question? would you wanta restrict oil to a factory hydrolic roller lifters???
. No only solid lifters.
Back earlier in the thread guitar Jones showed the method to use if you were using hydraulic lifters. You then would use the crossover line method. You could still restrict oil to the cam bearings. And you could still could feed the rockers directly from the galley instead of # 2&4 cam bearings. Therefore 2&4 could be restricted as well to help oil the crank better.
Is there anyone who has all the missing photos from this thread? Cley
Photos seem to be there for me. The photos do not start till quite a few pages in. I just looked at the thread again and I get pics.
What post number are you talking about?
28, 73, 107, 124, 126. it's the meat and potatos of what I hoped to learn and the photos don't show up for me. Maybe it's just the computer I'm on. Does everyone else see them? Cley
. All there but 73 & 107 had to click on the jpg link. So yes all the pictures are showing up for me. And I'm using a smartphone on Android.
all the pic's are showing up for me.
I'll try my phone. Cley
Question, if the right lifter galley is tubed & #1 main is blocked off, how does #1 main get oil? I had a used 414 engine that had been tubed & running solid roller lifters. It didn't have a crossover tube in it.
. If the passenger side is tubed you do not use a cross over tube. The 1 main is oiled normally and the passage is blocked on the drivers side.
Sounds good I saw the tube kits offered on Fleabay !
So tube option is a good idea for high reving flat tappet applications as well ?? If so I will purchase one because block work will begin soon with my build.
. Just don't use it with hydraulic lifters weather flat or roller.
I’m giving some of these mods a shot. First attempts below. Still have to mod pump and remove rear plug for oil filter hole drilling. Also need to double check on the soft plug in rear cap area as I may have accidentally drilled it out. Not sure.
Here is a video showing the plug that is below the main cap. Also the Chinese oil pump production QC failures unless I’m missing something and someone can explain it better.
. . First question is did you remove the plug that you show at the first of the video that is up under the main cap. If not you need to because there is a bottleneck under there. It needs to be drilled out. Now on the pressure relief valve in the Chinese oil pump that is not a problem with that hole being exposed because that is just part of the valve that bleeds the oil pressure back it is not what actually stops the oil flow at low pressure. You will find when you pull that out that the valve has other orifices on it and at the head inside where the spring sets is solid. I believe you need to pull that valve anyway to clean up the passage behind it. I think that you're over thinking that relief valve is what I'm trying to tell you and that your new Chinese pump is just fine.. Also if you're going to use the crossover to feed the number one main you didn't need to drill out the passage coming down from the passenger side to the main. That being said if you do use the crossover you do not need to drill that passage out bigger anyway because it is only one rod being fed from that journal.
Thanks for that info. I will pull one of the relief valves and check it out. Already bought a new stock volume melling pump but I’ll be able to use that on a third engine I’m building if these 2 are actually good. I don’t plan to use a crossover unless it os “required”. Stock system would have most likely worked for my application. Blower/turbo and 62-6500 max rpms. My thought is opening up the feeds leading to the mains, working over the pump, and getting as much oil to the gallery from pump would be added insurance. I may be wrong.
Enjoyed your two videos. Especially the little ball of energy that was running around there.
Which galley needs to be plugged coming from #1, Why? And do I really need to have the crossover if the galley to mains are opened up on all journals and full flow is capable to entire block? How do I mod the pickup/plate from bottom of pump cover to suck properly? Questions in video below.
Nice video I see you have your star in it. Look at this thread I just created and see if it helps you out. Are you going with a solid or a hydraulic cam? Are you going with a rear sump pan? If so you know you cannot run a pickup off the bottom of the pump. You need a rear sump pan to do that. Still working on getting my pictures to upload on my thread I started. My take on the oiling system crossover tube for the small block
Hydraulic. Car pan mid sump. So, I'm kinda limited then on pickup size to the factory 5/8 ok pipe. That thing is skinny on the inside. .625 ID with a min. of .440 ID. So after drilling everything to 1/2" feeds It seems I should have at least a 5/8 id pickup. What are the options for center sump guys? Got some pipe plugs and set screws from Lowes. Picked up tap n die set from Autozone. Only pipe taps I could find were 1/8 and 1/4' NPT from O'reileys. Headed to your link now.
As far as the photos go if a mod could move them to the forum server that would be great. It's been long past where I can edit the posts and add the photos myself. They are hosted on picturetrail.com and that account may be going away soon and so will the photos so if anyone could help with that it would be appreciated. Thanks.
