I am buildin my 1428 gs1150 motor with a top end oiler and 750 oil gears. Should i plug the stock oil passages in the block with set screws or leave them open?

I block them.  Do the cases on either side and the head in 4 places.  Base gasket leaking almost cost me a race and I switched to the dry block setup after that.

I don't block any of them & I also have NO leaks anywhere! Just do as OldPro said above. That's what I do. Ray.

I have been leaving the ports open as well and not really had any leak problems.   I have been using the yellow and gray snots and use new gaskets anytime it comes apart.    

I was having some problems with oil pressure.   Right now, with the ports open and the transmission plugged, at 9800 RPM I get about 50PSI.  After the shifts, the RPM drops to 8000 and the pressure drops just below 30 before it starts to climb again.    It's good enough for what I am doing but I suspect that if I were to run the block dry, the pressure would improve.

blocking any oil passage is scary--gs motors use oil volumn   -- not oil pressure. roller bearing crankshafts  use oil volumn  and plain bearing crankshafts use oil pressure  with the price of rocker arms -camshafts-valve guides not to mention a head. i wouldn't try it.

Scary?  I have known a lot of people who dry block them with no ill effects.    The transmission sits in oil so this is not a concern.   While the cams are not a roller, it's the turbo that requires the higher pressures.    Talking with Terry, the Garrett will be more sensitive to the pressure, so was best to nip this in the bud.

I've done it for several years now with no issues.  There are a couple guys that I race with that run dry blocks also with no issues.  One goes 8.teens while the other goes 8.40's.  All your doing is running the oil up thru the external lines instead of up thru the block.  Have you ever seen damage from this.

The only oiling issues I've ever had was an older top end oiler that had that sleeve installed that forced all the oil up to the head, back down the passages in the block, and then to the crank and tranny.  I ended up with a good bit of wrist pin galling from that.  I have about 300 passes on my motor going 9.30's-9.40's and riding it back every pass.

Any engine I have built for years is dry blocked, bracket to Pro Mod....... When good parts are used an assembled correctly no problems result from this..... There are many benefits to dry blocking...... After I do it one time for a customer an explain the benefits they are sold on it for life.... But to each there own...

I do think its funny  that Danno restricts his oil passages but not his nitrous nozzles.

BTW.... Wade ended up having another issue that the dry blocking didnt really cause, if he wants to share it may benefit others on here....

If you're going to use a top end oil set up I would recommend blocking off the passages that allow oil to go through the block. This will not affect oil flow to the crank as long as you don't open up the rocker arm oil holes. This also reduces the risk of oil leaks either side of the block while making sure there's good flow to the head. It's a win win deal.

If you use the sleeve style spacer manifold that blocks the other two holes because it captures the center hole like the Carolina set up is the studs are the only way for the oil to get to the crank bearings. What kind of oiler does he have does anyone know?
My signature was the same as Fasthouse's signature but then he changed it to some hoodoo voodoo stuff!
