Whats the best way to run in an engine... just rebuilt my frst engine, replacing piston rings, turbo, etc etc etc


want to make sure i dont fook up

 

nail it......

 

now thats why im confuse


Some people been telling me to take it easy... then others saying dont be a pussy

 

Run it in on mineral oil and just do 1000 gental miles mate, after that change the oil & enjoy.

MASSIVE

 

Run it in for about 10 miles making sure no leaks then drain oil re do with good quality and then drive it like you stole it.

 

difference of opinion again ,
well i just done 4k after new build and now its fuuked! i drove it lightly for the first 1k miles !

Your post is the reason i posted

 

pmsl this is pre set up

dont want to put a piston through the block

 

Persionally I'd get at least 2000 miles under her belt. Remember, the better you run an engine in, the better it'll ultimately be..............

 

well my rings didn't bed in driving it gently, causing me a rebuild, will be thrashing it next build, well slightly more load me thinks than thrashing

 

100 miles on cheap shit oil, drop oil add new filter, then every 200 miles drop your oil and replace with better oil working your way up to fully synthetic at 1,000... then get it to stu for a setup.

Don't take her above 3,000rpm while in this running in period and also try and run it in at different rev ranges.... keeping it at say 2.500rpm for a long distance could glaze the bore's i've been told, so just run it in on everyday roads, stopping and starting etc.

DO NOT drive it like you stole it as you have put a new turbo/actuator and large front mount cooler on and you will have no idea of boost/fueling etc.

Roll on tomorrow to get her fired up, can't wait

 

is there any proof other than some home made website to prove that hammering it works

engine have been run in gently for years and there is proff that that works. presonly i can't see any harm in taking it easy on shitty oil for a good 3000 miles

 

loving the differance of opinion

im going to help you here, ive worked in the motor industry now for over 15 years, and have driven more than 15,000 differant cars, i have driven old/new.

the best cars that have ALWAYS had the least problems, but had the BEST performance have ALWAYS been the loan/courtesy cars we have had at any dealer franchise.

ask yourself why ?


please comment below.

 

How are they run in though? Maybe they had been run in properly... THEN had the shit ragged out of them

 

dude you got a new engine done already?



M-A-S-S-I-V-E-!

 

i've always heard to run it gently for between 500 and 1000 miles.
then get good oil in and get it set up nice.

but like said above, the better u treat her now the better she will be in a few years time

 

i think there is a write-up about running engines in, in the front of the burton power catalogue. Some good info in thier. I always thought 500 easy miles then slightly harder (no more than 3.5k) was the way. Did this with my mk1 escort when i rebuilt it, and that took a right beating. make sure you use cheap/crap oil like own brand stuff for the first run as the fully syns tend to clean the engine and you dont wanna do that initially.

 

trust me pal, the dont do 'gentle'

i mean who doesnt rag a courtesy car ?

for me ,i run the car up to temp in the garage, check for leaks, change the oil, then its as simple as a gentle ride round, up/down the box, small amounts of boost pressure, no constant cruise for approx 100miles check for any probs ( correct as ness) change oil , give it full chat for a few miles, change oil -

start special stage 1...................

i will have a new engine fully ready for competition within a day or so.

 

oh and p.s

i would never ever use synthetic oils.

i have my reasons. if you like it , good for you, i dont.

 

Most brand new cars are ragged shitless from cold by the delivery boys, boat loaders etc etc. Trust me, I know

Run it in hard, warm it through by driving gently then use 75% throttle to take the revs from 2k or so to 5k and let it overrun back down and do it again. repeat a few times then use more throttle and more revs. Dont let the engine labour, do 50-100 miles like that then drop the oil, replace with decent stuff and thrash it.

 

so there ya go,a nice clear as mud answer
run in couple hundred,thn go up from there

 

lol

in my line of work i get hire cars very often. do i treat them with respect?

do i fuck

one instance:

i picked up a brand new 2.2 mondeo tdci

it had just 13 miles on the clock.

its about a 20 min drive to the motorway from work, traffic etc so not caining it.

got it nice and warm, and with about 30 miles on it it was motorway time. wound it up to 140+mph lol, got home and realised it had 6 gears pmsl

anyhow, it went like fook, didnt have any probs at all with it.

but if it were my car, asda do oil for Ł2.74 for 5L of 20/50

use the cheapest, shittest oil you can buy. take it easy for 50 miles then replace oil filter - same oil

then give it a bit more, dont labour the engine tho make sure it revs freely etc and dump the oil and filter after another 100 miles

then use some good oil, not synthetic tho - still mineral

and give it a bit more for another 100 miles

oil and filter change, drive it like normal

thats what im gonna do anyhow

 

oh ah

second instance

2 and bit K miles on this 06 plate one

 

ginge is running in my new engine for me at the minute (new rings/shells/gaskets etc...)

Done it text book from what i have been told by keeping it below 2500rpm, driven to work everyday so revs always changing. Changing oil at 500 to better stuff, then getting a slightly harder 500 miles with a little boost, then maybe another oil change and set up

 

cheers for all the input here people

Still a bit confused as there is conflicting info from people who know a hell of a lot more than me....






p.s.... Radders... MASSIVE

 

No idea if it's the same with cars but with 2 stroke motocross bikes if you rag the shit out of your bike out of the box you're likely to get a bit more power but have a lot shorter life expectancy of the engine. Best way to run in a race bike as you get more power but the piston isnt used for long anyway so ragging it doesnt matter. However if you're running in a bike to ride alot and want it to last longer its best to run it in gently.

HTH

Probably doesnt help one single bit though

 

 

not sure why people say take it easy??? if it's been put together right there's nothing that's going to break

when i did mine, i ran it up to full temp, then did 20 miles of light boost driving (literally just about 2-3 psi) then dropped the oil and went from there driving normally with gradually increasing levels of boost.after about 500 miles it was given full boost plenty of times and i had it re-mapped after 800 miles,where it was obviously given death

 

Been there do =ne most if you are to gentle you will glaze the bore so 500 mile up to 2k then done another 5 3,5k then set up after that 400 BHP can the ass out of it

 

just out of interest, say the new 'hire cars' we are talking about- by the time they hit the road they have half decent oil in so can take a thrashing

if you are running in a cossie on cheap shit Ł2.99 oil to bed the rings, then you thrash the life out of it surely the turbo will suffer?

 

what part of the engine do people think they are running in?

 

As long as your oil temps aren't getting too hot and the shit oil gets changed really often (200 miles max) it'll be fine.

 

okay glad we cleared that up then
