removing plenum update

[Q451990]

Pulling the runners adds a couple of hundred in cost due to the new one-time-use gaskets that you'd need to buy. The plenum outside actually has a paint or surface coating that gives it a little bit of a gold-ish look that might come off in a parts washer. I found that out cleaning a spare plenum, and it looks really bad without the paint.

Bead blasting sounds like your best bet if you don't want to spend the time with brake parts cleaner and various bottle brushes. The worst port that you will clean is the EGR. The carbon crust there at the 90degree bend can feel like solid metal.

There are only two metal gaskets to the runner (One for each head) so that shouldn't be much and you can Autozone them if you want. But I called IOS and they said $114 for all the gaskets that you need and tell them this when your ready to order: 105004.

But if your careful you might be able to get away with using the old ones, But not very recommended.

[unknown007]

Oh man more hundred.Might as well.I'll have to talk about this with my parents and explain how it'll save more time and money.I should also clean all the plugs.

Beadbalsting just was an idea to make it more of a brand new look.And i rather not mess with brushes and stuff been there done that it hurts my muscles.hahaha thanks for helping guys hopefully i get more pics up when i get back on it.

Anybody want mt dew?

[96Qowner]

Keep at it, Berner. We've got your back.

.I should also clean all the plugs.

Exxcuuse me?

[unknown007]

Exxcuuse me?

Plugs,connectors you know what they are? Don't play dumb. Got to clean corrosion.

[silver2k2]

I think he is trying to say he is going to clean the connectors with electical cleaner then use dielectic grease, not clean the actual plugs. replacing the plugs at this point in the restoration is the best idea for sure

well if they look that bad i will.But cant keep throwing money in with out knowing yet what is bad.I'm getting on it right now will have my dads laptop outside with me I can maybe braodcast it too hmmmm.........thinking about it.Will update with the pics.

[mxr662]

I did not remove my runners when restoring my under plenum hoses. Be a good time for checking/ replacing knock sensors and injectors.

[unknown007]

only need to replace two injectors and my knocks are fine.Update i only got the injectors and rail off.The harness too.Fuel went everywhere until i found where to to put the screw to plug them.Had to cut one fuel line off because it was stuck and the hose wouldn't slide off.

[paranoidjack]

I learned by trying stuff and making things work with nothing when I was a kid. Reusing intake gaskets on chevy v-8's. Using permetex gasket sealer on carbs. My buddy used indian head gasket sealer on everything. We even found all the roller bearings except for 2 when we dropped the driveshaft in his duster. It was a pain finding all the u-joint roller bearings on brick streets. There is something to be learned from everybody

unknown007 seems to be trying and asking questions. I will give him credit for that.

Old Q45's seem in the price range for learning

I completely agree...kudos for trying! It's not a $50k car anymore....you have to start somewhere.

[Q451990]

Fuel went everywhere until i found where to to put the screw to plug them.

Did you pull the fuel fuse while the car was running and let it choke down? Also loosen the gas cap to prevent pressure from rebuilding. I once had a driveway full of gas from not knowing that... luckily it drained out on the driveway and not in a runner somewhere.

Heath

Haven't turned the car ever since i brought it here from overheating.

Well i'll take the gas cap off to release some pressure then thanks.

[Infinitiguy19]

Well its too late now, but for future reference.

I should have told you though through the emails.

[unknown007]

Yup well here's what i got done nothing else to do now.Found out I had my valve cover gasket leaking.So started doing that while i wait to order the hoses.Gonna wash all the parts hopefully monday or thursday since i got alot to wash.Will bead blast the plenum and runners if it's safe to do runners.Was thinking of bead blasting all the parts though even the coolant Y one good idea?

Well need help with the EGR removal to get the cover off.I wasn't there when my teacher removed it.Well let me know.

Enjoy the nastiness (from previous owner):

Lots of corrosion will clean with connector cleaner thing.

This one has so much corrosion even the male part to plug in has lots.

I know I know it's disgusting.

Thank god im replacing.



Should've known it was leaking.The rust broke the clamp off.I feel like a bad owner but I didn't know much before now i do Thanks nico fam.

Started brushing this off.

Heres the problem or better say question i have.This ones rusted and seems like it ate a bit off and has a little dent inwards but didn't go through.Should i replace it or keep it?My dad offered to replace but what you guys think?

