The hollow push rods get oil to the rockers and push rod ends through the l
ifters.Don't think cooling was the issue there.

Subject: Re: JabiruEngine-List: SI 8
I am not trying to be a wise guy here, but I would just note that the Jabi
ru is not an oil cooled engine; it is an air cooled engine. So fussing ab
out trying to cool the oil some way is possibly looking at the wrong issue.
Also, looking at Ly-cons is not helpful. There is some way to flow air
better, even while taxiing. Beware of "fixes" for problems that are best
solved by airflow. That includes the water cooled heads, "better" carbs
and huge oil coolers.
Just my opinion

I have been talking off line with one of our members and he brought up the
subject of the hollow push rods. I pulled the SI 8 and read through it and
call
my dealer. It would cost me about 1K to install the hollow pushrods and
lifters, plus it would put me down for a while. I'm not sure of the benefi
t.
Lycoming and Cont has been doing it that way for fifty-sixty years. It mak
e
sense to use the oil to take away the heat from the heads.
Has anybody installed the hollow push rods.
I'm just coming up to five hours on my engine and still battling the heatin
g
problem. I'm a 1/2" from the ends of the runway and have to shut the engin
e off
at the ends as the temp come up to 302 by the time I get there and the oil
temp
are below 104.
