Well my 65mm pulley I ordered from IBF in Poland left Poland last Thursday via GLS post and it's now sat at my local Parcel Force depot ready for delivery tomorrow (not bad going IMO), I've also booked with Eurocharged for the end of the week, can't wait......

In preparation for it's power hike I treated it to some new parts with a new fuel filter, new panel filters I also have a Code 3 intake style modification so it should breath great anyway and also a new set of NGK Iridium plugs.

While switching the plugs I started by first removing 1 plug per cylinder and carrying out a compression test for no reason other than to make sure the engine is in good health which they are all good compression and all within 4psi of each other and all the plugs (Bosch platinum tip) are all in great condition showing there all firing clean.

Fuel filter and plugs were last changed 32K ago:





I made a tool years ago to get the plug leads off these Merc's which makes getting them off easy and as usual it made light work of getting them off especially given the limited space on the rear cylinders it's not pretty as it only took about 2 minuets to knock up but it works great:







While under the air boxes I addressed the breather box leaks both sides more so the left bank, it had new cam cover gaskets a short while ago but they didn't see or realise the breather boxes where also leaking:









That leaves just a few more jobs to get done as the parts are not coming till tomorrow so I'll know what I'm doing tomorrow night.

I noticed the oil filter housing to block and oil filter housing to oil cooler are both leaking so I ordered the genuine seals which should be delivered tomorrow morning so will also change the oil and filter at the same time:







My pulley will also arrive tomorrow so I'll pop that on too and while I'm at it I change the bearings in both the Idler pulley's and the tensioner pulley with the new uprated ones I have 6303ZZ bearings for the idler and tensioner and for the supercharger idler I have a 6203ZZ , the stock bearings are rated to 15,000rpm and my new ones are 17,000rpm and just generally a better quality bearing and there a hell of a lot cheaper than new pulley's.

Final bits finished this evening with the 3 seals in the oil filter housing swapped out and a fresh oil and filter and finally the new IBF 65 mm pulley fitted:







On the way home I had the Torque app running on the phone to just see if there was a difference so I accelerated not to hard and only up to 5000rpm and my boost reached just under 18psi so it all looks good and on target,

I wont push it any more till after the remap at Eurocharged, I know people do just bolt the pulley on and go but I'd rather know for sure my fuelling is running spot on.

New supercharger idler fitted today I wanted to swap out the bearing but I was able to pick up a Febi which is the make of the genuine Mercedes one I removed for just £20 so wasn't worth messing around with:



Check out this video I made of the old idler. Caught it just in time I'm thinking, strangely it made no noticeable noise on the car under tension luckily I checked all the idlers and tensioner when I fitted the new 65mm pulley the other night:
