Yes the old gas could cause this problem. Although it sounds like an overly lean condition. The first thing is to get the old gas out of the system. The injectors might be clogged. Also you could have a large vacuum leak somewhere. Torn boot or broken pipe or vacuum line somewhere...

The flip side of that is if you can't verify it's a black pearl and it has all the features it should then the person you sell it too can't verify it either...so if it looks like a black pearl then it's a black pearl....

Found the threads on Black anodes http://forum.caswellplating.com/forum/electroplating-questions/15358-black-marks-on-finished-zinc-plated-item http://forum.caswellplating.com/forum/electroplating-questions/7741-zinc-anodes-turning-black apparently not an issue. On another note is anyone here using the blue chromate prior to yellow chromate?

It's a Shibaura. I believe I spelled that right.... I am pretty sure that's ..."No es bueno!"

The finish on the part seems pretty good. No rough looking at all at least if the part is smooth. I was wondering if the black could be contaminants in the plating solution...

Wow! they want a lot of money for those. Really a time capsule with hubcaps in them....

So in between tearing down the diesel I am working on I took a shot at plating again. Before I started and while everything was heating up I worked on my plates. They were black and crusty and I left them overnight in the solution. I assume that was a mistake....So I started with this and wire brushed them and then sanded them smooth I got the plating solution up to about 120F. The directions for my new power supply say to turn the voltage all the way up and the current all the way down and not to turn it off or on while connected to a load. So you cut it on and short the leads to each other and adjust the current dials until the current is at the level you want. so I started with these 5" pipes again. The first was run in the tumbler overnight. 15 minutes of plate / rinse / 90 seconds of chromate / rinse Thought the zinc would be a little brighter not so flat grey.... The focus is off for some reason. The one on the left is the one from the tumbler. the one on the right was buffed on the buffing wheel. Very shiny before plating. It came out much better...I ran the second one for 120 seconds in chromate. On the second piece the bottom started to burn or turn black from something. Any ideas? This is the fourth piece and has a little flash rust around one of the holes. I thought I would try it for fun This is how it came out all finished... SP degreaser hot / rinse / acid dip for 20 seconds / rinse / plate for 20 minutes / rinse / chromate for 2 minutes Not very noticeable but still there Did this one too but there were areas where the texture wasn't smooth and it sort of looks like pits with zinc in them but they didn't yellow with the chromate I came up with pretty good color. Still have to work on the finishing before plating. I need to come up with a good solution to make them smooth. If the finish was smooth enough I could get the color pretty good. One issue I ran into was after chromating I rinsed it and some of the chromate rinsed off along the edges where the finish was smoothing. Has anyone else seen this? This is how the plates finished. Does the black affect plating? What do your guys plates look like?

I thought I would throw this out to the smartest group of mechanics I know. I am working on a diesel 4 cylinder that is Japanese made and came out of an old New Holland skidsteer. It threw a rod and I am exploring rebuilding it but haven't ever built a diesel before. Anyone here have any experience? These get expensive quick and I don't want to go through all the motions and still not have a running engine...any advice?

Guy, I believe the correct term is "Diseazed"...

@Montezuma

I believe Fedhill can supply all that you need for the hardlines and they have a tool rental program too

Sounds good

Have you contacted Ztherapy yet? That is where I'd start...

Love those triples

501!!! Love it...

I love it!!! I also have 5: my oldest is 20 and the baby will be 12 this year. Unfortunately I haven't had a running Z for them but I have built cars for some of the older ones. Started a 73 fast back mustang with the older one, a BMW Z3 for the oldest girl and a 510 Wagon for the second boy. Enjoy the memories, that is where the real treasure lies...

Have you checked the antennae lead yet?

I used both lizard skin products in the car I am doing the insulator and the heat shield. I sprayed the whole interior of the car, quarters, door interior s and the roof skin. the sound transmission is much better. I may still add some sound mat on top of this. The additional weight is not of concern for me...

R-12 is really a more efficient refrigerant too if not as environmentally friendly. It will be cheaper to not convert it. As for your existing pieces I agree find a competent AC shop in your area. It will save you money in the long run

I would use an oil paint. Some interior oils will yellow with age (like Site said) but the better ones tend to do it less. It is really a function of UV exposure. I would expect a gallon of oil is $60 or more. If you're going to do this in a confined space, lots of ventilation and a respirator or you will be high as a kite...

Blue who!!!!???

Love it!!! Congrats to both of you!!

Yeahhhh, no!!! Maybe a gas tank liner gone bad? Or a bad rubber hose that dissolved into the gasoline, vent hose maybe????

I thought Mike at Banzai motorworks had them but I can't find them on the website...

I bought two limited slip rear ends with drive shafts from him several years ago...
