Hey all,

Upon recent inspection i have found that the nuts securing my turbo to manifold have loosened themselves off and the turbo-manifold flange gasket has blown apart. I know this has been a problem for some owners, but was just wondering if anybody has fixed it and prevented it from re-occuring and whether anybody knows the cause of it?

Also would like to know where i can get a flange gasket in Adelaide, ie to repco, etc sell them and how much they are worth.

Also wondering whether anyone runs 0 or 5w synthetic oil as I am leaning towards 10w at the moment due to the age of the RB20

Thanks in advance

Dwayne

Dwayne,

Firstly ( and this is only my opinion ), if you're going to remove the turbo to do the gasket, do yourself a favour and pull the exhaust manifold off the head, replace any damaged / broken studs ( almost every RB seems to break the rear most manifold stud in time ) and the manifold gasket.

As for the nuts holding the turbo on, just make sure that you use new / genuine lock tabs and gasket when putting the turbo back on ( gasket can be re-used a few times if OK ) and all should stay tight. Also make sure the studs are OK. Most of the cars that I've worked on that have had this problem have an old twisted set of lock tabs, are poorly bent / locking or none fitted at all.

Again my opinion, use nissan genuine parts unless something better is available. It's worth spending a little bit extra to get quality ! ( I can't stand people who spend $600 on rice gear but won't spend an extra $10 to buy a quality gaskt !! <_< )

Not touching the oil subject. Sure to cause debate :( I know what I use in my car and those that I service and I'm happy :)

Hope that helps.

Thanks FAT32,

I was going to check the manifold as well as I have heard of them breaking studs etc, which won't be a problem as I am a diesel mechanic myself. I thought I would just check first before checking genuine prices incase Nissan charge something like $50000 for a gasket like they do most other parts. I think i will go with 10w synthetic oil next should be fine

Cheers again

Dwayne

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
