JDM Imported Engines and problem solving help, got a bad engine

We paid for a JDM engine and and installer for wifes cousins 2003 Toyota Highlander 4 Cyclinder. Car was driven home, seemed perfect. Made a few short trips to get the DRIVE CYCLE ready for smog. Then I noticed dripping coming from passenger firewall side of this 4 cylinder engine. Called installer, he put on his lift, and decided that the engine had bad head gasket.

So we have a 90 day to get another engine...

So expense of taking out, and replacing with another.

How does one choose an engine among 3 or 4 sitting on the floor. They may not have starters , so you cant turn them over to check compression.

Any thoughts would be helpful

So we are sorta caught with the same JDM location for an exchange. And installer will give a little break for the next install

I guess I'm curious why a head gasket is a reason to get w whole new engine.

Did it overheat? If not ...

You want the cleanest engine.

If you can inspect it pull the plugs and examine.

Inspect the exhaust manifolds. Again you want the cleanest engine.

Pull the dipstick. Examine. Smell. Feel. You want the cleanest oil.

Inspect. Look for any use of silly puddy (silicone).

Will they give you any idea how much use any of these have had?

Also me and some friends have a container leaving Tokyo for Long Beach end of March if you need something. My friend Hu is a mechanic with a shop in Tokyo and is bilingual.

Long Beach is where my JDM location of purchase is by coincidence. Although I currently don't have good ratings for them, but that will be determined after car is back in service.

Had to look up "JDM". Assume it means Japanese domestic market.

Paying a mechanic to replace the head gasket might be more than the cost of the replacement engine. Not sure about the cost of parts alone without spending an hour on reading repair manuals and building parts lists.

Buy a borescope camera, pull the plugs. Look at the top of pistons and cylinder walls. A leak down test can partly simulate a compression test (metered high pressure air into the plug hole with both valves closed). The next step is more work and expense, but check the valve lash, and maybe timing chain and tensioner.

It does, but I often see it applied to any Japanese car company item, even if for the US market.

Ouch. I just scrapped a 2008 Honda CRV because the head gasket blew and the engine overheated, the head is probably warped, and I did not go around with the overhead cam and timing.

Is there no warranty on the engine? Why should you have to pay to remove/ reinstall their engine that failed?

Because that’s the way the sales contract reads. Pretty standard.

This is the issue with being the “general contractor”. If there’s an issue, the bogey is on your back.

We generally discourage people who want to supply parts. (Yes, we make a profit on parts sales.) But, if the part is wrong, or no good, the warranty is on us. We supply diagnostics and warranty labor. Customers rarely understand the reality that if there’s a problem, it’s on their dime, and they can get stuck between the supplier and installer…

Before my mechs retired, they had the same policy.

Yes they made a lot of money on parts, some more than others.

But they absolutely warranted their work and labor, so I was ok with that.

I never had an engine swap, but just replacing the alternator on my car was a huge project.






I am that Masked Man.

All you can do, is all you can do.

There’s trouble — it's time to play the sound of my people.

Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

I've been to the edge of the map, and there be monsters.

We are a government of laws, not men.

Everybody counts or nobody counts.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

We don’t do focus groups. They just ensure that you don’t offend anyone, and produce bland inoffensive products. —Sir Jonathan Ive

An armed society is a polite society.
And hope is a lousy defense.

You make me pull, I'll put you down.

I *love* SIGs. It's Glocks I hate.
