Hi, you should double check your spark plug leads are on the correct cylinders.
Trace each one all the way from plug to dist cap to make sure.

oh i snaped one and got a new one from the weckers its the same size but isa mits one and mine are all bosh can this do it?

No, the brand should not matter.
Whilst it is always a good idea to have a matched set of leads, we all know that they don't break when convenient.
It does sound like the leads are possibly on the wrong cylinders.

ok its sounds like some one tapping a pen on there teeth is there a chance its gone in to the engine ?

make a recording and post it up. it willmake it easier to diagnose.

allright il do it tomorrow

If you have had rocker covers off and you now have a knock, you have dropped something in there, no plug lead will make a knock

You also mention you dropped a bolt somewhere, you need to locate where you dropped it and retreive it, find if the knock is coming from the front or rear bank, determine which cyl is not firing and then determine from there what is going on

its from the rear one will it still be in the rocker cover part?
i replace the bolt with a new one any ideas how to find it?

so you just left the bolt INSIDE the engine...:kb:

have fun mate...

i would honestly not start the car until you have this sorted out.... because bolts can cause ALOT of damage inside engines...

Have you been able to find the bolt yet?

no thats if there is one,sending it in to the shop tomorow

iv been told buy the shop that it sounds like a bolt on top of the piston

So it is sounding like that missing bolt may have fallen down inside the manifold then...hmmmm...this is a good reason why I always state that it is not always a good idea to try DIY as it can end up costing you much more in the end.

IF this is the case, then you are far better off just getting a low k engine installed

mine is low km well 160000 lucky iv got some mates that are gonna fix it up hopefully looking at around $1000. FML

If you can find someone with a scope, they can actually look inside the cyl to see if there has been any damage to the piston and to the bore. If there is any damage at all, even to the head, I highly doubt you will fix for a grand even if you are not paying labour

Granted you have a low K motor, what model is your car, if is a H or earlier you are still far better off getting a low k motor from a TJ or later as then you also get the better cam shafts, you should be able to pick up a good motor for under 1k thus even with fluids you will be fine. You do not need to take out the trans either BTW

Also, if you do still persist with this engine, make sure you use GENUINE head gaskets as these are by far the best ones to use

shit happens, thats what im finding out tomorrow how much its done might have to cut my lose and take what i can

So how did this turn out?

haveint found out yet cuz for the prodyno comp going on at there shop

Pro tip, if you are going to do rocker covers, cover the lower intake manifold with an old rag so nothing gets inside... Works for me :)

i did thats why i dont know how it happend
