The RH Cylinder Head Cover of my 91 LS400 is borken. I used PC-Fahrenheit to repair but it did not work for me. I tried all the on-line Auto Parts stores and none of them list this part. Does any one know who might have the Cylinder Head Cover on sale? Thanks in advance.

I am guessing 105m miles = 105,000 miles. If this is correct and the car is in good condition, I am sure the price is good. I enjoyed my 91 ls400 until recently and it has 210,000 miles on it. Timing belt and wp: Don't do it yourserlf unless you know everything.

Interesting. Have you tried every shift position(3,2,1,)? If so, are they appropriate? Over drive off works, 2, 1 are working good!!!

I have been struggling to replace timing belt in my 91 LS400. When I finished the job and I was pretty confident that I had done a good job, but ... the timing was not right and car was moving fairly ok but gear change was not smooth. After three trial I made the timing good. Car runs smooth. But, alas, rear gear and neutral both move the car forward. In Drive, the car runs smooth and everything OK. Did I break the transmission? Any one can help me?

alsalih: Forgive me if you already know this, but make absolutely certain that you have the Cam Sprockets Locked (immobilized) before you remove the timing belt. Your engine is an interference type. If a Cam rotates because of valve spring pressure and a piston is "Up" (TDC) they will whack each other, probably resulting in bent valves (if you're lucky, that's all it will be). The best thing to do is to rotate the crank so that the crank timing mark indicates TDC and both Cam sprocket alignment marks are aligned with the marks on the front of each head. Then apply the Locks to the Cam Sprockets to hold them in place. You are now safe to remove the timing belt tensioner & timing belt. Do not rotate the crank, just install the new belt with the belt mark lined up on the crank sprocket mark & line up the Cam Sprocket marks with the belt marks. Re-install the tensioner. Provided everything lines up, you are now safe to remove the Cam Sprocket Locks. I changed TB myself and lost control of the orginal cam positions. My engine runs but bucking occurs at lower speed all the time. I tried but failed to identify the timing marks from the timing pulley. You wrote: crank timing mark, TDC, cam sprocket alignment mark, marks on the front of each head. Can you explain these marks physically where they are and how they look? You are the man who will free me from deep agony. :-)

I had same leaking problem recently. I visiually checked and found the leak was at rack side. In this case the concern of alternator is out of scope. My 91 LS400 has 200k mi on it and the rack looks expensive. Added leak-stop liquid($4) and it worked after 200 miles. I am not sure how long it will last. There was another weird thing I would like to share. Whenever I start the engine, the exhaust gas was really blue. Believe it or not, this began with leak and gone with leak stop. Exactly same time. Hope any one has answer to this. good days

Hi I am interested in purchasing one. I have a 91 LS400 and the LCD display failed totally after 3 years. It would help if you can send me instruction that shows how to replace the unit. I want to confirm one thing. When you said LCD Display, did you mean the whole unit? Or is it partially repairable? If you purchase qty of 100, then does it cost only $150 for the whole unit?
