The fact that you are getting lifter clatter along with the oil pressure
light indicates that you indeed have an oil pressure problem. Since this is
an older engine with possibly an unknown maintenance history and a lot of
down time it is possible that the oil inlet screen is getting block with
carbon and other debris including silicone from that head gasket job. I have
seen a number of 19 develop this issue, some with well under 100K. This is
elusive as after shut down the stuff falls off and everything will be normal
even during oil pressure testing. Normal driving sloshing etc. will make the
stuff suck up to the screen and block it again.
The 1.9 is also notorious for the main and cam bearing journals wiping out.
An oil pressure gauge will show this as soon as the engine warms up. Has
anyone serviced the oil pump? The wrong cover gasket will also cause oil
pressure problems.
Now for the big question, how is the oil level? Since it is recovering after
a few miles of low speed driving it could be the oil is overheating. The
most common cause of oil over heating on the Waterboxer is overfilling. The
top mark is not the full mark. It is the maximum do not ever exceed no
matter what mark. 4.5 quarts with filter at oil change time is plenty. Oil
will stay cooler near the lower mark.

Subject: What's wrong with my 1.9 WBX engine?
My engine recently developed a problem I can not fix. It is a 85 Vanagon
with a 1.9 WBX engine with 140k miles. There was work done to the cylinder
head gasket about 10 years ago. It runs very well still. I made a 200 miles
trip yesterday and everything appeared OK except this problem.
Every time I got off a freeway and came to a red light the oil light would
either blink or turn on steadily. Continue to drive a few blocks the symptom
would go away. A few times one or more of hydraulic lifters would collapse
and make clapping noise. They would recover if continued driving for a a
minute. Temp gauge showed normal. There was no coolant leak or anything. It
ran absolutely no problem if drove back on to freeway. In fact it ran very
well with plenty of power yesterday during the 200 mile trip.
Is it developing a serious problem now? I am running 10w40 oil. But changing
to 20w50 made no difference. I have had two oil filter changes already. No
change. I am not ready to give up this engine at only 140k miles. I don't
think it is an oil pressure sensor issue. At one time I was in a stop and go
situation for a while the oil light came on. So it does not have to be
driven on the freeway to have the problem.
This engine has been very reliable with no problems for the past 10 years. I
don't drive it much but do occasionally took it to trips of a couple of
hundred miles. Am I dealing with an engine that is ready to quit? Thanks for
any suggestions.
