I have a 93 legacy wagon my daughter purchased two years ago.Current mileage is 236,000 ...My Issue...The other day she said her car was smoking ALOT..
After looking closely, I discovered the radiator had about a four inch vertical crack on the front passenger side.The SMOKE she saw was obviously steam.It did have some significant oil leaks,so I did the crank and cam seals, replaced the radiator,put it back together and after I drove it around a while told her"here you go" as I thought it was running fine,just had a low idle and maybe a slight miss I had not noticed before...Sure enough,next morning I got a phone call..."My car is shaking alot"..So I drove the car home , seemed to have plenty of power.Parked it ,later that evening it would not start,changed plugs as old ones looked like original plugs..It did start,but shook terrible...finally got it running and warmed up only to notice STEAM coming from the exhaust pipe..........MY QUESTION IS ....Can I determine if the head is cracked without disassembly? I am not afraid of that, I just don't have a lot of extra time. Is there any way to determine if it is the head gasket instead?Do the "BLOCK SEALERS" work?
Thank you all for any response!!
