Was finally able to put some time into the car.

Oil is now 10W30 and the cooling system is functioning like it should.

That is what I thought as well and I think I went to the 20W50 as my though has always been that thicker is better but I'm not sold on that.

With the remnants of Lee here right now, the car will...

It is a Q-jet.



If the odometer is correct (it has gone around once), about 120,000 miles. Cannot remember the exact numbers right now.

Like many said, I think the engine is just tired and...

I'll have to get that done at some point but may not happen before winter since I don't have the tester. I'm going to add a bottle of Restore like a few said before and see what that does.

It was about 7 minutes after it had idled for close to 10; it appears maybe the car was not hot enough :noidea: as I just checked the rad cap (which was cool to the touch before) and it is quite...

Ok, so I went for a quick drive and it ran just fine but no fluid in the upper rad hose still. Car is not running hot either. I'll check the rad fluid in the next couple of days too since I topped it...

I have the car back together and let it run for quite a while and it appears that I am still getting the blowby so I'm going to try Restore.

Maybe I will see if the parts store I am getting the valve cover gaskets from has a compression tester.

When I removed the old thermostat, I could open it manually but I guess that is not a real...

Well, I think that goes without saying. None-the-less, I see no evidence of coolant entering the cylinder(s).



One thing I did notice, and that is why I decided to do a few things, was that the...

Turns out that maybe the drive train was modified in the past because with them up, the rockers come in contact with the baffles so I put them on the bottom.

Apparently the car was low on gas (gauge does not work) as I ran out of gas on Thursday so that may account for starvation at WOT. Filled the car up and it still hesitates/bogs at WOT...
