Oil drain for twins I was over in TallTims twin GT35 build asking about oil feed/drain lines as I'm in the middle of a similar build. I've figured out that I can use -4AN lines off a tee from the oil pressure fitting for the feeds. As for the drains, he used two -10AN lines into the fuel pump block off plate. I have a later ('96) block so no plate. Is the oil pan my only option? Can I run a y fitting into the pan from the two lines or will that back up? Or is there enough real estate to put two 1/2" holes above the drain plug. I'd prefer not to yank the motor but... Thanks. Here's the work in progress: https://cimg1.ibsrv.net/gimg/www.thi...b67cbedc86.jpg |
Re: Oil drain for twins I dont think that would have gravity drained to a plate to begin with atleast not the driver side turbo. Maybe but not ideal You will want to drain to oil pan, ideally one per side. Or to a scavenge pump and pump to valve cover |
Re: Oil drain for twins Thanks, So I'll scrap the idea of running a two into one y fitting into the oil pan. I can't see much room on the passenger side ( to get a drill in there) but on the drivers' side of the pan it looks OK. Maybe a 90 degree drill. Just drill, tap and thread a fitting in. Sorry, that's a question, I've tapped other thicker stuff before but nothing as thin as a pan. |
Re: Oil drain for twins Fitting near front of pan may work with a 2 into 1 drain just make sure both are as downward an angle as possible. I never tapped a pan lol just welded fittings |
Re: Oil drain for twins I like the welded fittings idea better but I take it that means pulling the pan... |

Re: Oil drain for twins So the consensus being drill and tap at your own risk. And don't complain when it leaks... For a car that gets so little mileage, I think I'll try that route for starters with the plan to put weld in bungs next time the engine comes out. And that'll be when I get brave and turn up the boost. |

I'm not that concerned about leaks as much as I am metal getting into the oil. -- Joe |
Re: Oil drain for twins Yeah i was gonna say try right stuff to seal it or epoxy |
Re: Oil drain for twins Got it, thanks for the help guys. I'll figure out all the hose and fittings I need for the feed/drains,order that, then start working on the new manual brake setup. Brian |
