Hello, another 2.2Diesel guy here..
I just got my Dad's old '84 delivered to Oregon (from Idaho) the other day and my 15 year old Son and I are having a blast working on it. It runs like a top, except for a breif shudder that is happening on right turns. The motor seems just as strong as when I was 16!
It is the truck I grew up driving..great memories. NO speeding threat here! (which is why my Dad bought it new, and why I want my Son driving it

)
I'll try to post a pic or two here soon. I should have taken some "before" shots, as it was really dirty and the chrome hasn't seen a polishing rag since I was 20! (25 years ago). Quite a lot of fun..
We changed the shocks on it yesterday, in addition to an oil change(just as messy of a job as I remember, but now at least I have a lift to work with!) and new air filter. We detailed the engine bay some, but I need another 6 cans of brakeKleen, haha. That aluminum Valve cover looks just at cool as I remember. The brakes are good, and she rolls down the road straight as ever. I can't get enough of that rattling engine..
Anybody remember where the water drains out of the water separator? Dad says it hasn't drained anythign for 15 years or so, but I'm not even sure if water in fuel is much of an issue any more? I can't find the spout or drain spot..
Also, can anybody tell me if there is any kind of special antifreeze I should use? Should I use some good flushing solution/compound? A very knowledgeable fellow at NAPA told me to check out my antifreeze PH too, as these motors might be a wet sleeve type or conventional type. Which is it? How would I tell?
Cheers and thanks!
