So, it was the universal joint and transmission mount that was the problem after all then.
Glad you & the son got that solved.
As to your list of other questions -
I think John has answered most of your questions as to the oil & filter, the DexCool,
brake fluid and adding any additives to your gas or engine oil. The only thing I've used
over the years to my gas, is Lucas fuel injector treatment, to keep the injectors free
from buildup, and for a fine spray pattern.
Maybe three times a year, I'm about to do it soon before the driving season gets underway.
I've not found any grease fittings on our cars, to my knowledge they didn't come with
any fittings from the factory. Occasional I will spray some CRC silicone lube, white
lithium grease to the rubber bushings, to keep the pliable in heat/cold and for their old age.
Seafoam is a no go for me. It is supposed to help with carbon build up on direct injection
motors such as the Redline model on the intake valves. For the base model Sky which has
a sequential port injection method, there still could be carbon build up, but nothing really
works on this unless- the intake valves are cleaned with a proven method of walnut blasting
the carbon build away. Chunks of carbon in the oil and in the turbo internals could be a bad
thing, so an oil change is recommended after use of this product.
The steering rack operation can be checked, if or when you replace the power steering fluid.
Unless there are issues with the rack itself, you should need to worry about it.
It is ok sorta, to overload us with questions for being uninformed about this car.
I've learned a great deal about this car- through other owners here on the forum
and their extensive knowledge about this car.
Thank goodness for the son to help you out- as it sounds like this car had issues
when it was put away 2 years ago. We all want our cars to be reliable and dependable.
But... with any mechanical item, parts do wear out, fluids do degrade, and lack of proper
maintenance by the owner operator can lead to a short life span.
So, you now have a new base line starting point for you at this current mileage on the
odometer for maintenance. As you change fluids or parts on the car going forward,
document them somewhere, for reference sake just in case the odd unknown
mechanic asks you when was the last time this was looked at question.
I do it, for my own personal reference and for the next owner of this car.
It is part of the car history. I had some info about the first owner and any
Maintenace done on my car before I bought it.
Last thing - make sure you as the new owner has a good roadside emergency contract
so you can call them 24/7 if anything goes wrong on the drive to & from work.
You don't want be left stranded or waiting for the son to bail you out from GA on
his next visit. Be prepared. Better to have it, and not need it, then to need it and
not have it.
* I might be able to go out today, for a pre-inspection tour on my car if the weather
holds true. Yesterday some very large farm equipment was here creating some havoc
before the planting season begins shortly. There was a rumble in my driveway long
before I saw them arrive. Rut Roh, I knew what was going to happen. The large green
JD dinosaurs will be back in about two weeks.
After that I can work in relative peace & quiet to the exterior/interior/engine bay spaces.
Happy motoring -
