Eagle rods have no bearing oil hole? wtf?

[Rennat]

So i've been looking at my eagles for the past few days... and i cant help but notice that they have NO hole drilled in them for oil to get to the bearing... am i just on crack or what? somebody please tell me im not insane and that my motor will not get rod knock in 40 seconds...

deffect?

is thier a hole at the top of the connecting rod?

I think they are made that way.

 

[Zumtizzle]

The weak point of this rod is the stock bolt, and then the drilled oil hole/squirter in the shoulder... (And it's loss of oil pressure right where you need it the most... )

The stock rods are pretty good for engines under 500hp, and that will see stock RPM limits in my view.

Some have made more than 500hp, but others have seen failures at less, but not much less.

My rods are now from Pauter, and have no such holes.. also my rods are custom sized for 2" bearings from a 327SBC. This is a smaller rod journal than the stock 7M. The rods in the stroker motor are also 6" long, slightly more than the stock 7M rods too.

I'll let adjuster chime in.

I thought the hole was supposed to be on the other side? It is on stock rods, anyway.

Doesnt the oil go the other way? Out the crankshaft and into the rod bearing? The bearing will get oil but there is no oiling hole to the piston pin.

Edit: the hole in the stock ones sprays oil to the bottom of the piston.

Edit #2: I was wrong again, answers are here

so.... its 100% ok not to have any holes in the rod bearing area? theres 1 on each side of the piston pin bushing.... but none in the rod area... but, your all saying its ok? i'll go take some pics of the rods for you all to look at.

your oil is fed to the big end of the rods via the crankshaft. There is plenty of oil splashing around to keep everything lubed when the engine is running. That is how the rods are designed for eagle and others and that hole is actually a weak point on the stock rods.

but if you want the hole send them to me and i will drill you a hole :biglaugh:

lmao - quake is right - oil is fed via crankshaft

 

[Rennat]

i would rather ask a dumb question now then look dumb once the motor is together.

Are there going into a GTE block?

 

[Rennat]

Yes IJ they are going into a turbo block. a good 90 block with the extra ribbing and all of that good stuff 90+ blocks have

 

[IJ.]

Cool at least the bores will get oiled by the block squirters.

I was a bit worried by this using the Pauters as they don't have the Oil holes either, I made sure my idle pressure was enough to open the squirters around idle.

Pauter now offer notches in the big end flanks to preform this function.

 

[Supracentral]

Just about every aftermarket rod that I have worked with for the 2J or 7M lacks them. I've never had a problem.

When did Pauter start notching them? That's new to me.

I've always just installed new block sprayers from Toyota during the build.

 

[IJ.]

Mike: Brian started offereing as an option a couple of years back, from memory he's using an EDM to do the notches.

7M notch will be at an angle to spray the thrust side of the bore like the stock holes.

 

[jdub]

Ordered my Pauters with that groove

 

[Tire Shredder]

since we're on the subject of lubricating the pin/bore.... do you think an NA would see problems with lack of lubrication on said items with a crank scraper installed, since there would be no oil squirters to spray directly?
