Can You Hyrdolock Rb20/rb26 When Changing Injectors?

[Kwyjibo]

I'm just in the process of going from RB20 to RB26 injectors and looking at the 'Injector change' tutorial people are talking about hydrolocking their engines due to leaks past the o-rings but as far as I can tell these are all RB25's. Having a look at the top feed rail though I don't see how this would be possible on the RB20/26 due to leakage. As the rail itself sits on the top of the injectors fuel may leak out into the engine bay. The only way I can see any extra fuel flowing into the cylinder is if the upper seal leaks, the fuel runs along the outside of the injector(in the engine bay) and then back through the lower o-rings which would be very hard to get any more than a few mls of fuel in.

Am I right in thinking this?

Cheers,

When people talk about leaking injectors they can be talking about leaking through the injector into the cylinder, which would be the only way you could have hydrolock. So yeah the o rings have nothing to do with it.

BTW i wrote and injector change DIY yesterday HERE but from what you've said there is another. Do you have the URL?

The tutorial for RB25's is here here but it seems as if yours is the only one for RB26/RB20's.

People in the tutorial I linked seem to be talking about hyrdolocking due to fuel leaking past the o-rings. I imagine this is because of the side feed rail though as it seems like the rail itself connects to the head rather than just sitting on top of the injectors.
