Hey guys. My 2000 Lexus GS 400 (4.0L V8) has been worrying me lately. It has 226,000 miles and still runs great. My concern is that on occasion when I go to crank the car after it has been sitting for a day or two- usually over the weekend, the engine sounds really rough when starting. Almost like a lower end clank noise. I am not a mechanic, but to me it sounds like the lower end of the engine is starving for oil.
It does burn oil (smoke at cold start up)so I try to ensure it always has enough oil. This morning it made that same clanking noise. I check the oil level and it was right at the minimum level. I went ahead and added a quart and after cranking it back up the sound went away.
Can any of you more experienced guys get me started on the right direction to fix this? I don’t want to put too much money in the car because it is not worth much as is, but I do want it to last me at least another year. Besides this issue- the engine is always chugging along like normal and very quiet.
Thank you in advance!
