well i am lost here i guess i need to pull the motor out and see whats up
i have a solid roller motor that never had great presure but all the sudden it droped to like 18 at idle and didnot really go up when i jumped on it
this motor has like no miles on it
then that same night i was racing and it totaly bottomed out so i shut it down right away and let it sit then fired it up and it had some preasure
so i got it home and i figured the oil pump went out it had a LS6 ported pump in it but i put a new one in and still nothing no preasure at all
i have two gages hooked to it the factory one and a auto meter mech. one
i pulled the intake and took the fitings out of the block and turned it over and no oil even comes up in the hole
any one had this before any help here
thanks ahead of time

i have no idea but my car is doing the same thing got the pressure checked it was low then i foundout the pump was junk so i put a new one in and the same thing so if you find out anything about it could u let me know thanx

2000TAguy

well cross our fingers here but i think i found the problem
i am running a solid roller and a air pump on this motor so i needed to restrict the oil from the top of the heads IE restrict the oil that gets up through the pushrods
so i used a old school small block chevy trick and put pipe cleaners in the pushrods
i found out today that they started to come apart so i have all kinds of cottin fuzzy stuff through the top of the heads
so i got a mess to clean out

Did u use the stock O ring or did u get a new one. My buddy had this problem also right when he put the new motor in and had the TR pump put in. They changed the O ring and i never heard a thing about it again. We where out running the cars the other day and i drove his and it had presure so i guess that is what was wrong with his motor. Might want to try it before you go and pull the motor. But it would suck if it was somthing else and u wasted money and time.

2000TAguy

yeah i checked the o ring when i put the new pump in saterday
and i use a new o ring every time the pick up tube comes off it is a cheep part to replace and not worry about
i buy them 25 at a time from the local dealer

i think i just got fuzzy stuff clogging something up *LOL*
not really funny but you gotta laugh
i mean nothing in the motor is hurt just some times wasted cleaning things up


also ian you might want to cut your oil filter apart and see how much brass you see in it thats the bearings if the mains are wiped it will not carry much preasure

Let me get this straight...

You put pipe cleaners...

In your pushrods???

Dude. That's weird. You shouldn't have to do that. That's just.... wrong.

2000TAguy

the pipe cleaners in the pushrods is am old school trick i have done for years

it restricts the oil from the top of the heads

the Moroso vacume pump i am running was sucking raw oil out of the valve cover and blowing it out the breather

What kind of lifters are you using

2000TAguy

crane solid lifters

I'm guessing you have junk clogging the oil pickup. That engine's probably not long for this world...sometimes lessons come expensively in the old school.

I was building engines in the late '80s and never heard of shoving things into pushrods. Little $5 Moroso restrictor kit always did the trick.

And why are you using a vacuum pump? Honestly, sounds like a patch on a band-aid...

CHRISPY

An old school trick that probably wiped your motor.

I can't believe you would do that with a LS1 LOL!

2000TAguy

humm lets see here a vacume pump makes HP
there is more than one LS 1 out that uses them
and no nothing is hura at all all it did is take away preasure not valume
the gage just did not see any oil
and lets see chris 11.10 not bad but i went 10.60 at 4200 DA 3500 pounds
it will take me about two hours to clean a few things up and away we go again
oh yeah the guy that i learned that trick from has only held 12 differnt NHRA records over the years so what does he know

the trouble here was what ever the pipe cleaners was made of all fell apart

2000TAguy

damn chris is that a 385 cubic inch
damn man go get some money back i went 10.81 on my stock bottom end and a hyd cam

This is probably your problem all along. If you run the crane SR lifters you must have the lifter bores sleeved. I know Comp. is making a new SR lifter that will work without getting the lifter bores sleeved. Those are what is in my car now. You need to call them and find out the part number, I do not know it off the top of my head. I had the same problem 2 years ago on my first SR motor. It will idle between 20 and 25 psi and when you run it hard, it does not go above 35 to 40 psi. This is not enough oil pressure to keep the bearings oiled at high rpm. You probably spun or damaged a bearing. This would probably explain why your oil pressure has dropped even further.

10.81 is nice for cam only.

What raceweight/transmission and did you spray?

I just find it unbelievable that someone would jam something like that in their LS1 LOL!

I run the new Comp drop in solid lifters. They're much nicer than the old Cranes.
Pipecleaners used to be the trick back in the day before they had galley restrictors. They didn't last very long though.

2000TAguy

10.81 was at 3380 race weight with a 350 turbo and no i have never sprayed my car
but after i 9.99 an motor i am going to spray it

yep....very old trick.....nothing "wrong" with it but there are better ways to do things....




well how "bad" was the oil pressure? I'm going to hope you have better luck than me but I'm fixing the results of low oil pressure myself.....

When I built my 388 all bore we tried to build it a little looser than standard but I guess we went too lose on the mains. It would get 45psi at cold idle but would fall to about 15psi when it got hot and would just reach 40psi at hot WOT. ......well long story short, 450miles later I spun the #8 bearing and get to redo the crank (I hope it will clean up that is.......... ) ..............

i was gonna ask what kind of pipe cleaners he was using
