N/A Spark plug replacement


JS2004

Recommended Posts

Hola!

 

I am going to replace spark plugs tomorrow. I have had the cam cover off and the spark plug cover off to get at the coil packs, but it seems that the manifold is in the way and there would be no way to get at least two of them out without removing the manifold?

 

Is there anything I need to take into special consideration when doing this? Its an N/A.

 

My plan is to replace the plugs with ones from Alex's spark plug Faq, and whilst im at it im going to replace the coil packs (This is an effort to stop the misfire that im currently experiencing).

 

I have had a look around to try and find a guide / info on this but most of the advice and write ups are for TT engines - which is a bit different :)

 

Cheers!

I was looking at the airbox pipe and wondering if I could take that off - its all stock in there.

 

I spotted two bolts under the maifold looking at it head on and figured they might come into it. Im going to be playing it safe and taking pics of stuff after removing each part.

When you say "replace the coil packs" do you mean the HT leads? NA's don't have coil packs. They have a dizzy on the exhaust side of the cylinder head,

 

After about 120,000 miles I went to change my spark plugs and but the tops of the HT leads came off in my hand when I tried to pull them out. Apart from having to get a new set of those it wasn't a difficult job. You don't have to take as much apart as it looks.

I got my leads from Keron that set me back £30 delivered. New from Mr T were 100+

 

Digsy, its the leads that go into the spark plugs yes =) I was told by Mr T that they were the same part for TT and N/A but Keron told me different, so im not sure of the official name right now, but its them cables :)

 

They feed right under the manifold which is the bit I was worrying about.

*gulp* this doesnt look like its a fun job LOL :) why did they put that manifold over the engine like that *tut*. The good thing is that I can use this as my argument when im trying to justify a TT purchase (grin) :)

 

After all this messing it better sort out my misfire lol :)

 

Edit - the more I read this and look at those documents and pictures.. the easier it seems :)

Which plugs would they be DNK? I went with platinum ones came to £53 delivered for 6. After searching on here though there was a website that was selling the Denso PK16R11 for 6.6 each (before VAT).

 

Im fairly sure Keron said he had two sets of leads available when I spoke to him last week though Nevins - I would give him a call if your not too fussed about getting second hand ones (although theyre still going to be roughly 15 yrs old).

Christ, I don't recall my HT leads from Toyota being over £100! I'll go and dig out the reciept.

 

Get the proper Toyota ones. They even come all pre cipped and arranged. All you have to do is lay them in the valley and push them home, then bolt down the clips. FWIW I'd get the standard Toyota plugs too. £6 / £7 eacj isnt bad considering how long they last.

 

Incidentally, I guess that Toyota used platinum tipped plugs on the NA because changing them isn't a five minute job, so it would help keep regular service (labour) costs down.
