Reassembling EA82T/worked plenum(pictures)


Recommended Posts

Slowly getting the parts and pieces in the mail. It's like Christmas but Santa wears brown and drives an aluminum bodied box truck.

 

Finally started to reassemble the various parts that I had torn down for cleaning and repair. Couple pictures.

Back at it,

Got these pads at Harbor Freight and the chuck to fit into the drill.

 

Most of the cleaning was done with a toothbrush and varsol(sp). What can I say,

I'm waiting on my gaskets and engine parts.

I haven't posted much about my RX.

People have forgotten about it. That's a good thing.

Bird thingy anyone? what is this thing?

 

 

Finally getting my parts.

Now I really have to get to work and making everything ready for the reassembly and installation.

 

Thanks for the compliments.

Scot, my b-i-l, makes jokes that it's the obsessive/compulsive disorder in me coming out.

 

I think the cleaning is kind of cathartic. I look down and 4 hours have past.

 

 

Updates to follow if anyone is interested,

Jay

:banana: You really did a great job, know it must have been allot of work, but that aluminum looks great polished. Maybe you ought to try and seal it. POR15 makes agreat clear and very tough clear sealer. They even have it with a little colered tint to it.

Wasn't really going for the polished look, but alot of the aluminum had that funky scale on it and the only way to remove it I found was just to keep cleaning. I still have several cans of high temp clear from doing my wheels if I do clearcoat the alum. clean=cool. How does paint effect that I wonder?

 

Now that my parts are on the way, I fear that I won't have the gumption to tackle the intake assembly as I would really like. Really want to get it running.

 

Replacing all the hoses and relooming the electronics is still my plan. I don't much look forward to going to the dealer for all the preformed hoses and such.

 

As far as the bird. I was also thinking Subaru farmed out some parts.

 

Regards,

the machinist I took my ea82 to said that painting an aluminum engine block is about the worst thing you can do. Said something like, the aluminum has pores and needs to "breath" to dissipate heat, where paint will fill the pores and impede cooling.

 

So, that's what one machinist said anway...I was never motivated enough to paint my block anyway so I never looked into the veracity of his thoughts

I hope you don't use that machinist for her professional skills!

 

Hmmm. Here's food for thought: why were aluminum motorcycle engines from Jap mfgrs painted silver for so many years? That's right: to keep the corrosion down. Aluminum alloy corrodes pretty easily, though not as easily as steel.

 

Metallurgical dermatology! Subaru engines with pimples! I got a real chuckle from this one ;)

 

Painting aluminum parts (or, indeed, any parts) adds insulation. Some paints impede heat transfer more than others. It has been said that flat black radiates heat better than gloss white. I'm sure that someone better grounded in thermodynamics can confirm and explain this. Skip's last question in this area made me think too hard :)

 

Automotive radiators with cores of copper are almost universally painted flat black -- coincidence? And aluminum core radiators are unpainted.

 

Summary: if you need the best absolute heat transfer, I think that unfinished will yield the best results -- in the short term. Long term, and for most applications, some kind of finish may be desired, to keep the corrosion down.

Sure paint will lose you a little cooling, but even on an air cooled motor it wouldnt be anything to worry about. I mean you can still burn your hand like nothinin else on a painted motorcycle cylinder head. As for the radiators, I think that the copper ones are painted black cause a blue-green oxidized rad looks gross, whereas aluminum never looks really bad it just goes dull.

Tell ya whot Jay, definatly looks sweet. Nothing quite like a freshly cleaned motor. Except maybe if you go nuts on it, and polish the aluminum :rolleyes: But thats almost too much time and effort to be worth it. Keep up the pic updates, a day source of Soobie P**N is good for the soul.

 

Oh yeah, I think that bigjim hit the bird emblymn on the head there. The cam baskets where prolly made in the Robin plant, which is (was?) a different building on the FHI Gunma plant.

Taking tomorrow off. had three bolts break off in the intake manifold. I have gotten this far and no broken bolts, so I was actually surprised when it happened.

One was just a hold down bolt for the purge system but the others were for injectors. Drilled one out, then proceeded to break the EZ out off in the hole. Stripped all the stuff off the other intake manifold and back to work. Thank goodness for the parts car. I was going to use the other manifold as a template for putting the RX's manifold back together. Now I'm glad I took pictures.

 

Turbo assembly in process.

Thanks for the info on the bird, BTW.

 

"Soobie P**N" I don't get it.

It better be... Your Brat and Jay's RX make the trip worth the drive for half the country:D :D :D

 

 

Jay, "Soobie Porn" = Pictures of Subarus that cause excitement and arousal...

 

 

This is definately Soobie Porn
