here's a simple question...
I'd like to learn how to check the boost pressures on my 83 300D and 85 300SD. I've searched the forum and found a reference to placing a T in the switchover valve line but i'm not sure which one that is. I'd also like to determine which brand of turbo my cars have. Are there any identifying marks? Will a normal pressure gauge work as long as it can measure up to 20 psig? I've read that i should be developing no more than 13 psig under full acceleration.
Thanks to you all for all the valuable information I've learned. Working on these incredible machines is fun.
Mike
