Proper Engine Break In Procedure

[@maperformance]

Tell us your experience with breaking in new motors 🤘

[@welcometoreality3450]

why no mention if you should drive it hard early on or not?

[@jaredmayer3960]

After first start, 20 minutes at 2500 to get the cam ZDDP adhering to the lobes, then hit the road, 20 3rd gear pulls from 2000-5000 rpm and coast down to 2000 and do it again. After that drive normal, oil change after first fifty miles, then at 500 miles, then normal. Thing uses no oil, and when taken apart there was no black between the first and second rings. Straight forward and it never fails.

[@christophercasey8833]

20 minutes: at 2k Check vacuum. If in spec change the oil/filter. If not in spec inspect and run if assembled correctly. Bore scope the oil pan, strain the oil with a paint filter. Release fuel pressure at rail, pull fuel pump fuse, reprime, add fuse, start, run til thermostat opens at 2k rpm. Let the car idle from a stop so there is no lugging, then accelerate slowly in first gear until 2k rpm. Do easy pulls in first from 2k-5k, use engine braking. Do this until you feel the engine braking working harder (it might suck at first) Pulls (gentle) in 3rd from 2500-5k with engine breaking... feel free to drop the throttle quickly every time. Pulls in 5th from 2500-5k same as before Change the oil, check everything, reprime Drive normal for 250 miles, no redline, change oil to sythetic Dyno tune, red line, brap brap A little side note/something interesting... there are several engines that require the engine to sit at 4k rpm for 5 minutes to bleed the cooling system. How do you think these engines are broken in at the factory? 🤔🤔🤔🤔🤫🤫🤫🤫🤫🤫

[@3geclipsebuiltperformance883]

I would just baby it until u hit 500 and dont forget to change the oil as needed per miles driven

[@3geclipsebuiltperformance883]

That doesnt always work and is bad advice every build turns out differant i am not trying to argue but what works for some does not always work for someone else word to the wise i blew my first motor that was built that way in my 99 mustang gt

Followed this guide to a T two years ago when I first started up my tiny 1.6L VW motor w/ forged internals. It does not burn a drop and has an outstanding 260PSI across all four cylinders. Factory spec for new is 240 ;)

[@maperformance]

Woot woot!! Dude that's incredible to hear.

[@DrGamble28]

60k miles on a M42B18 rebuilt engine and I didn’t really do much of a break in. Covered cams in oil before I put the valve cover on, poured some down the timing chain, a little on the cylinder wall and it was fine. Drove around for 100 miles varying streets and highest speeds at 30-40, then 65, 70, 65, 75, 70, 80 mph. No burning oil, no issues after 60k miles

[@julianjennings4638]

One of the most complete and correct break in videos I've seen. Would like to see You do one on engine assembly. Prep. Cleaning. Assembly tips. Installation. Thank you again for your time and knowledge.

[@aidanhamilton9859]

I did my first oil change after my cam break in. Than put about 500 miles on my jeep just to be safe than started romping on it and playing with the tune. Been fine since. 2k miles later, still perfect.

[@ностромов]

It's always going to "be fine", pretty much no matter what we do. By the time gaskets, or something, start leaking - those engine components are long destroyed. It's not going to instantly show that we did everything wrong. :-$

[@jdoggybizzle]

We broke in a Mazda V6 KLZE with a mild build on it. We did the first 30 minutes of idle and heat soaking the engine, then did a 50 mile break in on conventional Shell Rotella which is a truck oil for semis with a high zinc content. Then we switched over to Mobil 1 full synthetic 5w-20 and ran that 500 miles. Everything was golden. This is an engine that now has 12000 miles on it and some of those miles were full tilt track days and flat out top speed runs and it's fine. No oil usage, no metal in the oil, just a good all-around engine. We're going to use this video to swap in a fully built KLZE with MAPerformance parts! We bought a Precision turbo from you guys and once we get it broke in we're adding the turbo stuff. Shooting for 700whp it's going to be a riot.

[@justinross2380]

Great video. Using this for my built N54 (first full motor build for me), currently at mile 300 of the 500 break-in interval. Stoked to get back on your dyno, nearly 5 years later, to see what it puts down!

