I've got a set of platinum plugs and was told not to use fine sand paper on the firing tip as this knocks off the platinum tip and also not use a wire brush. So if you have fouled plugs how do you clean them? is there a solvent i can use or something (perhaps just petrol)?

I'm having missfiring problems as the car is running really rich and the car gets almost undrivable after a while so i'd like to clean the current fouling off it to give it a fresh start for when i have to drive it back to the mechanic.

Cheers,

Andrew

Hey GiJOr33

Might be a bit late now but there used to be small spark plug cleaners avialable that ran off your battery. These have a small sand blasting mechanism in them containing a very fine abrasive grit in them(zircon sand i think). I know cause i have one and the work a treat on platinium tiped plugs. I not long ago went through what you went through cause i have a big problem with throwing out perfectly good $26 plugs at a throw.

Hope this helps and contact me if you got any questions

fowled plug will clean up if heated.also if dropped in a stong cleaner.

normall put them into a pintara or a motor bike with twin plugs.or an old very reliable car that loves crook plugs.

with new cars on a car yard they get fowled so we put a old plug in to warm up the engine after a quick wipe or over night on bench the plugs are put into the hot motor with a air gap in the leads[not easy on skyline] to over load the coil so when it does spark it is at a higher temp.

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
