you got it.
factors are ............
could be a really bad lifter,
could be a mis-adjusted rocker arm screw.
and .........have only seen this once, and you'd think it would be there
cold too - but a trashed up rocker arm screw or rocker arm.
but i would always treat the oil - with Hyduralic Lifter
Treatment...........CD-2 is one I like -yellow bottle.
also...............I have used a million gallons of Castro GTX 20W50 -
when I got into Diesels in 1992 in Sausalito Ca I got turned on to
Chevron Delo 15W40 - some salesman even said it stood for 'diesel engine
lubricating oil' - who knows about that.
but now..........for a conventional oil, for well broken in engines ,
for normal temps, like above frezing........i never ever use anything
but Chevron Delo 15W 40.
I might use Mobile 1 15W50 .........
and diesel people can use 'real' dedicated diesel oils.........
but i've even tried to make an engine 'smoother and quieter' by going
from Chevron Delo 15W40 to Castol GTX 20W50 - i never did that again.
it was not better.
I 'might' sometimes on a very old and tired engine use Engine
Restore........but that's somethign with years and years and hundreds of
thousands of miels on it like my 1970 Mercedes gas sedan.
but if the vanagon was in my shop.............as a paying job- i'd go
through the rocker arm adjustment.
when you get to a bad lifter, or one not pumped up right, it's obvious.
when that happens, all you can do is fake the adjsutment and not make it
too tight..........
and run the engine and treat the oil and see what happens.
or replace that lifter.
I always find several things wrong anyway that people didn't even know
about.
People always think it's 'one thing' - in my world...........
it's commonly 4 half things and one solid thing.
Course everyone has their own ideas about engine oil- it's like religion
that way.
