Gary M Posted June 20, 2022 Share Posted June 20, 2022 Here is Fumoto info. https://www.fumotousa.com/?target=level_front_page Looks like lower drain is 18mm and side drain is 22mm. Link to comment Share on other sites More sharing options...
CaymanXL Posted June 20, 2022 Author Share Posted June 20, 2022 Thanks For your help! Looks like I need the 18mm Link to comment Share on other sites More sharing options...
cbr046 Posted June 20, 2022 Share Posted June 20, 2022 The Fumoto, or any drain valve that isn't protected from road debris, scare me. I had one event where the ruts were deep (surprised the stairs and gen pipe made it out alive). The thought of unknowingly losing engine oil . . . . But the ValvoMax and Stahlbus look a little more robust (no valve to knock off) and still offer a clean oil change. Just a thought. https://www.amazon.com/ValvoMax-Oil-Drain-Valve-M18-1-50/dp/B077ZJYTFF/ - bob Link to comment Share on other sites More sharing options...

They used to be sold under the FRAM name, and were a LOT less expensive then. Link to comment Share on other sites More sharing options...
Cubflyer Posted June 20, 2022 Share Posted June 20, 2022 Quick drains are great! Really handy..... but since I do my own oil changes and they seem to be once a year event, I'm staying with the good old fashion 'plug'. Mine has a built-in magnet, quickest, best way to know if there is a problem in your engine. Easier than cutting the filter open and faster than waiting for an oil sample result. If you are not doing your own oil changes, WHY would you make it easier for someone else?? And risk it's failure (in many ways.. already mentioned here)???

dl_racing427 Posted June 21, 2022 Share Posted June 21, 2022 Ken, It also prevents wear on the pan threads, and prevents some grease monkey from overtightening the plug and pulling the threads out completely. In over 3 decades of using these valves, I've NEVER had a problem with one of them. Link to comment Share on other sites More sharing options...
CaymanXL Posted June 22, 2022 Author Share Posted June 22, 2022 I too have used them for years without issue. Just looking for the correct fit. Trying to figure out just how similar this ISB is to the ones I have had in pickups. Link to comment Share on other sites More sharing options...
Gary M Posted June 22, 2022 Share Posted June 22, 2022 According to info I have found your lower drain is M18x1.5 and your upper side is M22x1.5.

tmw188 Posted June 22, 2022 Share Posted June 22, 2022 (edited) What is the upper side drain for, draining off a possible overfill? I don’t recall seeing two on my 8.3 Edited June 22, 2022 by tmw188 Link to comment Share on other sites More sharing options...

Based on the fact that I change my own oil, the 'grease monkey' is not using an impact gun to remove or install the plug, the threads are not going to wear out or get stripped or cross threaded. (One trip to Jiffy Lube wiped out the threads of a pan that I had done the oil changes on for 180k miles back when we changed oil every 3k miles so I know that pain is real). I also safety wire my drain plug.... guess I am OCD. Ken Link to comment Share on other sites More sharing options...
CaymanXL Posted June 23, 2022 Author Share Posted June 23, 2022 My reason to install is to be able to stop the flow when draining, doing my own oil change. I have a couple different drain pans but neither will hold all 17ish quarts. 1 Link to comment Share on other sites More sharing options...
Martinvz Posted June 23, 2022 Share Posted June 23, 2022 I agree with Bob regarding using Stahlbus. I have installed on on my GM gas engine and it works very well, no mess. Now to find a solution to the mess an oil filter makes …. 1 Link to comment Share on other sites More sharing options...
