Im doing all the reasearch possible on the 2.3 now cause im soon to be the one under the hood.

Ive had this cool write up for some time now and think it has pretty good alternatives for tubo head gaskets.

Holy ! That is some deep stuff! sounds like some pretty good experiments, however, this car will not ever see more than 20 psi, well, untill I decide I can just blow it for the hell of it. I will say that is some bad stuff though because My dad and brother is a big fan of the Z cars and I do plan on building one for myself one day. Of coarse with some boost.

Well I got the head off, have a look.





This is between 1 and 2





This is between 3 and 4.
With 1-2 blown so badly, and 3-4 about to let go, what was the problem? Not telling me that came from just a couple of 7 lb pulls. Block is unhurt btw.

If it was the FP gasket in the set, it is the 8993, which is a decent gasket, and the one you should use if you haven't had the block/head checked, machined for flatness.  If you use the 1035 without making sure the block/head are perfectly flat, you WILL have issues.

If it popped @ only a couple "7psi pulls" there is something else wrong.  Take the time to check the head to make sure it's flat, clean everything very well.
Those comb chambers are pretty black.  How rich is thing running?

It really wasnt rich untill after I blew the gasket. After that I had to drive it about five miles, then had it started again to get it pulled into the shop. Keep in mind, I did get this one super hot once. Hole in the radiator and it pegged and died, got it cooled down and then drove it. New radiator installed and it was good. This was the first time this thing seen boost since it was hot. That could be a huge factor. I did double check and it is an 8993 hg, and just using a strait edge, the head and block look good. Looking back, what hapened to the pinto and one ranger was the waterpumps going out that started all the problems in the first place. I used a 6 in. sanding block when I cleaned it the first time, working in an x patern kinda like body work, looking for variation. it all looked good, and you can see the original machine marks. I also took note today that on the block I can see the defined circles from the O ring on the hg. Odd thing is with this 8993, you have a solid metal  on the block side, and rings on the gead side of the gasket, Is this the same as what was stock on this little guy? What do you think on the overheat? will it kill a brand new hg?

Well i got the head back on and took it out for some driving, Car seems to be all good at about 15 psi. I did however have a couple other issues that have to be taken care of. High ide wont stop, and iot is shifting really late, Will start a new thread after looking into it.
