Hi all i need some advice ive just had my engine rebulid with 4 new standard pistons new uprated big end bearings uprated oil pump and water pump etc wanted to know whats the safest way of wearing the engine in and how many miles it will take heard mixed reviews.

At the moment its runinng 10w 40 semi syn oil and ive done 100 miles was thinking of changing it at 500 miles for the same stuff then at 1000 put mobil one in does this sound ok?

Just what it to be safe before i get it set up was gonna go to devil devolopments in littlehampton has any one been there or know there ok.

 

as said realy i would do a few oil changes along the way 1000miles seems alot tho but each to there own i gess.

as for devil devolopments i have spent the last few weekends working down there. lee is top bloke and very helpfull (i was working till 4.30 am last saturday ) but if it needs to get done then it needs to get done

 

thats a late one lol spoke to lee today and he recomended to change the oil in the morning to a 10w40 then drive it down to them which is about 50 miles and then change it for mobil 1 and get the car set up? since have the car back ive done 135 miles checked the oil dipstick today and can see tiny bits of metal is thta right?

 

who rebuilt the engine? very very fine shavings of metal can work there way through an oil filter no problems. i would go for an oil and filter change soon then

 

is it a fiesta turbo engine?

dont hammer it but dont be frighten to give it some boost, plenty of overruning, varying revs and a bit of boost

i would be using mineral oil to begin with then change to semi then change to full syn

 

Owens garage in haywards heath rebuild the engine.
Gonna change the oil tomo yeah its a fiesta efi engine.

 

Is that right for a rebuild engine to have tiny bits of metal in the oil?

 

use a cheap mineral oil on your fresh new engine NOT semi for the 1st lot of miles cuts down the chance of the rings glazing in the bores m8 which is what you DONT want.

 

ahhhh no problem then be warned tho you must insist on the boost presure you want to run as he loves "2bar boost!!" lol

only joking you wont be disapointed

 

a little, but not alot and it shouldnt be big particles either, how much have you got? and how big are the particles?

get a magnetic sump plug from MSD!

 

there very tiny shavings that i can see on the dipstick like 1mm if that since ive had the car back they put 10w 40 in it shal i change to mineral oil at this stage or can it damage my engine?

Will just be happy to have my car set up to 16psi or less just want it to be more reliable and not go bang after the money ive spent on it.

 

Can the rings still do damage to the bores as have only had new pistons and rings and new uprated bearings i dont think the engine has had any manching work done to the bottom end to the bore etc.

 

what managment are you on?? and i hope they are smaller than 1mm??

 

im on omex magement
when i take the dipstick out could see like 5 little spegs of metal on it dont know what size i can say they are there small though.

 

there will be small bits of metal floting around the oil as it is running in and all.

very good ecu

 

Thats ok then was getting worried then lol yeah have the omex magement newman cams t3 turbo pro alloy intercooler airtec rad filter exhaust uprated fuel pump water pump and oil pump and uprated big end bearings so unsure what power it will make at 16 psi is this a safe amount of boost for this engine or shall i go lower?

 

I wouldnt listen to anyone on the internet personally, unless I rebuilt it myself and didnt know any better..

Ask your engine builder what they would do to run it in, that way if it fails, you can go back and say "I ran it in like you told me....." instead of "nah I listened to Tam on passionford who said give it 2 bar an bounce it off the limiter"

 

what rod bolds are you running?? i take it standard rods and pistons?

 

the garage i had it build at said 10w 40 would be fine i know what you mean just wanted advice as im a chef not a mechanic.

Yeah there new standard pistons put on tto the old rods i had arp bottom end bolts put in is that what u mean?

 

ahh good the standard rod bolts are a week point in the cvh imo.

i would not aim for a boost presure to run i would be aiming for a power output.

stick to around the 190 mark with the t3 turbo

 

Drop the oil to see if any metal comes out with it, and as said you should be using mineral oil for running in.

 

i agree should be using mineral oil and get rid of that oil with the metal init
