Glyptal is brilliant, but...clean [rust free], oil free metal is a must. Even the soluble oil from machinist cooling fluids has got to go - scrub down with mineral spirits 2x, then dry before application. That makes this an indoor job to keep flash rust from rearing its ugly head, and that means a respirator. I sometimes use it on odd aluminum pieces where I want electrical resistance, such as a ballast resistor mount [wire wound resistors can sometimes do odd things when they fail]. When I do, I like to prepare the fitted piece with alodine first: the acid prep clears off minor surface oxides, and the chromate of the alodine seals the surface - squeaky clean and ready. Two thin coats of glyptal, and done. Aluminum does not corrode deep, but it does corrode fast - I have seen many a powder coating on aluminum fail because looking new from a mill, they probably only degreased... but the oxide was lurking, and the coating llifted - then cracked - game over.

These are all the things I should have done to my l28et. You should really take the runners out of the exhaust port and put a header it. With a decent Cam and everything you've done... it would run pretty well.

Sweet! Just bought a 280z and I’m giddy like a school girl

im getting one of those cars this sunday.. i subbed..

Do you know how much power it’s making? Trying to work out wether too upgrade this engine or swap it out?

There are several of these Z engine rebuild videos but nobody ever mentions a performance cam. Do they even make them for these?

What’s the advantage or point of threading oil Gally plugs ? Disadvantages on nit doing it I guess, got my L28 N42 block n42 head going to shop this week..thanks

How do you get the wrinkle finish it looks like a bed liner. How Yougot it ?

I recently got handed the keys to my father in laws 82 2+2 non turbo really clean car low miles reason being his buddy in the late 80s ported the cylinders and put it back together I have no idea why they did that but now the cars seems to run great but soon as that 7th warm up injector shuts off the cars runs like its gutless sputtering about...... I've done forum research and have found nothing

Why do you leave the intake port rough but the exhaust port smooth?

My bad if this is redundant, but what was the purpose of the front and rear oil galley work you did?

excellent video, i have a question what side mirrors are you using ?

oh no the z garage link is down

any modifications for the l24 motor that are worthwhile?

Did you check the 2mm shaved head?

tell me why you do what you do.

Bore it to 90mm and get a diesel crank and L-14 rods and you'll have a 3.2liter
