OK so when I bought this thing it had to crank and crank cold before it would start. Once warmed up it started a lot easier (not surprisingly.)
It sat outside for awhile while I cleaned and organized barns to make room for the new orphan. As I recall it still started hard when I went to move it into the barn. I did do a pretty thorough going through on the fuel system. I'm assuming fuel is flowing freely enough as it seemingly had no problem going 60 MPH down the road on the way home.
Checked the fuel pressure per the FSM and it was right on the money. Checked the function of the cold start injector system and that seemed OK. No obvious vacuum leaks but you never know.
So once in the barn I'm getting ready to do compression check and valve adjustment. Now IIRC is was in the high 20s F in the barn and it seemed to start much easier - maybe due to the contribution of the cold start injector? Don't know. Anyway compression numbers are surprisingly good for 360K miles if you believe them. The battery was fully charged but weak I think.
The range of compression is not the best but I expected lower numbers. Do these things build up a bunch of carbon that could be propping up my numbers? I don't have a scope. From what I can see in the spark plug holes the cylinders are filthy.
Valve clearance was also surprisingly good. Once again I expected worse. I though I heard a tick during warm up (hard to hear with no exhaust) so maybe that was number 12 valve somewhere over .030" clearance. Yes I set these cold but I'll come back and check later anyway.
The rocker box is disgusting.
I'm not pulling the head right now but that bothers me.
PCV system completely plugged up stem to stern.
I had to burn that carbon out of the metal PCV pipe. Now I'm a big fan of "While you're in there....". I've read some here that have a different point of view but that's how I roll. I'm never in a hurry to get a project done. Soooo...as Dave (KAWAZX636) over at Yotatech says.....bakin' cookies.
The valve cover is very much part of the PCV system and that too is completely plugged - all the passages between the inner and outer stamping. I can just hear the old man now. "What? You don't have time to homebrew but you have time to hot tank your 3FE valve cover?".....or something like that.
So down the rabbit hole we go. More to follow.
