It is filthy and here's the cylinder that the COP was white:





It's stuck, with the thick hoses being in the way, it's a total PITA getting to this. Got the socket in there and it's just not turning.

The 1-3 Sps had 5-10 foot lbs torque on them too.

 

Oh my.

You have some work to do FF.

 

Hoses ? Oh the core hoses ? Well, by the looks of it, you need to go thru it anyway. Like take the manifold off. Chances are you need intake gaskets. New gaskets from the intake up. Clean the coolant system out, - drain the block/replace coolant. So just remove the hoses from the bottom clamps only. Replace those clamps w/heat clamps. Most everyone sells these clamps now. They're light torque clamps that expand and contract with heat and won't cut into the rubber.

Take a small pic and break up that corrosion in the plug chambers. They sell cheap small pic kits @ Murrays/O'Rielys. Usually 4 pics for a dollar. Then Blow them out w/compressed air.

If you do intake gaskets, get those at the dealership for your EXACT model year and build date. Gaskets changed mid year ALLOT.

 

I guess I should read this entire thread first, don't think I have :o

 

I highlighted the hoses in the way. Are those filled with anti-freeze? Is there anything I can put into that cylinder to eat away that corrosion?

 

Yea, those are the heater core lines. You have one clamp circled in blue. Mann, there's just to much in the way for what you SHOULD do IMO.

I would take it right down and build it back up solid. Actually, start @ the heater core hard line O-Rings, Intake Gaskets. Remove the battery, then the harness plug cradle on the firewall, clamped ends @ the heater core hoses. That way you can use bungies to tie all that back and out of your way. I mean you have to be able to see what your doing to do it up right. Like I said, it's time, it's needs to be gone thru, cleaned and re-gasketed.

When you done doing this, you won't have to get in their to fix anything else anytime soon. Otherwise, you may have to tear it back down soon for something simple, -know what I mean, like a leaky gasket,o-ring or whatnot.

Get down to this, then bring it back up -

 

As far as something to assist with corrosion. Maybe something like PB Blaster in the plug chambers, BUT ONLY after you break most of it up with a Pic Tool or awl. It should break up fairly easy once you can get to it. Yea absolutely DON'T touch those plugs until the chambers are spotless. Use common sense of course. You'll need compressed air or it's going to be a PITA.

 

Yea, down, then back up. It's easy to do with these engines, it's a little time consuming cleaning it up right and not skipping anything, but that's what you want to do to be thorough and for the best possible outcome that will last.

 

Jbrew, thank you for all those photos, and I don't mean to be a PITA by asking so many questions, thank you all for taking the time to answer all of this for me.

Are there any special tools for removing those hoses? When I press/squeeze them, I don't feel anything in there, but want to be sure before I take things apart and coolant spews everywhere.

Where I circled in blue, I have another clamp which clamps onto a solid metal hose which goes into the firewall. Well if I take the heads off, at least it will be easier to put the time sert in

Just trying to stay positive. Off to I to take this apart some more.

 

No problem, plug up that PCV hole, so nothing makes it's way in.

Why are you removing the heads or thinking about it ? That takes a little skill keeping the timing straight. If that gets screwed up, it may cost you a motor once cranked.

 

Yea, ONLY remove the hoses @ the clamped ends as I posted above. Otherwise, you'll need new hoses and those two are very expensive.

 

Hole is plugged. I'm tired and I said the wrong thing. I meant the alum intake, that the fuel injectors and SPs are in. The alum part that's in the middle.


The hose I circled had a 10mm hose clamp on it, removed that and anti-freeze came out. Not a lot, but I was able to catch it.

 

Well I did say not a lot, but now the antifreeze from the spot I circled in blue trickles out, I move the black hose, more comes out. Do I simply just plug both hoses and problem solved? Or do I need to drain the whole coolant system? And if so, how?

 

And I just saw you said to drain the coolant out, well I'll grab a few buckets...

 

And I grabbed some buckets however I can't seem to find the drain plug. I read in the book that it's near the oil drain plug. Is this true?
