Changing spark plugs, Chevy Blazer
I've finally gotten around to changing the park plugs on my Chevy blazer, vintage 2000. Or trying to, 5 done, 1 to go. It's the one though that begs the question, are all automotive engineers on crack? :~
They are platinum spark plugs, supposedly good for 100,000 miles, I thought seven years and 90,000 was close enough. I've always known they were hard to change, thats why they use such high mileage spark plugs I suppose. But dang, close quarters is one thing, removing components just to change the spark plugs is another. It appears one has to remove the steering shaft to get to the fifth spark plug. :? I've tried a ratchet, a breaker bar, a gear wrench with socket adapter, I've tried putting the spark plug socket on as far on as it will go and then trying to get the ratchet/breaker bar/gear wrench on, nada, nope, not going to happen, just not quite enough room. I figured if I could even just get it on there and break it loose I could back it out with my fingers but its too tight to even get anything on it to break it loose with.
.5" up or down or .25" further away and this problem could have been averted, but no, couldn't do that.
Why? Why? Why?
Why do they mix metric and standard fittings? Thats another good question.
Why do engineers have such issues? :~
