LOL! My 89 cavalier z24 did the same thing, it had 6 cyl though. Shortly after that the exhaust pipe broke off just behind the cat. I thought the engine had exploded! That biotch was loud for a 2.8L v6.

 

would HT0's w/out NOS or F/I cause excess build up? is it a bad idea, or does it make no difference?

 

for a 9/16 socket, do you need a special deep one to get at the plug?

 

Yeah give us more tips on this... Im at 10K miles and about to do it... Nervous.

 

Well my V6 coil pack went bad and I was drivin on 4 cylinders to get home....talk about a shakey ride.....

 

It needs to be deepwell, but nothing special. They are probably the easiest plugs to remove i've ever done, except for removing the coil packs.

I'll post more later about how to do it and what else will make it easy.

 

lmao, r u kidding me lol? try 153K..... talk about rolling once u have over 100k, rolled over 10 k, listen to this guy lol

 

Well this new spark plug design has been known to seize in the head and break off the heat shield. If you'd go 153k miles without checking your spark plugs I feel sorry for your engine.

 

Exactly... The guy above must not be informed on the problems.

These plugs are known to have some sort of sheild or something weld itself on there, so the plug can EASILY break when being removed and then you got problems... The sooner you can check them and put anti-seize on then do it.

 

ahhh i c what your saying, i didnt know about that problem
