Changing spark plugs & leads, probs rotating engine

[mikesmith20001]

Hello All,

I am planning to replace spark plugs & leads on my 2001 Buick Regal with the 3.8 s2 v6. Is this soemthing do'able for a diy mechanic???

Could someone please give me some advice, i'm having problems getting to the rear spark plugs.

From what i have read i need to "rotate" the engine. To do this i unscrew the strut bolts and bring the engine forward, but any idea how to secure it in place as i change the spark plugs and leads ???

Could someone please highlight the exact steps required to change spark plugs and leads.

I am refusing to take it to mechanics even the dealer as they simply do not do a good job but happy to take loads of cash. Its got to the point where i know i can do it better and won't go around scratching the paint or sitting in it with oily overalls. Have done lots of work on previous cars, but none were as complicated as my Regal.

Thanks in advance.

It is not necessary to tilt the engine forward and is more trouble for what it is worth. It won't give you that much more clearance. Also, you run the risk of damaging the transmission mount. Getting it back into position will be a PITA. Plus after the job gets done you may have more noises than you can deal with like creaking and thumping sounds.

The key is to have the right spark plug removal tools and patience. Another thing that might help would be to remove the 02 sensor from the exhaust downpipe and the bracket that holds the 02 sensor harness which is mounted to the exhaust manifold. The hardest part is getting the metal shields and spark plug boots off the rear plugs.

I've never titled the engine in any my Regals but got the job done. During wire installation make sure you use hi-temp silicone grease on the plug boots so the metal shields come off easier next time around.

Ahha - just bought one of these last month and never thought to check access to the plugs (oil filter is a breeze).
bnaylor: what would you consider being the "right spark plug removal tools"?
I might as well get them early before the Christmas rush

Here a pic of what I use. The ratchet is made specifically for spark plug removal.



You can get ready made kits with these tools at any popular auto parts store, Sears, Snap-on, etc.

Also, I have the special socket to remove the 02 sensor in the way which has a slot for the 02 sensor wiring harness. When I replace plugs I clean the 02 sensor as a preventive measure all at the same time.

Thanks bnaylor
And I wasn't kidding about Christmas - wife asked me what I wanted this week and I'm going to print out this photo and tell her to "hit the streets"
Thanks again
