From what I was told, most GTV6 and a few of the earlier Milanos (mine) used cast iron type valve guides, which were documented to occasionally cause sticking or slow valve operation under very high engine temperatures and high RPM. Perhaps they would expand and become smaller in the ID? Later engin...

Zamani: I just realized I had been mistaken about you at Streets of Willow 3 years ago. It was your brother Nizam whom witnessed my 2.5 detonate on the track and helped me troubleshoot it. Turned out to be a sticky valve @ 6,500 RPM that hit piston and spewed valve shards through the heads. Destroye...

Zamani: Thanks for the tips. I dont recall exactly, but I believe I simply wiped the cylinder with a rag with a very small amout of SAE 30 on it, then wiped it off the liner with a dry rag. My opinion is that a bit of folklore exists regarding assembly procedures. Consider this, for 50 years the sta...

Zamani: I did not apply the meticulous care that you did to the liners. They came back from the local shop looking pretty clean, but perhaps on a microscopic level they were not. I remember putting a rag w/WD-40 through them and did not recall any residue. As the honing and other machine work was no...

Hmmm...might be a legal disclaimer, but an admittedly unscientific review of comments on the WWW reveals that oil consumption on V6s is all over the place...and that is both for original factory engines and those that have been rebuilt. I've read reports that vary from a smoking 250 mi/quart (!) to ...

Murray: Thanks for the report. Hmmmmm...seems strange that this might occur due to the rehoning of our liners...this is a traditional procedure done over and over on a multitude of engines without adverse effects. Perhaps the honing is an extremely critical process and neither one of us got it quite...

3.0 Excessive Oil Consumption After Rebuild?
My fresh 3.0 (only 3,000 miles after rebuild) is burning about 1 qt. per 750 miles, using Castrol 20W-50 GTX. This is during rather hard back road driving, where the car is always up over 4k+ RPM and often hitting redline. Perhaps this topic has been covered before, but I could not find "typica...

Milano LSD: Worth the time and $$ to convert, or not...?
My Milano Platinum had the transaxle replaced by previous owner with a NON-LSD 4:10 unit from a Milano Gold. Bummer! I've recently replaced the 2.5 with a totally rebuilt 3.0 and S cams. Now that I have gobs more torque, I can pretty easily break the inside wheel loose when accelerating hard out of ...

Steve: Sorry for my slow reply, I have been off this board for a while, summer holidays and other things... Thanks for the info. I assume you discovered this via O2 sensor readings off the MS program, right? Your findings concur with those of Greg...that stock injectors are borderline, even with a s...

Zamani, David: Thanks for the replies. :D Zamani: Good idea! However, the issue of connection to air temp sensor is one I will have to figure out. With the original AFM in place, I can use the one in there for MS. I can plug the cable in for my smog inspector, pin the flap wide open, tune MS for low...

Are Bigger Injectors Needed for 3.0L w/ MS?
Just completed a total rebuild of my 3.0, but no performance upgrades were done except a new set of "S" cams. Exhaust manifolds remain stock Alfa, although I plan to eventually get a pair of hi-flow cats mated to custom down pipes. Next up is an MS conversion, for which I am now gathering ...

Thanks for all whom replied. :) I ended up finding the old 164 nipple in the trash bin and salvaged the theaded part. I silver soldered a 1/2" brass nipple to it and away we go. The 164 engine conversion document on this site is a great resource. What it does NOT say is how impossible it is to ...
