1990 Porsche 911 Problems
Check Engine Light illumination and performance issues can be caused by oxygen sensor faults.
The brake warning display and warning gong can activate, typically after the first start of the day. The warning light/gong might stop after idling for a short time. This fault is usually caused by low stored hydraulic pressure due to a failed high pressure accumulator.
An external fluid leak may develop at the pressure switch; fluid will be evident in the trunk and the reservoir level will drop.
Over time, the engine can leak oil at various locations. Early-production vehicles require engine disassembly and modification to resolve leaks at the cylinder heads, oil return tubes, valve covers, timing cover, chain housings, case through bolts, and lines to/from the oil cooler.

1990 Porsche 911 Reviews
A real success story for Porsche.The 911 line up seemed to get better with each year.This is the "real" Porsche design philosophy...rear engine , air cooled.A great performer , the engine is as strong as they come.Service cost can be high.For example valves require manual adjustment , dual ignition has twelve spark plugs...every 15,000 mile service.Plus twelve quarts of synthetic oil every 7,500 miles.Unfortunately deferred maintenance will cost in the long run.A few oil leaks remain to be fixed , but thats on the list.
All in all a real tour de force from concept to build.
