coopeR32 Posted February 13, 2013 Share Posted February 13, 2013 which plug did you drill out to access the main oil journal? I just enlarged my oil feeds to the crank.

AngryRB Posted February 17, 2013 Share Posted February 17, 2013 can anyone give me a link to a thread that talks about minimal rb30block prep, just considering the cost on a budget..

SilverECR33 Posted February 21, 2013 Share Posted February 21, 2013 while mine was out the second time, we decided to do it too. however we also port matched the rear oil galleries as they are smaller on the 30. ended up lookin like this.

Shoota_77 Posted February 21, 2013 Share Posted February 21, 2013 Sexy! You've put a bit of work into that! Another tip my engine builder suggested (but I'm not sure I'll bother with or not) is a splash guard I guess you would call it that deflects the oil dropping down from the oil returns in the head to the side of the block so it doesn't drop onto the crank which creates further drag and additional oil mist in the crankcase. Makes sense I guess but where do you stop?? Link to comment https://www.sau.com.au/forums/topic/376890-my-rb30-block-prep/page/2/#findComment-6760606 Share on other sites More sharing options...
SilverECR33 Posted February 22, 2013 Share Posted February 22, 2013 thanks, yea the cleanup work was done by my mate Grootie from Grooties Race and Resto in Adelaide. the rb30 center returns hug the wall as you can see in the picture next to the bottom of the piston bores, and dont present as much as a problem as the rear galleries do, as the center area is a tornado of oil anyhow due to the spray from out of the sides of the bearings. the rear galleries however dump most of the oil back into the sump and on serious drag cars or circuit cars, presents an issue wh ere the oil is actually going back up those rear galleries, therefore not allowing the oil to flow down there fast enough. Those cards you were talkin about would be best placed there , we thought about doing it, but its a prick of a place to try and weld in some cards/baffles, but it can be done. I think it would present the best payoff/benifit, i guess, for the oil control issue in these RB motors Im sure this has been done to death previously, and ps im not a mechanic, just a hobbyist. cheers.

Had trouble sending from my phone, hence the double post, but BEARING SPINNER was telling SHOOTA that "its called a windage tray" . . .but thats not what SHOOTA was talking about a windage tray is in place to stop the crank from whipping up the oil in the sump(as it spins) and possibly away from the oil pickup SHOOTA was asking about baffles that deflect the draining oil from dropping onto the crank Link to comment https://www.sau.com.au/forums/topic/376890-my-rb30-block-prep/page/2/#findComment-7122542 Share on other sites More sharing options...
