hunky

G'day all.

I'm the proud owner of an old '90s EA falcon manual 5 speed.
It runs on LPG and I love it.

Could someone give me some advice?

The car in total has done about 550,000 kms but the body is fairly straight.
Is it worth putting a new engine in this old girl?
Have just spent a couple of grand on new radiator water pump, front disc rotors etc.
Also
The engine seems to sound like it's not running on all 6 cylinders when it warms up and may be on the way out.
Under the inlet manifold there is an 1cm dia orange hose which plugs into a black right angled connector-into the manifold, and is leaking a bit of coolant. These 2 problems might be related???
Just thought I'd throw it out there for some insight from someone who may have the same dilemma.
Cheers @ Beers.
