Ok I got everything done the other night... After cam rockers,pushrods and hooker lts

when I put the opti back on the first time I pulled it it wasnt keyed in..

When I tried starting it blew fireballs out of a unplugged vacume line and the Throttle body

I took everything back apart and Fixed it untill the opti slid right on

This Time When I go to start it turns over its getting gas.. And it Blows a fireball out of the passanger side header? and funny noise like your blowing on a glass bottle.. I think its the flame traveling back up the header..

Need help... Bad Timming ? Installed the Cam wrong? Crank sensor?

TrouserSnake

Think It could be the lash Is way off?

Double check your plug wires to see if they're in the right spots. If they are, then it's most likely your rockers. (too tight)

TrouserSnake

would this cause a fireball ? (the lash)

Im thinking its the timing...

madwolf

Don't know about a fireball but it will cause it to backfire, yes.

TrouserSnake

Went over my work again... One Rocker was extremly tight I loosed it same thing.. Same type of back fire.. And I can hear the Fire Traveling back up the header to get the un burnt fuel

You don't have your intake elbow on, correct? That's the whistling you probably are hearing.

TrouserSnake

its after im done cranking the car over... (when the woof/whistle happens)

like Ill here a ignition of gas then its burning all the unburnt fuel down the header tube it sounds like..

At least its not blowing fire out of the Thottlebody anymore

(I didnt have the opti keyed in the first time)

Now I dont know whats going on

kandied91z

this doesn't help but i had bad programming and timing off which caused the exact same thing on my car....

TrouserSnake

Could I have screwed up the Opti? when I pulled it on not in key?

TrouserSnake

Id like to start the car today... Should I go get a new opti?

Would any vacuum lines cause something weird

Any sensors I could have missed? Crank sensor? anything?

Its so depressing Ive had this thing apart twice... I mean what now throw it away?

joeSS97

How did you adjust the rockers?Make sure everything is plugged in.Did you double check the timing dots?

Crank sensors werent put on our cars until 96.
