Greetings all. I just started the truck today and it sounds like there is no oil getting to the top of the engine. Was fine last night. I've read about timing chains and tensioners, but this sounds more like a rocker arm or lifter. Not a rattle of any kind, but a "clack, clack, clack" which coincides with engine rpm.
It's got 116k, and is always low on coolant. Have replaced the thermostat housing 3 times, but coolant still "disappears". I have to top off coolant about every 200 miles. It takes about a quart. Not sure if one thing has anything to do with the other, but engine is smooth even with this new noise (have not tried to move it. IT'S LOUD!). No milky oil, no back pressure in radiator, no excessive moisture in exhaust or steam.
I guess those are 2 different problems. The loud (diesel sounding) clacking is my main issue. Sounds like something is going to shoot through the valve cover! Any ideas?
