I am gonna pre-mix on my s-4 engine. Just wondering if anyone sells plugs to plug the holes where the oil injectors used to be. I havent been able to find the right size bolt. The head always seems to hit something when trying to tighten it.

Bolts are the way to go. I don't remember the exact size I used, but basically found a nut that would work on the injectors, then took the nut to the hardware store to find a bolt to fit it. I ended up having to cut off a bit of the length of the bolt (clean up the threads!!), but other than that, I don't think I did anything else other than use some thread sealant and tightened it down. If the bolt head is hitting something, see if you can find a smaller bolt head. You could always go w/ a threaded plug if you can find the right size. Plug that doesn't have a head, just a hole in the end for an allen wrench I mean.

Worse comes to worse, you could probably grind of a bit of the block material that is getting in the way -- I have a feeling you mean the little 'tab' that sticks up from the block -- you should be able to shave enough off to turn your bolt if you can't find anything else. Obviously grind the right thing if you choose to do that!!

Yup, the "square tab" part that comes off of the rotor housings is what I am reffering to where the bolt head is hitting. This is on a tII motor and I think I have the same problem with the bolt head hitting the lower intake manifold. Right now I have the bolts tightened Using the stock Spacer type things that have the tube sticking out where the oil lines once attatched. Don't know if this would cause a vacume leak or not. I did use thread sealant on the bolts. I don't like it this way and would like to change it. A plug using an allen wrench head would be sweet.
