I drive my 4Runner almost every day and most days I drive its 70-100 miles a day. I don't baby it and often kick it pretty hard when I need to pass someone on the freeway.

I have heard the 96 motors had problem with hg... but the failure was coolant or oil leaking out from the head. Not into it.

The recall in 4Runners was for '96 and early build '97 5VZFE's. My 4Runner was built in July of '97. After calling to confirm my VIN, it wasn't included in the recall. No problems to date.
I believe the recall was for all 5VZFE's (4Runner, Tacoma, T-100) from inception to early build '97's.

According to my documents from the original owner, my super early '96 (built Dec. 1995) had the head gaskets replaced at 28K miles because they were notably leaking coolant on the exhaust manifolds.
I would say if they didn't fail in the first 50-75K miles, then you're probably not going to have any dramatic failure down the road.

Did your engine overheat prior to HG Failure?:No
I have heard that a common cause of HG failure in the earlier 3rd gen models is commonly due to the exhaust manifold and cat. The y-pipe connects behind the engine along the seam between heads and block. If the cat craps out, there is insuficient dispursing of exhaust gas (aka heat build up) right along the the location of the head gasket. I believe it because my runners gasket blew on my rear most cylinders.

I also have a Toyota 7M motor that BHG'ed. Just finished putting it back together. The T100 was babied with full synthetic oil every 4-5k mi. This was supposed to be my "old reliable" while fixing the supra. Now I put all my eggs in one basket, toyota basket, and have no ride at all.

lol, notorious b/c boost pressure causing most of the BHG ...
and now the same rep can be had for the 5VZ.
The 7M lasted to 200,000 miles while being pushed rather hard before BHG.
The 5VZ made it to 11X,000 mi but was babied. Maybe it's time to push the 5VZ.
I didn't see any recalls on the 7M though, (maybe I somehow missed them) but I see quite a few posts stating ppl got their 5VZ HGs replaced as part of a limited recall campaign.
