Jim....looks good.

Thanks my friend!

It remains to be seen what kind of vacuum I can draw with the venturi. I decided to go with a Ford backfire valve instead of the Chinese junk that came with the Summit kit. I'll run a 3/4 inch silicone line from the venturi to the valve, then 5/8" from there to the catch can. I just have so little available space to mount anything. I will find a suitable spot for the can though.

I picked up my oil today and a bottle of Lucas break in supplement today. It has ZDDP to put a coating of zinc on the new parts during the first few thousand miles. Not a huge deal on roller cam engines but a MUST on slider or flat tappet stuff. I figure for 15 bucks I will use some on this build.

I'm ready to install plugs, so I want to get the new oil in and spin the engine on the starter to build oil pressure for a while before i finish the assembly. I'm hoping to reprogram Megasquirt and fire it this weekend.

I really wanted to sandblast the hotside, but the weather is SO bad lately that I just hit them with a 3M disk until they were shiny (but pitted) and then sprayed them with a rust stopper that turns the rust to a black substance that is no longer an oxide. I then heated every inch with a torch until all the solvents and moisture were gone, then wiped it down with lacquer thinner and applied the paint/coating while they were still warm.

I really have high hopes for the VHT. I think they did their homework on this and it is a true thermal barrier. It has actual stone in the makeup, which is what it takes to become impervious to heat. I plan to do the suggested method of curing. 10 min idle, 20 min cool. 20 min idle 20 min cool. 30 min idle 20 min cool. This stuff has to cure out the solvents in the correct way or it never attains the hardness or attachment. It really is space-age technology. (Think re-entry tiles on the sadly defunct space shuttle.) If it fails I have to suspect my prep.

Can you bake the VHT coating in an oven?

You may not want to do it in the oven you cook food in though ;).

I baked some manifolds in the kitchen I thought how bad could it be?

Yes, and that would probably be best since you can control the heat better.

I understand this stuff really stinks as it is baking. A BBQ grill might be a better option?? If I come across a couple 55 gallon drums for cheap/ free I might cut them and weld them together to make a cheap oven. Put a few propane grill burners in the bottom and a thermometer in the top, and be able to cook powdercoat and headers. It could live outside and not take up garage space.

You have a loving and understanding spouse!


If my passengers pipes would fit I would have baked mine in the industrial oven I have here. It won't quite fit, though. When these pipes come off someday I will get the next ones ceramic coated by a shop that has an oven.

One $8 dollar can covered my whole job. I bought 3 and have 2 cans left over. It looks like putting it on too thick causes bubbling, so I was trying to carefully follow what they said on the label. 2 thin coats followed by one medium wet. It covers really well.

I'm not usually impressed with stuff that comes in a rattle can. This seems pretty cool, though. I did scratch some off while I was installing the header. I hit those spots with a little bit more and it blended in fine.

The other DIY stuff I'd like to try is the Techline coating. Their new formula looks very promising.

I likea couple of 55 gallon drums better than a BBQ grill. I think you would get a more even heat and you could fit larger objects in the drums. Plus you won't be using it to cook burgers later in the day ;).

I plan on finding a old electric oven just for the garage

It's amazing how often you would use it

It's all back together. Whew!

I spent time tidying things and fine tuning some things under the hood or I'd have finished a lot sooner. Things are tighter now with the big valve covers and the spacer. I primed the engine with oil with a drill before I got all the front dress on so it's ready to fire.

I broke a cable on MS the other day, so I have to sort that out yet before I can actually crank it up. Maybe tonight if things go smooth.

It turns out it was more than a broken cable. MS isn't talking to the PC, so I can't reprogram it for the new injectors until I get it repaired. Hopefully I can get it out and on the bench to see what's up with it and back in tomorrow.

Yeah, it seems like it.

:roxor:

It's a runner now, though!

 The MS was getting some corrosion inside from laying on the floor of the car. That's what was causing my problems. I cleaned all the solder joints, reflashed the firmware, re-loaded the .msq  file, made my injector changes and she fired right up.

I had to change my idle screw setting to add air, then played with base fuel until I got a stable idle, then took it out and let autotune do it's thing for a little bit. It's going to take a couple weeks of off and on driving to get things dialed in, but so far, so good.

I have to change the venturi location, it is blowing, not sucking. I half expected that, though. I never coated the downpipe figuring to have to tweak the location.

The car is quieter than ever and no evidence of exhaust leaks or any leaks of oil, water,or any other fluids for that matter. All in all I'm a happy guy.

Nice we need some video preferably with smokey tires. I miss the smell of burning rubber
I  pushed the button on fleabay for a spyder intake and throttle body. I'm getting ready for ms2. I'm gonna start with a simulator and relay before the big build. Then all the questions will start.

I wouldn't bother with a relay board, personally. You'll need relays, but not necessarily on the board like that. I have a relay board here that I built and never used in any of the last 3 MS builds I have done.

A definite YES on the Stimulator, though. It is a must have if you ever need to troubleshoot. I just pulled mine out again today to get my box tested before I put it back in. Unfortunately I have never needed a MS2, so I can't help too much. They have different set ups entirely.

If I was going with MS2 I'd probably look to incorporate a GM stepper motor idle control. I am not a huge fan of the PWM Ford valves. That said, if I used MS2 to control one I might be happier since the code is more refined in MS2.

Sounds like a fun project thewestie!

Finished pics. Looks much the same on the outside except for the extra breathers and new rocker covers, which are mostly hidden anyway. But I know you guys like pictures!
