czy18e Posted February 11, 2017 Share Posted February 11, 2017 See pics. Do most guys weld some more steel here for a good seal or consensus is it isn't needed? I have heard both but can't find any comments on sau about it? I have a good fabricator that I reckon can do it then obviously just get the block decked. Thoughts?

AngryRB Posted February 11, 2017 Share Posted February 11, 2017 I had my fabricator weld some more material around there and skim the head for reassurance, you don't want it leaking later on.

czy18e Posted February 11, 2017 Author Share Posted February 11, 2017 Thanks angry RB, do you know what method he used? Welding to cast iron can be tricky.

iruvyouskyrine Posted February 12, 2017 Share Posted February 12, 2017 RB25 gasket. Standard Nissan. Didn't do anything and it seals fine. 370kw and I give it an extremely hard time no leaks.

fikemoo Posted February 12, 2017 Share Posted February 12, 2017 I thought the done thing was 26 headgasket and make sure the oil gallery in the 25 head was blocked off. I'm now worried ad I'm in the process of doing mine lol Link to comment https://www.sau.com.au/forums/topic/469022-25-head-gasket-seal-onto-rb30-block-at-water-gallery/#findComment-7810787 Share on other sites More sharing options...
czy18e Posted February 13, 2017 Author Share Posted February 13, 2017 It's all good mate I spoke to my machinist and he said rb26 or 30 gasket. welding the block isn't required.
