Pinging wjhen lugged
On my '85 F-150 (300-i6,EEC-IV), after I get it warmed it, when I am kinda lugging it in high gear or slowly accelorated, it wants to ping. My first thought was EGR. So I looked under the hood, and, alas, no egr valve. I haven't pulled any codes (since pretty much the last guy hacked everything up beyond belief), don't have a timing light (going to pick it up tonite from my folks), and don't want to rebuild the entire emissions system (it is a beater, and I don't have to pass emissions, and I'm not driving it a lot), I'm wondering if I slap a new EGR valve on and hook it up if that would solve the problem (going to check the timing b4 I mess with anything)?
btw, how many degrees is this thing supposed to be at? 10 degrees BTDC?
also, my factory temperature gauge isn't working. If I used the hole on the gooseneck where there is a sensor (thats no longer in use, suprise!) if that would provide an accurate reading?

I thought it said 10 BTDC but someone spray-painted over a good bit of it..
I did put a light on it, but I couldn't find a timing mark. I rotated the crank by hand, and still couldn't find anything. my 84 had a line going across the pulley. Any other way to find TDC on the balancer?

I would get under your truck with a very bright flashlight and a fine wire brush...sometimes they are covered in surface rusta nd it looks like nothing is there...if you still cannot find it try this:::
there is a way to manually find TDC...pull your #1 spark plug, then with a screwdirver or something similar (don't drop it in) feel around to see if you can find the piston; by hand turn the crank slowly until piston #1 is at the top of the cylinder....make your mark for future reference. I do believe that this is a rough way and would need fine tuning but it will get you started.
