Mid Lifer

the ticking has definitely grown louder in the 500 miles I've had it. maybe the previous owner used Marvel Mystery Oil himself. I'll have to ask him. Next service won't be for a while as I've just had the 90k service done as a preventive measure, so the injectors will have to wait unless the MMO can do the job.

Thank you, the shudder is much more noticeable when maintaining a speed in the 30's mph, as you said. My temperature problem, which I thought was thermostat, is according to my Lexus service guy, a cracked cap on the coolant bottle. allowing a bubble now and then. He is advising I try Marvel Mystery Oil for the clicking. Any experience with it?

The transmission is giving me more of a shudder I'd say, from about 32 mph to 38 mph.

A newbie here, just bought a 1991 LS400, 100k miles. Looks like showroom new runs great but a couple of questions. Suspension seems soft, normal or time for struts/shocks? A slight ticking, which my mechanic said ignore and Lexus service said was fuel injectors has gotten a bit louder over the 500 miles I've driven it. Valves, or anything to be concerned about? Temperature rides at midpoint of gauge most of the time but occasionally kicks up to last mark before overheat, then slides back down. Could this be faulty thermostat? After sitting overnight, steering moans just a bit when backing out of parking space, then is OK thereafter. Finally, transmission seems to have slight vibration after shift to third, from 32-36 MPH, not noticeable when accelerating to highwat sped, just when maintaining speed in that range. I know that this is an 11 year old car. Am I just paranoid or should I worry about any of this. Thanks, Kyle