[@maperformance]

Sounds great! Good luck!

How did it turn out I have a n55 I built and I’m tryna see what would be good for the bmw

[@brianbrazil9909]

I built a trailblazer motor with red valvoline wheel bearing grease. I thought i had a tube of assembly grease and didn't realize i did it until 6 months after finishing the engine. It runs great with now 35,000 on the motor. Guess it didn't hurt anything and boy did i luck out....

[@ethanbunch3274]

I'm about halfway through building my Ford 302 and this is another topic I've been itching to know more about since it's such a critical step in this process. Raising the compression to about 10:1 static and 9.1 to 1 dynamic. New one valve relief pistons made of forged aluminum and AFR 185 enforcer cylinder heads. Should get about 400 horsepower on the high side and I'm just stoked to get it running!

[@sbf432]

Personally i fire it up and beat on it never had a problem. Supermoto break in procedure! To each there own

[@patonbike]

subaru owner - I put an oil pressure sensor on both the front and rear oil gallery . You can crank the motor without plugs/fuel/spark until you actually see like 50psi of pressure. (Obviously do not run starter motor for too long in 1 shot, but without compression it is not a lot of resistance). Also, a trick for Subaru oil priming is to crank the motor WITHOUT an oil filter until you see a small stream of oil coming out of the oil filter port (It should not be long, like 10-20 seconds). THEN add a pre-filled oil filter and crank again until you get oil pressure. This will get it primed and pumping more quickly.

[@hjer731]

This is all too much dude

[@patonbike]

[@Creeks_and_critters]

For my fully built EJ25 I did 20 minutes - oil change. 50 miles under 30% no boost - oil change. 150 at 50-70% no boost oil change. Now I’m on normal oil at 200 miles and running 8-10 psi 50-70% throttle. 250 miles I’m sending it.

[@thetotlpkg]

Did it blow up or still going with that psi?

[@thetotlpkg]

@@Creeks_and_critters makes me feel better. Just rebuilt mine and I am 100% sure it put it together correctly but still have low oil pressure. I guess I will break it in and see what happens.

[@johnryan8985]

I saw a ring company say you want the break in oil during your 20 min anxiety fest. Something about the higher zinc, and if you get blowby you are doing more damage not using the thin specifically designed oil. After 25k of upgrades I'm good dumping $50 of oil.

Great video and tips on running in a rebuild engine. After the 500 miles run in does the engine head need to be tightened again especially allow heads like Honda?

Fuck ya bud! I bet she’ll rip!

[@mikecroslin3743]

Should you change the oil filter along with the oil on all these initial oil changes

[@TEQ-Garage]

Correct me if I’m wrong lmao. But I’m pretty sure running normal oil to brake in the cam doesn’t heat treat it as well at all because there’s not much zink in it. Therefore it would increase the speed pitting occurs because the camshaft is soft.

[@whitejodeci8926]

I did 1200 miles on my new engine, not going over 4k rpms. It felt fine but for some reason it feels like everything has settled in more after I did a few redline pulls

Map performance is sick i evo 8 swapped my 3g thanks to them

[@maperformance]

Thanks John!!

[@dham99]

I have asked around and its funny how varying the advice is to breaking in a newly built engine. This one seems very logical...let it warm up, inspect for leaks, use a break-in oil to put it under real world load for 50'ish miles, drain, run new break-in for roughly 500 miles, drain and put in your synthetic oil of choice. Others have had zero issues running a warmup cycle for 20min on conventional oil, dropping in their preferred oil and just sending it without any issues. But why take the chance i guess? I have a 2.0l ecoboost out of my 2016 Focus ST that was big turbo, bent a rod at about 430whp. its rebuilt with all forged internals and is ready to fire up this week. I think Ill take the extra time and cost to do it like its laid out in this video. I'd rather not have to yank the engine out again just because i overlooked debris in my oil cooler or something

[@critterpower]

I messed up my break in process on a datsun L20b rebuild by using synthetic oil, it glazed the cylinder walls and now I have to rehone and re-ring the pistons due to excessive blowby.

