Thank You for posting the link to this 2006 Toyota Camry 2az-fe repair. I have a 2003 Camry with the same engine and hope that I can avoid doing this repair. They just dont make them like they used to.

I wonder if owners can avoid this problem by doing some preventive maintenance.... like keeping the coolant level up or something simple.

What repair is this. Link doesn't work.

This link is for repairing the threads in the block for the head bolts that are being pulled right out on some of the earlier 2AZ 4 cylinder engines. It envolves using helicoil inserts.

I just tried the link and it worked for me. If you are interested you may want to try the link again.

I see this on about 75% of the 4cyl Camry engines. The threads of the block come with it.
Also happens on honda/Acura 3.2 v6 engines as well as caddy Northstar engines.
I don't recommend the inserts myself but it is proven to work if done properly.

What is your recommendation for a fix?

Used engine or new short block

The above fix is meant for home mechanics, more so than would be an engine replacement or rebuild. I think you're right on what is the best fix.

I'm not sure if a used engine would be the best solution as the block headbolt threads could let go shortly after engine replacement. I have read a post on a different fourm to someone who had this happen to them shortly after they installed a used replacement engine.

As far as a new block goes I suppose that would be worth it if the new block addressed the previous design flaw with the block headbolt threads.
