Hi all,
I've got an interesting issue and wanted to get a second opinion on something.
So first off, I have a 1991 RRC that I got from a coworker. He bought it in 2016 and left it in our company parking lot for 2 years, where it just sat until I got the keys and title a couple months ago.
I've changed all of the fluids and filters, and I even changed out the muffler (the last one had a rusty hole in it the size of a football)
Since I live in California though, the vehicle has to pass smog. Last Monday I took it in to be tested, and it failed horribly.
One of the few pieces of paperwork I was left with was the results of its last smog test, which it passed in March of 2016.
The exhaust has a noticeably fuel-rich smell to it, which would indicate a cylinder not firing. I changed out the ignition coil, spark plugs, and wires, but it still failed smog.
I brought my RR to a local British auto specialist, who ran a compression test on the cylinders.
All of the cylinders came back at between 120 and 125 psi, but Cylinder #1 came back at 45 psi
The technician suggested that it's a crack in the cylinder wall, but I find this really hard to believe: wouldn't the oil come out milky/frothy?
I'm willing to bet it's something more straightforward like a blown head gasket, but I'd love to hear anyone's take on this
Thanks
