98 ranger 8plug 4cyl
this is going to sound silly but I need answers....
My BF has a 98 not sure of the Litres but its the 4 cyl motor with 8 plugs
his catalytic converter started to plug up and he is saying that caused the bearings in the lower end to go out???
can someone explain a little more clearly what happened?
I know bits and pieces on working on rides and open to learning...especially if the ride is gonna be in my yard any length of time...
he just got a used motor but we dont know its condition either but i am mainly wondering what went on inside his...

The 1998 has a 2.5L engine.
His catalytic converter started to plug up because the engine was not tuned properly.
The bearings int he lower end only fail due to a loss of lubrication. Thats what caused the engine to fail. The failing engine also ruined the catalytic converter, not the other way around. It is not possible for a plugged converter to cause bearing failure.
The best prevention for such problems is to use a good quality oil, with a good quality oil filter, and to change the oil when it starts to get dirty, and to make sure the oil level is correctly maintained. Also cooling system maintenance is critical, if the cooling is not maintained, the head gasket can fail. If antifreeze gets into the oil, it can cause bearing failure. Also if antifreeze gets into the combustion chambers, if can foul and plug a catalytic converter.

OK thats kinda what i was wondering .... He maintained it but it was given to him by his mom who has had an issue with poor maintenance and health issues.... aboout 6mos befor it happened I put a tune up on it and he said it ran better than it ever had ... the plugs i pulled out were so far out of gap I am assuming now the damage had already been done... bad thing is last tune up was done in Southern Il at a shop and one of the plug wires wasn't completely on either.
