Stk,

I was thinking about that, but I did not want to depress Jandre until he has checked out other options.

The reading that I have done on Nikasil/Alusil issue is that, if it has not broken yet, it probably wont, and it would appear as if the US was hardest hit on this one due to fuel issues.

And luckaly, it was a chair foot that escaped :)

If it hasn't gone yet then it probably won't rings true however they can go at any time unfortunately.....

I didn't think the US market got the Nikasil lined engines but it definately affected the UK market so much so that a lot of engines were replaced by warranty...Alusil engines are better.
As I said hopefully it is an airleak......

oh, I think thats exactly what happened on mine, I used an energade bottle cap to fix it tho, my cap was completely gone.

lZ, take the engine cover off. By the firewall, on the left bank, Rick found the exposed plastic pipe. Blocked it off and the car idled fine. I need to do a proper fix soon (didn't have the part handy) so when i take the cover off, i will take pictures. On the subject of nikasil, my engine was rebuilt 60000 km ago. the engine was completely resleeved. All 8 cylinders. Not too shabby me thinks.

Jandre go buy some energade quick as a backup spare part!

It's the rubber blanking plug on the PCV brake vacuum hose (that the E34 540 doesn't have anyway)

So basically when he tried to start it, his 540 backfired and blew his plug off... I suggested he now secure it with a large cable tie.

_______________________

On the Nikasil issue, yes it affected SA bigtime, but South Africans never bitch enough about faulty engineering so they got away with out replacing many. I have examined about 20 Nikasil M60 engines and they are all worn at the top of the bore, including mine.

However on further research it's not the death sentance it's made out to be as the aluminium block is hypereutectic anyway (Similar to Alusil in manufacture, Alusil is just a little harder, but both block materials are seriously impregnated with silicon particles) and the Nikasil is an additional coating on the one.

Yes it wears a bit at the top of the bore and the uneven bore causes slight uneven ring wear. A set of new rings and good engine oil program and the thing can last a long time still. I know as I have rebuilt several and none failed.

Oh, and BTW Jandre's has steel sleeves from a previous rebuild, so he never ever has to worry about the Nikasil issue.

The best and by far cheapest fix for a Nikasil block is to just dump an M62 non VANOS engine in the car. The only mod needed is to swap in the M60 front pulley and timing wheel and make a bracket for the Crank position sensor, and modify the CPS rotating plate with a hacksaw. The M60 ECU handles the 4.4 just fine.

Thanks for the accurate description rick. I think i need a 6 pack of energade... STAT...

Well there's this spare M62 waiting in my garage, but the M60 rebuild is strong and better, anyway it's got bigger valves, more lift, more agressive timing, more duration, trumpets in the intake manifold.

The M62 is an awesome reliable engine that never wears out, but it feels the same at 2000rpm as it does at 6000rpm a big fat wideband torque machine that's willing, but I have a real soft spot for the M60, it's just a nicer more highly tuned peaky engine that's fun and all elastic when you nail it.

The best compromise is warangling M60 heads and timing gear onto an M62 4.4 block. 11:1 compression and big cams, good for about 260Kw stock from my volumetric ratio/power calculations scaling up the M60 to 4.4. There's a guy in NZ that did this, and he's chuffed...very

The culprit. See that little piece peering out (centre of photo)? that's the little bugger

This is what it should look like. (again, centre of photo)

This is a bigger view, just to get an indication of the location of the little bugger.

Hi guys,
my '95 E34 540I is idling like it's having a tantric orgasm and it's running exceedingly rich. I checked the one vacuum hose at the rear of the intake manifold and the other blanked-off hoses...all are OK. Next step seems to be the PCV. It seems to be accessible if I remove the whole rear cover secured by 7 Torgue-screws. Is this removal for access to the PCV possible? (without removing the whole manifold etc) and if so what do I need to order from the stealer?
An address that shows the whole caboodle.
