87 GN needing some help

[stevestatix]

So with the heads off I am trying to clean all the fluid out. I didnt really want to go this far with a rebuild but I suppose I might as well.

Going to take the block off the tranny, put it on a stand and clean it all up. Inspect the tranny while im at of course. Take the oil pan off and replace the seal and whatever else I find in need of R&R.

Once I feel I did what I can I am going to get the parts I need and possibly if the misses lets me, put in an order for a new turbo and exhaust from Cotton. I am still disappointed with my first purchase but what can you do right. I will try to post some pictures of my progress.

Any input is always helpful

Sorry about the Doors tape, that sucks... don't get much better than the Doors.

Guess you're really digging into that thing... get some pics up, lets see that baby..

The pics of this project are way too big for the fourm. They will be posted on my facebook page if anyone is interested. Some of the shots are the parts that I am trying to get rid of or trade for some "in store credit", hint hint.

Hey everyone, just an update on the beast. Removed the block, took out the cam, crank, pistons, mains, timing cover, timing chain, Ect...

First things first, the timing chain only had one bolt holding it in and that was finger loose making the bolt hole hollowed out. New timing chain now needed.

The rear main seal was shot, the pistons are burned on top, the oil holes for the cam bearings were not lined up but i have read that some types don't require it. How can you tell though?

I don't know what to look for to make sure the components are good, like the block, rods, heads, pistons Ect...

I want to re use as much as I can to keep things original but don't want to miss something and have to take it all back apart. I saw a shop online called promar? Only $2500 for a complete motor shipped.

Any thoughts or ideas are highly needed. Thanks everyone.

Steve

Morning Steve,

I hate saying sorry, but sorry I didn't respond sooner, no excuses.. but either way, I'm back. I never was good on email, a phone call is always the best way to get my attention.. but even that can be an adventure..

If you are needing to build a motor and looking for options, I would suggest using either us or a reputable Buick V6 builder. These 2500 shipped motor are more than likely just a basic, as cheap as possible, non turbo motor. You spend considerably more for a legit motor, but it will be right with quality parts. The cam bearings will most likely have a groove on the back side allowing the oil to get to where it needs to be no matter what the location. The main parts you could reuse are the rods, crank and block, depending on what the pistons are. We pretty much use only the diamond pistons when we rebuild. Are you pistons stock or have they been replaced and if so, what bore and brand?

I will check the pistons out tonight. I have noticed a few spots with some metal on metal friction. I will identify all the parts tonight and post them up. Any news on the journal hole in the block. My main concern is oil getting in there and loosening the bolts. I do not believe the engine was bored. I will take a look at the last owners upgrades email if I can find it.
