Rb30det Trouble

[James_03]

Hey guys I am having trouble with a rb30det I have built. Basically when its idling it has an oil leak at the front of the motor which leaks down the front of the block above the water pump and below the front of the head it then runs down the front of the water pump. I suspect its coming from the head somewhere. Now as you rev the motor it gets worse and begins to dribble out.

I have just put hours of work into it trying to figure it out. It was running a GTR oil pump which I thought may have been causing it, but first I swapped the head over with another rb25 head I had thinking it may have been warped at the front. I put that head on with a new gasket and it leaks from exactly the same place. I have since today replaced the oil pump with a regular rb30 item. Again it leaks from exactly the same place. It leaks badly from the right of the head, and a little from the left.

It doesn't leak anywhere down the sides or rear of the block.

Any suggestions guys? Has anyone run into this before, really has me stumped and I would really appreciate any help I can get at all.

Cheers.

What headgasket are you using?

Is it the R32 or R33 head?

Has the block and head been skimmed?

[James_03]

Its the r33 vct head, head has been skimmed but block has not.

Using a monotorque rb30 head gasket but was previously running genuine nissan rb30.

did you block off the vct feed on the head

[RRob]

When you drilled the tensioner in did you hit an oil gallery?

[James_03]

Yeah the vct has been blocked off and no I have not hit a gallery where the tensioner goes.

Ill sort it out, I just thought someone may have experienced the same thing.
