take a look . if you dont mind , what do you pay for that test ? might try them myself , of course its a series of results/tests that really mean anything as one will see any significant change from what one sees as normal. different engine designs (materials base) will give differing results high chrome/aluminium/copper levels would not be good news, if i saw an odd result ,with no visable conditions i would repeat the test at half the previous interval and decide what to do based on the results along with the ussual compression ,hot /cold oil press test an filter interview.

That example report looks rather good! I did query the results and they said they look normal. The high amount of iron (from the rings) is what worried me the most, I have never seen another one that high. I would mind using another tester as the oil I had tested only had around 3000 miles on it I think.

I thin kit was £49 from memory.

that price is not bad, the iron thing, there are other sources of that, wear on timing gears and chain spockets to name a few the lab can normally advise on that as the material of the rings differ and one high result without any other evidence (not as in yr case of failure ) would have me concerned but not yet reaching for the parts manual . have you interviewed the oil filter? to see whats been collected . if there is anything much there you will be looking at a full strip to get everything, inspected, cleaned,crank, oilways ect even if you were to get away with bearings/seals/ rings and gaskets . too much of a bitch getting that lump in/out to take any chances with that i would say . get yr other lump in. and maybe sort yrs out as a spare or to sell on after. or better, sort yrs out , know its good and lift the other out again run the car a while ,if ok sell the second motor on again ,keeping all yr paperwork/car origional provided the rest of the car makes keeping it origional a worthwhile proposition ?
see explanation of element sources fe ,gears ,shafts ,rust ect also see Ni and B

I'm pretty sure alusil blocks can be bored and honed - as mentioned above there's a procedure using felt pads and an abrasive paste that wears back the aluminium to reveal the silicon crystals.

Not if the scoring is through all of that coating, which is very very thin.

Interesting thread here about alusil blocks / fitting liners (hartech reply is very full - think that's the business they are in)

There is also Westwood cylinder liners - they can do bespoke nikasil or ductile iron - I obv have no idea of the costs involved, but no doubt it'll make you weep!

Christ, Nikasil liners on the R-1830 were about $800 15 years ago, admittedly they're bigger than even an MB would take but that was straight OEM pricing. I'd reckon you'd be looking at a grand for the part, then you've got to have it fitted. I presume press fit?

I was driving very near to where Alex lives and I see still not sorted out

There's no "coating" in an alusil block - the hypereutectic nature of the alloy means the silicon crystals that essentially provide the bearing face of the cylinder are evenly distributed throughout the aluminium of the entire block. Once a cylinder is rebored, the honing abrades the aluminium back to expose the harder silicon.

if that's the case then mild scoring hasn't damaged the coating and if the rings are in one piece then can be ignored..... don't believe you

from a post on Porsche Club of America

this disagrees " It also states that if Alusil was used they were basically a one-time-use since they can't be honed and they can't be re-ringed successfully"

https://en.wikipedia.org/wiki/Alusil is of no help whatsoever

 

[ajlsl600]

what a ****** surprise and prob the prime reason benz ? and others? use the system . i do know that given time and enough volume someone ussually finds a way .but i dont know a way . bet the yanks do tho . but Wont be dealer/factory approved. i am just glad my next car will probrably be my last, they are getting like fridge /freezers just as you think all is ok you need a new one , the compressor is 80% of the replacement cost, at least my last was...and it was only 5 yr old the previous was 20 !!

Strangely, KSPG (who make alusil engine blocks) seem to think otherwise:

Unfortunately, due to personal circumstances, I have had to sell the project on. I am starting up a second business and have moved quite far away from WG-MB. As a result my absolute pride and joy must be passed on.

I am on the lookout for either a nice 216 600 or a nice (not overpriced) 215 65 amg.

The CL65 AMG's come up very very rarely for sale, so if anybody spots one, please let me know.

For the first time in 8 years, I am MB-less

 

[V6Matty]

bloodyhell Alex, that's was a bit of a shock and a bit of a shame, as I'm in the market for a 215 at the moment and yours would have been very nice

 

[Naraic]

You may be MB less at the moment but I can't fault your ambition for a W216.

 

[television]

The 600 in the CL range were only sold to 2007, just leaving the 65. these were not changed much from the start, small mods in 2008 where the car went over to a single battery, and the facelift at the end of 2010

Sh1t Alex, sorry to hear of this, very sorry indeed. I did think that you'd been quiet for a while.

Indeed, It had everything needed done, and more! I feel disillusioned from the big chunk of work already put into it tbh.

So no 600 after 2007?
