What kind of reliability is had with the factory plugs? I'm sure it's spectacular when they fail, but is it really that often? Is replacing them with threaded plugs just going to let me sleep better or is there more to it?
Any response is appreciated. Thanks, Joe |

QUOTE how many different types of aluminum are you aware of? As far as I know there is only one "type" of aluminum. It is... aluminum. I am aware of quite a few different alloys. And yes, I know that the case is cast of A356 and that the plugs are likely stamped from sheet aluminum, probably alloy 3003. |

I was trying to answer his initial post... How reliable...well its two different alloy blends (actually two different process's) that have been trying to hang on to each other for 40 years and countless heat cycles. Similar issue with valve seats. They are both a tight fit that relies upon friction only...and two different metals expand and contract at two different rates. Two different alloys of aluminum expand and contract at different rates also. For me, It is so cheap and easy to do, I just tap them all and replace them. Seems kinda crazy not to do it. From what I have heard and seen its not super frequent that it happens...maybe ten that I know in the past ten years....so its not alot. But, its your motor..and your risk. would I pull a motor just to replace them, no. Would I do it while I am rebuilding a motor, absolutely. rich |
