Question about Lexus LS 400

1 Answer

Burning much gas

I developed a bad oil leak at the front of my crankshaft. When I R&Red the crank seal, I accidentally scratched the crank nose while trying to pry out the leaking seal with a screwdriver. I can feel a burr. It is big enough that it took out a replacement seal in two minutes of running. The scratch is too far inside the water pump casting for me to see or easily access it. Someone suggested using a Dremel tool to remove the burr. I've also tried to locate a "crank saver" for the crank nose on the LS400 motor, but nobody seem to make one to fit it. Any suggestions or help locating a crank saver would be appreciated. Thanks, Art

SOURCE: Undertermined coolant leak location

core plugs they are called ,not freeze plugs and they are for the manufacture of the block to remove the casting sand.if you keep antifreeze in system they do not corrode not sure what engine in these things only ever seen one that i imported for someone and the paperwork for this was horrendous.look behind engine with a torch and a mirror and i have no doubt you are correct about the core plugs .only ever seen a diesel version .

SOURCE: water leaking bad from front of motor.

freeze plugs will be located towards bottom of the engine. It could be the water pump, or a bad hose.

SOURCE: oil leak problem with 1996 toyota camry

I am going to see a mechanic - my trusted mechanic who does not nickel and dime me - to see what this is. I have the same problem and he told me he has never done this job on a Camry and is unsure. Given the miles, he has suggested that maybe it is time to part ways with the car. I am going to ask him if he will put some florescent dye in it and let me drive it for 50-100 mi and then check to see where the leak is and fix it. Let you know what happens. I have to try, the car is solid.

SOURCE: My front crank seal is leaking can it harm my timing belt

Dear Calvin,

Just Have Your Front Crank Seal Replaced. The Water Pump Does not Need To Be Replaced At This Time. Try Taking It To Two More Mechanics. See what They Say. And Decide On A Fix.

Hope This Helps,

Alex :o)

Oil leak on driveway coming from front of engine

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    1998 camry oil smells like fuel, 260,000 miles. out runs strong, Just replaced the valve gaskets, can anyone help me figure out what's wrong?

    These engines do have chronic oil leaks onto the exhaust, hence the burning smell. When cam cover gaskets are replaced it is best to use the genuine Toyota parts, they seem to have some quality which lasts better.

    Other places which leak are the distributor shaft o-ring seal, and crankshaft nose seal, behind the timing belt sprocket. These can be replaced. The crankshaft rear main seal will leak, but is expensive, so just leave it.

    1995 Camry Oil Pressure Sender location

    Yes, is it the 4 or V6? I think it is either the oil pump shaft seal, or the crankshaft nose seal. The second one can be damaged by work in that vicinity such as removal of the crankshaft sprocket.

    The oil pressure sender is not at that location on the 4-cyl or the 3VZ V6, but on the 1MZ V6 it is on the front face of the engine block below the alternator mount.

    Will D15B engine encounter problem with crankshaft seal oil leaks at the place where the crankshaft is connected to gearbox?

    This is not usually a problem if the oil has been changed on a regular basis. These are pretty good little engines if the maintenance has been done properly. I have seen a few that burn oil badly, but I suspect it was because they were overheated after a coolant leak developed and wasn't repaired before further damage was done.

    My toyota vienta 3VZ-FE 1996 - oil leak onto exhaust


    That engine will leak oil from

    - cam cover gaskets (rear one drips on the exhaust)
    - camshaft end seals
    - distributor shaft o-ring (appears on top of transaxle housing)
    - oil filter bracket to block o-ring seal (drips on front bank exhaust)
    - crankshaft nose oil seal (have done with timing belt change)
    - rear main seal (expensive, leave it be)
