I have finals coming up this next week. Bah..... How long will it take to change out the plugs and wires? I'll be running MSD SC 8.5mm and NGK TR55s, prolly the Iridium despite their excessive cost!!!

 

First timer, all day and more.I'm not kidding here.Most frustration with the plug wires putting them into the looms.And don't over tighten the plugs in the aluminum heads(always do this when the engine cold.My02.

 

How about time-wise without putting them in the looms? Also, am I going to have to take any components off the engine to get these plugs in? I don't know a whole lot about the LT1 setup in particular, so I'm bracing for the worst.

 

Just as long as they don't touch anything(metal),They won't short out.Do you have all the proper tools recommended by this board?

 

First time with manifolds? ~6-10 hours IMO. I can't help you with what you'll need to take off as my plugs/wires were done shortly before I bought the car and I replaced the plugs during a header swap.

 

Yeah, first time on this engine, at least. I have all the tools necessary, I believe. I have a fairly extensive set of tools for engine work, so here's hoping. Was there anything special or out of the ordinary I need from this particular plug and wire change?

I plan on leaving the manifolds on, but does anyone else know if I need to take anything else off, or will I be able to get to it all without having to remove stuff? This is my primary concern above all else right now. Thanks!

 

Alternator and power steering pump came off of mine. #2 plug access and the wire routing made it impossible for me to do unless they came off. Start to finish for me was around 6 hours. My situation made worse with the headers.

 

I've never done both at the same time, but together it would take hours. I didn't have to take anything off to remove or replace anything. Luckily for me my skinny arms allowed me access to everything.

It's a pain one way or another, start early in the day and just take your time.

 

Alright, good to know. I love these engines, but I'm just saying that whoever designed the frickin things was a retard.... :-/

 

Do you have anti-sieze compound?

 

I'm thinking PB Blast. Are they sometimes really hard to get off?

 

Its not for taking them out. You put a tiny dab of anti-seize on the plug threads, before you screw the plug into the aluminum head. That way they come out easier the next time.

 

Okay, gotcha. Yeah I was kinda wondering for a second. Yeah I will make sure to do that, don't worry.

Do you have a suggestion on a brand of anti-seize?

 

Permatex 133AR in a small tube.

 

Thanks! I'll pick up some.
