Hello!
I am new to the Mitsubishi crowd and just picked up a 2008 Evolution GSR! I am currently installing a new short block for the car and noticed something in the timing area. I bought a new short block from Mitsubishi (Part number 1000B021). The privious short block was cracked and started moving the exterior hardware over to the new block. I noticed this hollow nipple coming out of the block. Then proceeded to see that the mounting for this peice was NOT on the new block. Is this needed for the block? Is it something Mitsubishi did away with in later years of the Evolution? Any help is appreciated!

the one with the tube is an oil squirter for the timing chain (old design). Sometime between 2010 and 2011 Mitsu changed it up and just use an orifice (updated design).

I do not know why they made the change. I assume because it is cheaper.

My Motor build went the other way around. Picked up a used block from a 2010 (has the steel tube piece) to put in my 2011 (only had the small hole.)

Shouldn't be an issue.

Would need to seek the input of an engineer-type person to tell if one is better.

 

I concur with the above post. I built a motor for a good friend of mine with an evoX And ran into the same issue. We did some research and after hours of reading that it was a manufacturing change and not an error we proceeded to build the motor....it went on to make over 475whp without issue....hope this helps!
