Well I finally checked the hot lash this afternoon and Newbomb Turk is correct - there is slightly more lash hot than cold on my iron block, iron heads engine. I set them .016" cold thinking I'd get to 0.014" hot, but they are at .018.
Now I have to fix them all, I'll set them to .012.
Another question - when I removed the plugs a few look dodgy - especially drivers side, nearest firewall (labelled Drivers Side No. 4) These are new plugs - I changed them a few weeks back when I did the lash the first time. That plug that came out from that same location looked similar then too, with the central electrode looking burned up/lumpy deposits on it.
The plugs I had in it were NGK BP5S and I went one colder to a BP6S.
I've probably driven the car about 8 times on these plugs, with two long 120 mile highway trips on Saturday and today.
Any ideas what's going on there?
