Lee,,,unless you have a re-built motor thats not something I would recommend. Flushing an older motor will only start shortening your motors life. The small crud build up in older motors helps stop lifter,ring land and other interior parts from losing there bedded in tolerences.

Lee,

I'd go with what Neill Says.

Though,

You might consider doing a quick turnaround in oil AND Filter changes;

say @ only 1,000-2,000 Klm

I change my Filter EVERY time I change the oil.

5,000 klm...............cheap insurence.

To keep costs down, use a cheaper oil for the first change,

NOT Bottom of the shelf.

That oil would still be quite usable for other purposes.

Top-ups, or in my case,

use in the Donga, a Farmyard Hack-car.

Using flush additives your likely to loosen crud and get it stuck in oil galleries etc.

Just use a good quality synthetic oil, change it at the recommended intervals and overtime it will become cleaner from the extra detergents in synthetic oils.

The thing that I never understand is peoeple say don't use flush coz it might dislodge and clog stuff.

But if you never flush it, then it'll just build up more and more and more and then eventuall clog somethign else won't it?

PErhaps someone knowledgeable with engine building experience can comment on this

Provided the oil is changed at the correct intervals there will never ever be buildup in the engine in the first place.

Some people are just paranoid about maintenance and cause problems trying to rectify faults that never existed in the first place.

Yeah, but i meant if its used in engines that are full of crud, for eg. engines that have done 100,000km without an oil change you run the risk of it dislodging stuff and blocking galleries.

If your engine is not in this condition, why would you even consider using a flush treatment?

It goes back to what Neil said earlier, if you run it in an engine that doesn't have excess buildup, it can still potentially clean the smaller carbon buildup on pistons walls etc, that help with combustion cylinder sealing.

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
