ive just got round to getting the rocker cover gaskets, plugs and cambelt kit fitted  
i bought genuine GM parts and got a mate to fit them (15 years ex vauxhall mechanic) at a small cost of £150 
he said the gaskets were like plastic and the plugs and leads were totally submerged in oil but it still ran smooth  
but now i have a problem, now its dry its got a missfire from tickover to 2500rpm  

are the HT leads knackered now :question

[Martin_1962]

Possibly - or an air leak

[V6drift]

it wont even run now when its hot  
runs not too bad when cold but as it gets hot its not on 6  :-/
how could it have been right before the rocker, plugs and cambelt job but not anymore  :question
if i get some new ht leads to try what sort of job is it to change them  :question

please help as its starting to p--- me off already  

[albitz]

it could also be the dis pack (or both) it is awkward to change the leads but not technically difficult in any way.im sure there are guides / photos etc on the site which will assist. .........if its running worse after being worked on you might want to check,have the plug leads been put back in the correct order,have the correct type of plugs been used and has the cambelt definetely been fitted correctly.

it ran perfect before the work,
i had it worked on by an ex vauxhall mechanic so it should have been done right,
the only difference is the spark plug ports were full of oil and now they are dry,
also on one of the ht leads, some of the rubber shield on the plug end is missing,
any ideas?

You are to trusting.....

Does it miss fire at all on tick over?

[V6drift]

yes it is missing on tickover,
to start with it was on tickover and upto 2k but only when it was hot,
now its missing on tickover and all the way through the revs all of the time...

can't you ask your mate who was a vx mechanic for 15 yrs?

Sounds like hes connected the plug leads on the dis pack for the 2-4-6 bank up wrong.

If he has, dont run it or you could hole a piston.

[V6drift]

well its sorted (more bodged to be honest)
but at least its confirmed that a ht lead is faulty,
i,ll get some bought asap...

[Marks DTM Calib]

Dont buy genuine, get some Bosch ones...

[V6drift]

thanks for the advice,
ive seen bosch ones on an ebay shop for £39.95,
does that sound resonable???
