Still have my hands under the valve covers today, this time at the front edge of the driver’s side replacing the timing chain gasket. The timing chain cover made this a real pain to get to (that and I couldn’t get enough slack in the timing chain).
What should have be at most a 30 minute task took 90 minutes and a couple sets of hands.
Once we were able to get the gasket clear of the guide pins I pulled the half-moon seal, scraped the surfaces and put in a new seal and gasket.
