Death rattle?

Oil consumption is good. The coolant looked slightly low, I topped it off.

 

Your good if it was new from Toyota.
Both parts.

 

parts are Toyota. So was replacing the brake booster, the same as sating brake traction or brake system?

 

The brake system is two separate parts.... the brake booster and the accumulator
both are connected together on the firewall

 

He is right about that but realize there are no new engines sold by anyone. Toyota would sell you a new “short block” which includes the main block with pistons rings and crankshaft. They would rebuild the head and use all the existing bolt on parts like the egr system, intake and exhaust. Probably $8k or more.

You do get a new head gasket because you have to buy a whole set of gaskets to put it together.

This is a serious sign if it continues to go down.

I like to recommend a professionally rebuilt engine like Hybridpit sells, shipped to your local small shop for install. It might be $5k by the time it’s done but this is as close to new as you can get for $4500-$5,000.

A gen4 engine uses much of your gen3 including egr system, exhaust, intake and requires modifications to your existing wiring harness and cooling system hoses. You would really need a unicorn shop that has done this a few times. Even then you would have a frankengine that most dealers would not work on.

The budget play is a genuine used in Japan JDM gen3 engine for $1200-$1500 plus a direct bolt in install. If you were lucky maybe $2500-$3000 all in. If you go this route be sure it’s a JDM engine and not a US salvage yard special.
