Last year my dad made a mistake be sending our Toyota Crown 1991 5M carburated engine for a cylinder head rebuild to an unexperienced mechanic just because he charged cheaper.
The thing is after the job the car was:
-Noisier, sounded a liitle bit dirtier (Fixed by replacing exhaust manifold gasket)
-Car stalled when left running for about 20 min (Fixed by replacing the fuel pump)
-Now is the main part, the torque is lost and acceleration is very weak compared to prior the rebuild
My question is what could've gone wrong?
What did he do or didnt do that caused a severe loss in engine power
Valve lash adjustments?
Timing chain postion?
IDK but I would be grateful if you could predict what might have happened to cause this
have the same problem?
