Toyota Camry

 

Year of car?

Does the part have wiring running to it? If so, what colors.

Is the part just sitting on top of the round can underneath or is it part of the can?

Who many hoses go to the part?

Off hand guessing its an electric solenoid valve (VSV). The valve controls vacuum on/off between the hoses connected to it to control the EGR system.

 

Make a chart of the bolt locations.

Unloosen one bolt at time in the reverse of installation. Feel for differences in bolt removal and for loose bolts. Inspect bolt threads for signs of aluminum from the block. Mark any bolt issues on the chart. You could also torque the bolts again as installed to check for loose ones. Torque to the initial toque spec not the turn bolt say 90 degrees to yield procedure.

Once the head is off inspect the threaded holes in the block and use the chart if suspect problems areas. Can make a fixture to simulate the head thickness and torque up each bolt. Use the old bolts for this job.

Not all bolt threads fail. An internet search would find what areas of the block typically have failed bolt threads.
