sorry I do not, but maybe you can find it in the q4 engine workshop manual.

can this one help you?

Nick,
Is that your engine?

[arjunior45]

Nick,
Is that your engine?

No, and I do not recall where this picture is from. It's from a small collection of pictures {5 or 6 if I remember well} I have concerning a mod to the oil sump {?} to keep more oil to the bottom of it, especially during hard cornering.
It's a 'mod' like the one from the good old GTA {the Giuglia one, not the 155} which I made long time ago in my 'scalino'.
If you are interested I can post more pictures of this 'mod' {in another topic of coarse}.

Would be great if you could!!

Something else regarding this picture, can be the sump took apart without removing the gearbox? Are the sump?s bolt there accessible?

ok I'll post the pictures soon.
Do not know about the gearbox. Once I was told that it is possible to take the sump apart but that's all I can tell.

Edit: I was going to answer the question on sumps, but the 'grale has a two piece sump which is different to the Q4s (IIRC).

[AlfaJack]

The Q4 has the main sump bolted to the block and then another cover on the very bottom

[arjunior45]

well, these are the pictures.
If anyone think they can be usefull in any way, it's just fine with me!

Did not find the one from the Alfa 105 series, too many cds to search, but that's the idea.

[jimnielsen]

thats a very interesting approach with the sump, Nick... have you tried it out? Do you have any other pictures?

jimn~

[Juan AR155Q4]

Thanks Nick!!!

[arjunior45]

No Jim.
I've tried the corresponding one in my series '105' Giulia GT engines and had no problems at all.
You see, it was a mod from the legendary 'GTA' {do not know who first thought of it} and a must for race track use. Keeps more oil quantity at the bottom of the engine and oil pump practically never suck air {or vapors}, even at very hard corners and with the inner wheels up in the air.

You are using the Q4 for race, so go for it.
You could also polish 'like mirror' all the surfaces that are in contact with the oil drainage. A such polished surface keeps less oil on it. Can be done with the rods for example but not only.

Thanks Nick!!!
