Engine swap question

One note to anyone else that sees the post and wants to do this. The “port” below the VVT solenoid is just the post the engine cover sits on. It is not open to the inside of the valve cover.

 

Yes. Gen 4 engine. There are open threaded holes on trans end of the engine. The Gen 3 engine in my car has studs in the open holes. Looks like just moving the studs around. All the sensors look to be in the same places with same connectors. I won’t be able to use the Gen 3 engine cover. And they could not find the Gen 4 cover that came off the one I bought.

 

I did pull the oil filter out of this engine. Very clean. Appeared to be OE filter. No debris in the oil that drained out. I saved it in a clean mason jar and poured it over a magnet. Since I’m putting 3, maybe four days into this, I wasn’t taking any chances.

 

Gen 4 coils are plug and play on the Gen 3. I pulled one off the Gen 4 I bought and plugged it in to my car. It fired across the plug gap. There is plenty of wiring as the Gen 3 coil for cylinder 4 is canted, but the Gen 4 coils have the connector pointing straight rearward.

 

The yard told me 8100 miles on the 17 this engine is out of. The plugs look great and the oil was very clean. I have not found any reason to doubt them yet. Looking at mine, I think I will have to reuse my intake, as they broke the map sensor off of the donor engine. Surprisingly they only cut the two hoses feeding the heater core. Every other coolant hose connection was just taken apart.

 

So the following realization just came to me. I want/need to get this done so I can take it to the local Toyota dealer for service. So I can see if they notice my Gen 3 has the heart of a Gen 4.

I think I might let them change the trans fluid just for kicks

 

At 430pm on Tuesday the fun begins. I don’t have to be back to work until Friday morning. Weather looks to be in my favor. I’ll be so glad to get my car back together.

 

Since the yard took the EGR cooler and manifold with converter, I’ll be reusing the Gen 3 items. Looks to be moving a couple of the studs around to bolt things back up. I have all the engine sensors except the MAP sensor that they broke off of the manifold. I looked into getting that sensor, but I will just reuse the Gen 3 intake. Im 92.5% sure that things will go according to plan. I still have a few things to look into, but I have to wait until my car is apart to see if things are going to work. The exhaust gasket matched the new one I had at work. If I didn’t have to work tomorrow, I’d get started tonight. I know that if I start, I won’t quit until it’s running.

 

I can literally have the intake off in 10 minutes without electric tools. The exhaust will be a little more challenging. Going to work on that tonight a little bit.

 

The intake does fit. There are some adjustments that would be required to use the Gen 4 intake. So I will use the Gen 3. Looks like I will have to change over the oil dipstick tubes between engines.

Since I had the wiper cowl off, I held my phone down and got a pic of the hole in my block. I can tell you that my engine threw enough oil to overwhelm my OCC. It was full along with my hoses going to it.

 

Absolutely bolting Gen 3 manifolds to it for photo op before installing the engine. If anyone seeing this has suggestions of pics to take, send me a PM or post them here. The more information I can provide will only help the next person doing their own swap.

 

I know that where I had my OCC hoses routed interfered with intake. And oil dipstick tube is bent differently. As far as design, I don’t know. Does anyone with a Gen 3 have the “replacement” intake noted on the TSB for the startup knock?
