Well. I am doing a tune up on a 98 Camaro with a 3.8L. Not the easiest at all.
Which got me thinking.
Whats the worst set of plugs you’ve ever had to or have done?
ATM I am gonna have to say this Camaro.
Motor is pushed sooooo far back in the fire walls on these cars. Spark plugs are under the exhaust manifolds. Starter is partially in the way on bank 1. A/C is completely in the way on bank 2.
I know the Northstar motors in some of the Caddies are a bitch to do bank 2.
2.5L ranger - 4 banger but has 8 spark plugs. 5 are easy to take out (relatively), 3 on drivers side near firewall are a bitch. I figured it would be easier to take them out without removing the IM.
When the plugs had been in there for ~150,xxx km, shit was seized. Snapped plug boots 3 out of 3, had some crazy ratchet setup - extension, universal, extension, universal, stubby extension, socket - to remove the one.
