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.

Checked the oil dipstick today and can see really tiny bits of metal gonna change the oil tomo for 10w40 halfords or castrol spoke to devil devolpments and they asked me if the the car is smoking ive had no smoke since ive got the car back and they said its prob worn in ive done 135 miles since ive had it back they recomended to change the oil in the morning then drive it down there which is 5o miles then change the oil to mobil 1 and get the car set up?does this sound about right?

if its a cvh whic i guess it is that should be ok providing the company you used to do the machening did a good a job. and all the tolerances are good. your engine will be run in after 200 miles
