My 02/25/04 Post:
90-94 LS 400 ( Non-California )
Replacement Info:
From Beneath the vehicle:
Remove the two 12 mm nuts from the rt. side of manifold where the EGR pipe connects. (Good idea to have pre-soaked these with a solvent!)
Remove 12 mm bolt at the back of the block, visible by looking between the right side of the transmission and the exhaust. Note: This one sux!!
Above the vehicle:
Remove two 12 mm bolts at the top of the pipe assembly and slowly slide the assembly out by tilting it to the right.
-----------------------------------------------------
Addendum:
The bolt on the back of the engine above the transmission, (which did not appear on the schematic that I utilized as a reference) Sooner mentions in his directions is an absolute bastard!! Very little room between it and the firewall. I would by no means describe it's location as "visible".
3 bolts , 2 studs, 5 connection points total!
Reverse procedure to install new part.
-------------------------------------------------------------------------------------------------------------------
Note: The above is paraphrased from Sooners instructions below:
"there is 2 12 mm nuts on the right hand side manifold where the pipe connects to remove those next there is a 12 mm bolt in the back of the block to see this look between the tright sode of the trans and the exhaust remove this the go to the top remove the 2 12 mm bolts for the top of the pipe thin slowly work the pipe out tilting to the right.reinstall the oppostie way as posted this instructions are on for a 90-94 non californian car.and 95's r different".

I only got the top bolt of the upper 2 bolts off on my EGR pipe. I cant not get the bottom of the upper 2 bolts off. I gave up now and probably will try again tomorrow. I just can't get it. For those that have done it please help. 96 Ls btw. Thanks!
