Re: Re: CJ-5 Heater Fan Upgrade Questions
SnoMan,
I'll be honest, I wasn't paying too much attention as my Son was in the back
seat and I just wanted to get off the hi-way after I heard the Bang (I
didn't want to be stuck in the middle of a four lane with a child in the
back seat) I thing it was thru the carb, but not absolutely sure.

When it is through the carb it is usually (not always) from a leaning
out conditon. When mixture gets too lean it does not fire properly and
the mixuture is dumped into exhaust manifold where it starts to ignite
and then the flame travel back into cylinder and into intake during
valve overlap. You may have a weak pump or plugged filter that is
causing it to lean out under high demand periods. I sticking or burnt
valve can cause this to but if it is a burnt valve it would be
consistant. I have also seen a worn cam lobe cause this but it too was
also consistant and predictable.

Re: Re: Re: CJ-5 Heater Fan Upgrade Questions
Bad news !!!!! The shop did a block check ($75) and there is exhaust
getting into the cooling system. Not much, he's getting a hydrocarbon
reading in my radiator/coolant. Mechanic says it's probably not the head
gasket, but rather, a cracked head. That's gonna hurt.

Re: CJ-5 Heater Fan Upgrade Questions
Hmm...........
I think you are being fed a 'big' pile of BS!
(There is this really old scam that happens when folks that know nothing
come in with unknowns like yours. They put a squirt of oil in the
radiator and show you the 'test' results, then sell you a new engine.)
A slight hydrocarbon trace in a cooling system does not happen from a
big bang and stall.....
The head would have to be blown open or the headgasket blown right out
to cause the Bang/stall (it is seriously hard to stall a 350!) and for
the bang/stall to have caused that first, well.....
I don't buy it for a second....
You just had a bunch of unknown arms and tools all over the rear of the
engine around the firewall. I really would be suspecting a wire knocked
loose on the coil or distributor.