[@EvatronX]

[@kamijoon4788]

Great video!!! I sure learned a lot. Now a concerning question: Some of the engine remanufacturers only recommend that we use conventional for entire first 1500 miles of break-in period. I like to know why do you suppose that is? And what's your take on that. Thank you!🙂

[@chasevans7171]

Just got my 347 stroker ford v8 (in a1960 british ford zodiac kustom hot rod) build through its cam break in, oil change and first 200 miles. I put comp cams break in oil additive in with the first sump of cheap mineral oil to try and give the new cam its best chances. Then after 30 mins at 2,000 to 2,500 rpm to splash lube the cam properly, drained and refilled with 10/30 comp break in oil. I don't normally worry too much if its a customers engine at work I've had in bits but on my own £2,000+ investment it just makes me feel uneasy and hypersensitive to any noises. I think I more enjoy builds like my drift car where its just a scrapyard engine transplant that even if it threw a rod out I can replace the whole engine for £300. Built the drift car and immediately dynod it and then took to the track without any worries. (saab b204 rear wheel drive spaceframed Ford mondeo eurocar. 840 kilos wet. 296 hp with slightly bigger turbo and a remap. Completely stock engine.)

[@WhatIs205]

Question, is ok for my motor to say stft 3, -6, 6, -8, 5? My ltft is saying the same thing, random and not stable. I've heard that it's supposed to vary but it's it by that much?

[@maperformance]

Yeah that definitely is a little too much variation. It's normal for those to move around but not usually that much.

[@WhatIs205]

@@maperformance I tried everything, for background I bored it from 86mm bor to 86.5, everyone was telling me that it's ok it's just .5mm over. I had to take apart my motor again and there was so much carbon that the valves were imprinting into the carbon on the piston. Do you think that it could need tuned? I replaced fuel injectors, maf, ECU, wiring, even wasted time making a vacuum test with a bolt and rubber hose. I can't find anything to save my life.

[@SupramanTRD]

A lot of good pointers here. Very relevant for me as i'm starting my first fully built 4g63 in a few days. The only conflicting info I hear everywhere is the intervals of the initial oil changes. Many are saying it's not necessary to change the oil after the first 20 minutes, and that it's good for the first 100 miles. Where you would then switch to your oil of choice. It's the first hour or so of driving where the crosshatching files the rings (metal shavings) and seats them. Correct me if i'm wrong, but it seems that all the contamination is going to happen over that first drive, not upon startup? Wouldn't it make sense to use break in oil up until 100 miles, then do an oil and filter change until the car hits 500 miles, where it would be done again?

[@yeetplays3421]

I just built my firs engine, b20vtec and as of this coming Saturday I will be doing my first start up. I’m extremely nervous that something could go wrong but I am hoping for the best. 🤞🏼hope it turns out good for me after investing a lot of money, time and scars into this built🙏🏼🙏🏼🙏🏼🤞🏼🤞🏼..

[@blackhorsegaming393]

[@donr62]

Cheap oils will still have friction modifiers and detergents in it. Stick with running in oil which doesn’t have those additives but does have high zinc.

[@allredred6646]

Great video

[@FinishLineFactory]

When you say 20 min of break-in, do you mean literally rev the engine between 2k-3k with no load for 20 min? Or take it around the block for 20 min varying between 2k and 3k?

[@maperformance]

Correct, no load for that first step.

Ik this video is a year old but I have a question about my build so its a fully built engine with a stage 2 turbo cam and will have a turbo on it since it is a NA car. Would I need a base tune before starting it up and breaking it in? What is the best approach in my situation?

[@mvnnyss3774]

Base tune with the motor alone first is best because you don’t want any metal going into the turbo maybe put it on after the 500 mile mark

[@mayowaodus6310]

At 500 miles when covering this. Do you need to also vary the engine Rpm or you can do a wide throttle opening

[@maperformance]

Typically at 500 miles you should still be city driving (low-mid rpm range). Usually don't want to go WOT until about 1000 miles. It all depends on the motor and tune though. Talking with your tuner about your specific setup is the safest route.

[@BonBon-il4wx]

So If I already had stage 2+ tune with e85 with FBO should I keep the tune during thr first 500 miles break in and tune it later?

