Problem Solved: Will write-up later: Need Help! - EGR tube re-assembly problem
Trying to solve the ol' Check Engine P0400 code - I jumped into two common DIY fixes I've crawled sites to research: replace dried/cracked vacuum tubes under engine cover and clean EGR tube. I'll provide a complete write-up when I solve the issue at hand:
Upon disconnecting my EGR tube from the top and lower and cleaning. NOTE: I could not get the one hex bolt by the oil filter loose because of angles/blockage by manifold, filter, etc. with Alan wrench or extension. I'm left with being unable to get the lower tube back into the intake hole. It's under tension and needs to be angled in a way I just cannot seem to achieve from top, front or bottom. Anyone out there who experienced and solve this?
This morning I got up and gave it a fresh go. I removed the oil filter, so I could remove the 5th hex retaining bolt and keep the vacuum end disconnected. This gave me enough movement to get the intake end back into the block and reduced the tension so I could squeeze together and start bolts. It's a PIA. I'll write-up my method, tools and contortions soon.
Feel pretty good about this DIY fix. Too soon to know if it solves the P0400 code or Check Engine. Will post after a couple drives.
Thanks!

Was your tube clogged up? I also have a '95 w/ 135k miles that I think will need a clean soon.

It's been a month since I cleaned the EGR tube and my Engine Check light nor my P0400 code has returned. It was a PIA job and I still owe some pics - but I think it's the cause of many high mileage cars.
