Any one interested in the oiling mods I did?
First off GJ, I love the way your car launches.
Secondly, thanks for posting this as many people would not spend the time to do this especially with pictures, I take my hat off to you.
I understand and agree with the oiling mods except one of them which needs clarification for me when using hydraulic lifters.
Now for you guys running hydraulics this is the best thing for you to do. Instead of blocking the oil from the main bearing saddle to the left side galley, block the oil to the #1 main saddle coming from the right lifter galley. You'll then need to drill tap and fabricate a line from the right galley to the left galley such as this. Use either 3/8 hard line or -6 braided line.
I am having a hard time understanding the cross tube aspect of this modification, especially when
blocking off the feed to the #1 main bearing.
Heres why;
· The tube from the right oil galley is feeding the left oil galley and that oil must make 5 turns to get to the #1 main bearing
· Every turn reduces flow
I just cant see how this is beneficial, 5 turns (when blocking #1 main from right side) to 1 turn (if not blocking #1 main in stock configuration) and not using the cross tube.
From Moper's post;
Also, the reason for the crossover tube as I understand it is not to help oil the tappets on the left side but rather to help the #4 main. #5 is fed from the main passage itself but #4 starves at high rpm and that cross over helps the oil turn and go down to the main bearing. I've done that mod on an engine that had issues with the #4 main showing signs of starvation and it solved it.
Now, if it is true that this cross tube helps prevent starving of #4 main bearing help me understand this as well. Here is my take on this.
· #1 main is NOT blocked off
· The cross tube is fed by the left oil galley
· When the tube feeds the right oil galley it is travelling vertically smashing through the oil in the right galley traveling horizontally
· This smashing of the two different travel paths are causing turbulence
Can I get reasoning being this cross tube mod. Am I missing something here?
I am not questioning your skills or knowledge, just trying to understand the why behind it. I will be doing these mods but am holding off on this cross tube part until further clarification.
A couple of more questions.
· When restricting the oil to the cam bearings we do #1, and #3, what about #5?
· For the cross tube, is it possible to use straight fittings and just bend the line to eliminate two of the corners for better flow since it can be smooth, if there is enough room, just a thought/suggestion.
I appreciate your efforts and eagerly wait for your reply.
Thanks
