was making some awful noises....


Time went by....


I found the issue, dealt with it.....

Dailydevil is driving again....

But for now?  Its a fucking transportation wagon....   I need to store up some money if I need to build a real motor again!  My daily car is 8mpg Econoline with no seats for the kids....

Some would disagree on there not being room for kids...

 If you are not breaking part than your not making power. ;)

I love the clean white trash look of that work van, sir.  You did a wood job, very nice.

You know it was probably more money for that piece of wood, than it would have been to go get a bumper from a wrecking yard....lol

Still digging the white trash look thought!

Should have at least used pressure treated.
