Default UIM Replacement

Need to replace LIM gaskets due to oil leaks. Also have had to add coolant a few times
over the past year. Need to know whats the best UIM to use & what all gasket that I
might need that don't come with gasket set.


Thanks in advance

The standard run should be the below. Injector o rings, thermostat and valve cover gaskets are usually optional. The best kit at the moment appears to be the APN which is sleeved with reduced diameter stovepipes.