That's the one that caused the problem last tuesday.Ignore the freshly cut part which i started cutting.Its the part with the goo that broke.

more brushing

other hose.

Looks good so far.I found a screw off the plenum sitting in that puddle that previous owner had dropped and replaced with a scre that doesn't belong that with 3 washers.

Started brushing that too.How can i clean that block area now?Any idea or does it have to stay all black and gooie?

Runners which will be cleaned.

Peak inside.

If i remember injectors go there.

knock sensor

bottom of knock sensor

blurry but has a crack should i replace?

better pic

and it's cracked there too.When i Ohm'd it at school they were fine and also when i Ohm'd it with mike.

[silver2k2]

I would replace those knock sensors, as you know now they are pain to get to.

Make sure you do a good coolant flush once its back together, all of the coolant passeges are going look just like those parts you removed. This car looks like it never had a coolant flush in its life and was filled with tap water when low (mineral deposits) istead of distilled.

Good luck you are on the right track

[unknown007]

actually maybe i made that.When the hose broke i put regular water since i had no distilled in hand.Just to cool the car off.Well I hoping to flush all the fluids and to my oil change,and differential.transmission is good still red.Any idea about the part that the rust ate up?

How much are knock sensors?

[Infinitiguy19]

If the part is aluminum then sand blast it. Or I can see if I have that part too if you want.

Knock sensors: http://www.infinitipartsusa.co...=3221

[unknown007]

dunno if we have a sand blaster at school? will check but any idea how i can clean the top of the block?

[Infinitiguy19]

I meant bead blast.

Do you want to just remove all the coolant up top?

[goody90q45]

dunno if we have a sand blaster at school?

Sand Blast = Bead Blast

.....and it's cracked there too.When i Ohm'd it at school they were fine and also when i Ohm'd it with mike.

The KS ohmed good a few weeks ago but the engine had not overheated. Ohm them now (probes of the voltmeter directly on the pins of the KS) and you will find they're now dead. I think they're about $100/ea from the stealership. A little less on Ebay.

[unknown007]

they dont need the battery connected to ohm do they?

Oh duh sand blast,bead blast hahaha mean the same.Forgot.I removed all the coolant i mean clean it since it's all black now. Let me know.Mike can i sand blast the runners too?

[goody90q45]

You can bead blast the runners also, just be careful to avoid roughing up the oring sealing surfaces.

KS and FI can be tested in your kitchen once they are removed from the engine. You don't need the battery to ohm test the KS (or the FI) if you are measuring directly on the part with both probes.

The deposits inside your coolant hoses didn't appear overnight or from you using tap water last week after the engine overheated. It's from years of PO's using tap water and not changing the soured coolant periodically.

[unknown007]

Oh well then i guess a good 2-3 coolant flushes should do the job agreed?just how though,fill it drive it for a week or 2 days then flush and replace?

Ok i will ohm my injectors again too just to make sure those two were the only ones bad.Anything else i should do or know?

[Infinitiguy19]

Well not to steal your topic, But since the injectors are off with the rails, Can you clean them with brake parts cleaner?

Or is there a cleaner that is recommended to clean them?

What about putting them in a bowl with Redline S1 or BG44K?

[unknown007]

good question I need to clean them too.

[Q451990]

Oh my... that is a disgusting cooling system! The previous owner didn't do right by your car... it's lucky to have you to try to clean up the mess. I would definitely replace those knock sensors and it's harness. Even if they ohm ok now, their days are numbered in weeks or months, not years.

Heath

[Infinitiguy19]

So when they say "Drain and refill" there wrong especially in this situation.

But I never though the cooling system could be that bad, Now is a great time to invest in a BG coolant flush or even a Nissan Cooling system flush that Joe sells.

[Q451990]

This shows what happens when there aren't enough (any?) drain and fills in the past! Joe's coolant flush is just a chemical flush-in-a-bottle... can't imagine it's much different than the off the shelf stuff at the parts places. I think I would do several rounds of a chemical flush. And definitely a new thermostat.

Heath

[Infinitiguy19]

Is there any kind of mechanical flush or any thing else at all that exceeds 23 PSI by a little bit?

The collant system should hold a little more than 23 PSI hopefully, But I would be more worried about the head gasket because its the hardest to replace (As far as I know).
