How tight to set solid lifters

66 Sat said
Yes as per post #13.
I used blue loctite on the loose one. I just finished re-checking the cold setting. They are still at .016" and the loose one has stayed at .016" which is good.
I'm not looking forward to checking the hot measurement at all. Apart from the heat issue, if they have loosened further and the advice I followed is backward, then I'll have to do them all again...
Fingers crossed 66fs is right and Newbomb Turk is wrong (no offence of course, it will just save me an hour or so).

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?
