You're current problem doesn't appear to be a "Hot Air Problem". If you have a Rod knock it is nearly identical to a Rod knock in a V6 in a 82 2bbl Regal, Sure, nobody rebuilds those anymore, but it doesn't mean they have forgotten how. You need to find an old guy who rebuilds buick motors, not a transmission shop that specializes in tuning '86/'87 Turbo Buicks,

Unbolting and bolting in a motor isn't hard. Throwing the motor in an old tire in the bed of a pickup and taking it somewhere is a lot easier/cheaper that towing a whole car around on a flatbed.

You could even haul a Buick V6 around on one of those $40 Hitch mounted racks from Harbor freight if you have an SUV and don't have a pickup.

Reading through your posts......I think you can save yourself a ton of aggravation (and $) by learning to work on your own vehicles.

I also have 3 kids around the same age. It is not uncommon for me to be wrenching out in the garage from 10-midnight....or early on a Sat or Sun morning. You'd be surprised how much an hour here and there can add up.

We live in a golden age of information....even an obscure car like an 84-85 hot air has a ton of info documented on sites like turbobuick. Imagine trying to address some of these same problems before the internet existed.....

I built my first 87 GN 3.8 in the mid 90s. I learned the hard way that the oil pump gears need packed with petroleum jelly after rebuilding or new oil pump parts. I eat up bearings because of dry starting it. Ever since, I prime all my oil pumps with a drill. I was told by a GM tech that the Buick oil pump design can get an air lock if not packed with Vaseline.

If my Turbo cars were sitting for a long time, I'd take off the turbo feed oil line and with little funnel, pour oil into the line until it was full, then hook it back up to the turbo, then start the car. The turbo feed line goes straight to the pump and this would ensure the pump was primed.

A Spun bearing usually isn't an oil pressure problem on a turbo car. Buicks have such low oil pressure anyway, they'd ALL have spun bearings if that were the case. Low oil pressure is a symptom of spun bearings. Antifreeze in the oil usually was the problem and slapping on some new head gaskets and selling the car to a sucker before it grenades was usually the "solution".

If the motor has a knock, the damage is done. The most likely cause of low oil pressure is the bearings are wiped. If you want to drive the car and not have it seize up to never turn over again after you shut it off from the next 25 mile drive you take it on (or break the crank or throw a rod through the block) the motor is going to need to be rebuilt.

Though heads look pretty clean, Like a previous owner blew a headgasket, washed down all of the bearings and the guy cleaned up the heads before bolting them back on.
