is it true?
i have head plenty of hear-say that if there is an exaust leak on a rotory engine, a massive loss of compression will b the end result. i also need help to determine wut EXACTLY is wrong with my 86 rx7. it seems to act like it will not crank for ANYTHING. and it DOES have an exaust leak. the starting problem started the day the exaust leak happened. is this purly coincidence? HELP!!!!

Start by doing a compression check.

First you said that it doesnt crank, then you said it sounds like no compression. So if you meant that it doesnt start, then do the compression test and hopefully you can rule that out.

Now I dont know if I am right or not (could be coincidence) but when I got my RX-7 it had 1# no compression in the rear rotor, 2# clogged cat, 3# exaust leak. It is my understanding that the clogged cat cooked the rear seals (which was where the problem was) and I also understand that a clog in the exaust will cause the exaust gases to look for a different way out, causing a leak.
