Guest Posted December 23, 2012 Share Posted December 23, 2012 <blockquote class="ipsBlockquote" data-author="wera803" data-cid="869329" data-time="1356267430"> <blockquote class="ipsBlockquote" data-author="slither" data-cid="869302" data-time="1356223883">I remember reading about these a few years ago on a Subaru forum, however one concern that came up was that the threads of the Fumoto stuck up past the oil pan, so when the oil was drained, there would always be a level of engine oil left at the bottom.<br /> <br /> Is this cause for concern?</blockquote> <br /> The only way to know for sure would be to pull the pan see how far the threads protrude (or do careful measuring). The threads of the pan stick down from the pan some, so I assume that would help.<br /> <br /> Every automotive engine I've ever pulled apart seems to have little pockets with oil sitting in them in multiple spots. There is no way to get every bit of old oil out of an engine from the drain plug, so I assume if there is a couple of ounces left in the pan, there isn't an issue. If there is a quart left in there, that is a different story, although I don't think that would be the case.</blockquote> <p>Fair enough, and for less than $30, I could justify it as an experiment. I already don't normally take the fairing off very far when changing the oil, this really would make things easier. Now, if only there were an easy way to control the dripping from the filter! </p> <p> </p> <p>I mean, I just bought a Raspberry Pi, a tiny, relatively slow computer the size of a credit card for ~$35, spent double that on SD card/keyboard/cables/power supplies, and hooked it up to a large TV. Nothing like running the command line on a 46" television! If that ain't an exercise in experimenting on things that may never serve a practical purpose other than a lot of hours entertaining me, I don't know what would be. <img class="bbc_emoticon" src="http://www.vfrdiscussion.com/forum/public/style_emoticons/default/smile.png" title=":smile:" /></p> <p> </p> <p>::EDIT::</p> <p>Ron Ayers doesn't have the '99 VFR800, and I just changed my oil last weekend, can anyone confirm the 12mmX1.5 drain bolt dimensions?</p> Link to comment Share on other sites More sharing options...
Member Contributer KevCarver Posted December 23, 2012 Member Contributer Share Posted December 23, 2012 Ron Ayers doesn't list the '99, but they do the '98. Same deal. And yes, 12 X 1.5 pitch. You can look at Service Honda, since they list all the years, but the picture quality isn't as clear. Link to comment Share on other sites More sharing options...
Member Contributer VFRMAN Posted April 27, 2014 Member Contributer Share Posted April 27, 2014 I think I over tightened the sump plug when I was changing the oil,it isn't leaking but when I was tightening it up I had it at a good tightness by hand with a small socket wrench,but I just gave it a bit too much pressure I think I felt it give slightly,I had a new crush washer on the sump bolt so I'm hoping it was just this washer bedding in, it only gave very slightly so I'm hoping I didn't damage the sump,it isn't leaking anyway so I'm good for another 4,000 miles anyway LOL. If I did strip the threads in the sump will the bolt unscrew next time and do I need a new sump or is a bigger bolt the easiest fix? Link to comment Share on other sites More sharing options...

Or try wrapping it in teflon tape and see if it holds .. if the tape method is still too lose.. get a next size up, stubby bolt.. borrow a tap that matches bolt. grease the tap. .. tap the pan. install new bolt. tada! youre done.

Member Contributer VFRMAN Posted April 28, 2014 Member Contributer Share Posted April 28, 2014 I wonder what the next size bolt is? maybe someone who's done this before can advise, a mechanic mate was telling me this evening that maybe what I felt was the new crush washer giving a little under the pressure,I'll see next oil change anyway,also he reckoned some silicone gasket seal on the bolt would help.

Member Contributer MBrane Posted April 28, 2014 Member Contributer Share Posted April 28, 2014 Stock drain plug is M12 1.5. Link to comment Share on other sites More sharing options...
Member Contributer gll429 Posted April 29, 2014 Member Contributer Share Posted April 29, 2014 Stock drain plug is M12 1.5. if thats stock.. you may be able to use a 1/2 inch tap and bolt. but more likely a 9/16th tap and bolt Link to comment Share on other sites More sharing options...
Member Contributer JZH Posted May 1, 2014 Member Contributer Share Posted May 1, 2014 I've seen M14 x 1.5 drain plugs on eBay, so at least the pitch would be the same. Of course, it's unlikely he's got an M14 x 1.5 tap in the tool box, so that'll cost some extra. Mixing Imperial and Metric makes me queasy...

Ciao, ging from 12 to 14 will most likely require drilling. vs just borrowing a very common tap . Link to comment Share on other sites More sharing options...
