I'm sure there's a how-to on here but I did several searches and didn't find it. I'm replacing the plugs and wires on my 3.4L and the ones on the firewall side look very difficult to get to. What's the best way to get to them?
I think with 132K on the original plugs and wires it's about time to replace them Very Happy

I don't know if the 3400 has the same engine mount system as the 3800.

On the 3800 there are two large bolts in the dogbones that you can remove. This allows you to tip the engine forward. There is a second notch/hole in one of the dogbones/mounts that allows you to pass the bolt through while the engine is tipped forward. This gets you some extra working room. The plugs will be difficult to remove because of the rubber insulators and the aluminum shields. Just keep at it and eventually they'll work loose.

Of course, the 3400 may not be the same. but I bet the plugs will be close to, if not just as difficult to remove - especially given their age.

If I recall right, there may have been some suggestions to try removing them from below. I'm not sure how this would work since they are angled upwards, and I never tried it when I changed my plugs and wires.

In my knowledge, there's never been a how-to on the process, since it's pretty straightforward. The only catch is that removing the plugs/wires is easier said than done (mainly in the rear bank of cylinders)

The 3400 isn't that hard to work on, I usually secure the engine forward with some mechanic's wire (aka coat hanger) because it takes way too long to bother with that extra bolt hole that isn't always there. Then I spend the rest of the day yelling about how much I hate working on domestics and pop a Heiney cause I'm a douchebag.

I hear if you tip the engine too far you can f#ck up the trans lines but I've never seen a problem. Just relax and it'll go fine. You don't need to go all He-Man on the plugs btw, spec is like 18 ft-lbs or just about good and snug.

Make sure you have a few extensions of various lengths and at least one universal joint. I had to get creative when I did mine on the Monte Carlo (3800 engine) but they both suck.

simple, get a foam pad to place on top of the engine for cushioning, remove the coil and hoist your big arse on top of the motor and get them from right on top. best way I've found yet, it's a little more intensive but easier than trying to tilt the motor forward, barely helps if any.

Thanks, are there only the two bolts in front holding the coil bracket?

yes, be sure to disconnect all the plugs going into it, hate to hear that you pull up on the coil only to snap stuff.

Exactly what I did when doing my head gasket job.
I would suggest to remove and replace each wire one at a time. That way, you can match each wire to proper length and run it neatly.

Sounds good, thanks for the tips. Hopefully I don't have to mess with tilting the engine. I got up on the engine last night and I can at least get my hand on every plug wire without removing the coil, so once I remove it I should be able to get the job done. Thanks guys! Impala

my 2 cents 2 Cents

Tilting the motor is very little effort and it does give enough room that Universal joints are not needed for the back plugs on a 3.4.
