ok i got my buddies motor all together and went to start it up and did have any oil press. i took out the dis. and found that the hex rod in the bottom of the dis. was missing. Why question is. does that normally happen, is it just in the oil pan or did it fall somewhere else?
ohh yea it's an 88 5.0 i am working on.
thanks

yeah definetly not suppose to fall out
it should be in the oil pan or even in the motor
if the shaft still has the reatainer ring from the factory it will stay in play even upsidedown because it is logged beween the block and the oil pump receiver, cant fall out unless installed wrong ![[patriot]](graemlins/patriot.gif)

leaving the retainer clip off of say a hardened arp oil pump shaft, installing it, and then turning the motor upside down
or he just plain forgot ![[Big Grin]](biggrin.gif)

well the car didn't go upside down. and the car ran before. we were replacing a bad lifter then it turned into a cam and heads swap.
so you say there is a retaining clip in the bottom of the oil pump holding that rod in.
and i don't think it could have been installed wrong because the car was stock before this.
thanks

So the motor never left the car right and it did have oil pressure before the heads and cam were removed. Also after you fired it up and saw there was no oil pressure you removed the distributor to find that the oil pump drive shaft wasn't there. From all this the only only logical explaination is that you snapped the oil pump driveshaft upon fire up in two. The lower portion fell into the oil pan and the upper portion broke and also fell into the oil pan as well. Try getting a magnet and sticking it down the distributor hole and see if it picks up the driveshaft. Either way it sounds like the oil pan is coming off to reinstall a new oil pump driveshaft and to determine exactly what went down

When you reinstall the driveshaft you want to postion the retainer on the driveshaft properly. In doing this you want to have it close to the block surface so that when you pull the distributor out the driveshaft will not pull up out of engaugement from the pump with it but you still need enough clearance between the retainer clip so that it is not touching the block surface.

If the driveshaft did snap there was a reason why it did. I'd replace the oil pump and flush out the pick up tube as well since you will have the oil pan out

Well if it is still in good shape but in the pan than there must not have been a retainer on it before. If in good shape I'd at least check the function of the oil pump either by hand to make sure it spins freely or by using a drill motor on it to see if it makes the proper pressure

No problem,
We tune with SCT software which is superchips custom tuning. We tune each car both on the dyno and on the street. Theres various options from a standard chip, or a switch chip depending on your needs

yep, to remove the oil pan, you have to raise the motor, a cherry picker would be the only real way to do this. once you got the motor up, its very simple, theres just a bunch of little bolts holding it in place, but dont worry there easy to get to. dont forget to un screw the low oil sensor from the oil pan.

I use an engine cradle to suspend the motor up. After that the front suspension is removed along with the K-member to gain access to the oil pan. Yes you can reserve time to tune your car with PMS or any other tuning software you have

You can do it with a cherry picker with the tranny in but it limits the height you can raise the car up and the legs also get in the way. Either way works though

In order for you to take the oil pan off.. you need to get to the bolts that hold it in place. and in order to do that the motor has to be lifted up a few inches.. ther for you need a cherry picker, or jack it up and put wood blocks on the sides of the motor.. you will have to unbolt the motor mounts in order to lift the motor up.. Good luck..

thanx for the help guys, but it turns out the oil pump froze, and the rod was twisted AND snapped as well. just so you all know it is possible to replace the oil pump with the pan dropped down but still in place with the cherry picker lifting up the motor.

Ummm... you can tray and replace it with the motor still in but it will be a bit harder.. oil pump froze? might consider that the bearings might have gone bad when you tried to start it..
