do not pour anything foreign into your car. front cover
oil leaks/seepage is common on these cars. do a search
and you will be inundated with volumes of suggestions
to fix it. choose what is applicable.

zero oil pressure while driving should be a concern.
zero pressure while idling is also a concern but remember
oil pressure normally drops when oil is hot and circulating
in your system. below 1 bar is not uncommon.

i would suggest using a heavier oil and observe your
guage, before tearing your car apart. cheers and welcome!
