I was reading their site, and noticed that they tee'd off the block for the oil supply line to the head. On another ls/vtec site it said "DO not T off the block" http://www.geocities.com/thelsvtec/sshowto.html



What gives?

That's where I T'd off for my oil line so if any one has a good reason why not to please post.

From the Endyn site:

"I fully realize that this may seem to be a simple enough job for most import enthusiasts, there are a few things to consider in the plumbing process.

I'd like to point out that we've seen many engines over the past few years with broken oil pressure fittings and internal damage, that we should take a hard look at the situation.

The accepted conventional way of plumbing these gauges has been to add a "T" fitting to the side of the block, with the tap at the stock oil pressure sensor's location on the block.

It all looks easy enough, but consider the weight of the brass "T" blocks that are used. When this mass is hung even a short distance from the block, the famous 4 cylinder's vibration can quickly work harden the brass resulting in a catastrophe if the driver's not right on top of things.



Here's a picture of one of the "conventional" methods for plumbing the oil pressure source for gauges as well as for feeding "other" oil hungry accessories.

Note the distance between the block and the end of the assembly. Perhaps, in this view, you can see why it's a dangerous combination.

This next illustration shows the configuration that we prefer to use at Endyn.



Please forgive my "art work", but it should be readily apparent this method removes almost all the stress on the block at the point of connection. The best place to mount the brass "T" block and the respective taps is on the firewall. The connection between the block and the "T" can be with either nylon tubing or braided steel. It's important to make sure that the connecting line is not tight. Putting a lot of slack, or a loop for strain relief will insure that the engine can vibrate and "rock 'n roll" all it desires without causing any problems."

Hmm, has anyone suffered from this first hand?
My buddy Ryan has been running his hatch like this for a long time now and nothing has happened?... Well I figure that if the block is "rocking and rolling" like Endyn said, wouldn't the line and the head move aswell?...

I know of people who have had their tees break on them. its not pretty.

It is a concern... don't over look it. However, we've never seen this happen before. The quality of the Tee used plays a role.

Notice the Tee we use doesn't have an adapter fitting into the block.

Here's a pic:




Use the right parts.

This is how it looks on the other site. I am not trying to start poo poo, i just want to build it right the first time. Which is the best way? When it comes to proper building of a motor, i dont mind spending a few extra dollars if necessary

Ok this is what we did so I guess its not as bad as the other one.

Ok, thanks for the input guys.

HaUTSaauce

thats what i have done and i have had no problems

. o 69 o .

how long have you been running your set-up? how many KM's?

We always use those Tee fittings.. On the local motors, i'd venture to guess that there is over a combined total of 30,000miles with those tee's, and no problems.

Again.. if you are paranoid, the better way is to put the tee on the firewall. Entirely up to you.

This mainly talks about brass fittings. What about steel fittings, I know of people using the steel T fitting, and nothing has happened.

I put my tee on the firewall. It's more of a piece-of-mind thing for me.
