Oil Changing...
I used rather alot of graphite grease when assembling my engine, on the cam, timing gear, oil pump etc..
This has made the oil a graphite grease colour after about 2 hours off runing lol. Is is worth changing it yet or am i going to harm it that way?
If i do need to change it, should i use a flush - or will it gradually come out with regular oil changes?

I'd change my oil.
Never used graphite grease myself. Always used Wynn's oil treatment for bearings and the recommended lube for new cams.
I have always changed my oil on new/reconditioned engines after 500 miles as running in the engine will produce worn material that ends up in the
oil.

Agree wit nitram38 but remember you can't run in with synthetic oil , use a good mineral based oil then flush and change to the recomended oil
for your engine!

i've never used grease of any sort in an engine, apart from that red cam lube stuff or vaseling to prime oil pump.
I don't know what effect the grease will have, it is not like you have added sand.
In reality I doubt the small amount of grease in several litres of oil will make any difference but for the sake of a tenner spent on GTX, why risk
damaging engine?

I used that graphite assembly grease - once the engine had done around 500 miles I changed the oil anyway. No problems seen.
I can't see that any extra anti-friction content is going to upset the engine...

If the stuff you used was called Graphogen or something like that then just change the oil after 500 miles. Better to use running in oil if you can
when filling for the first time after a rebuild or a cheap oil of the correct grade

If you are using new pistons or rings it could cause the piston rings not to bed in ---- potential major problem.
The problem is it lubricates a little too well for the the piston rings to wear into the highs and lows of imperfections of the bore.
This would worry me to the extent that I would flush through the engine a couple of times adding 500 ml of autotrans mission fluid ( Dextron IID )
as a flushing agent.
If it was used to lubricate the pistons in the bores when assembling personnally I would strip the engine and clean everything with gn wash
thinners and roughen up the bores again.

Just remember that Burton Power use Graphogen for all their engine rebuilds (according to their literature). It doesn't seem to do their
engines any harm.
I shouldn't worry about it too much, and just change the oil after a few hundred miles.
