Finally finished up the 120k timing service. This took longer than expected, since after finally getting the car back together I realized I had developed an oil leak. My suspicion was that it was the front crank seal, since I had placed the seal in further than I was supposed to, but decided to just carry on and hope it’d work. Anyways, long story short, my hope was misplaced and I had to rip down the front of the engine again and replaced the front crank seal. This time I was careful to keep it flush with the front of the oil pump. Additionally, I also put some Permatex Ultra Black around the outside of the seal before installing it. I had marked up the inside of the race a bit and was worried the leak could also have been coming from there.

Anyways, while I was doing this I also took the timing service, I also caught up one some other regular maintenance:

replaced the spark plugs
replaced some of the rubber hoses with silicone ones
cleaned & painted the timing covers
replaced no-name knock-off underive pulley with a Unorthodox Racing one
new accessory belts

For the timing covers, I went with a boring stock (but clean) look:
