must be one of those "spare" parts that you are left with after the rebuild. It looks like someone went through a lot of trouble to design it and then did not plumb it to the block. Weird.

Here is a picture

What the heck is this

I opened up my project motor and found this strange U shaped metal tube and rubber hose mounted to the pickup of the oil pump. I will try and post a picture. It looks like it is intended to put small streams of warm oil near the pickup. The rubber hose was not connected to anything, and I could not ...

WT trade - shifter

I am building a Milano transaxle up to install in my GTV6. Since I don't have all the isostatic parts, I would like to keep the splined shifter input shaft. I have the cross drilled shifter shaft from the Milano to trade for a splined shaft from a GTV6. I'll even throw in the partial isotatic compon...

Sorry i haven't replied in a while. Been distracted by many other things. I think you are right that the linkage was bent slightly. Had a clutch input bearing go out after this repair and pulled it apart to get at that. once it went back together, the shifter feels fine. When I finally get the rebui...

Shifter forces

Maybe this is covered somewher in the forum, but i am not sure what to search for. I replaced the De Dion and watts link bushings with teh performatek pieces this weekend (very effective, car feels much better). At the same time, I replaced the broken RH transaxle mount. I did not disconnect the shi...

The shop I buy my bearings from gave me a couple of shims for free. Try you local bearing supplier. You can measure the stack with your current shims, then measure your current shim(s) and adjust. Just like setting the valves, only easier. You don't need to worry too much about OD and ID of the shim...

back to your original question Can you swap guts with the Verde box and make a decent GTV6 box. I am currently working on a Milano silver / Verde compilation. I would think that the GTV6 box is not that far off. You should be able to swap the ring and pinion from your GTV6 into the Verde box, keepin...

Buy Jim K's book "How to Power Tune Alfa Romeo Engines" It not only has pictures, but provides dimensions. I used this to make the removal tool fro my V6, and will do the same at installation. Remember to check the service manual for installed guide position. the intakes bottom on the tool...

"special" V6 valve shims?

I was reading technical bulletins on the CD yesterday after finishing looking up information for the transaxle. I know, I'm boring. I came across two bulletins that stated very clearly DO NOT use 4 cyl valve shims in the V6 - they will fail. !!!!! Now I know what the little groove in some of the shi...

Most places out here use a pressure wash cabinet for cleaning aluminum parts. Your cam bearings should be OK through that (they are similar to sts chevy cam bearings that woudl get destroyed by a standard hot tank - of course the standard hot tank would eat your heads too!). Best to talk to the mach...

Lightening both flywheels probably won't help the syncros much (they are disconnected from the accelerating mass during shifting). However that will allow the engine to rev faster, potentially allowing you to double clutch faster (I never could get this technique down to where I like it and just rev...

gearbox math

Very interresting. I have been doing some math and think I understand why the second gear sincros don't live long. Look at the difference between first and second gear ratios for the GTV6 for instance. It is 1.54, while the difference between the 2-3 ratios is .71 and it keeps going down as you move...
