Builds LX450 where to start! (1 Viewer)

I know in San Antonio, Kotzur Racing heads has experience with 1UZFE heads. I don't know the name of the shop, I got the impression from the EMS guys that it was a one man shop that has been doing heads for years and years and that only took on projects from people he knew.

It's Brooks Elliott Cylinder Heads. He is the best head guy in all of Texas that I've had the pleasure of with. But, he may turn you away if you're not an old established customer of his, based on his workload. He has heads sent to him from all over the country these days.

I haven't seen the actual work Kotzur does yet, but so far what I can tell you about Kotzur is that they're beyond slow and do not get parts back to you in anywhere near a reasonable amount of time.

Looks good Scott! Did you go with new bearings and rings? IMHO if you are that far you might as well.

I googled Kotzur and found a lot of complaints about how slow they are on getting stuff done and back.

I guess as I get close to needing a machine shop Ill search other forums and who else is around with good reviews.

Concrete,

I don't think I am going to do bearings and rings.... The engine is fairly low mileage, 139K, it has been running synthetic for the last 30k miles, and I don't see a lot of oil use. According to Toyota's life cycle plan for the 1FZFE, they should be good for another 160k, lol.

OK, but it's cheap insurance for an even longer life! Did you plastigauge to check tolerances?

 

[scottryana]

The oil pan hasn't even been dropped yet so no plastigauge.

 

[scottryana]

Yeah I think it's just a matter of where do you stop? Remember this was all just "Preventative Maintenance". The truck ran great, I just wanted to do the head gasket so I no longer had to worry about anything on long trips.

You could inspect the bearings for signs of wear and scuff marks. If none are found on the cap side you can just reassemble and not worry about it.

I wouldn't bother with plastigauge if there are no signs of scuffing.

Thanks for the sanity check, I will recommend it to the shop. I think they were going to try and work on it the rest of the week and get it back to me soon.

Now you got me thinking, my rig has 129,xxx. Anyone have shop recommedations for head work here in CA?

Parts are cleaning up well.

Valve Cover

Valve cover cleaned up before media blasting and powder coating.

Nice.

Is PC merely aesthetics or is there an intended heat dissipation purpose?

Don't get sucked in! Put the money away for when you actually need it.

The powder coat on the Valve Cover is just aesthetics. It will be much easier to clean up than the cast aluminum.

I thought about several heat coating options, for the valve cover, intake plenums, exhaust manifolds, exhaust shields, etc.

After talking to EMS and thinking about it, thermal coating the valve cover, and intake plenums might actually retain more heat? The intake plenums are opposite the exhaust and don't see those high temps, so I am just going to do a ceramic coating on the exhaust manifolds, and exhaust shields, and I still might vent the hood, not sure on that yet.

Nice.
