Really low oil pressure

[latof]

My friend rebuilt a 6 bolt block for the one that blew up in my 95 gsx. So we swapped out the engine, and now i have really low oil pressure. He says he is sure that he forgot to do something with the bolt to the crankshaft that allows oil to flow through it. I was wondering what that bolt is called, and what i would have to do to get at it and what to do to it in order to make sure my bearings don't wear on the crank and blow the engine up again. please post pictures if you have any idea what i am talking about.

This Sounds Like Its Going To Be A Problem. Is He Referring to The Main Bearing Cap Bolts Rod Bolts. . . .a little bit more detail will help pin point the potential problem a lot faster.

Bearings installed wrong or blocking oil flow will INCREASE oil pressure, sounds like you have a differant problem.

[blackrosenova400]

Do you have a balance shaft elimination? Maybe he forgot to install the block off bearings or rotate the old bearings?

[latof]

Yeah, the balance shaft is eliminated. I cant remember if he said the bearing just needs to be rotated, or if he forgot to put in the block off bearing. Do you think it's possible to jam a dowel pin into the hole to block it off? if so, does anybody know the exact diameter of the hole? If you do, i could just machine a pin to fit into it. Or if i could machine a large plug to just shove into the place of where the balance shaft goes into.

what are you going by to determine low oil pressure?

Just slap on a BB turbo.

No need for a restrictor! ZING!

I was going by the oil pressure gauge, and I know the connection is good so it wasn't that. But I solved the problem in under 4 hours. All I had to do was take off the front bumper cover, front mount, radiator, and alternator. Then I removed the threaded phillips bolt from the block, then i just used a drill bit just under .223" in diameter at 2.3" long and tapped it in the bearing hole, using the back end of the bit to go into the oil hole. Then I put the threaded bolt back in, and put everything back together, and now everything is running smooth. But i would suggest using an actual dowel at a little over 2.4" just to be safe, I know im safe with what I used, but just to be safer, i would go with a little longer. The phillips bolt was kind of stripped, but I was able to get the phillips bolt out by using a ratcheting phillips screw driver that when you hit it with a hammer, it ratchets at the same time (that tool saved me a lot of time but i wish i knew what the actual name for it is called :/)

impact screwdriver, thank you s1ngletracker

Clever. Usually you just pound out the bearings for the balance shafts out (the balance shaft makes a nice punch for pressing them out). Then rotate them so the oiling holes don't line up any more.

[latof]

Yeah, but the balance shaft wasn't assembled with the engine, and my friend forgot to put the bearing back in, but luckily all i had to do only took 4 hours and the sacrifice of a drill bit with a diameter just under .223" without having to take all the crap of the front of the block.
