Nice to see so many GW enthusiasts, it helps with all the questions.
Just bought this 89 gl 1500 SE for $500.
It needs some work.
There is a lot of extra wires going nowhere, no mufflers and no radio but it starts and runs excellent.
Changed out the oil and filter and final drive oil.
Checked all fluids and topped up.
I compression tested and got 180 to 190 on all cylinders except #4.
That cylinder gave me 155 lbs.
Any ideas on possible reason?
Put new gas and half a can of SeaFoam in the tank.
I'm getting a bit of white smoke out of left bank exhaust but not a lot.
Hoping for a simple fix.
Nice to meet you all.
