Hi Venz

You should check that you are getting power to your glowplug busbar. (thats the alloy bar that connects the power to all the glowplugs).

1.Get a circuit tester and connect the clip to negative earth -
2.Get someone to turn the ignition key to "on" while you hold the tester on the busbar. It should light up for around six seconds I think.
3. If this happens all good than the next step is to check that the glow plugs are turning off correctly while your driving or operating the vehicle.

Also remove and inspect the glowplugs they should be just a nice brown/carbon colour...
They should have no chips out of them or damage of any kind.

These 4D56 engines have a glowplug timer that almost always stuffs out. Then they cause the glowplugs to stay on almost the whole time while driving which stuffs them quickly...

Let me no how you get on
I have a few easy ways to fix this problem!!!

PCV valve clogged, or far worse.causes oil likes

My lexus ls 400 model 1991 when start gray smoke ocurr for few second then disappear


the smoke is from engine oil, it is caused by leaking valve seals , after the engine is shut down for the day oil is leaking past the valve seals and getting into the cylinders then when you start up the engine the oil is burned off, this is a common problem, and there is a couple of things you can do to help the problem with out taking the engine apart and replacing the seals, try this first at your next oil change add some Restore to the engine oil it will soften the seals and give them a little more life, if this does not cure the problem after a few 100 miles then you will need to have the seals replaced, and this is a costly repair, but you could just live with the smoke it wont hurt any thing just keep an eye on the oil

Save you $$ and bring extra oil. When you do get a chance (downtime) then repair seal/gasket. Oil stop leaks are basically oil thickeners and nothing more. If they actually plugged a leak, they would also plug oil galleries and small oil passages and cause engine damage. Repair when you get the chance.

If leak is from top at rear my bet would be that valve cover gaskets are leaking. They are not too hard to change. Good Luck

My acura legend smokes if it stays in park for a while or if im at a stop light and start going it starts somking


It sound like you have oil leaking past the rings on your pistons. This is cause by normal wear and tear. You can tell for sure by taking the oil filler cap off while your engine is running. If smoke comes out, this is the problem. I would suggest going to your local parts store, they will help you find an oil additive to fix the problem.