[@richardchileshe9910]

Hi. Can i please ask a question and get your opinion? I bought a brand new CF MOTO 450RS motorcycle and from new, gear changes were rough and it had vibrations. After the first service, the bike felt a lot worse, and engine was over heating sporadically. At 1400klm I realised when the dealer said that it was normal and I had taken the bike back 6 times, back to the dealer, I investigated the problem and found the dealer was filling the oil to below the empty level. When I toped up the oil, it took 750ml to get it to the full line. That's 1/3rd oil missing since new. In the cf moto user manual it states that the oil should only be filled to below the low line, but in doesn't say if this when the bike is on the side stand or upright on a service stand. Turns out they were filling it up on the service stand in the upright, and those instructions were for the bike being on the side stand. So dealer was filling my bike and some others short of oil. Engine now sounds rough compared to new bike and I am hearing a slight ratting sound. Can you please tell me, during this crucial run in period, what is the potential damage to the engine and gear box? I think during the crucial 1000klm run in, period not having enough oil to meet even the bottom line of the low😊 indicator mark would have caused damage, but dealer said no, it's o.k..

[@08corollaxrsswap88]

First step dont put the oil pressure sensor in ... done now your good to start it

What happens if you have changed the injector size and cams and bored it large. Should I still start it before I take it to the tuner

[@danielpugliese7003]

No when the change the injector size it will run extremely rich because the computer still thinks ur running the smaller injector so the same size pulse sends more fuel than it thinks

[@maperformance]

Typically Tune shops can send you a base tune for you to drive around on. I recommend finding a tuner that can get you a decent base tune, that way you can put miles on everything.

@@maperformance i have the base, i can start it and pull in and out of the trailer, but i cant drive on teh streets, there is nothing legal, its mostly fiberglass, and no tags. thats my issue, lastly, it ahs a 1.5gal fuel cell, so miles per gallon arent an option as well.

[@slugg878]

So if I buy conventional oil and just use it to clean my engine that's fine?. There's no extra steps after that right? Just put the oil in drive 20 or 30 clicks at a slower past then change it back to the oil I had in it be for?

[@jayuski]

If my built motor starts using more oil than OEM I've got a problem bc my current OEM burns a good amount of oil. Also, a side note, does strengthing up my OEM motor count as a built motor if I'm replacing everything but the things like the crankcase and cylinder head?

A rebuilt motor, if done right, should fix oil consumption issues. A built motor usually equates to replacing OEM components with stronger aftermarket parts that create more power.

[@Ethericbikes]

is it the same for dirt bike motors?

[@cMAN88487]

Can i have my turbo installed during break in? Or will break in oil damage the turbo?

[@SupramanTRD]

Having a turbo is fine, I just wouldn't use it. Simply go lighter on the throttle and drag out the revs.

That e39 galant doe 🤩😍

We have a whole series rebuilding that for a coworker that passed away. Check it out! "Dreams to Reality - Jason"

Lolz. You immediately drive the car or put a load on it. If you idle or sit in place revving for the first 20 mins, your ring seal will be very subpar.

I have to break in my engine in a few days. Ideally I only want to rev it until my cooling system is bleed. Then hit the road and go through the rpm range carefully

I saw on one of RHD Kev's videos that he didn't press the clutch on his brand new engine. Something with thrust bearings. Can you elaborate?

[@justadriver]

helps prevent crank walk, lots of guys bypass the neutral safety switch

[@mareksumguy1887]

TunerBattle hey yeah I never thought of that.

[@ностромов]

Hey, btw., it's also while operating the vehicle, always... Don't keep the clutch pedal pressed in for long, when not needed. Most, if not all vehicles don't like it.

Hey mapperformance. I just watch your video and i really learned a lot. I rebuilt my 2002 D17A2 honda civic ex with no experience of what i was doing and i think didn't do it right even though its driving and not burning any oil. The piston rings, i certainly know that they dont gap the way they should and i didn't know that i should put the rings in the cylinder housing and measure it with a feeler gauge also i didn't know that the engine needs to be break in.so, please,can you give me a website for a good brand rings.? The honda dealer charging me $70+ for one set of rigs.
