When I say booted I mean thrashed!When I put the car back together today I did notice a tappet (tick) which cleared when I reved the engine. I will double check the manifold tomorrow. Something else I did notice once when the car got on my nerves, because I couldn't find the rattle I booted the car and I notice a small amount of bluish smoke come out from under the right wing with a nasty burning oil smell. So I pulled over asap to find zero oil leaks and nothing blowing. Not rattles or anything it's as if the car is possessed... this rattle issue has been ongoing now for a while so if I don't find it im going k swap the car because I can't be doing with a engine that refuses to work properly. I really have replaced a lot of parts on the engine and it should at least run right in stock form
There was definitely a smell of burning rubber or oil but I couldn't find anything to back that up (leaks) apart from the smoke after being giving a beating, the crank damper pulley is less than 2months old and was genuine bmw part. I looked at the pulley the other day and to look at doesn't look any different from the day I fitted it. Is it wise to go with a lightweight version without the rubber insert? Also could that pulley cause a rattle if it failed? That pulley is on the side where I can hear the rattlesmoke out of the right wing and no leaks makes me wonder if the crank damper could have a problem, it does happen so might be worth ruling out? They separate.
Cheers for the reply. I think someone has replaced the bearings at some point because I don't think they have done 110k miles on them. I'm going check the little ends on the rods tomorrow see if there's any play then im going check the mains. If they are the same then the issue has to be top end tappets. I ordered a new flat exhaust mani gasket so should be going on where that gets here.the problem is not being able to hear the noise so you may get all sorts of suggestions, if the damper was OEM then it won't be that but there must be a reason for that smoke. The alternators seize on these, casings split, they slow down or can lock up and take some freeing but they're done then anyway. Check it's free maybe.
the bottom end there looks alright, like you say some minor scoring, bearings look a little coloured in places in those pics, some lateral play is ok, check the crank end float perhaps though so you know it isn't loading them, it would have to be bad but I've seen it on a N/A car. Doesn't look like the noise is from down there then.
compressor wire, not something I've seen repaired, I'm sure it'd be possible
