FJ60 straight 6 engines?

[Ingrid Biedron]

My 1984 FJ60 Toyota Land Cruiser is burning/leaking
about one quart of oil/500 miles and only getting
~10 mpg. Therefore, I think I might be looking
for a new engine soon. Any suggestions
on places to search for straight 6 engines
for sale that would be compatible with a
1984 FJ60?

Thank you.

10 mpg is in the ballpark of what to expect from a 2F. Mine is well tuned with a good running carb and I might get 15 mpg on a flat stretch of highway keeping it at at 55 mph. Chances are a leak can be fixed without too much pain, it could be as simple as an oil pan gasket. If your engine is burning oil, that's a more serious problem.

Do not make the leap to replacing the engine until you know that you need to. The symptoms you mention are likely very minor problems.

Do you get any blue smoke from the tail pipe? if it smokes a little at start up and then quits, its probably just bad valve seals, which are MUCH cheaper than getting a new engine. My FJ40 leaked a quart a week when i first bought it.. replaced some seals and it was good to go.

what is your location?

As said above don't jump to a solution until you know what the problem is. The 2F engine is a very robust engine and generally has a long service life. You could just have leaks that can be fixed or your valve seals could be leaking into the cylinders, which is a pretty straightforward repair (cheaper than installing a used engine). There could be lots of causes for low-ish gas mileage (tune up, valve adjustment, emissions component failure, etc.), but as Seth says above, 10 mpg isn't that low for these engines.

If your engine is shot, there are generally three ways to go:

(1) rebuild or replace with the toyota 2F
(2) do a V8 gasoline engine swap
(3) do a diesel conversion

Depending on the final solutions these options above are ranked for easiest/cheapest (1) to most complex/expensive (3). But you will get the best fuel consumption with the diesel conversion.

Run a vaccum and compression test first. Testers can be rented at parts stores. MIke
