resleeved.. pistons rods.. valvetrain.. all that good stuff blah blah.. i just got the car running.. first of all.. im using a spoon ecu, no vtec engagement for some reason.. i'm hoping its wiring but i'm not flashing any codes, and it only revs till 5500.. not bad for breaking it in.. but wtf.. i've heard a lot of different ways to break a motor in.. 10lbs of boost first 3 runs, 20lbs next 3 runs.. blah blah.. or don't shift over 3k for 1000 miles.. well unfort. i broke a connecting rod bearing today.. so after i put it back together, i'd like to know a few more opinions of how to break a motor in.. thx

mine's finally running too and i'm breaking it in as well. it's kinda hard for me though because i don't have an exhaust yet, so i have to drive it around the hood. i've already taken it up to ~6K though. just drive it around like normal and it'll break in soon. don't boost while breaking in though.

you BROKE a rod bearing? do you know why it broke?

 

dunno why it broke.. i'm replacing it today.. the cars making no power either and cuts out at like 5500 rpm.. its gotta be a wiring problem..

 

Who the hell told you to do 10 and 20lb boosted runs??!? Broke a rod bearing? ironic.

There are a few different angles people take to break in a block, but i've never heard of that one!!

You need to fix your vtec issue before you go breaking in the motor any more! ( or breaking the motor)

 

vtec dosn't engage till 5-6k.. if i'm not revving past that.. why would it matter.. and btw.. i'm friends with a few pro import drivers and thats how they break they're motors in..this car isn't turbo'd yet.. i was just saying methods i've heard.. anwyas.. cylinder 1 and 3's bearings are kinda shot.. so i'm replacing those.. very little damage to the bottom of the sleep.. which i don't think the piston even reaches.. i'm hoping it was just oil pump.. and if it wasn't it was prolly a bad sleeving job

 

yea dude, who the **** told you to do 3 10psi runs followed by 20psi runs? Anyways, a good way to break your motor in is to run it n/a after it is built for about 500-1000miles, then install your turbo. If you dont wanna run n/a, baby it for 500-1000 miles without boosting, dont go past 3-3500 rpm's for this break in period. Also, you should use non synthetic oil when breaking the motor in i believe. Change your oil after your break in period and when you are running turbo go back to synthetic or the oil of your preference.

actually your supposed to changed the oil after the first 50-100 miles i think.. btw that whole 10lbs 20lbs thing works.. we did it on my brothers car..

 

ok, nevermind my advice. have fun boosting 20psi on the break in.

 

i didn't put the turbo on my car, i'm breaking it in NA.. i said i've done that before on full out track cars.. and it works fine

da flames...
cant you people listen! jk..
i just need more post...

 

you are lucky someone locked your last thread about the h23/h22 head. use the ******* search button and stop being a post *****.

 

Yeah you go ahead and do that...( )

Just don't cry at us when the motor's spewing out oil through the exhaust!

 

yea no ****. who needs to let piston rings set anways!!!! Some people just never know when to admit they are wrong.

 

 

..i'm telling you, i've done it.. on track car's.. that have ran entire season's on the same motor with the same internals.. i asked for methods to break a motor in, not what you guys think are the wrong methods, if your not going to cotribute anything that helps me out.. don't contribute.. i guess thats hard to do for some ppl.. boss hogg, thanks for your help, the rest of you.. stfu

 

riiiiight. we've already contributed our .02 and you told us we were wrong, if you know everything then why are you asking us how to break an engine in? go ahead and boost 20psi on your freshly rebuilt engine

 

it dosn't have a ******* turbo on it.. how many times do you want me to say that

 

Gudeh23a: after breaking in my built up engine and putting in turbo, should i go to sythetic oil at that point? Or should i still run non-synthetic for the turbo break-in period and then go to sythetic? Dont even have the engine yet (h23a1 blocks are hard to come by) but i'm trying to get as much info as possible

I was replying to that post, im done wasting my time with you. someone lock this thread.

 

i have to agree with Gude 110% i have always heard that too. street car, race car, factory rebuild it doesnt make a **** its all the same break in (or should be)
