Hi Captain

Why don't you re liner the block to get rid of the poor design looks like the T6 is no better then a 2.3 T5

Russ

Yeah my engine did something kind of like that... went through the cylinder though and torched the metal out on to the cooling jacket walls.

and this

My guess is a hot spot in the cylinder coupled with a HG fail. No audible detonation. 23-24 psi on a 16t running around 11-12:1 afr.

Hi 550

Sorry to see this i no what thats like we must start a liner split pic thread lol what ex manifold have you got ??

Hi Russ,

Yeah the T6 is not any bettere than the 2.3 T5. It's exactly the same thing just with an extra cylinder stuck on.

I am going to add some reinfircing material on my other engine to make the deck "semi closed".

I hope you will document that - I'd like to see the process & result.

I was running a stock manifold. I'm sure that didn't help. haha

Oh i hope you get it sorted ok

If you want my advise which i doubt you need but i would re liner the block like i had to do with much stronger and thicker ones then volvo and also get rid of the slit between the bores and it lasts well so far.............

I agree- sleeving is the only true silver bullet. But, unfortunately I am cheap and I like experimenting so I'll probably try reinforcing it first. :lol:

OK, I've read the string, and looked at the photos, and if indeed the crack is large enough to allow the sleeve to move, I'm at a lose as to why you would make any attempt to repair it. Any idea as to how far that crack travels? The vertical slits only go down around an inch. It's my understanding that they are there to provide an extrusion affect for the metal in the headgasket, providing a superior seal between cylinders. Filling them would have a negative effect in my opinion. Unless you could remove the entire liner, drill and pin the crack to prevent it from propagating, then resleeving, sounds like a lot of work and more expensive than finding a JY block to replace it.

I am reinforcing a healthy, non-cracked block. I am aware of the fact that the block pictured is monkeyed and not worth fixing. ;)

I am not filling those slits either, that would not help anything. You'll understand when i do it.

Looking forward to pics. Just read through the TB version - a tad more technical info in that one :D

Yeah it's too time consuming to get into the details on both boards, I do like VS but I'm more used to thinking things through via tbricks.

Anyways I pulled the head off of my old motor and man it looks fantastic in there. There are 4 exhaust vales and 2 intake valves I am super super in love with due to the previous tbelt skipping incident, but otherwise it all looks pristine, even the bore that I ghetto-honed and threw a new piston in. :lol:
