Crap

[chevychic]

Just when I thought I had all the little miscellaneous problems fixed, another pops up. I was really hoping to start spending some time on the interior but that's going to have to wait....again.

Going down the freeway Monday, it started vibrating really bad so I pull off in a little town to find that the vibration is actually a really bad miss. Found a plug wire with some burn marks from being too close to the headers (my looms suck). So I got new plug wires. Well it happens again Wednesday but even worse. Pull off the freeway and take it to another little shop. Mechanic does a compression test on #8 cylinder and it's not firing.
So he suggests adjusting the valves and quoted me 9 hours at $52 an hour. I don't think so!
So I have another problem to tackle that I would really like to tackle myself and save my $$ for other truck stuff.
I've been reading some stuff online and doing some searches, talking to people and it seems like something I could do.

But I would just like some reinforcement, get some tips and hints from the pros on here.
Is there anything I need to be looking for specifically while I'm in there? It seems weird that this happened so suddenly, so I'm almost expecting to have to replace some parts. Maybe this'll be my chance to get new lifters and cam???
I already got some good advice from Tom and Jeremy (thanks guys ) but would like hear more.

I did read up on Swervin's site too. Pretty good information there and I printed it out to use when I dive into it this weekend.

Any advice would be very appreciated
