We show you the important aspects of oil clearances and connecting rod end-play which is most often overlooked during the measuring and up to the build phase.
We also mention things like "Piston Guided Rods" as well as hints of what seasoned builders or shops do like 4Piston some good pointers that would lead to a higher efficiency and thus leading to excellent power making capability of a built engine. It could be stock or well souped up, efficiency will always lead to greater power capabilities and so this video adds a bit of informative ammo for you guys

Good videos, not full of personal revelations, just engineering.

Thanks brother

[@sagittnet2158]

Never had a rod spun on all my frankeinstein engines (H23vtec, G23vtec) before. I've experienced 2 engine blew up but never a rod bearing spin and hoping l dont have too. But you send out a good point and good information, specially for thosw slots on forged rods, thank you very much.

This video is so appropriate; I just took apart a B20 bottom with a spun bearing. Machine shop said all journals (Rod and main) must be cut. I am thinking about getting a replacement B18C Type R crankshaft and rods.

[@Clerique]

I have the option of B18CR crank and Manley rods or LS crank and Manley rods for same price. What would you suggest?

[@jamesnewton8164]

I want to do my h22a again im curious on what wpc treating will help me most? Id love to have you guys port my head and even assemble my frm sleeved block. Im running all motor but eventually nitrous

[@SRDmotorsports]

Wpc I believe ur rods and crank could benefit from by strength improvement and also friction resistance, as I see it done mostly on gears etc but on engine internals not many care to show their secret 😂

[@dawsonmacie6984]

Do you think at the dealership when rebuilding motors they just use plastiguage or you think they have dial bore gauge, micrometer etc..? I want to build my motor and not spend so much extra on measuring tools. Besides dial bore guage and micrometer what else should a amateur engine builder have? Whats the tool that sits on top of the block and checks if the piston comes out of the bore?

[@SRDmotorsports]

most likely dealership has the tools but also back then they had access to “all” the color coded bearings to match the block and crank etc etc whereas now the “std” we get is technically the “green” on the coded bearings hence plastiguage helps atleast to double check That took on top is I believe “deck height” measuring stand or deck bridge etc

[@sonotover]

If I have a slight bottom end rattle, almost like detonation sound under load, and a low oil pressure flicker and increased bottom end noise, is this likely due to main bearings or would it be smart to replace the rod bearings also?

[@SRDmotorsports]

Yeah safer to do both

[@dawsonmacie6984]

Does gsr rods have those holes to squirt oil on the skirts? Or the actual oil squirters are better?

[@SRDmotorsports]

Both seem to work the same… but even with oil jets on the GSR ? The GSR rods still has the ridges on the side as I mentioned on the video Makes us see that Honda made “sure”

[@Shortshifter04]

Interesting. All the non vtec rods I've ever seen are not slotted that's for sure... Do you think shot peening LS rods would then give them "equal strength" to a slotted rod? I understand the non slots still "restrict" flow but I'd think the cooling effect it provides is what makes them stronger/more reliable

[@SRDmotorsports]

The slot is to cool the piston the non vtec ones don’t have it because they have the rod bearing hole as I showed on the video that’s their “oil jet” Shot peening is a good way to reinforce or restore the rods strength sadly nowadays less and less machineshops are equipped to do this but a few that does, we def need to share support to them so it will continue further

[@ferdinandbenjaminco9113]

He'll yeah good inf the nobody talked a also can u give me a tip to go better on a b18a engine (internalParts)

[@SRDmotorsports]

Oh nice a b18a but vtec ? Or stay non vtec… IMO arp rod bolts on stock rods is hard to go wrong with especially with a lighter piston at 81mm than most in a b20 that has 84mm just looking after the bearing clearances and oilpump (both plastiguage vid and oilpump vid I have here) should take you a long way

[@Digitaltiger123]

What about drilling holes on the rod bearings and keep the p30 bearings which are better for vtec builds?

