Default Oil line fittings, on block vs firewall.. ?

ok i've got my oil line setup,
but I set it up to have all the fittings and t's right at the feed source,
not sent off to the firewall first.

I've read in a few places that this is a "OH GASP NO AVOID" type of thing,
and was just wondering why?

I know that area is a pain in the *** to work in..
but I'm used to it. SO, does doing it this way cause some sort of undue stress causing leaks or something?

Everything will have the proper thread pattern, and will be wrapped with teflon tape.

So you have it T'ed at the block? Do you have some sort of oil pressure sender on there too? If so, it may be a lot of weight on there and could break off causing a big problem. I ran a line to my firwall to a T, then a line to my turbo:

nah I havent installed anything yet,
all my stuff is just parts sitting on my shelf.
but my plan was to go right at the block.

I have fittings to have the pressure senser on there also,
is that black thing on your setup the sensor? that things not that big.. hardly big enough to break a fitting.
although I guess with the oil line and fittings all pulling on the source it could be a bit of weight.

anyone ever have a problem with it breaking? Is that the only problem causing people to steer clear of doing it at the block?

thnx.

Get a sandwitch. That tee gets messy on the firewall and your patch hose will probably leak.

I use this and it works perfect. Enough outputs for everything you need.

Comes with plugs for those you don't use.

whats that big gold thing that the t's attach to? on the opposite side of the pressure sender.

I might do it at the firewall..
i'm getting a new motor soon, and will run NA for a while,
so I'll probly setup my oil lines then, and plug anything that'll be open.
looks like it'd be a pain to get under the intake manifold when the motor is in the car.

wow, i had an elec oil press gauge and mounted my sender with the same exact bracket i found at some hardware store in the same exact spot on the firewall. and that was like 2 years ago. i guess some DIY HT'ers think alike!

but yea, back to topic: in cases where you have many accessories and lines running off the tee from the block, the weight coupled with the vibration of the engine while running can cause the block to crack around the oil pressure sending hole.

I tee'd mine to the firewall just too make things easier to work with. I also have a adjustable oil pressure valve so it's just easier to adjust.

The fitting will brake off your block, it happens 90% of the time. Run a feed off your block first!

90%? id like to see that number backed up. i ran straight off the block for 9 months before i got rid of that setup, turbo kit and motor in a new car now and new ownser, still no problems. some people just get all the luck i guess.

ps, im not saying run it off the block, my next setup will be on the firewall im just saying 90% is a hard number to believe.

Believe what you will, when your block sees no oil and you spin a bearing, think of me.

i seriously doubt 90% is anything close to being accurate, i personally have only seen the stories on the net and never in person, but maybe me and all my friends are just lucky

properly installed w/o overtightening and just a feed line you will be fine, its when you start installing sending units etc that i would def go to the firewall

Adding senders and other weight is exactly what causes the problem. If you are using the wrong fitting that plays a part in this role as well. What I was saying in the means of 90% of them breaking off was meant twd 90% with the wrong fitting and extra weight break off. I have seen it in person dozens of times at the track and on local cars. Most everyone I have meet has learned and does not run such setups.

The block cracking is just another honda myth. Kinda like you can only use honda bearings in your motor.

Of course, you want to hang as little as possible off the back of the block, but I challenge anyone, with any type of connection that broke to post pictures of it, and I'd bet that in more cases than not you'll find just the dumbest things being done for this to happen, wether it's the wrong 1/8 thread going into the block, or a completely stupid amount of unneccesary things hanging off of it.

I've been meaning to do a stress test on a correct thread sized fitting correctly putting it into the block and hanging different weights on it to get an idea of how much it would take. Of course it would be hard to simulate the vibration of the motor, but it would give everyone an accurate idea of how much weight could be held, and we wouldn't have to listen to claims of 90% of all fittings on a block cracking.

Now all I need is a crapped block to test it on.

no if you run the T's off your block the T's and the fittings may break.... not 90% of the time, but often... do not run them there.. one T has lasted me a long time without breaking, but when you have 2 or more it'll break for sure... just give it a short time...
