PostSubject: Only took me a year and a half to figure out why my car ran like A##   Sat May 12, 2012 11:25 pm

Those who know my car know how much time and money i put into it in the summer of 2010.
It never has run right .
Well after trying damn near everything on the engine / plugs / wires optis= 3 times / intake gaskets = at least 3 times / sensors / etc.
I pulled the manifold/valve covers last week and found affraid


Old bent and burnt valve beside new exhaust valve !!!!!


4 part spring bent pushrod and chewed up rocker.


Closeup of rocker.


Nicked piston top.



I beleive what happened is I had a set of mid 80s magnesium valve covers that i installed without clearincing the inside enough for the roller rockers.
When i started the engine the rockers hit in a couple of spots .Cracking the valve cover.
I didn't realize it at the time but it must have damaged the front most exhaust valve/spring.
Eventually the spring broke / pushrod bent and lifter came apart fortunetly no parts fell into the lower end and I'm in the process of putting a new set of heads on. Hopefully i'll be back on the road soon.

Took the other head off and removed and installed all the springs on the new heads tonite.
Suggestion for anyone doing springs
Get a spring remover/installer that you can at least put a rachet on.
Mine has a star handle and after turning by hand it 30 plus times . Never again Rolling Eyes
What"s the story on these sguare plugs in the head Does it take a specific Wrench/driver ?????
I needed to remove this one to install the temp sensor.
It looks like it should take a 3/8 rachet but it's too small.
I ended up grinding down an old extension to get it out.


Couple of random pics.I need to work on my photo skills LOL.


THE GOLDEN WRENCH Nothing but the best for the Beast.!!!!!!! .

Your going to be SO HAPPY running on all 8 again.
It is a PIA working the heads in the car but sounds like your all over it.
Keep those progress posts coming... Arrow

Yea It was definitely easier working on the engine with the front clip off.

The one plus is everything is new so it came apart fairly easy.

The SLP headers are probably not going back on = Too much stuff in the way to get them bolted back in .

Well i got it back together and running.
Thought you guys might like to see a couple of random pics.
Almost forgot to put these plugs in the new heads.
Would have been a nice mess.
By the way these took a small rachet head unlike the one for the temps sensor i showed earlier in this thread

Heads installed valves adjusted.

The exhaust manifolds i'm using looked like A## and i had a can of engine enamel kicking around.
Decided to try painting them They looked great when i put them on BUT the paint is slowly cooking itself off Rolling Eyes

The finished product .

Waiting on one replacement spring will be firing her up tommorrow.

The SLPs were a b#tch to get off.and would be even harder to get back on.
When i originally installed them the front clip was off.
and i never liked the plug access with them.
So they may get reinstalled later or get sold. I could really use the money.