[@SRDmotorsports]

they’re not better just cuz it’s from a vtec base engine ACL b20 rod bearings is as good as ACL b16 and same with Daido But yeah free to mod to make the incorrect bearing work for the application

[@Digitaltiger123]

[@HarleySLA]

If I wanted to go from running 5w30 to 0w20 on a d16, what steps should I take to have proper clearances and have good oil pressure. I know I can blueprint the oil pump but surely that's not sufficient. Is this just a pipe dream or something I can viably achieve? Is it something that I should even try. I'm just curious about it

[@SRDmotorsports]

I think 5w30 is quite good in my book… While 0w20 and newer oils may seem enticing let’s not forget most are “roller” rockers now so would our rocker arm pads and cam lobes will like it? Either way I think what works as far as clearances on 5w30 might be close enough for 0w20 I mean it’s not as big a diff unlike 5w30 vs 20w50. And even then people still try to run factory clearances and run that thick oil 🤣

[@HarleySLA]

@@SRDmotorsports I'm speaking from a purely efficiency standpoint. Whereas a lot of people are going for power building, this is an economy build for me. I was the maximum mpg possible, that's my goal for this particular engine. I figured the lighter oil could help, but have been afraid to dive in, I'm a line technician and I've rebuilt a few engines but I'm honestly a bit scared to dip my toes. So I'm here trying to research and gain insight so I can have a 50+ mpg car. It does pretty well as it stands, my record being 45.6 mpg on a tank with a mix of city and mostly highway miles. Sorry for the long posts, I'm super long winded, don't even get me started talking about tools haha. Great channel man, I enjoy your content, definitely subscribed and I hope you reach a huge audience with your knowledge.

[@SRDmotorsports]

@@HarleySLA oh man I agree not about tools… it seems I can never get all the tools that I need and there are more that I need hahaha wtf! now that u mention that? If it isn’t cammed and all? Then I see no downside in trying it My worry was on bigger cams and stiffer springs we still are not a roller rocker system… but other than that, I’ve rebuild a bunch of L15 motors from the Jazz/Fit model and the clearances (bearings) don’t seem to be that much different from the Dseries range… they got real narrow bearings doe especially rod bearings… Now when u think about it “oil exit” was definitely taken into account… Man thank you for checking the channel out, definitely appriciate that but also comments like this makes it even more fun! Plus we know some read this comments and enjoy the info too we know we know 🤣

[@HarleySLA]

@@SRDmotorsports Thank you very much for your time and replies. I agree 100%, there's never enough tools haha. I'll try it out and see how it does and if the oil pressure changes dramatically versus mpg, maybe a highway test. I'm thinking of building a K eventually for a swap into a 93 Integra. I have the engine, I just want to research and figure out what I want to do as far as power and drivability because it'll be a daily vehicle so I can't go too crazy. Thanks again and mad props for everything you do! Cheers from the USA

[@SRDmotorsports]

@@HarleySLA oh nice u got a K hanging out somewhere! def a good way to make crazy ideas hahaha! Thank you for this man! And on the efficiency of things I tend to talk about it cuz most of the time on performance related stuff it sometimes take a back seat when in reality it still sits in the “front seat” of things lol if it’s a stock cam and springs? I’d def look into it I mean the oem “mains” already look good in my book to handle it… the rod side clearances may aid some if u know what I mean 😎 ….il say what u said now… don’t get me started on efficiency talks especially on things like 60% of the piston ring friction comes from the oil control rings… hmmmm ok I should stop As we still actually do race locally hahahaha

So if i wanted to use Speedfactory H beam rods for a turbo D16y8, would it be worth making those oil relief cuts on the side rods because they don't have an oiling port?

Can a b20 block handle oil squirter's?(with proper mod)have you tried?

The b20 block has no provisions for oil squirted on the oil passage so machining it will be senseless and more expensive than just going with a b18c

[@SRDmotorsports]

@@sabz_bhp look at the rod bearings = if no hole then it’s a b16 rod bearing Thrust washer if it’s installed with grooved side “in” facing aluminum block then zero to no or low oil pressure lastly Check oil pump… the oil pump cover should be “hell” to loosen if oem but if u can easily loosen it? It was propably opened and checked but not closed properly = low oil pressure Lastly oil pick up tube A lot of times the paper gasket is effed up and when tightend together it’s not air tight so the oil pump sucks air too and that’s Starbucks level froth oil to the bearings lol
