80 series Land Cruiser Valvetrain pictures with 450k miles

[Cruisin30]

Hey everyone,

I was wondering in your guys opinion how does the motor look for its age!

 

[Cruisin30]

Thinking of throwing some Valvoline Restore and Protect in there but not sure if it’s needed.

What do you normally run 5w40? 15w40?

 

[slacktide_bitog]

Looks good

 

[CleanSump]

Top end looks really good, especially for the mileage.
Does it burn much or any oil? The Restore & Protect would make sure the pistons and oil rings are as clean as under the valve cover.

Why so dry? Did you wipe it down?

 

[Cruisin30]

Thank you, doesn’t burn any oil surprisingly.

I’ve been using Mobil 15w50 actually!

That looks fantastic for the age. I'd go for the Restore and Protect for 3 or 4 oil changes in a row. Can't hurt.

Looks great. Keep doing exactly what you've been doing, don't change a thing.

Looks fabulous for the very high mileage. How many of those miles have been with m1 15w-50, perhaps its been lightly cleaning since mobil oils tend to do that.

That 80 series engine looks fantastic! Valvoline Restore and Protect definitely won't hurt but that looks great as it is

Do you know the engines maintenance history back to 96?

Yes, 1st oil change was done back in 96 with 20w50 3k mile intervals. 20w50 up until 300k, I think it was mostly a mix of Kendall oil back in the day and Mobil 1. Then it’s been on a mix of 5w40 and 15w50 since then.

It’s whole life essentially! 20w50 as well up until 300k

Fantastic.. Thanks!

I love the thought of thick + 3k intervals. Have you compression tested it and does it burn any oil? I hope the bores still show good crosshatching too.

Impressively clean for the mileage.

 

[cheech279]

You gotta give us a pic of the Cruiser itself!

 

[SC Maintenance]

Looks great.

Given it doesn't burn any oil either why on earth would you change anything your doing now?
