I'll second that. My '87 5KCSTQ had just 50k miles on the clock when I
bought it but was already giving me some minor lifter tap for up to a minute
or so after starting. However, the oil history of the car before I owned it
was sketchy, and it hadn't been driven much in the past 2-3 months before I
got it. I put in some MMOil, ran it for about 250 miles, then I changed out
the filter with the *dealer specified* unit with anti-drainback valve and
changed to Mobil 1 10w-30. That did the trick: any lifter tap I get now
lasts for about three seconds upon startup, max.
On the subject of oil, without opening the entire can of worms up for a big
fight, I found this article very interesting the other day while reading
about a fellow Lister's adventure with his 1.8T sludge problem. I found
this to be a pretty interesting article (it is the second link):
This second link has intrigued me. I'm thinking of adding a dedicated
oil-pressure gauge to the 5KCSTQ and mounting it in the ashtray area, along
with maybe a voltmeter. After that, I'm going to take some pressure
readings and give the Mobil 1 5W-30 a try.
SIDE QUESTION: Has anyone ever plumbed in a Sunpro or VDO oil pressure
gauge (I'd prefer electrical to mechanical) on a late-80s MC1 Turbo engine?
I know they have two oil pressure switches, just to trigger the autocheck
system, and I'd like to preserve those while also getting a gauge readout.
Any BTDTs or recommendations?
