What are the symptoms you are getting. Your engine is meant to run as smooth as anything after replacing

Alajiki:


The engine sound is louder than usual. There's also mild vibration.

Dear Nairaland Auto Experts,

I just changed my Camry 2007 engine. However, I've discovered that the new tokunbo engine does not run smoothly. Somebody asked whether they used the diagnosis machine on it after it was fixed but I said no. My question:

Is this a common occurrence after a change of engine? How can this be solved please?

I shall appreciate your valuable advice.

GAZZUZZ:


you bought a bad engine.

mayor2013:


Engine sound louder could mean exhaust was not properly tightened. Vibration could be as a result of wrong connection of some vacuum hoses. Make sure your connections too are done rightly

please take a clear pic of the engine number (on engine) and paste here, I will explain why you have the vibrations.

Oga,

That engine has been worked on.

the 'loudness' is most likely due to the aftermath of the 'valve grinding'

the valve grinding itself is not the issue here, but the interchanging of all the valve shims when reassembly of the top cylinder.

the valve train is now louder than usual as all valve clearances are most likely out of spec.
This is the part where i hate the 2AZ-fe engine! ( God bless the k24 abeg)

The vibration is may be most likely caused by the replacement piston assembly/ out of phase balance shaft during reassembly (they fit don commot am sef )

This might be a problem cos if that engine was from a 2007-up vehicle, the piston/ piston ring design is usually different from the earlier 2az engines, in that the one from an earlier one was used to rebuild that engine(due to easier availability)
The implication is that the one from earlier models are slightly smaller in length (depth). and even in diameter. this might cause the vibration and may even cause piston slap when engine is cold.


btw, is there any knocking/rattling noise present at either low or high rpms?

Post the vin number riveted to the engine block so that we may know the donor vehicle it came out from( but i no trust ladipo boys o )

e fit be 1az-fe
