Can't figure it out?

Asked by Sep 11, 2019 at 11:48 PM about the 1973 Pontiac Bonneville

Question type: Maintenance & Repair

My boyfriend is constantly going through gaskets
on his intake,there's a 400 size engine. Now he's
burning oil,and the transmission fluid smells
burnt,and white smoke out the tail pipe, and engine
is smoking by the time we get home from some
where.  He just put another radiator in,and when he
goes to pull out,if too fast,this metal jerking sound
comes from the back end. Please help.

Cars wear out, and I nearly fifty years this one has. White smoke from the tail pipe signifies coolant burning in the combustion process. Burned smell from transmission is from fluid left in too long and the mechanism is damaged. Burning oil is from worn piston rings and/or valve seals. Cost to rejuvenate this car would be many times what the car is worth. If you like this car, you could search for one that's similar on google or Hemmings Motor News or other old car sites; maybe even attend car auctions.
