Default piston rod thrower

my stock 1.3l has had a tendency to throw a piston rod out the side of the engine block. this time i was lucky enough to stop before that happend. are these engines known for that?

another question, would a 2.4L fuel injected jeep engine fit in the samurai? and would the jeep trans fit as well or do they make an adapter so you can still use the stock trans?

No they're not - and since you say yours "has had a tendency", I have to assume it's happened more than once.

The only time I've seen one of these throw a rod it was a race engine on which the engine builder took a phone call whilst assembling the bottom end and forgot to torque the rod bolts (as a result of which he will no longer take phone calls whilst working).

I'm curious - were any parts re-used in between engines? Were the engines new, was the first one the original? What oil were you running?

Just trying to see if there is a common factor between the failures.

the first time it happened it was the origanal engine. the only part i kept from it was the valve cover which made its way on to my current engine. the engine i replaced it with was a used engine and before i put it in i went through and retorqued and tightened everything to specs. and for both engines i was running 20w-50 oil which was making it run smoother.

Well - I don't see the valve cover as a potential cause of a thrown rod.

Which rod was it? Same one on both engines?

I don't quite like the sound of 20w50 making things run smoother - there may have been other issues (perhaps excessive bearing clearance), the recommended oil in these engines for most applications is a 10w30, going down to a 0w30 for cold climates, and a 10w40 for hot ones.

I'm in the tropics and see "summer" weather all year round and I'd never run a 20w50 in one of these.

Edit.

Do you know the history of the original engine (have you had it from new ?) If I recall correctly there is an oil passage from the front main bearing to the head, and there should be a restrictor in the head and I believe if it's not there you can get low oil pressure on the front main which can then lead to low oil pressure on the #1 rod - I haven't experienced this personally, but I've been told about it.
