ok here is the story just installed a 589 598 lift cam with 7.4 pushrods and PAC 918 springs and we started the car and it had a loud tick like a cold powerstroke,oil pressure was normal, so we shut it off and called a mechanic and he told us that the lifters needed to be pumped up and he told us to let it idle so we did and the sound got quieter than he said go drive it so we did, "the car was running good other then the noises " and we got about 8 blocks and its almost like it locked up and the motor died we parked the car and checked the oil and **** and everything looked ok so we cranked it over and it started but extremly loud tick/rubbing/banging from the bottom end. hauled it home pulled valve covers, all springs and rods intaked, drained oil and no shavings on magnitezed drain plug. wut do i check next?
i wanna pull the oil pan but i dont think u can without pullin the motor.


P.S. I MOVE IN THREE DAYS!!! and have no garage where im moving, so allnighters are ok for me just to get it done

Oh also i just noticed that my valve seals are stuck up in the spring

Hook the airhose back up with the rockers off and see if air is blowing threw the valves. Did you check the piston to valve clearance? Did you degree the cam, making sure it was installed correctly?

we did not take the heads off to do this cam we were told by comp cams that we did not need to worry about valve clearance with this setup and the cam can only be installed in one poistion so that it is lined up with the arrow on the bottom timing gear

Are there any valve springs sitting "lower" than the others? Such as all the intake valve springs? Sounds like the timing chain could be installed wrong and the cam is waay advanced/retarded and the valves hit the pistons. Doing what ***** said will let you know that without pulling the heads.

Good luck man.

we lined up the timing marks on the timing gears when we installed it and if we hook air up to it wut will that tell me? that the valve doesnt leak?

willyfastz

So no you didn't degree the cam. And you don't have to have the heads off to check the p/v clearance.

What timing set did you use or did you just reuse the stock chain and gears? Did you torque the cam bolts or use a little locktite when they were reinstalled.

You said you checked the oil but you didn't say if the oil pressure was normal.

willyfastz

Yes, that will rule out bent valves.

and also if for some reason the timeing is "waay" off why would the car "run good" considering it has a big cam

ok i got ya also no all the springs are about the same height and the sound was down low on the motor thats why i was wondering if there was a way to get the oilpan off with out pullin the motor

willyfastz

You asking for help? I didn't read were the car was running good. I red the part about it making noises and nearly locking up on the road and having to tow it home.

willyfastz

Drop the Kmember.

ok im sry the car was running "good" and smoke was comin out of the dipstick and the air filter and the oil fill cap, after we pulled over and opened the hood

willyfastz

Did you fill the radiator with coolant, and bleed all the air from the system?

98camZ

iTrader: (3)

yes radiator is full and temp gauge was normal when it all happend

Did you loose any of the lifters when you took the cam out???

98camZ

iTrader: (3)

also when we crank it over the u can feel a vibration/thumping on the clutch pedal when its pressed down

98camZ

iTrader: (3)

no we used the rods to hold the lifters up and when cam was out i looked down in and all the lifters were lined up correctly

willyfastz

you didn't say if the oil pressure came up after start up.

i had almost the exact same thing happen, only you dont want to hear my out come.. pull your intake off and make sure the valve heads are all there... and no metal in the intake..
