My engine ticks intermittently...Always after starting and then it quits. I imagine it is the lifter pumping up. No url (oil for you city folks). Has anyone experienced this with any engines in the past? My engine has 124,000. Still strong and good compression. I see no need to scrap it yet. What should I do? Replace the lifters or use 50 weight oil or what? I'm not sure that replacing the lifters will do any good if the oil galley is clogged up any. How would I unclogg an oil galley anyway? I don't want to dislodge any other trash and create any more problems.
