i have an 88 rx and a couple of mech. told me the motor is blown and one of them recomended that i do this block weld trick? and i all i could come up with is block sealer...does anyone know anything about that stuff?

 

Interesting. JB WELD! :| Is your block like, cracked or something? Usually when a rotary goes, it's the apex seals......where you'd just tear the motor down, and replace the apex seals...and whatever else is bad inside.

 

i think those mechanics need fired

 

IMNSHO, waste of time.
You're trying to band-aid something that really needs a rebuild and replacement of the bad parts.

he said thw water seals were blown and i could pour this block sealer stuff in the radiator and it would be a temp. fix

 

it might be a temp fix but it will makes things worse down the road. Best to fix it right now than fix a bigger mess later.

 

just rebuild it. your trying to band aid a shotgun to the chest.

 

...and you just ruined your radiator, water pump, and heater core, at minimum...

I disagree. I did it and it worked for me. search the forums for it. I took my thermostat out and followed the directions to a t. You have to do it like 3 times, but now no more pissing coolant on the ground and buzzer going off every ~100 miles. The motor goes from something else, then I will deal with the 'mess' later.

 

My buddy did it to his GXL and he got a year or two more out of it.... But it's all types of fucked up now.

 

this will NEVER work!!

it maybe a solution for some leaking radiator, but no way for the water seals! those areas are highly stressed ba both temperature and pressure!
not to mention what RETed stated very truly!

rebuild it!!

 

The block sealer is ony a last resort option if you lose a bit of water seal and then must, absoutely-no-question-about-it drive the car somewhere (track event, hospital to give birth, running from the mob, etc.). It does work, sometimes in the long term, but coates the entire cooling system in crap. It can clog the radiatior, heater core (have fun replacing that!), etc. etc. It should NOT be used if you intend on rebuilding the engine because the sealer is a royal pain in the butt to remove from the water jacket.

 

I like how you use "giving birth" and "track event" in the same breath.
