thewzdoc Posted July 28, 2003 Share Posted July 28, 2003 Friday on the way home from work I stopped at a red light and noticed that the engine was running rough and I could hear what sounded like loud exhaust noise coming from the engine compartment. I drove home and parked in the garage. The next day I pulled it out to work in the garage and noticed engine oil, it’s never leaked before. I checked under the car and sure enough there is a wet spot where the engine and tranny meet. It still runs and shifts great but at idle it is still rough and it makes noise. Any ideas? (I really hope it's not a head gasket!) I’ve got an appointment with my mechanic this afternoon. Quote Link to comment Share on other sites More sharing options...
Lextreme Posted July 28, 2003 Share Posted July 28, 2003 Any smoke from the tail pipes? Does the car make excessive noise with quick turns? Any smoke from the engine? Check the oil dipstick and see if it look normal or not. Give us more info, so we can help u dx the problem. Quote Link to comment Share on other sites More sharing options...
ToddLS400 Posted July 28, 2003 Share Posted July 28, 2003 It could be your power steering fluid? That power steering pump is known to leak. It leaks ontop of the alternator and ruins it as well. Did you check your tranny fluid level? Maybe there is a gasket breech? Quote Link to comment Share on other sites More sharing options...
jsweb Posted July 29, 2003 Share Posted July 29, 2003 It sounds like the rear main seal. Mine went out on my 1992 at about 160,000 miles. Leaked oil slowly at first, then more and more until it got really obnoxious. Car started to run rough after awhile too. Cost me about $400 to get fixed.

thewzdoc Posted July 30, 2003 Author Share Posted July 30, 2003 OK.....The oil leak is the rear main seal. ($400 and some change). jsweb good job! The strange noise was the water pump eating its housing. The guy told me if it hadn't been a Lexus I wouldn't have made it to the shop. ($500 and some change, includes a new water pump from Lexus, timing belt, other miscellaneous items) It really freaked me out considering it has never leaked anything before (well it did leak PS fluid from a hose but that doesn't count) Quote Link to comment Share on other sites More sharing options...
jsweb Posted July 30, 2003 Share Posted July 30, 2003 Yeah, when it comes to broken things on my Lexus, I'm getting to be quite an expert. If you're experiencing it, I've probably been there...unfortunately. Johann Quote Link to comment Share on other sites More sharing options...
thewzdoc Posted July 31, 2003 Author Share Posted July 31, 2003 More news....One of the camshaft gears was missing teeth. Which, I guess, explains the knocking and pinging? The idler pulley bearings were so bad that they actually made noise if you shook the housing.... :( Thank gawd he is almost done....I can't afford any more "news". :chairshot: Quote Link to comment Share on other sites More sharing options...
Lextreme Posted July 31, 2003 Share Posted July 31, 2003 get a low mileage engine instead of repairing the cams. I have cams at home and other engine parts... Quote Link to comment Share on other sites More sharing options...
thewzdoc Posted August 1, 2003 Author Share Posted August 1, 2003 Oops I misunderstood what the mechanic was saying. The one cam was misaligned by 1 tooth (not missing a tooth). This was causing the knocking and pinging. Man it runs strong and quite now! And it only ran me $1300.00 New Lexus timing belt New Lexus water pump Rear Main seal New Lexus idler pulley and bracket New Lexus thermostat and housing Quote Link to comment Share on other sites More sharing options...
