Almost finished with my $52 weld-el manifold for my GRM $2010 car and realized that I may have dropped the oil drain a little lower than I would have liked. I'm trying to use some of the AN fittings and steel line I got as a packaged deal with the turbo on craigslist, but may have to go to some push on stuff to get a little extra room. The route doesnt run uphill, but it does get pretty close to horizontal. I'm also probably pretty close to the min bend radius on the hose, but I'm not as concerned about the it breaking as I am the drain function itself.

What do ya'll think, should I be concerned?

 

In my limited experience, I want to say no, don't be worried. Wait for that 2nd, 3rd, and 4th opinion though. You should be fine for the drag races, it's the autocross I'd be worried about. Won't take much g-forces to start pushing oil back up a bit on right hand turns. Who knows though.

That's one hell of a rust bucket ya got there.

 

thanks for the input - I hope to be able to take it out for some track events as well, so the hard right issue is something of a concern, but we'll see.

Fortunately it's not as much of a rust bucket as that core support would indicate. It's a 90 that I bought for $400 because it had no battery and a bad ignition coil - I35 is fun on 2 cylinders - and it's been in a pretty good front end hit. Whoever "repaired" it neglected to put any paint on after welding parts of it.

 

Thats a pretty damn shallow angle, but Im gonna say that it will probably be alright since its a pretty big drain line.

Ive seen people get away with worse

 

Doubt it will be a problem. If you had that line full of oil it is going to take a pretty large sustained G load for a long time to actually hold it in there, and with the pressurized oil going into the turbo, it will try to force its way out if it starts backing up in the line. AFAIK the reason you see people worried about drain lines with things like an STS setup is that the constant puddling and backup of oil can result in the turbo allowing it past the seals and smoke/oil consumption results. Momentary slow downs in flow probably wont do that much if at all. If you get smoke out the exhaust on a sweeper with decent boost you will know why and you can worry about it then.

 

Good deal, thanks for the comments guys

 

Not sure if you have another set of 2 spares installed on the passenger side..but that must have been reeeeally fun driving on the interstate!

 

you will be fine I believe, as for spares... omg!

 

Mine is in the same place, with more of a kink. A restricter in the oil feed line will help reduce the chances of the problem you'll never have with this.

 

I like hustler's answer.

 

Looks fine to me, other than being a royal PITA to install/tighten.

 

heh - the spares are from a 94R i parted, not sure why he had 4. I sold the wheels that came on the car, but when I looked at the corded tires on them, I did think about going down I35... the spares make rolling it around real nice though.

Thanks Hustler - I picked up a restrictor, I'll throw it on if I start blowing smoke. prefer to keep it outta the budget for now.

Tim - it will require a strange order of operations, but I think I'll be ok mating the turbo to the manifold after the line is semi-tight

 

Looks good to me. Mine is very similar to that.
