What do you mean "I can see the white part" ? Do you have spark wire burn through, and is the the white stuff from the coil discharging to something other than the spark plug ?? If this is the case, it is probable that this cylinder is not firing since your spark is not reaching the plug...

It Works !!!!! Well guys, I got her all buttoned up today and she fired right up !!! I was REAL nervous, as I did not test the new starter out befor installing in the engine bay. Many,many thanks to Lex and Zuffen for their guidance. as I could not have done it without the help from you two...

My apologies. Zuffen had answered this question previously.... The torque settings are: * Rear waterbridge 18N-m or 13lbft. * Starter motor 39N-m or 29lbft * Lower manifold 18N-m or 13lbft Rgds, Mike

Can someone please help me out and tell me what the torque specification(ft-lb) is for the front and rear water cross-over bridge on a '99 LS400 ? Thanks in advance -Mike

Thanks Zuffen. Yes, I noticed that these water jacket gaskets are a high quality design. They are actually a 3 layer design with the silicon bead along the inner perimeter as you said. There are 2 thicker outer steel layers with a thiner middle steel layer. When I looked horizontally at the...

When replacing starter, I lost some coolant from the lines that run to the throttle body, and when I removed the rear coolant cross-over pipe. If I had to take a guess, I think I lost a quart or maybe 1/2 gallon at most. The coolant that is in there now is redish looking. Does Pep Boys...

New Starter Motor Installed Today was a busy day, I was able to remove the rear water cross-over bridge, remove the faulty starter, clean up all the nasty grunge that built up over the years under the intake, and finally install the new starter motor. Tomorrow, I need to go to Lexus dealer...

Making sure my rebuilt starter was identical to the old one The first thing I did when I removed the old starter was to make certain that the rebuilt starter was identical is all respects(ie same electrical connector type, same thread sixes for attaching bolts, etc. etc. )

Update: Old starter motor removed from car OK gentlemen, I finally got the old starter out of the car. Here are a few pics and embeded notes : . . . . . . Now it's time to see if I can get this whole mess back together !!!!! :D

Note about fuel line to intake Since I did not disconnect the fuel line from the intake, care must be taken not to move the intake too far forward. The flexible rubber portion of the fuel line is what allows you to move the intake to access starter motor. Of course the fuel line would have to...

update OK, another 3 hours of work. Remove the 10 lower intake nuts and bolts, and a few extra things to enable the intake assembly to be lifted and moved forward to reveal the start motor. Lex, you were correct in that the fuel line does NOT need to be disconnected. I was real happy about...

Will do and thanks for the quick reply. I am planning on removing the intake tomorrow. I have taken many pics of the process and would be happy to share with all. This LS400 is a monster compared to the usual engines I am used to working on..... ie Corvette LT1's and LT4's .... I have a...

OK guys, I am deep into it now....no turning back!!! :D I am at a point where I am close to lifting out the intake manifold. What worries me is that I don't think that I will have enough room to maneuver the manifold out of the way because of the 2 motor hooks and the fuel line, which runs...

Hey guys, I am in the process of replacing a starter motor in a '99 LS400. I have read the "How To" on this task by Lextreme, and also got some great advice from a couple of other members on this forum. After removing the TB ductwork and TB, I found myself staring at all the injector/coil...
