I've read a lot of posts about the VVT and variator etc. I know this is part of the 16 valve engines, BUT, do the 8 valve engines have VVT ???
From what I gather, they don't !!!

From what I know (not a lot!) its only the 16 valvers that have variable valve timing but think its different to the Honda set up.......is this correct?

Hi Marlon ,if you look at the front of the engine there is a timing variator if that is the thing you mean then yes they do have it,8v 75`s had it as well,it is a barrel shape device with two wires on it.Alfapat

Cheers pat, i'll have a look for it. Maybe it isn't working properly as my car has a terrible flat spot at low revs, then flies from 3500rpm.

hi marlon the cam variator is on the end of the camshaft and can be seen only when you take the rocker cover off the post before i think is relating to the variable valve timming solonoid this is what i have on my 16 valve, its just at the back of engine and have read on net to try melting the solder on the top (2 round bits ) and then you can remove the screws and clean contacs inside but itried this and it did nothing for me hope this helps rather than confuse fletch.

Thanks Fletch

I've started using Super Unleaded petrol and that seems to have helped the flat spot problem a lot. Checked the spark plugs tonight and found the cables had splits/melts etc. Need replaced. Incidently, all the plugs were the same size. I thought one set was smaller than the other ???
They are NGK 3 prong doodas and look in good nick (at least I know the engine and fueling are fine)

Hi
I should check your plugs again. 1 set is definitely smaller(thinner) on my 2.0 16v

You should definately have two sizes of plugs?

10mm and about 14mm(?)

Perhaps its a cut'n'shut engine with identical halves wink

Hi Marlon

Just realised, yours is an 8v, are the plugs all the same on them?? Dunno, as Mike sez, my old twinny 16v had two different sized plugs.

Hi Wrinx
Yeah, I have an 8 valve and all the plugs are the same size and grade.

That means my plug replacement costs won't be as much as you 16 valve guys :D
My plugs are standard things.

Great
