all pics are not from the engine with no oil pressure

1- in the pink should there be a o ring there??

2- in the green if i frogot to install the piston in there could that cause no oil pressure.

3- and the oil pump be bolted in wrong??


theses may sound stupid but i just throwing out ideas...


Thanks Dustin

P.S notice in the pic with the pink the front o ring cover o ring is installed

you found your problem, the piston missing in the green area is just dumping the oil from the pump right into the pan, pull the cover and reinstall it with the spring and you should be golden.

the pic #1 there is no o-ring supposed to be there, it is a clearance buffer for the oil pump shaft.

#3, the oil pump is pretty idiot proof so i doubt you could have bolted it on wrong.

ok, lets PRAYYYYYYYY when i pull the engine apart that the piston is missin...

also it shouldent be that hard to remove the front cover with the engine in the fc???

you may have some trouble with the e-shaft bolt, if you have an impact gun then it shouldn't be a problem though but after you take the front main bolt loose and take the CAS out of the hole then use a flat tipped screwdriver or prybar to hold the timing gear in towards the engine while you pull the front hub out of the front cover, this will keep the thrust bearings from falling out of their slots.

I think I've gotten Dustin, and myself, a bit confused.

First, Karack, are you calling the spring the "piston"? He has the spring in there already, but I couldn't remember what the other part is called off the top of my head and told him it was a piston. I just checked the FSM and they call it a plunger. It says to remove the bolt, spring, and plunger and reinstall after checking for spec. So when I told him piston, I meant plunger, and that's what he's referring to.

But he definitely has the spring already in there.

i just watched the atkins video over again i think i put the spring in but im not recalling puting in the plunger in.. so no pluger=no oil pressure rite?? and yes i do have air tools..

Ahhh, this is why I was calling it a piston instead of the "plunger" that the FSM says.

From the directions I have for a high performance rear OPR and shimming the front regulator it says:

"Remove oil pan and unscrew rear regulator. Install high pressure regulator. If desired, remove cap for front regulator. The spring should fall out when the cap is removed. The piston may or may not come out with it..."

So this "piston" I was talking about is the plunger the FSM is talking about, I'm assuming.

there is a bolt, spring and plunger(piston) in the bore, the spring sets the oil bypass pressure so if for some odd reason the oil pump is supplying too much pressure it will dump the reserve into the pan, if either the spring or plunger is missing then it will bypass completely and have near zero or likely zero oil pressure.

so if the spring alone is the only part in there then it will definitely have no oil flow past that point. (maybe a tiny bit but not enough to go through the cooler and up to the oil filter)


edit: if you are almost certain it is the plunger you didn't install then it may be easier for you to remove the oil pan rather than messing with the front cover, this will require jacking up the engine and removing the right side engine mount though.

Right-o, glad we're on the same page now I was confusing myself at first and then got more confused when I read your first post

Funny how during my rebuild and when I shimmed/replaced the front spring my piston/plunger never even came out either times. Guess I got lucky because I wouldn't have even thought about checking.

im gonna most likely go to my moms house tommarow and work on it for a few hours, atleast just get the parts off and see if im missing it, The one good thing about this, i will never make the mastake again lol
