loads... fecking stupid ribe bolts on covers, seized aux belt tensioner.

Half way through job at moment. Got everything off including old cam belt. Need a small ring spanner and cut down star bit to get at last water pump bolt...

Water pump was defo goosed. looks like a reasonable bit of coolant had leaked through bearing and if I grabbed the roller I could feel a bit of play in the bearing. So gotta say a lucky escape and just glad it started showing cooling issues before it chucked the cambelt.

Anyway will get spanner I need today and get new water pump and cambelt, idler and tensioner installed and covers back on. Then gonna take aux belt tensioner into the house and swear at it a lot till I get it freed up then reinstall aux belt (will just change tensioner etc on this later as all bearing feel ok on the aux belt stuff.

Will report back later :)

Think with correct tools (once I make some specific tools for the job rather than trying to figure it all out) I could probs do job in a few hours or less. Space issues hamper progress nicely but some well bodged tools would take the pain away :)

Well it ain't going well spent ages making a tool to fit space... bolt won't budge and now bolt is fecked.

Can't see a way to get the lower half of the moulding that goes to top mount out of the way as only thing that will get bolt off is an Irwin but no room for one.

Cold and really soddin annoyed. stupid car. all it would have taken was a little shaped area in that metal to allow something onto bolt...

Can't see how the **** I am gonna get this bolt out now so pretty much stuffed :(

Not just bad but colossal failure....

Ok wood chisels and hammer in wide inner lip of bolt head and wd40 got bolt moving after 30 mins...

Old pump is pmsl bad. bearings rough, bearing play, impellor totally loose in shaft, also Alfa dealer that fitted it used silicone sealer and instead of folding tabs on gasket round pump folded them under gasket (amateurs).

Anyway, new pump on :), idler in, tensioner on... hope it will be all back together later or tomorrow :)

getting there...

got all filters and stuff coming to do full service. Samco lower turbo hose (designed not to rub on bolt), new VGT valve (as old one broke in hands - pfft, cough) and some silicone hose to replace the rubber hose for said VGT solenoid. Gonna clean VGT actuator, grease arm and check how clean or not it is inside intake manifold (maybe clean the shut off valve and intake aperture - if really bad may take whole thing off and clean it).

Just getting last few niggles sorted so it's perfect. May even clean VNT mechanism as well if I feel energetic at some point :)

At moment there is a little judder in shut off (which guess is shutter valve or something to do with VNT vac hoses). And feel it is just a little down on power at higher RPM in higher gears not a lot but it's a very nice example of a 20v 156 and want it perfect :)

Yeah it was.... it's ok at low\mid rpm in higher gears but seems lacking by 4 -4.5krpm it's supposed to have full 175bhp at that point.... So yesss it is very fast but just no quite 100% all the time. you only notice it once your used to it's initial speed... Not lot down just feels little more constrained then it should.

Will get it 100% then have think about sensible chip like the alfatuner one :)

lol.... bhp is said to be safe going from 175-220ish it can go higher but it's not advised. Some of the better maps are less about peaks and more about improvement but keeping it driveable (so no massive torque lumps or smoke)

Eg Squadra quote

BHP 175 > 205
Torque (Nm) 388 > 424

Not the whole story though as std car torque starts heading downwards above 2500rpm but on the squadra map 420's are held all the way to above 3500rpm.

I would worry about shoving 400 Nm through the 156's chocolate driveshafts, but at least you know what you're talking about and could drive it sensibly.

Not going with the Squada chip... Was just they have figures readily available on their site.

Probs go with the alfatune one as seems they are designed for driveability and not sudden jumps to bucketloads of torque. I guess the sudden jumps in torque would be a lot more stressfull and detrimental on mechanical parts than a gradual increase to the same figure. Though TBH squadra are also well respected and know what they are doing (curves look nice) and they do a medium tune map as well.

Gonna get it so I am totally happy with all aspects of the engine and running and live with it before I decide if i need any more out of it though :)
