Rb26/30 Lifting Head Need Help

[luke gtr]

Mine didn't.

Ran fine until I spun bearings.

and I'll be looking at better quality than a bunnigs washer.

going to the local bolt master to see if the have any high tensile washers in double thickness.

Obviously not a bunnings washer. Another Nissan head bolt washer is what a sensible person would use.

Yeh I have a full set of 26 head bolt washers that I will run. I'll try just dual washers first with another HG, see how things go from there.

Seems odd how some people have this issue and others don't. Any idea if your block came from an R31 or a VL?

And report back please

thought about this.

Depending on block machining, head machining, and gasket thickness used, will depend if they just clear, or just foul.

the more you skim off, and thinner the gasket, the more likely to need the extra washer.

I have a r31 series 3 block and had 2mm skimmed of the 25 head and using 1 washer holding 21psi with no issue

[luke gtr]

I belive the issue may lye with using the 25 studs with the 26 head.

had 1 nut just touching the end of the thread upon disassembly of mine.

Thought I would report back guys in-case this help anyone else out. I ended up running dual washers, standard 26 washers plus the ARP washers. Standard OEM 26 head gasket, and went another 15 ft/lb over on the torque. So far it's done 2 track days and a few runs here and there, no signs of pushing coolant and comp/leak down test done the other day was all good. Holding about 26psi fine.

Big thanks to all those that commented, and especially those that hinted about the dual washers.

Cheers.

Nice to see an easy fix after so many problems. Bit of a weird one but got there in the end

How come u didnt use a multi layer steel gasket mate?

I was concerned that the block face may have been out slightly, as I wasn't sure the washers would be the fix at the time, hence I decided to go composite thinking I would have better success that way if the block was out . That and other people have reported pretty good success with them after only doing ARP studs on standard NEO's and the like, similar boost to what I am running.

I suppose time will tell if that was a bad decision, I did work it hard at both track days but with only about 5 mins rest time at each event.
