Quick Question About Rb26

[Godzilla32]

Help me to rest easy! Can some of you confirm that the RB26 block is not dowled to the cylinder head?

Thanks,

Deren

She ain't doweled. There are two steel locator sleeves though.

And those three bloody 10mm bolts that hold the head to the block too!

I built mine awhile back but its been sitting for awhile. I just had a thought that maybe when the block was machined i hadn't replaced dowls as i thought it was strange that there was nothing to line it up with. What are the steel locators? I didnt have anything just used 2 bolts one in each end on opposite rows to line it up.. Are those steel locators removable for decking etc?

[GTRsean]

Yeah. Two steel sleeves that were in each end of the cylinder head. The bolt holes in the cylinder head where the sleeves go are slightly bigger than the rest of the holes.

Thats what I found when I pulled my eng apart. They just came out.

Found more used in the throttle mounts on the plenum too.

Yeah im familiar with the ones in the throttle bodies. It shouldnt matter that i didnt have them in should it? Its just to line it up. I made sure all the bolts were started and tightening down nicely so i assume its where its supposed to be.

[GTRsean]

Yeah, but I guess they may stop the head from walking that .000001 thou Lol.

It should be ok though.
