Maseratitude

As I said just follow the procedure and do align well while the pulley is still hot so that you can move it (by hand). It's an interference fit, be quick and precise. Ok, will do :) 150.000km and bearings in such a good condition ... I doubt. There was no sign at all that this engine has been opene...

Actually the whole bottom seems to be in a quite good condition despite the nearly 150.000 kms. The honing marks are fully visible on sleeves and the machining marks too on the piston skirts (some are a bit more worn). Yes, the rods have brown colour (should be 520 g) and the crankshaft balacing cla...

Finished stripping down the block. The lower main bearing are definitely worn, and some of the upper ones too. Will replace these, but first measure everything. https://s8.postimg.cc/oewf16sfp/20180909_134109.jpg https://s8.postimg.cc/qw868grrp/20180909_134117.jpg Do you know what are these marks th...

Ok it came down, more heat and properly blocking the crankshaft at the back helped.

I would need some help in removing the crank pulley. I have the tool, but I'm afraid that I'll break something. Of course first I've nicked the inner threads where the crank pulley bolt goes (hopefully only the first one or two) because I just threaded in the tool in itself (I don't know how Maserat...

Si non wide band, sonde lambda que j'ai utilisée dans le Ghibli (identique à QP4), plug and play

Je l'ai aussi essayé avec une 3200 GT à partir de 2000 avec le connecteur 3 broches. La dernière pièce manquante pour moi était de définir le "Init Type" sur "5 baud init" dans les paramètres "Connection".

Good to know, thanks for the info.

Thanks for the suggestions. I've measured and it's 0.8-0.9mm. I was also more concerned because of the cooling, but indeed it's not a very wide part compared to the whole seat. I'm a bit revealed based on your inputs, I'll probably go ahead and mount them this way. They only cut the factory suggeste...

Finally got back the heads. https://s8.postimg.cc/hvmansz8l/20180811_085342.jpg https://s8.postimg.cc/un0gucblh/20180811_085459.jpg - Guides were replaced, the new guides had to be drilled out first before reaming because the valves didn't fit, their internal diameter was 6.5mm. - Valve seats recut ...

With some help I've removed the valves. There is definitely carbon buildup on the exhaust seats contributing to the leak, which was also verified before disassembly using liquid. https://s33.postimg.cc/e5zxcb0zz/IMG_20180628_093439.jpg The damage in that combustion chamber is from a foreign object, ...

I did not get answer from Regina, not surprising, Maseralfa explained in Italy you have to call before writting to them :) . He'll try as a professional, he owns a parts business. Oh, great. I've heard the same, and of course you have to speak Italian :) Your head looks like having had strong ping,...

By the way, did you get an answer from Regina chains? I didn't...

Interesting. For me most of the air was escaping through the exhaust valves, some through the intake but couldn't feel anything through the crankcase though the oil pan was not removed. After a long hesitation I've removed the head on the weekend. Glad I did because the gaskets were fully deteriorat...

That's good news. The results are still hard to believe for me, so I'll triple check everything once again.

Excellent ! FIAT STRADA & RITMO Did you compare ? Désolé pour la langue, beaucoup pour Google Translate. No I don't have any, only compared by picture. But I have seen different versions just like for the Biturbo. I think they just started using these, which were designed for smaller engines, t...

Forgot to show these pictures. One exhaust valve is leaking. Is this white color normal? Could it be because of the additives in the modern fuels or it's burned?

Yea this does not look right. I'm sorry I did not read the entire thread. I guess you've checked first that there is a lash between cams and buckets ? Your valves may have been burned if timing/richness was wrong and combustion was continuing with open valves. Yes, double checked to be at TDC at th...

Je pense Maserati 314220100 = Fiat 4433963

Yes, I've fixed the pictures :) Finally did the leak down test, should have done much earlier. The results are really not good, nearly all the cylinders show 25% leakage, regardless the number there a lot of air is escaping at the exhaust valves. https://www.youtube.com/watch?v=XyRx4Bmjmq0 I don't t...
