As for function, they're great. The idea makes sense and they work. Its this whole thing about them coming loose that gets people nervous. We talked before about securing them with a pin or something from the end of the sleeve. I might do that for insurance after hearing this story about Kahren.

Where can I see these pictures of this failure. And can you just eliminate them for good by taking them out, or will this cause problems?

Also, should I send them out with the block to have the shop put them in when I have the engine rebuilt, or should I do them myself so that I know that they were done right?

There is a pin in the FAQ section that shows the failure with the sleeves from another engine builder you can check out. I don't think he used any adhesive or anything to secure them though. You don't need to send them with your shortblock to a shop. If you take your intake manifolds off, you can pull them right out.

and here i am, the sleeves are a good idea if they are tack welded or were actaulyl really pressed in there, locktite doest belong in such places, i trusted the manufacturere of these and they were pre installed for me. i personally sent these out to Rob and got them back ready to install. there were no further directions given and i wasnt even thinking twice if anythign would come undone. my ports werent functioning right at the time, since i was gonn rip apprat all those intake manifolds and get to the sleeves i though, i might as well order the pineapple sleeves at the same time to get that last bit of power from the engine. oh and they give about 4 hp according to rob, not sure if this is at the wheels or not but thats what he told me.

if u are lookign to get more power, just take the sleeves all out completely, if u calculate the surface area witht the sleeve in and with it out its exactly 50% diffrence so guess what, uwill get pretty much that much more air flowign thru there. yes u do loose the low end, but do u really care in a slow NA anyway, and that top end power will be worth it anyway. if u want low end thik of a diffrent way to alter port opening, the 6 port sleeve is a horrible idea atlest imo.
