Changing Spark Plugs.

hussarman · 13-05-2008, 17:28

For what it's worth.
Today I watched a professional change four spark plugs on a Octavia 2003 1.6 Petrol engine.
Absolutely amazing, job completed in seventeen minuets, to me it seemed tantamount to climbing Everest.

It's a pretty easy job once you've done it once.

Whip coil connectors off
Whip coil packs out
Take out old spark plugs
Whack the new ones in (hand tight, then with a torque wrench)
Put coil packs back in
Reconnect.

If I can do it, anyone can....

Obviously you havent seen a 1.6 (or 2.0 near enough the same) engine then...lol.

Plugs are buried under the inlet manifold which wraps over the cylinder head. 2+3 are a pain, its a knack to change them.

Sounds gay

Getting the plug leads off intact is also a skill with these engines.

Roker · 13-05-2008, 21:13

While we on the subject. Should ther be a cover about 50 mm x 150mm over the coils?
I think mine is missing, I can see the connection when I lift the bonnet
1.4 petrol

16v I guess then, depends on which engine and year.

hussarman · 13-05-2008, 22:08

Messrs Lummox and Fordfan have got it right. No. 2 & 3 plugs buried under the inlet maifold, the mechanic did mention take extreme care with the HT leads which are prone to become brittle and break.

KenONeill · 14-05-2008, 12:50

Yeah, I was thinking "how hard is moving the coil packs on that engine?", cos I've changed plugs on a double-ended coil engine faster than that (and even checked the gaps were right when doing it).

Spark plugs? I've forgotten what they look like!

From what I can gather, the Vauxhall 3-litre V6 is a pain to do them on Cavaliers and Vectra's as you have to remove the inlet manifold from one of the cylinder banks to get to the plugs.

You're so right about that.

Yup, my old V6....

Sounds like the punto I did them on last week.

sparks at back on engine under the inlet manifold and the single point injector with the throttle wire running over them and breather pipes all in the way too.

That plus the air cleaner needing to come off too so even see that lot.

2 was a real PITA.

Why people don't think about this when designing engines etc I'll never know.
