Are most of the coolant ports supposed to be blocked by the head gasket on the FJ62 (3fe) engine?

Asked by webrown43 Sep 17, 2014 at 02:10 PM about the 1988 Toyota Land Cruiser

Question type: Maintenance & Repair

I pulled the head on my 88 FJ62 and had it rebuilt.  I noticed that the new head gasket I
ordered was a bit different than the one I pulled off.  On checking, the old one appears to
be for a FJ 60 series engine.  However both gaskets block most of the coolant ports.  The
new gasket blocks two additional ports than the old one.  My old cylinder head was
cracked so had to get a different core to have rebuilt.  If the old one cracked with fewer
coolant ports covered, wouldn't a head gasket that covers even more ports just lead to
more cracking?

On closer inspection, my 62 series 88 Cruiser had the wrong head gasket on it. The old one was for a 60 series. And I suspect that the reason my cylinder head was cracked was that the 60 series head tasked does indeed block coolant ports in the 62 series head. Oddly, both series head gaskets block more ports in the head than are open. Apparently not all the "holes" in the head have to do with coolant flow. Anyway the right head gasket is installed and seems to be working fine.
