Bryan Vs. L300 — Current Score = 6 : 2
Six new spark plugs are in, torqued, and ready to fire!
But not without sacrifice.
I was unable to remove one of the coolant hoses. It’s a very squishy hose from the throttle body to the block. It mates with the block at a 90 degree angle and was impossible to break free. After damaging the hose, I decided it was worth cutting it. I’ll need to get a new hose. That should run me about $10. Point Saturn.
But I was able to remove the intake manifolds, and get them cleaned, and that exposed the ignition coils and spark plugs. So I changed all six plugs. Six points Bryan.
In the process of taking off the throttle body (upper intake), I had to remove a pipe that routes exhaust back into the intake. It uses compression fittings on both ends of the pipe. I was unable to break the compression fitting free on the top side. Instead, the fitting spun on the pipe and the threaded coupling came out of the EGR regulator. Oh well, at least it came out and we didn’t have another incident like the power steering pump. No points, draw.
Then I went to do the thermostat…. I can’t get to it. My 3″ socket extension is about 6″ too short. Point Saturn.
Later today I’ll try and make a run to the parts store with Kylenes car, and see if I can get the hose I need, and the socket extension.
Here’s a bunch of photos I’ve been taking of the progress / work.
- Starting out…
- Removed Air box & MAF sensor…
- Throttle Body
- Rear (cyl 1 – 3 – 5) intake manifold. Notice underneath is a hose that’s been cut…
- This plug had 99,950 miles on it. I’m hoping it’s the culprit.
- Ignition coil top-side.
