I've heard that alot of poeple are telling how h22a's are spinning rod bearings like crazy.. well i know why.... it's pretty easy actually..

I learned this because of my h22a1 (JDM motor) it seems that 92-95 closed deck motors had connection rod bearings which had oil holes in them for oil passages... after attempting to rebuild my block (reliabitlity's worth) i noticed that the new connecting rod bearings supplied by "OEM HONDA" do not further include the oil holes in them... i had the dealer ship called the headquarters and seems that all bearings are now being replaced by these.. which was i beleive done in 96+ models... now i'm not sure if those motors do have connecting rod holes in the crank.. but defenely mine do in the "A1" series...

it would be interesting to see if somebody had their a4's appart to see if the connecting rod bearings have that oil hole.. if not it's pretty evident to know why they spin the rod bearings because of lack of oil on a quick turning surface...

"defenetly worth the research"

i know the new ones will be drilled for my application... anything less would be an insult...

can somebody with an a4 block verify this...

i beleive the solution to this was that honda did find a problem with the h22a motors taking oil consumption problems.. and this was part of the problem... i'm not totally sure or not .. but could be ????

 

the 96 is A1 as well so the same as yours.

And all VTECs from 93-01 burn oil, so I dunno about that theory...

 

when i took apart my A4, the bearings did not hae holes in them, not did the connecting rod have an oil feed hole

your theory is bogus, sorry

70k+ miles on mine, it only had 20k when i bought it, which means 50k miles at least of hard driveing, full throttle shifting, bouncin off the rev limiter, and aboslutely doggin the hell out of it at all times, not to mention the 8 or 9 months i had a 75 shot on it before it eventually burnt a valve

 

A lot of people tell me that a honda isnt capable of producing over 400hp either, but that does not make that theory true. It's cool you are trying to learn a little more about your engine, but your theory is incorrect. I need to give you reasons and i will do so as soon as i find the thread on this, because i honestly dont feel like typing all this info out.

 

but why would honda remove the oil holes in a4 blocks.. we all know more oil flow is better for rod bearings in either condition.. no oil holes would depend on the oil that the bearing retains and what happens when that one gets abused and looses it`s properties... it could not help.. rather than an oil holes that supplies new oil on demand would better for reliability can`t hurt... that`s for sure.. `m just looking at stuff i`ve noticed that`s all.. another thing i`ve noticed is the front seal and rear seal on the h22a .. seesm my crankshaft had slight knotches like the bearing was either too tight on it or rubbed from idling to much.. ether case i had sleeves put on .. so it would ensure a proper seal next time around... just curious if you guys noticed that as well....
