175,ooo miles, $500:cheers:
oil was VERY black till i changed it AFTER this problem, changed to 20W 50
ok... got the jeep a month or so ago. ran fine till this... on interstate and went from no ac/heat to "vent". XJ died shifted to "N" slowed down to like 30mph or so then finally started back up. Engine now "knocks". Much louder when i first start it up. Then seems to settle out to a loud tick more than a knock as the engine heats up??? The knock/tick does increase in speed of knocks/ticks as the RPM's go up.
Also, when i turn on the heat the belt screames for a few seconds if i'm at idle. dont know if it's related? in fact dont know if the first time i went to vent is related. Just using the cause/effect mode to diag. the problem.
Any suggestions?
*O ya sounds to me like the knock is coming from the top of the engine
Have driven close to 100 miles or so with nothing getting worse.
Engine still as great power and "get up", no smoke, smells, etc
oil pressure is good..i think... little over 1/2 way (i think 40 is half?)
sorry for the long post, trying to give all details!!
