Help,Engine spilling all its oil.

[emiliog2276]

So my car has been without an oil filter tree for some reason. The oil filter has always been attached directly. Ive obtained two oil fiters trees at a junkyard. I installed the first one and as soon as the car was turned on all the engine oil was spilled out from from the where the oil filter tree is attached. Ive tried the other one and the same thing happened all the oil was sprayed out. I installed the bracket with a new oring, gasket and bolts.

Does anyone know what might be causing this?




How oil filter is directly attached at the moment.

Are you sure the sending unit next to the filter is not the one leaking. Had one in an Altima that sprayed oil all over the place, out of nowhere, just driving down the street.

Make sure you get the correct gaskets and orings to the tree. Another thing to check is to make sure the oil filter has a o-ring and does not have 2 on it. Like one sitting on top of another.

Can you get another picture without the oil filter on? and also a pic of your filter trees?

And what kind of gasket did you use to attach the filter tree to the block? paper?

I'm having the same issue, I think what the issue is is that the oil filter tree isn't pressed down onto the block all the way before you torque it down. The o-ring can hold it off the block and can be difficult to get it all the way down to seal. I've been thinking about making a cork gasket from the gasket maker stuff from the parts store. I think it would hold the pressure since the OEM gasket is a paper gasket anyway. The best thing to do would be to get a friend to start the car while you're under it to see where it's leaking from. That way you can see exactly what is leaking. Whatever you do don't go past the torque spec on the filter tree. It's 8psi torque. If you do you'll break the filter tree.

The sending unit next to the filter does not leak. It leaks from where the area where the oil tree and the engine block meet. The picture posted is how i currently drive it with the oil bracket bypassed and the oil filter connected directly to the engine block.

How I installed the bracket was the way its shown in the manual but i also left the the sending unit installed on the port beside the bracket so i had two sending units installed one on the bracket and one on the sending port.

Will try to get under it again and take a picture.
But what you see is the 3 holes around the threaded area where i currently screw the oil filter on. Two of the three hole have a pressure relief valve installed both still have tension to them since when you push them back they close back again. I obtained replacement relief valves but i couldnt figure out how to take the old ones out. I used the nissan paper gasket to attach the filter tree to the block.



Both oil tree's are from a a non turbo z like the one picture, i know the turbo ones have the pressure relief valves in the bottom where the oil filter is attach which these the not. The relief valves are on the block.

Screw the paper gasket and just RTV it?

[z32loverboy]

I did that and it blew past in after 14 miles. The new oil pump puts out 60psi so rtv won't exactly hold that. That's why I was thinking about using a cork gasket. It's thicker than the paper gasket but stronger than rtv.

I would imagine though that the majority of Z's out there still have the factory paper gasket and their car is running just fine.

Have you changed out this o-ring? (circled in red)



And I'm assuming you scrapped off the old paper from the original gasket before trying to install the new one right?

When I reinstalled mine, I did it with a paper gasket and it leaked. I probably didn't tighten to bolts enough though. I then installed it with ultra copper RTV and it hasn't leaked since, and yes my oil pressure goes all the way up to ~90 psi when its cold out.

That's what i was thinking about^

Yeah I replaced the oring with a new one.Old gasket was scrapped off with razor.

Would the two pressure relief valves be a reason for this? Couldn't figure out how to get the old ones out.

Also for the rtv application did you use that alone or in conjunction with the paper gasket?

[Recian]

Just a thought but have you tried with other filters? Maybe they're a bit restrictive causing excess pressure buildup. My car has the original paper and doesn't leak. I know prep prep prep is the key to making it seal. Did you get paper ones from Nissan?

I used RTV by itself, no paper gasket. Ultra copper rtv by Permatex.

And are you talking about the two check valves in the block? or on the tree? (NA engines have them in the block, TT engines are in the tree itself)

Yeah, mine has them on the block. I bought a replacement for the valves but i couldnt get them out.

I went to the junkyard and got another oil tree but this one if from a twin turbo. I know it fits but will there be an issue because of the check valves on the oil tree?

[t.mcginley.jr]

Yes, you there is only supposed to be 1 set of check valves, either in the block or in the tree. Too many might cause problems. You should be able to drill the check valves out of the new tree. You will also need to cap off the port(s) that normally go to the oil cooler on a TT.
