Hello al I am new to this formum seeking some advice.
My engine suddenly blew and I don't know why.
My car is 2000 gtp odometer says 75k though I do wonder.
All maintenance done on time hoses water pump belts and therm changed.Had ne w rack and pinon bushings and oilpan gasket
changed. Car threw a p102 code about a week before motor went
Cleaned maf sensor...didn't fix

Planning to put a reman motor in. Friend will do install for me
But I want to find out why my motor blew in the first place so it doesn't happen again
Any ideas?? No smoke no oil leaks no coolant leak. Car seemed to run just fine

I have right around 3700 to either fix car or buy another.

Help will be greatly appreciated as I am a single mother with very limited funds

thanks in advanced.
