can you elaborate on this - while I'm in their . . .
"The while you were in there's are replacing the seals on the chain tensioners, also not too hard, and the o-rings on the oil bridges to the cam lobe oil rail, also not too bad."
You don't even have to do a partial drop. The thing that really gets in the way is the AC compressor mounting bracket. However I just did mine with the engine tin removed and loosened the bracket. Rear muffler will also need to be removed.
This really only works if you can get the stud behind the bracket to come out versus just removing the nut. The driver's side comes off no problem. Its the passenger's side that is the hassle.

Where are you located in the south exactly?
Do you mean the timing chain cover nut/stud? Seems the nut would come off with the bracket loosened slightly aft to provide clearance, but it would take much more clearance to get the TiChCov stud out.

Thanks.
Also - how long did it take you guys to drop an engine the first time?
Yes, the innermost cover stud on the passenger's side. The reason being is if you just remove the nut you still need to be able to pull the cover outwards, and there is not enough clearance to slide it out. You can remove the entire AC compressor bracket to gain the clearance, but for that you really need a special tool to remove the harmonic balancer from the crank.
Mine came out this way with not special coercion, but you might not have such good luck.
In addition to the timing chain cover leak, there are gaskets for the timing chain housing themselves which also leak and probably need replacing. You can mess with the timing in your car if you not careful with this. You can do this by removing the rear bumper and dropping the engine slightly, just loosen the rear engine mount bolts an inch or so.
Vice grips on the threads of the studs sounds ugly, but that is what was suggested to me here on RL somewhere. I ended up not having to go there because several of the studs came out with the nuts still attached.
I wish I could claim to be an expert on this, but im not. Have a look at some of the other threads on this subject. And yes, grinding off a marginal amount of material on the AC bracket doesn't harm anything...just make sure you paint it when you are done if you go this route..
I do not know the # for the harmonic balancer tool. I should note that my engine mounts were being replaced at this time as well, so the engine was easily manipulated in terms of height with a floor jack.

Thank you soo much for your write up on this. Probably saved me from doing the front cover gaskets and then going back and replacing the gaskets and Orings you replaced. Like doing the timing chain guide/tensioners '"while Im in there".

RicardoD, any tips on how to avoid messing up the timing while doing this work?
Seemed like his diy stopped at a timing issue and/or the timing chain tension so as not to change timing. He referenced literature for setting the timing. Of course you have to set both sides with the same timing.
