Budget Build 5.9 for a 71 Scamp

[ScampNYC]

Yes, they cleaned it and installed new cam bearings. Not a caustic tank i don't think, more like a huge powerful dishwasher

repeat after me: it can't be too clean

you'll get a dizzying array of suggestions here: baby diapers, lint free mirco fibers, only [x brand] blue shop towels, part of my mom's first wedding dress with mineral spirits, white gas, brake clean, gas [only premium from x brand because of their additive package], soapy water, WD...

and on, and on, and on.

the point is, clean it. then clean it again. then clean it right before you put it together, and clean as you go.

also ask the machine shop when you pick it up about care and feeding. they might say it's good to goat, rock on billy boy.

Main thing is what ever you use to wipe down the cylinders, make sure that it's a lint free cloth, towel,etc soaked in a cleaning solvent. It may take several passes with a clean solvent soaked cloth. I use 2-3 clothes per bore.

if i got a block back from the machine shop that needed two or three passes per cylinder to clean it off that would be the last time they got my money.

 

[ScampNYC]

Sounds good. I got the block and pistons, plus a bucket of parts I had them clean up for me, back yesterday. They delivered it to my house!

And they picked up my crankshaft to polish it.

They also brought 1 of the heads to show me. As somewhat expected, there is a crack between the seats, which was highlighted during magna-fluxing. The other head was crack free. We chatted about it on the phone and decided to run it .... so I put the head back into their van and they took it back to the shop to get the full treatment.

I’m following your build. I like how you’re doing it.
Get engine cleaning brushes, and clean every single oil passage until it’s clean, then do it some more!

Hey, coupole questions about my oil pump.

First of all, I bought a spring kit just for the plug, so I could replace the plug and properly clean the oil pump.
My assumption is that i should NOT use this high-pressure spring as my build is fairly mild.
Is that correct?

Also, while cleaning my oil pump rotor I dropped it on the cement floor. The sharp edge of the rotor got a little chip in it. Is this still usable? I polished it smooth, it doesn't bind up or anything when I spin it in the partially assembled oil pump.

I'd send it. It's probably better than whatever Chinesium you can buy.

Stock pump, I'd use the stock spring. Any idea how many miles on your engine?

 

[ScampNYC]

I got a message from the machine shop last night. Turns out my crank needs to be ground! I sure am glad I brought it to the shop. I was going to polish it at home and use it. But they said the scratches were too deep and it needs to be ground down. So I guess I’ll be returning my bearings and getting oversized ones.

honestly, that looks pretty pooched.

i'd spring the 50 bucks for a new pump

Yeah, now that I know the crank needs to be ground, seems like whatever scratched the crank probably scratched the oil pump up too..?

Send me a PM and you can have the one out of my rebuilt 5.9 with 6,000 miles on it for the cost of shipping. I’m upgrading to HV.

I thought the same thing, but I didn't want to be the first one to say it.

Melling does offer a kit, part number K-72, to replace the internals of an original Melling pump, if your housing and cover are still in good shape.
