ive been hearin 2 differnet stories so correct me if im wrong...is there a head gasket in a 87 n/a rx7 and if there is what are the signs of it being blown??

 

omg....no....rx7's dont have pistons, therefore no valvetrain, therefore no head, therefore no gasket, therefore no signs of it being blown therefore you should go to www.howstuffworks.com and therefore you should look up piston engines and therefoere you should look up rotary engines and therefore you might understand wherefore this stuff works. Therefore you may get lucky and it may therefore work out in the end. BTW put on the flamesuit. Therefore you dont get burned.

 

The rx7 equivalent are coolant o-rings. when theys go, it is simalar to what happens in a pistion engine.

 

lol oh my gawd zan. that was great!!

rotflmao

 

thnx thnx, sorry but i had to....i was trying my best to get the point across without opening up and letting loose....

 

um yeah, nice zan, be nicer to the kid, he doesnt know.

no heads, no valves. Only coolant seals.

 

The seal between combustion gasses & water jacket is a rubber O-ring in a groove all the way around the aluminum housing.
If it leaks you get coolant in the combustion chamber, just like a blown head gasket in a piston engine.

I have had this happen, and was able to patch it with radiator stop leak.
I caught it early, before there was too much erosion of the O-ring.

The short version:
Hard to start, catches & sputters, blows white smoke, then clears up & runs OK.
To fix:
Good coolant flush, add half the stop leak, idle warm up to full temp, shut off & cool down cold, (repeat)

Do a search under "block weld".
Many have had good luck with that product & there is a good write up on the forum using it.
