question about lifter tapping

[Brady Moffatt]

In my JT code '86 4kq with 319,000km, I use Mobil 1 10W30 in winter, Mobil
115W50 in summer, although this past year it was 10W30 all year. No
problems, occasional VERY minimal lifter tick. Oil consumption of maybe 1
litre every 20,000km.

To say 10W30 isn't a good viscosity for I5 engines is a little too much of a
generalization. It depends where you live.

Yes - the MC cam is a bit more aggressive, and makes a nice little upgrade
in the 4kq KX in my experience.

I concur with the opinion that 10W-30 is not a good viscosity range for the
I5 engines, especially the older ones.  I tend to use 20W50 Castrol, maybe
10W40 in much colder weather has provided good results.  I have found some
generic brands of even 20W50 tend to "thin out" quickly.  I swear by the
Castrol 5W50 Syntec for my positive experience over the years, and when
trying something else - well, not so positive.

YMMV.
