Off to the machine shop

Stephen00TL

Hmmm that's weird. It will still be good once you finish all that work

fsttyms1

Hopefully ill have the block back by the end of the week now that i received the block guards

I wish the machines at work were small enough to do side jobs but unfornately for me my machine is huge as fuck and all my hardware is huge so can't even secure a small job if I wanted to. Maybe after my shift I could go up to the tool room but even then I'd have no fixtures. Just have to open my own shop I guess.

fsttyms1

you have access to tig welders?

MilwaukeeDave

iTrader: (3)

All welders. There's hundreds. Just gotta find someone willing or pay em a little bit but usually I can get someone to do it free.

fsttyms1

hummmmmm Road trip

I'm looking for the fucker right now. I got my lowers I'm working on that I just got. They had a crack that was only repaired outside so I ground it out some now I'm gonna have him fill in the crack then I'll get it looking like brand new. These older guys here wander off and can be hard to find sometimes lol.

Carson-TL

Dude.....I wan't to be you right now.
Like, how do you have the knowledge to do that! I mean we all dream but dude...ah man, I'm mad right now, like I feel like my life is worthless because I can't do any of this stuff and you just do it for fun on your weekend....damn.

A4 headlights, 6 speed (WHICH I REALLY BADLY WANT), engine parts everywhere, an awesome looking dash, then you just go ahead and buy new trunk and door panels, AND You have a Nice Malibu Boat!!!!!!???? I am freaking jealous.

Here's what I got going on here. I bought these runners and from what I've been told they were ported and polished by Paul (NVA-AV6 is his name I think) the outside of the crack was welded pretty nicely but nothing inside. Though he said they don't leak, I'm not taking any chances. Here's some pics:

Here's how they came:


I ground out that weld booger and dug into the crack to make room to be filled w weld:



The polish on these is pretty good but they could use more porting. I'm gonna start on the one not cracked while I wait on my welder and just go up to the line I see from the gasket. Then I plan to hone both mating surfaces and throw them puppies on.

MilwaukeeDave

iTrader: (3)

Are you opening up the whole runners to the gasket size or just the start of them??

fsttyms1

i just do it. i dont worry about if i can do it or not, i go into it like i have done it before and just do it. Just dont be afraid to try. Its not like i had experience putting A4 headlights in before, or like i have ever rebuilt a motor before my first time i ever rebuilt one. You have to start somewhere. Plus with the advent of the internet you can literally find anything in minutes if you need help.

fsttyms1

If they are welded up on the outside they should be good. How did they get cracked? My tig welder is broke but i can aluminum rod braze them. Bring them up.

The whole thing is getting opened up. I have found the heads have the most to gain from this. There is a lot of material to remove which should allow for some serious flow and good gains.

MilwaukeeDave

iTrader: (3)

I got a guy a work says he can fit his TIG torch in there and fill it in for me. Ima go get it back tomorrow hopefully. Then I'll grind and polish it back to nice again. I can see the old gasket marks so I'm gonna open them up to that size then maybe I'll attempt the heads on a weekend off. Did u just stuff mad rags inside the heads to keep them free of chips? Hopefully this goes well. I've read not to polish to too fine of a finish or it will interfere w atomization of the fuel due to lack of turbulence in the air. True or false?

fsttyms1

My heads are off and sitting on my work bench with the valves and everything out of them. Im not sure i would do it with the heads attached. You wont have enough room to maneuver i in there to do it properly on the vehicle. Plus with them off you can open the exhaust side as well.

As for smooth or not smooth, the jury seems to be split on that. Personally i dont think it matters on modern fuel injection setups like ours as the fuel injector sits just before the head and there is no need for turbulence up in the intake or runners to mix the fuel Maybe back in the carburetor days where it dumped the fuel in before the intake.

MilwaukeeDave

iTrader: (3)

For the middle of the ports are you in there w a flex hone or just a normal grinding stone?? I'm running out of tool length w my current setup.

fsttyms1

Both. Ive got all sorts of stones (i find the ball shape to work best once you get in further). Im also using port and polish kits like these



You can get a good set of these at Harbor freight for like 20 bucks



And when every thing is said and done ill use a set of these

fsttyms1

This is a good video to watch

MilwaukeeDave

iTrader: (3)

Awesome. Thanks a ton! Here's what I got so far, started on the head side:

fsttyms1

Looks great

fsttyms1

Did a little work to the heads today. There is a pretty good lip where the valve seat meets the head that i was able to smooth out, and some pretty decent casting marks that need to come out. I wont go much smoother on the intake ports here to allow a little turbulence to help atomize the fuel. Ill just clean things up a little. When i get to the exhaust and combustion chamber side ill polish those. Ill also take a little lapping compound and clean up the valve seats and valves.

Stephen00TL

Wow good job that looks great

MilwaukeeDave

iTrader: (3)

Wish it wasn't my daily so I could pull the heads and get this in depth. Or that I had money for new heads or even better type S engine!

fsttyms1

Strip them down on a friday night, take all day sat and sun to port n polish and reassemble sun evening. It can be done

fsttyms1

Machine shop called and said these have been installed and welded in, the block will be dun monday

MilwaukeeDave

iTrader: (3)

I don't have your skills w these motors plus I work most every weekend. 12 hour days this weekend too. Plus I can't occupy the garage overnight because they'll break in the van if left out so any extended job I gotta do outside and right now the weather won't allow that.

MilwaukeeDave

iTrader: (3)

Does this prevent piston/valve interference in the event of timing belt failure??

fsttyms1

No, The J Series is an open deck design motor. These take the open deck design of the J and close them (the space around the cyl walls). It gets put in to stiffen the cyl walls from "walk" slight movement which distorts the cyl.

Open deck


With block guard in place

Making a very reliable motor even more reliable = winning. Dumb question, but how's that held in place? I don't see any weld.

fsttyms1

(thats not mine, its just a pic to show where it goes) It can be held in place with red loctite or a few tac welds. Its not a loose fit, its very tight.

fsttyms1

Started porting, smoothing things out and gasket matching on the Exhaust side of the head. There is a TON of material here to open and match. Now ill have to see what can be done to the headers or see if ill have to build new ones. This thing should really flow now.





Gasket matched





I want these headers. (yes those are on a J series)

Stephen00TL

Looks like its coming along nicely, I think with the motor set up your going for you will need to do a custom set of headers. It will help make more power and wont be as restrictive as the basic aftermarket headers.

fsttyms1

Yea, i most likely will make a set, ill probably do that sometime in the future (this summer) Maybe head down to King motorsports and see if they will make a set

Stephen00TL

Good idea I think if you didn't it would be a weak link to your new set up.

fsttyms1

I dont think it would be that bad, but i know there are gains to be had which is why i will probably make my own. (i really need to get my TIG fixed)

MilwaukeeDave

iTrader: (3)

I gotta take some time and practice my welding. Been machining so long that now I just grab a guy from the shop to weld for me. We are paid by the hour so they don't really mind, lol !

fsttyms1

You wouldnt even begin to imagine the things i would have done to the car by now If i worked at a machine shop. Seriously, take advantage of it

fsttyms1

Or i will

this thread is awesome.
