Greetings All,
I was told by a mechanic that my SD33 non-turbo in my MQ is back-pressuring.
I no not entirely sure what that means, but exhaust gasses are coming through the oil filer cap when open, the dipstick tube when the stick is removed and the breather on the engine block, just behind the front left wheel
so I figure that the piston rings are worn and exhaust gasses are entering the crankshaft area as well as the top of the head where the camshaft is
the engine is under-powered, but working
I am trying to evaluate what my repair options are:
do I need to buy the entire rebuild kit? i.e the ones with all teh gaskets and pistons
the vehicle is a weekend runner only as is parked most of the time.
I will be weighing the SD33 rebuild cost vs engine swap cost.
the sd33 is an old engine and hp figures would be lower than a newer model diesel engine (e.g TD27, RD28). We don't get RD30 locally so its not an option). Tthen I would have to do a 24-12V conversion
so I dont want to spend the same (or close) amount of $ to rebuild teh sd33 when a more powerful, newer diesel engine would cost the same
as much as I would like to keep her original, if a different engine configuration means more power, more reliability, easier maintenance, then I would go that route
I have also seen a couple Chev 350 powered Patrols that are impressive, but I figure that those conversions would be costly and more complicated
I rather invest $ in some diff lockers and a winch, so engine rebuild cost isn't looking well for my pockets, since locker and a winch don't help out offroad if the engine wont take the truck there
I would really rather repair teh sd33, but need some options, that engine is pretty low power right now
