Aluminum head


Ya I dunno...probably the rare factor... I have no interest in it. I figure after grinding mine to clear the pistons mines good enough.
 

I remember when aluminum blocks and heads came into vogue, and how it made my elderly machinist mentors roll their eyes. For starters, at that time planing an aluminum head was exactly double the cost.

Aluminum blocks I consider disposable engines.
None for me thanks.
 
I don't see much benefit over cast iron. Aluminum
expands and contracts at a much different rate than
cast iron,thus more incidence of blown gaskets. My
Toyota truck has had problems several times in the
300,000+ miles it has,and I've had to put a .020
shim underneath the gasket,as last time,the
compression was 185psi. lha
 
The advantage to the aluminum aftermarket heads was higher compression. But he lost me at "It needs to be serviced"!

HOW do you "service" a flathead cylinder head... change it's oil?

ight wonder what "needs a little bit of repair" means, too?
 
I sent a message and asked about the repair,

note he says it has been repaired, not needs be.

his resposne "if you are looking at the front it is the top left corner"

Looking at the first pic looks like the top left corner isnt as round as the other 3. I think Farmer Dan has an aluminum head on his?

That would mean no modern Toyota, Lexus, Honda, Nissan, Infiniti, Jaguar, Mercedes, Audi, BMW, Porsche, Rolls Royce, or Corvette for you. I am sure that list is not exhaustive and all use very highly regarded aluminum block engines. We have come a long way from 1970's Vega technology ;-)

thats what I was thinking, dont think he meant front of head, but first pic. I sent him another message asking what servicing it might need. waiting for reply.

debating if i want to bid or not...

just like im sure when tractors first came out, elderly farmers using horses rolled their eyes and said no thanks.

times change. modern aluminum heads/blocks > cast.

You're probably right and as TOH pointed out, "we've come a long way since the Vega."

In fact, it was the Vega, Colt, Cricket and Aspen that the machinists told me to avoid.
 

Don't forget my Renault Alliance.

When I bought it used in 1982, a mechanic buddy of mine told me to always carry a razor blade and a screw driver.

I asked why?

He said " when the head warps, use the razor blade to scrape off your Inspection and Registration stickers and the screw driver to remove the license plates and leave the car where it died.

2 Years later I left it under the Verrazano Narrows Bridge
