Got my MBC today

are those little slices on top of the line i see?  i'd be interested in this. any more info?

Those were my marking points for my home made cam squirter.  Small .005 holes to start with getting bigger as they move further away.  Originally tried the same size hole for all of them but the oil pressure would not push the oil to the end of the tube.

So is it basically just a metal line bent to squirt into the holes between lifters to hit the cam or did i not inspect enough.  Oh and those are flat tappet lifters.  Roller lifters require creating a device to prevent the lifters from rotating in the lifter valley if I remember correctly.  I know Jud's setup had a coat hanging and some springs.  I forget what else was required.

I forget why we decided not to go with the roller lifter but there was a good reason at the time :icon_rolleyes:.

The metal line is a BRAKE line flared on one end where we taped into an open oil passage.  I just used a tube bender and it squirts onto the cam lobes.   It was cut to length and caped off.  When we primed the engine it worked awesome.  Once it is done breaking in and I switch to Amsoil it should do even better.

Does it do as I described or in a different method?  We may have to do something similar especially knowing the issues with the what 9 and 10 lobes that tend to go bad on the engines.  I would also assume you went bigger the farther back it goes because the oiling becomes worse and worse.

How big is the largest hole do you remember?

Its been a few years (and trips to Iraq) since I built the motor.  I remember we used a .005 (smallest in the drill bit set and did 1/3, then used the next size for the next 1/3, the the next size up for the final 1/3.  The oil flowed pretty well while being primed.

It squirts the oil onto the cam lobes.

Another option is to get your cam cyro treated (read hardnened) or coated with a coating to further its wear.  here are some links :icon_cool:.

Got another question, I still haven't put it in yet, I was actually gona do it this weekend probably after I pick up a boost gauge and air/fuel gauge. Is there going to be a problem with disconnecting the factory harness on the stock controller or does that wiring harness on there only send info to my gauge clusters boost gauge?

[killinprixs]

the crappy boost guage gets its signal from the map sensor.

so it not being hooked up won't hurt anything? Where does the gauge cluster get it's reading from? Where do I tap off of for my aftermarket boost gauge

[killinprixs]

the guage cluster gets its reading from the map sensor.   Most guys T off the map sensor for aftermarket boost gauge.
