i changed my valvecover gasket and now the car is messed up - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

civilized_drifter · 04-14-2007, 02:55 PM

so i took the valve cover off my sohc and replaced the gasket tightend(spelling) everything down and started the car and it started shakeing really bad and it sounds like the timing is off, i didnt touch the cam, timing chain, or anything, the sparkplug wires have a good conection and i have no idea what could be wrong

motonagam · 04-14-2007, 08:28 PM

did you remember to reconnect vacuum lines that you may have disconnected, or accidently knocked off?

InspireMS · 04-14-2007, 08:32 PM

did you torque everything back together accordingly to the factory specifications?

viperbite · 04-14-2007, 08:35 PM

shakin...
thats really weird...
hmm
i really dont know what it could be
double check to make sure you put the wires in the right holes for the spark plugs...

jkjunior · 04-14-2007, 08:39 PM

ya def could be a losse plug wire or like viperbite said in the wrong holes

Dutchmalmiss · 04-14-2007, 09:31 PM

+1 for plug wires and vacuum lines

civilized_drifter · 04-14-2007, 10:16 PM

all spark plug wires are in correctly, the hose that goes from the valve cover to the intake manifold was cracked so i duck taped it and it was still doing it. i didn't pull any vacuum lines out,could there be any on the back that i cant see that could cause this?

twofortyrida1388 · 04-14-2007, 10:33 PM

Sure you didn't drop anything inside. If you did cams could be eatin it up and preventing them to do their proper job causing some intake and exhaust timing problems.

civilized_drifter · 04-15-2007, 11:18 AM

im shure i didnt drop anything onto the cams

HIGHMILEHATCH · 04-15-2007, 12:24 PM

If it's shaking like you say, thats typically only running on less than all four cylinders. You probably don't have one of the plug wires in the right order, or it's just not on at all.

chmercer · 04-15-2007, 01:06 PM

im guessing the center vc gasket is messed up or installed wrong and 1 or more spark plug holes are filled with motor oil

this is also very very possible
maybe damaged when removed?
if you remove it too fast then it could do that

civilized_drifter · 04-15-2007, 07:23 PM

i didnt unplug any sparkplug wires and tomarro im goin to the junkyard to get that hose peice, when i get home from school i'll check the sparkplugs and replace them if needed. if it is still doing it im gonna bring it up to nissan where my friend works and he can figure it out, if he cant fix it it wi'll be time to finally swap to a ka24de. i'll check back tomarro on what happens

viperbite- it took a while to take the valve cover off cause it got hooked on to some wires

civilized_drifter - yah i meant like if you pulled on it real quik or something... or used a screw driver to pop it off
i dunno man have your friend check it out... i dont think its that intake hose cuz you can leave that off and nothing will happen lol cept some dirt in the chamber

driftenthusiast · 04-15-2007, 08:06 PM

just pull wires and see with cylinder isnt running, then see if that one has spark.

civilized_drifter · 04-15-2007, 09:14 PM

it really doesnt matter
you can put a breather filter on that hose and it would be fine...
i dont think thats the issue ...

civilized_drifter · 04-15-2007, 10:14 PM

ya, i just wasnt expecting that thing to pull out when i did it

chmercer · 04-15-2007, 10:50 PM

no it dosent matter

if you really want you can like jb weld it back in or something

LB.Motoring · 04-15-2007, 11:15 PM
