so i guess my boost spiked cause when i tore everything apart i realized my boost controller was missing the bolt and ball and spring....







i hate my life

 

Damn dude sorry to hear that. Keep your head up, you are paving the way for all of us.

 

thanks man im trying to find acheap 2.0 block and head or 2.2motor and tranny or 2.4motor and tranny or something just to put there

 

Couldnt you get this block resleeved? I think Rod did it to his, of course you wouldnt have this problem anymore.....

 

nah its ******* done its the sleves and the wall or i could get the jbp sleeves :/ iono yet tho

 

oh my. wow.

hope mine doesnt look like that.

 

Wow. What cylinders are those?

 

Thats crazy, what are those white marks? Almost looks like you were getting a little valve slap. How much timing were you running?

 

#1 & #4

definitely had a piece of valve break off, that was rattling around in there, you can tell a piece was broken off inside because it's all over the piston top.

new block definitely. look on ebay. you can get a used LSJ for $1500, and a L61 for about $800

 

If it were me, i'd be buying the 2.4 block and getting things CUSTOM made for it because believe it or not people, with our cars, things are cheaper when they are custom made....well most things I have experienced anyway

 

damn I was waiting for those pics. Throw up one of the combustion chamber of cyl 4, I wanna see what damage has been done.
As I said before still have that spare motor laying around if you want to rebuild that. Just gonna owe me a cylinder head though

 

Thats also interesting that #1 and #4 both go at the same time. Are you using a return-style setup? You definately had what we (mechanical engineers) call instantaneous failure. Meaning this happened all at once as a result of brittle failure rather than repeated stresses causing the ultimate failure. This tells you that you werent for example running the boost too high over a long period of time, which confirms that you probably had a major spike in pressure which is the only thing common to both of those cylinders during the compression stroke. One more thing about the failure. If you pull the broken pieces out and they appear rough in texture where the break occured thats how you know its instantaneous brittle failure. If you ever get a break that is smooth, chances are you started with a ding, then a crack, then an ultimate failure. Just a little technical info for ya. I do failure analysis for a job, among other things.

 

jbweld that bitch!

 

**** that, duct tape ftw

 

That will do the trick





If that break is confined to the same area as RavenSS' engine then it is quite possible the JBP sleeves will actually take care of your problem with the block. That doesn't actually save you money as the install + sleeves are as expensive as a used engine, BUT you will have a much stronger cylinder wall should you have a similar occurance.

 

Thats what Im thinking. If you are going to be running this kind of HP youre gonna eventually have to do it anyways.

 

Better safe than sorry.

 

yeah iono i just want my car back lol

 

Brother, you're preaching to the choir!!!

 

was the piston to bore clearance checked on these or were they just thrown in? How about the ring gaps? Not hating on you, I'm just wondering.

 

Damn that sucks dude. Hope you get **** worked out.

 

i believe i read the bearing on the rods werent properly checked...i think thats what the problem was...bolt came loose and smacked the head

 

nah actually that wasnt the problem at all the rod bolts and bearings and clearance was fine i overboosted i mustve spiked cause the main pieces of my boost controller were gone and a piece of the sleve/wall went in to were the piston seats and was hitting the head and the top of the piston damaging both

 

Cant you just get new sleeves cause Darton Makes a set.

 

damn trix.. hope you get this beast back running man
