Subarian Posted December 23, 2005 Share Posted December 23, 2005 It's a very common problem. It's usually the hydraulic lash adjusters- HLAs- (the lifters). You can usually fix it by putting in a quart of marvel mystery oil and running it for a while at 4000 to 5000 rpm. Link to comment Share on other sites More sharing options...
Subieguy Posted December 23, 2005 Share Posted December 23, 2005 Could also be a bad oil pump or oil pump seal. A bad seal would cause the ticking. It lets air get sucked up into the engine and it will make the engine "tick". Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted December 23, 2005 Share Posted December 23, 2005 Hah this must be the season for the TOD (Tick of Death[light emphasis on death]). Ok, if it is coming from one side of your engine and the area of one cylinder, I'd bet it's a lifter. And you should change your oil to some cheap and light weight kind and substitute a quart of oil for a quart of marvel's mystery oil and run it fairly hard, not too hard for a while, the sound should go away. What this does is clear up and sludge or debris that might be blocking the oil ports. Once the sound goes away, do an oil change again with your normal oil. If it is coming from both sides of the engine, I'd say it's an oil pump problem...but check your oil filter, it may have collapsed (cheap ones do that). You can replace the oil pump seals, but when you are in there, check for any scaring of the aluminum from the brass(i think it's brass) gear. Keep us updated.

leonardator Posted December 23, 2005 Author Share Posted December 23, 2005 So if the engine is ticking and it's getting air in it, does that mean insufficient oil is getting into the engine and it's gonna eat itself up??? I will check if it is one side, or both tomorrow. thanks. Link to comment Share on other sites More sharing options...
rallyruss Posted December 23, 2005 Share Posted December 23, 2005 Could also be a bad oil pump or oil pump seal. A bad seal would cause the ticking. It lets air get sucked up into the engine and it will make the engine "tick". this is the most common. no harm in the short term. but the gasket should be changed. cleaning out the lifters can help sometims too.
