Last night I tried my luck at solving the major oil leak coming from somewhere on the passenger side of the motor. If anyone has worked on a 914, there is not much room to diagnose problems especially when that large v8 is stuffed in there.
The one benefit is that they do not make a more simple engine than a Chevy 350. Any shade tree mechanic can fix most problems, and I had seen similar leaking problem from that side of the motor coming from the fuel pump area. If this was sitting in the front of a pickup truck, or a large 60's sedan then I would not need the miracle of "Tracer UV oil dye"! Thank god for modern technology!
I simple added a little less than an ounce of this dye into the motor and fired up the engine with the car on jack stands. I let it run for 5 minutes until I saw a pool of oil dripping on the drip pan.
Next I put a black light bulb in my shop light and climbed under that car. POW! The dye glows a neon yellow color where fresh oil is leaking. From under the engine I saw the glowing yellow dye dripping from the bottom of the timing chain cover. I followed this yellow line up one side of the cover, up past the water pump outlets and out of sight.
Using my "mirror on a pole" tool, I followed the yellow line (struggling with the little space the whole time) up to the top of the motor where I saw a brilliant splash of yellow sitting right below the intake manifold.
Next I climbed out from under that car and used a bright work light to spot that yellow area and found the location of the oil pressure gauge sending unit!!
How easy!! What a relief!!
After dropping the car back on the ground, I pulled the sending unit out, applied new thread tape, installed and tightened down all connectors.
FIXED!!
