Blown Head Gasket Symptoms!

chash360 · 06-11-2007, 07:26 PM

I got really scared the first time I flushed the sytem after my first valve job, and thought oh-no! I missed something big, or that the block was cracked internally somewhere, but after a couple of flushes it was all good.

FYI: citra-safe or equivalent type of citrus solvent works amazingly well on any grease or petroleum based deposits, even hard black carbon deposits and most non-acrylic or non-epoxy adhesives, etc, without attacking seals too bad. Simple Green is a good one too, and being vegatable based they are not a hassle to handle, or danger to your health, enviromentally sound, etc. (they work good as hand and clothes cleaners too)

Thanks for the advice I got the head off and went to the machine shop. I just got it back yesterday, I going to put arp stud in and im having trouble finding them. Ebay which is where i got the gasket set off of doesnt have any listings for a 7mge. All they have it studs for the 7mgte, arent they the same as the 7mge. If not can someone give me a website where I could get them.

The 7mge should be the same set as 7mgte, the t means turbo. The head bolts and manifold studs should be the same. You may end up with 4 extra bolt-nut sets for the turbo, but I don't remember those actually being in the kit. The best gaskets for this motor in my opinion are available from NAPA (its about the only thing I get from NAPA for imports). They are laminated metal-graphite with a teflon coating. Not the 'paper compound' types, even if they have the cylinder and jacket beads (like felpro's), these will eventually disintegrate.

does anyone know where i can get the special tool to torque the nuts back onto the head

DONT !
do not put a cheap $50 head gasket from felpro,,,
Get yourself a Titan or HKS, or cometic metal 2.0 mm gasket.
Pretty much guaranteed not to blow !

Hi , Im planning on buying an 87 non turbo supra and the guy that wants to sell it says that its overheating, and blowing coolant out the exhaust could this be because of a bad head and gasket , i need help figuring it out

evosupra · 07-21-2009, 03:53 PM

Hey Bud, if it is blowing coolant out of the exhaust, it is far more than just a head gasket ! That head is warped bad ! Is it just white smoke or dripping out? The turbo might be messed up too.
How much is he asking for it? I have a stage 2 port polished head if you need one ! I am only asking $150 plus shipping.
