i overheated my engine yesterday by the hose from the thermowax valve to the block busted....it stalled on its own....i then quickly shut it down.....

what ive done so far.....a total unflood method and nothing...it wont crank.....i even did the oil in the trailer hole thing..still no turn over...any ideas?

 

If it won't CRANK then the engine is siezed, probably from overheaing. Apex seals are the least of your concerns at this point.

 

this mean a new engine or what?

 

Have you done a comression test yet? Stop guessing and find out for sure!

 

how do i hook one up....what should it read

 

Do a search for "compression test". It contains instructions on modifying a regular compression guage to work with the rotary. Long story short, you remove the little valve in the guage and connect it in place of one of the leading spark plugs...You are looking for 3 even bounces of 70PSI or greater per rotor.

 

look thru the exaust ports with a good flashlight. You can also run your fingers on the seals. You might also want to check if it bounces back but dont push too hard because you dont want loose the strength of the apex seals springs.

Compression test is the best though!..Mazda will do it for you for about a 100bucks!

 

how do you do a compression test on an engione that is seized?
