busted my input shaft on my 350i on the way to lydden race track too see the big 520 wedge scream round the track,
i got home using only 4th gear, i got my self a good second hand box and though i be safe so i replaced the clutch and now i just got a phone call to say that the crank is showing signs off wear so that has been sent off for a grind it just goes on and on,

but am sure when i fire her up and cruise down the road it will be worth it

Chin up, smile and all that. Been there etc and it is well worth it when its back home and doing what it should.

At least you got it home ok. Stay calm but... with the engine out make sure that you check the camshaft and use the opportunity to clean and paint the chassis.

the top end was rebuilt about 1000 miles ago i used the 218 cam kit springs follows etc and had the head skimmed vales re-cut and a bit off a polish,

Normal thinking on this is to try to run in with minimum load on the engine. As per regular running up to 2500 revs when warmimg up then up to say 5000 but with as little load as possible so no hard acceleration, pay particular attention to which gear you are in, tyr to drive at 2500 to 4000, don't labour the engine, especially up hills but don't thrash it either. 1000-2000 miles should be enough. I would guess that you were probably thinking of doing something like that anyway? I'd also change the oil then; it should be OK but don't take chances.

thanks 19560

i will do as you say and play it safe as it will be a while before i can spend any more £££
