500 miles @ no more then 3000rpm
250 miles @ no more then 3500rpm
250 miles @ no more then 4000rpm

Then flat rack but would you still be careful for a while ?


As for the brakes what should i be looking out for be aware of with new brakes

cheers for any advice

dont forget to use mineral oil and change it at least twice

MikeR

Please explain Pete and excuse my ignorance

mineral oil will let the rings and bearings bed in if you use synthetics which gas to much friction protection they wont ,run in on cheap mineral oil then when its done change to synthetic

gurnE

Do the thousand then use it normally.

In fact thrash it from 0 and you'll have more power

Will use more oil though

MikeR

Thanks Pete

Will the oil that is in it to start be good enough

any mineral oil do not use semi or fully synthetic untill your ran in,good old Duckhams will do the job of Ł5 glug from Tescos

Chrissy_bwoy

cheapy oil to let everything bed in nice

cheap and crappy as possible

ryan_belfast

Just rake it from go, most new engines are run in for 1000miles in the factory anyway so the day you get it, rake the shit outta it !!!

pugo

I personnally would never put shit oil in one of my engines, i would use only fully synthetic if i was you, never labour the engine and drive it like your mum for a couple of hundred miles and then slowly build the revs up, 500 niles change the oil and carry on increasing the revs over a short period then hurt it

you are only bedding the rings in that is all and to be fair if the honeing is real good, that should happen in the first 100 miles any way

a little knowalge is a bad thing thing mate I suggest you do your homework first on oils and engine building before posting such rubbish which could cause damage to someones engine

Garage19

The best way to run a new engine in is:

1) Make sure up to running temp. Check oil temp not just water.

2) One run at 1/4 throttle.

3) One run at half throttle

4) One run at 3/4 throttle

5) Full throttle, now run in.

I know people won't belive me but i have seen the results of run in procedure tests.

If you do not have enough cylinder pressure to push the rings out right at the beginning your rings/bores will never bed.

The worst thing you can do for a new engine is to putle around at 1500rpm for 1000 miles!

If you run in 1000 miles and take apart you will get brown sludge below piston rings caused by blow by and un bedded rings. Run in the fast way and you will have clean piston skirts and a more powerful engine.

MikeR

any other opinions guys,

The above posted was what Mitsu have told me to do but the sales man did say it is excessive but there is also a warranty involved and a very nervous misses if it does go wrong


Mike

i am an engineer working for bp oil....i have worked in the development of many oils , mobil one being one of them and you are a car breaker

and your telling people that they have to bed shell bearings in

yes your spot on a little knowledge is a dangerous thing



For the guy that is running his engine in, let me give you some advice , Cosworth the highly reputable engine designers, builders and manufacturers who are responsible for many F1 and other wins in motorsport recommend that you use fully synthetic oil in your YB engine at all times(including running in), i am in no doubt mitsi do exactly the same, however if you wish to take the advice of an unqualified person(in engineering or chemistry) then knock yourself out

we got a brand new mondeo 2.2 tdci hire car the other week, it only had 13 miles on it when i got in.

got onto the motorway with about 20 miles on the clock, and had an indicated 140mph within a couple of miles lol. had the car a week, didnt miss a beat

went like fuck too

tonyk

Jock stick with what mistubishi say, at the end of the day the provide your warranty. I would just use the oil your car came with.

For others reading this guy bought a new evo 8 320, its not a rebuilt rst engine like his sig may make you believe.

pugo

i had realised that , however i still wouldn't put shit oil in any turbocharged engine cvh or not

run it in on cheap oil

start it up run it upto temp and leave to idle for 5-10mins drain oil change filter

fill with crap oil and drive the car don't let it labour, make the engine work but don't flog fuk outta it.

engine must be allowed to use a varied rev range and engine loads find a nice country side route and go driving for a couple of hours

change oil and filter again (did mine at 500 miles)

used semi-syn oil 15-40 and did another 500 miles using more rev between gear change

once i reach 1000 miles drain and flushed oil & fitted new filter and used a good quality semi-syn oil and just need to get it setup again now

i change my oil and filter every 2000miles and always let me car warm up and cool correctly


just read post above mine if its a new car use there recommended oil thought it was a newly rebuilt motor

just hoon it, its not a cossy, it wont break

Dirty Harry

iTrader: (12)

yea right I knoe nothing youtr probaly some YTS tea boy,tell you what mate go ask any cossy engine builder how to run one in,I not talking about new car dip shit,as there ready to go from the factory,I know nothing of oil,emm let me see I only just used to have all my oil tested my the supplier in my race cars,Only a car breaker ehh

pugo

well perhaps you need to read before jumping in, as its an evo we are talking about

well one thing for sure, you can't spell

actually the bores and rings are no different from a new car to a rebuilt one (if its been done correctly)

yes and i was probably one of those that tested and developed the oil before you got your hands on it and tested it after you used it

now off you go and bed your bearings in.....

Dirty Harry

iTrader: (12)

so let me get this straight your an expert on oil and your saying you do not need to use a cheaper grede mineral oil to run a Cossie or an RST engine in after it has been built ??
For the record new cars are run on low grade oil untill the first service
if spelling is all you can moan about mate I will take my time on the key board,as I aint got time to keep picking you up on your little knowlage of engine rebuilding

pugo

i rest my case

do you know what happens to mineral oil when you run it through a turbocharger seeing the colossal temps that are achieved.....and then you want to run it through the rest of your expensivly rebuilt engine



oh and don't think because you are taking it easy you won't see the temps

Dirty Harry

iTrader: (12)

Iam sure your not stupid to think you run a cossie engine in with any sort of boost do you,so no the turbo wont even get hot,
have you ever seen an engine run in on synthetic oil.

pugo

yes i have, as i stated earlier i worked for mobil in there engine test facility helping with mobil one(amongst others) so probably seen about 10,000 engines run in on synthetic and measured all the componants in a temp controlled enviroment

why is that then have you diverted the exhaust gases elsewhere then

and surely your not stupid enough to think a turbo in normal running will not get very very hot ?????

S2martin

When i had my engine rebuilt i also bought a new turbo from turbo technics and i was told if i ran non synthetic oil through it the warrenty was invalid.

When i told my engine builder about it he said that after all the money i spent on my engine i should run it from day one with the best possible oil anyway.

So thats what i did and it has been flawless since

somehow I dont think it would fuck up as you put it,as I stated before Iam talking about a Ford motor my mistake for looking at the guys sig with a ERST in it,

Lol how old are you two, besides i do understand how pete thought it wast the guys RST

MikeR

Sorry i thought the Mitsu bit at the top was enough to say it was not my rst.......


I have learnt though that there clearly is a difference of opinion here,
