    heater problem - '95 LS400

    I know this topic had to be discussed in earlier forums, but my concentration is now on the heater control valve located on the eng firewall. I will list the series of events and would like to know if other Lex-heads had similar problems. 1. First of all, does the heater cont. valve ever get...

    There are 2 cam timing marks on the back plate

    Can anyone help me on this? One of the timing marks is noted with a "T"(I assume this is TDC), however the cams were lined up at a mark "before" the "T" mark when I removed the belt. Can anyone confirm which is the correct mark on the VVTI - '98 LS 400? Thanks in advance, although you're...

    Gloverman

    GLOVERMAN - I think I figured it out. When I first removed the timing belt, I noticed that both cams were lined up on another indicator mark, the one "before" "T" mark, but not on the "T" mark. When I put on the new belt, I moved the cams over to the "T" mark, could this be the source of my...

    Tps question

    Does anyone know if the TPS is only activated when the eng is warmed up? I think I may know why my vvti 1uz eng runs smoothly when it's cold, but idles erratically when it's warmed up. Here's my guess on what happened, while changing the timing belt, I pushed open the throttle valve by hand...

    Faults codes: 100, 110, 300,1346, 1351 - vvti '98 LS400

    Here's my problem guys: I've just changed the tb, cranked it up and it ran nicely at the startup rpms, once it warmed up the idle became irratic - fluctuating and almost dying out. I pulled fault codes: 100 (MAF), 110 (IAT SENSOR), and "pending" codes 300 (random multiple cyl misfire) code...

    Does the 95 LS400 have an oil cooler?

    Are there any hoses or connections in the rear of the engine that carries oil? I haven't had a chance to jack up the front so I can't see where oil is leaking from the rear of the engine. I can only see if drip down on the exhaust connection pipe flange, anyone have any ideas where it's coming...

    small oil and coolant leak '95 LS400

    I'm noticing a slow oil and coolant leak in the rear of the engine on the right bank. I first thought it was the infamous pow steering leak falling on the exhaust pipe causing smoking as the pipes get hot and burning off the oil. However, when I watched it while idling I noticed that oil &...

    HOW DO YOU ADJUST IGNITION TIMING?

    I've noticed on my OBD2 (active mode), my ignition timing is at 18-19 degrees BTDC on my '95 LS400, I know the timing should be in the 8-12 degree BTDC range. The shop manual instructs on how to check with a timing light, but it doesn't instruct on how to adjust. We have a lot of sharp Lex...
