i already changed the fuel pump a couple month's ago but when i changed the oil today it still smelled like gas.even the cap on the valve cover smelled like gas.the reason i changed the fuel pump was the gas in the tank was old and i wanted to burn some fresh gas,so i filled a coffee can and stuck the pickup line from the tank in the can and it sucked it dry in seconds.so i figured the seal was blown in the pump. BUT it's still doing it. what else could cause it??? /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
Hey, boggerless is a NEWBIE /forums/images/graemlins/histerical.gif /forums/images/graemlins/histerical.gif /forums/images/graemlins/histerical.gif /forums/images/graemlins/histerical.gif
 
maybe i should have said it was a new crate engine. /forums/images/graemlins/blush.gif it's a 350. i know that doesn;t rule out the rings but . /forums/images/graemlins/grin.gif /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
quit making fun of me you big meeeny. /forums/images/graemlins/rotfl.gif it has a carter afb on it. (oh and by the way i have two dip sticks now). /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
i'm assuming your using a mechanical pump. i'm preaty sure that there is a return line coming off the pump did you have this line routed into the can aswell /forums/images/graemlins/dunno.gif /forums/images/graemlins/thinking.gif if you did't your fuel is all over the ground and it probably wouldn't take long to pump all the gas out /forums/images/graemlins/yikes.gif

as for the gas in the oil have you been flooding the motor alot? if it's a brand new motor that hasen't been running or broke in the rings might not be seated yet and if you have been flooding it trying to get it running there's a chance the gas could squeeze by the rings /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif
maby that'll help /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif /forums/images/graemlins/peace.gif /forums/images/graemlins/peace.gif
 
i think your right,the engine has about 6 real miles on it.and the timing was of so i used gas to get it to start.it's turn key now ,but untill i found out the rotor was pointing at the #1 piston and not #1 on the cap,i was hard to start.(so the other pump might still be good /forums/images/graemlins/grin.gif). thanks /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
keep the other pump as a spare, you'll need it /forums/images/graemlins/waytogo.gif

i was working on a buddies truck, changed the oil 2 days before, ran great, had great oil pressure. put a remaned edelbrock 750 carb on it, it ran like crap, spewed gas out the exaust, checked the oil was 1 quart down and was very gassy (cam2). pulled the carb and it was just dumping the gas down into the motor. put the old carb back on and left it. /forums/images/graemlins/thinking.gif /forums/images/graemlins/thinking.gif

is it running rich? /forums/images/graemlins/dunno.gif
 
Me no meany. Me just tryin to hep. /forums/images/graemlins/1zhelp.gif

But, I think the goodly amounts of gas bein applied coupled with the brand spankin new motor is prolly the culprit as well.

Change the oil and keep an eye/nose on it and see what develops. /forums/images/graemlins/thumb.gif
 
WHAT'S UP TJ? yea,it has been running a little rich,so i pulled off the air cleaner to mess with the air/fuel screws and i found the choke half closed(it's manual). the cable is loose as hell.if the carb was dumping wouldn't it flood or kill the engine??? it idles pretty smooth. /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
i know your justhorsinaround(YUK YUK). like tj said i was a little worried about dumping,the carb came from a friend that seems to have that problem. /forums/images/graemlins/eek.gif /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
my friends would idle fine but when full throtle, it was alot of black smoke from the exhaust, plus liquidy film in the pipe that smelled like cam 2
 
my dad gave me two Q jets,so i'll get one of those going. i have never floored it so... /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
 
My vote is too rich. /forums/images/graemlins/shocked.gif
 
yea id use one of the q jets, they'd work better.

did you get my PM?
get that thing going for this weekend /forums/images/graemlins/deal.gif /forums/images/graemlins/deal.gif

Did you pre-oil the engine prior to firing it and adjusting the timing ? The first running of a crate motor is the most critical. /forums/images/graemlins/k5.gif
 
This reminda me of a fun and just barely related story. I used to have an 81 Lincoln which had the fuel injected 302. One day I was driving it and it started running really bad. My pop in law decided to drive it up the mountain 25 miles to my wifes uncles garage. After a couple engine stalls and 2 hours of driving 25mph we got there and parked it. That night her uncle calls us to tell us the engine and fuel injection system are pretty much shot. The bosch fuel injection system uses a vecuum run fuel pressure regulator. The diaphram in the fuel regulator tore causing the fuel pump to pump fuel directly into the intake vacuum source and into the block. I guess he said the motor was very close to hydraulic lock and the oil was thinned to water consistency from the gas. 1 good backfire could have blown it /forums/images/graemlins/eek.gif I guess fuel got sucked through the vacuul lines killing most of the efi sensors. /forums/images/graemlins/pimp1.gif
 
yea,i run the drill for about 5 minutes, and i've ran it for awhile a few times. :grin.the engine that is. /forums/images/graemlins/thumb.gif /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif
