YenkoChevelle69 Posted December 15, 2007 Report Share Posted December 15, 2007 Never dealt with aluminum heads before. Always cast iron big block chevy, small block etc. I know that antisieze is used in order to keep the threads from seizing or galling when it comes to aluminum. I know that the plugs are 100K mile plugs, but I want to do plugs and wires as preventative maintenance. I haven't actually gone out there and put a wrench on these plugs yet, BUT my question is..... Am I going to have a headache getting these things out? Assuming they are factory plugs and have 80K on them. That's a long time to get stuck. Are there any tricks or tips I need to know? I assume I should get the engine up to operating temp, throw on some gloves and try to remove the plugs while the metal is still good and warm. I have intentions of using AC delco plug 41-985 MSD Wires 32829 antisieze when reinstalling them. Thanks! Quote Link to comment Share on other sites More sharing options...
desrtrat Posted December 15, 2007 Report Share Posted December 15, 2007 also put some dielectric grease in the boots, coil and plug. will make life easier the next time you pull them off. don't need a lot, just a lite coat on the inside. i use to put a small bead inside and roll the boot between my fingers and that will spread it around nicely...

KJT13 Posted December 15, 2007 Report Share Posted December 15, 2007 I did mine at 75K. The only issue you will have is the #8 cylinder. A 1" extension made it alot easier. A 3" was too long and with no extension it wouldn't reach. Also, with the MSD wires, you're gonna have to rotate the wire closest to the steering shaft bolt so it doesn't snag. (I think it was the #5 cylinder) and next to the #8 you need to bend the heat shield under the a/c compressor so it doesn't rub the wire. All in all, an easy job!

You shouldn't have a problem getting the plugs out, you might need a little elbow grease thats all. Like keith said, rotate the #5 plug wire counterclockwise at the coil boot a little to avoid contact with the steering shaft bolt. Doing so takes the slack out of the wire. Make sure to bend the heatshield for the AC condensor lines about 1/4 inch towards the fire wall to avoid chaffing of the #8 wire over time.

Quik Posted December 15, 2007 Report Share Posted December 15, 2007 maybe consider a NGK TR5 spark plug. Quote Link to comment Share on other sites More sharing options...

YenkoChevelle69 Posted December 21, 2007 Author Report Share Posted December 21, 2007 is an NGK TR55 the same? Is there a difference between these and the delcos? Quote Link to comment Share on other sites More sharing options...
nova72 Posted December 21, 2007 Report Share Posted December 21, 2007 not sure about the plugs but I didn't notice if anybody said about taking them out. If the heads are aluminum I highly suggest not to get it up to operating temp. because when you take the plugs out the threads are going to be expanded and if you try to put a new plug it it could actually strip the whole Quote Link to comment Share on other sites More sharing options...
Jond983 Posted December 22, 2007 Report Share Posted December 22, 2007 is an NGK TR55 the same?

Champion201 Posted December 22, 2007 Report Share Posted December 22, 2007 From what everyone has told me, unless you have a blower dont go with the NGK TR6 because they are a colder plug Quote Link to comment Share on other sites More sharing options...

KJT13 Posted December 27, 2007 Report Share Posted December 27, 2007 I've heard the same about the TR6's. I went with the TR55. Quote Link to comment Share on other sites More sharing options...
YenkoChevelle69 Posted December 31, 2007 Author Report Share Posted December 31, 2007 I've heard the same about the TR6's. I went with the TR55. Well, I picked up 8 NGK TR55 plugs and I have the final plug wire coming. I guess in the next week or so, I'll be changing plugs! 55 gap right?
