Default Sealant used to assemble motor - do you need the 5 different Three Bonds rec. by FSM?

Getting ready to assemble my motor. I have the assembled short block, but the inspection plates/plugs are still off. Reading the FSM, it recommends the following sealants for assembly:

Three Bond 1105 (004403010) - piston/rod service plugs
Three Bond 1207C (004403012) - oil pan
Three Bond 1217G (K0877Y0100) - oil separator cover (plate inside bell housing)
Three Bond 1324 (004403042) - oil separator bolt and oil pump bolts
Three Bond 1215 (004403007) - oil pump

Please tell me I don't need to order all of these.
I don't want to cut corners, I want to know its done right, but can anyone shed some light on this?

Also, any other sealants or supplies I'll need specifically just so I'm prepared?

Thanks,
Bryan

For myself, and many others here.....Permatex Ultra Grey does an excellent job for all sealing needs. It's all I use unless someone brings me fujibond with motor parts.

Ok thanks, I assumed that all of these weren't required.
I did purchase a tube of "The Right Stuff" based on recommendations here a while back for engine assembly but I can't remember if that was for all purpose use or for something specific to be honest. I've read it works great but is also impossible to get off later so I don't know if I should be using that everywhere or just stick with your recommended Permatex Ultra Gray.

Plus two on the ultra grey no issues. Don't forget your aluminum washers.

That's for exhaust gaskets but might work for engines to. I just use the grey stuff because I alway have and it works.

Thank you for bringing that up... this short block was machined to 99.75, assembled fully, then taken back apart and machined to 100mm instead and reassembled. The builder did not put the access plugs back in the second time, but he sent everything back in a ziplock bag. Here is what was in the bag:



The three wrist pin access holes all use the washers, but what else does/doesn't? There is one more larger washer and one smaller one. Is this complete?
I have a complete engine gasket kit so I should have what I need, I'll bust that open tomorrow and reference the FSM again but from what it looks like, some of the plug use washers and some don't? And some plugs have a red residue on them... sealant or thread locker I'm assuming?

I should also have a new rear main seal I hope, but if not I am thinking this one should be ok to insert again, it looks as new.

I know at the end of the day I always want to go back to the FSM as a reference and follow that to a T, but if anyone has any input or tips they're appreciated.

Thanks!

Never re use a engine seal. Even if it was only torqued in place.

You're right, not worth the risk of a leak when its so much work to get back in there.

Can anyone answer which plugs in the picture above use washers and which use sealant / thread lock? Just want to make sure I'm doing this part correctly and the FSM doesn't goes through this part pretty briefly, if it goes over each one then it must be in a different section than the handful of pages of engine assembly that I found.

Every single plug in the pic uses a flat metal washer?

One large
Three for wrist pin access
Six other slightly smaller
Two little guys

Is that correct?

Did an inventory of my 'gasket kit' tonight and it looks like it has none of these... What the hell Subaru?

I think so. They probably assume you won't pull the oil galley plugs I use these over most the time.

No they don't use those washers. All I did was put some ultra gray on the threads and screwed them in.

This diagram shows all of them using a washer, except for the large coolant plug on the bottom of the motor.

I circled each one in question and listed the part numbers for the washers at the bottom of the image.

(5x) 0370S*B ( -0306)
(1x) 0370S*B
(2x) 0370S*A
Large Coolant Plug on bottom of motor does not use a washer



I also noticed that all of the plugs had a red residue on the threads which I believe is thread locker. The exception was the three wrist pin access plugs which had sealant on them (and a washer) as outlined in the FSM.

I just edited with a marked up version of the diagram circling each of the plugs and seals and listing the part numbers. I couldn't find this info anywhere on NASIOC surprisingly so hopefully this helps some others who are building a bare block.

If there are any seals not included in the full gasket kit please let me know so I can order those also!

There is one other opening on the bottom of the motor that is a coolant port for the OEM oil cooler. I'm not sure if this one uses a washer or not, in case anyone here knows.



Here's a photo I found online showing the fitting that goes there

Ha yeah I took it apart 11 months ago, so my memory is a bit rusty. I did label the parts that came off and drop them into a divider tray so thats my next stop to check when I'm home tonight.

But based on talking to the dealer, the coolant passage in question does not use a seal.
