No Compression

You could always pour marvel mystery oil down each of the cylinders as well. I've had super stuck rings only freed by marvel and nothing else. There is other underlying issues I can almost bet but lack of compression in that many cylinders seems like a timing chain issue to me. That or a seriously blown head gasket

if it jumped a tooth than yes the timing chain could cause some issues... not ZERO though...

here is my deal with oil... oil has a little bit of detergent in it, good for a clean engine and keeping it clean. ATF is cleaners and eats anything... goes after carbon like nobodies business...

once he gets it running and hot then he can pour down the carb and get the carbon off the valves and piston tops
