jamal Posted June 15, 2008 Share Posted June 15, 2008 It's easier with something like this: Quote Link to comment Share on other sites More sharing options...
idosubaru Posted December 20, 2008 Share Posted December 20, 2008 Skip - any word on this? How much to have it done or how brutal was it to do yourself? I just picked up an H6 legacy and am probably not too far from a spark plug change. Quote Link to comment Share on other sites More sharing options...
Skip Posted December 20, 2008 Author Share Posted December 20, 2008 Gary, sorry no I have not done it yet. We have been traveling in our travel trailer/truck and have not put many miles on it since I posted. I did find several pictorial procedures for the operation on the outback forum. I did buy the plugs from a link on that forum. The socket jamal shows looks like a winner. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 20, 2008 Share Posted December 20, 2008 Use a socket(3/4?) on the hex shaped top of the spark plug socket instead of a common extension or swivel. This gives you just about perfect spacing to clear the frame rail. The socket needs to be rotated into the hole, taking advantage of the oval shape. Same with the plug wire ends. Remove the air intake tube, the battery, and the washer resevior. Makes it much easier. Also its good to use some di-electric grease in you're socket when installing the new plugs, otherwise the rubber sleeve can stay stuck to inside the hole. Or, glue you're rubber sleeve into the socket to be sure it's tight, or just remove it. You don't want that sleeve stuck in the hole. PITA!! This will prevent the plug wires from going on.

Skip Posted December 20, 2008 Author Share Posted December 20, 2008 Gloyale has an excellent tip I believe this is what he is describing. I could not get the rubber plug retainer out of the socket. Mine has coil packs over the spark plugs that must be removed. Quote Link to comment Share on other sites More sharing options...
J A Blazer Posted December 20, 2008 Share Posted December 20, 2008 My mechanic told me that in order to change the plugs on an H6 it is usually necessary to remove the engine mount bolts and lift the engine slightly in order to permit the spark plug socket wrench to get past the frame rails.

Skip Posted December 20, 2008 Author Share Posted December 20, 2008 sorry Mr. Blazer sir, that is just not true. Although I have not done it, I did give it a close examination. Removing the parts Gloyale mention helps, soaking the coil pack hold down bolts in Deep Creep or similar is also mandatory. Getting at them from down under -yep. But lifting the engine, don't think so. Quote Link to comment Share on other sites More sharing options...

Skip Posted December 20, 2008 Author Share Posted December 20, 2008 yes EVO, they are sweet pieces of kit But for $115???? Quote Link to comment Share on other sites More sharing options...
davebugs Posted December 20, 2008 Share Posted December 20, 2008 yes EVO, they are sweet pieces of kitBut for $115???? Breaking news!!!! Sears (and apparently Sears only) has a Gearwrench set of 3/8 and 1/4 drive swivels just like that. I had just paid 83.00 for a Snap-on 1/4 swivel that I like for torque converter bolts. The set appears to be only at Sears and is 59.99 - what a deal. Looks like the exact same as the snap-on that I have. Dave Quote Link to comment Share on other sites More sharing options...
davebugs Posted December 20, 2008 Share Posted December 20, 2008 Link to Sears. http://www.sears.com/shc/s/p_10153_12605_00910172000P FYI I looked at the gearwrench website and had my local parts store (that handles Gearwrench) see if they could get them for me and they couldn't. So Sears seems like the place for this - atleast for now. Dave Quote Link to comment Share on other sites More sharing options...

johnceggleston Posted January 5, 2012 Share Posted January 5, 2012 (edited) bringing back this dinosaur for related info. VALVE cover gaskets and plug gap. i picked up an '01 H6 VDC w/156k miles and a bad / dead auto trans for $500. i swapped out the trans, don't ask me what i paid for it, but safe to say way more than the car. now the reason for this post, removing the valve covers and installing new spark plugs. this is more than an adventure. it's a b1tch. the lower rear corner bolt cannot be reached easily. and once you do reach it your wrench swing is limited to about 15 degrees. so it is very slow. but the reason for my post, i found some RTV type stuff on the passenger side valve cover gasket. is this standard?????? should i do the same?? i feel like the gasket should seal with out any additional ''stuff''. but this is my first H6 rocker gasket. and second, what is the gap on the spark plugs????? thanks, john Edited January 6, 2012 by johnceggleston Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted January 6, 2012 Share Posted January 6, 2012 Don't know about the goop, but the proper plugs are pre-gapped. Platinum and other pin-electrode plugs cannot be reliably gapped. Dave Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted January 6, 2012 Share Posted January 6, 2012 that's always been my experience with plugs, but i just don't want to have to do this again any time soon. Quote Link to comment Share on other sites More sharing options...

If you decide to check the gap before installation, be VERY careful as I've read it is easy to damage the iridium/platinum tip. Quote Link to comment Share on other sites More sharing options...
