Trogdor636 Posted February 9, 2013 Share Posted February 9, 2013 I'd put a bit of oil down around the plug, or even some penetrating lubricant like PB Blaster, and let it soak for a bit. When I swapped my friends plugs a few months ago, #6 was stuck like that. I put a bit of PB Blaster and just went real slowwwwww. Luckily it came out. It was a OEM plug (all the others were Bosch or something) and I'm guessing it had never been changed in its life. There was electrode, and it was a way bigger gap than either of my spark plug gappers could read. You can make out number 6 if you look through the upper plenum, it helped me a bit to see it when I put the plug socket on it, and to put the plug back in. On the WD21's there is actually a little notch in a pinch weld on the firewall, thats there for removing that plug I assume. Not sure if the R50 is the same. If you use an extension with a swivel/u joint, the plug is actually pretty easy to deal with. Link to comment Share on other sites More sharing options...
silverton Posted February 9, 2013 Share Posted February 9, 2013 It also helps to have high pressure air to blow the dirt that accumulates around the spark bolt as well, keeps it from falling in to the cylinder and mucking up the threads on the reinstallation.

ferrariowner123 Posted February 9, 2013 Share Posted February 9, 2013 (edited) Check and see under your back seat for the Nissan provided tools, some of its for spare tire replacement, but three of the tools are for spark plug changing. these saved my butt when i went to change the spark plugs on my car, ESPECIALLY number 6 But this photo i took of me doing my knock sensor change might help to give you a visual of how hidden spark 6 is. So this is taken right about where the harness would sit coming from the firewall (firewall is on the top left, front of the engine and car is going towards the bottom right), so pretty much reach down and its the only thing back there with a stud (So putting the boot back on it much easier) and the ONLY upward facing socket headed anything larger than 14MM But like i said, having the Nissan tools MAKES A WORLD OF A DIFFERENCE for this job. -Kyle EDIT: as far as getting them out, trodgor is right on the money, a small amount of PB at just the right angle and given time to soak, will be just the ticket. if not, start (Kidding, please don't do that) Edited February 9, 2013 by ferrariowner123 1 Link to comment Share on other sites More sharing options...
Tad Posted February 11, 2013 Share Posted February 11, 2013 We pulled the hood and used a mirror on a magnet to get at #6, made life much easier. Same deal as mentioned above, OEM plug, never been changed in 11 years, it was burned down to almost nothing. Link to comment Share on other sites More sharing options...
devonianwalk Posted February 11, 2013 Share Posted February 11, 2013 I just used a swivel socket and an eight inch extension. After you change it the first time you will realize how easy it really is to do. The trick was just figuring out how to get to it. Link to comment Share on other sites More sharing options...
bushnut Posted February 11, 2013 Author Share Posted February 11, 2013 I had was able to reach it but not turn it. I sprayed them (#5&6) with break free and I'll try again in a few days. Link to comment Share on other sites More sharing options...
zmagee Posted June 21, 2013 Share Posted June 21, 2013 I too was able to use an extender + swivel to reach #6 too Unfortunately - when I installed the new plug, the extender separated from the socket. That became one helluva fishing expedition - my family had to leave the house to escape the carnage. Some extra long needlenose pliers from Ace Hardware, and my sanity was restored.

Rebelord Posted June 21, 2013 Share Posted June 21, 2013 Those with R50s check your tool bag with your jack. Mine has the tools for the spark plugs. Works great Sent from smert fone Link to comment Share on other sites More sharing options...

I guess I was looking for a hole...then, after a few frustrating minutes, found the plug... Just goes to show how difficult it really is to find...

BrianD Posted November 16, 2014 Share Posted November 16, 2014 Great info! - I gotta do this soon - it's feeling sluggish when pressing the loud pedal - what plugs did U install? Anything I shud know about getting the wires off?..besides giving them a twist 1st? Do I need to get the special needle nose pliers for plug wires? Prolly shud change wires too - I'm almost at 300,000 km. Any suggestion on those? Where to get 'em cost? etc? Cheers! Link to comment Share on other sites More sharing options...
bushnut Posted November 16, 2014 Author Share Posted November 16, 2014 I got my NGK plugs at Canadian Tire for about $5.00ea. as for wires, haven't changed them yet, but I'd probably go to my local auto parts store. Link to comment Share on other sites More sharing options...
01Pathmaker Posted November 17, 2014 Share Posted November 17, 2014 Did plugs on my 01, not bad, just had to remove the throttle body to get to #4, used NGK Iridium. Just did the 96, NGK V Power plugs, NGK wires, Beck Arnley cap and rotor, #6 was a little tricky, runs like an animal (well for a 3.3 anyway) now.

fixinto Posted November 29, 2014 Share Posted November 29, 2014 Ohhh, the good ol number 6. I remember him. was probably original plug in mine as well, changed it while i was doing the valve cover gaskets, and again while i had the heads off the next year, figured why not. But i can in fact see how it would make fetal position weepage. =( Pat Link to comment Share on other sites More sharing options...
Megaton Posted November 29, 2014 Share Posted November 29, 2014 Be sure to put a little anti-sieze compound on the plug threads. It makes removal much easier. Best regards, Tim Link to comment Share on other sites More sharing options...
