The NZ engines were introduced in They were designed specially for small class vehicles. The NZ consists of only two motors: a 1. The engine is designated for 5A-FE replacing. In contrast to its predecessor, a light aluminium cylinder block, a brand new crankshaft, pistons, connecting rods and others were used here. While making all that, a cylinder head with a VVTi variable valve timing system was run on the inlet camshaft.

Since the 1NZ hydraulic lifters have started to be assembled. It was necessary to adjust the valves at all the previous motors each 12, miles 20, km of mileage. The 5A engine was fitted with a timing belt.

The 1NZ engine has got a single-row timing chain with a 8-mm pitch of chain. In general, the engine is more like Toyota ZZ models. Nowadays the 1NZs are still being produced. The 1NZ-FE model — present is a basic motor.

It has It works by Atkinson cycle with a little bit delayed inlet valve closure. An updated model possesses a compression ratio of High oil consumption.

After running more thanmileskm of mileage, 1NZ engines can start excessively consuming oil. If that happens, you need to replace valve stem seals and piston rings. It is also typical of the 1ZZ motor. If any, your timing chain has been strained. That is common with engines running more than—miles—km of mileage. In order to handle the problem, you must get a new timing chain.

One also should inspect the timing chain tensioner. Rugh idling. If any, the problem can be solved by cleaning a throttle body unit and idle control valve.

Engine whistle. It is induced by a worn-out 1NZ alternator belt. You should check it. You should check engine mounts, especially the anterior one. If everything is alright, clean injectors and replace the fuel filter. That will help to eliminate vibrations.Some Toyota engines have timing belts, some have timing chains.

It pays to know what your engine has. There are no prescribed timing chain replacement intervals. To know if your car has a timing chain or belt watch the video where I explain how to quickly check. His high quality car buying tutorials offer help to the car buying public.

The 3RZ engine was designed for the off-road and commercial vehicles. It had a rather large displacement as for straight-4 configuration. This is due to the 95 mm cylinder bore and forged crankshaft with eight counterweights and 95 mm stroke. The 3RZ engine uses 2 balancer shafts, located in the crankcase. They serve to counterbalance the inertia forces of the second order. On the top of the cylinder block, the aluminum DOHC cylinder head with four valves per cylinder is mounted.

The diameter of the inlet valves is This head does not use hydraulic lifters, so you have to adjust the valves clearances after every 20, miles of mileage 30, km.

The valves clearances in a cold engine : 0.

The intake camshaft is driven by a timing chain. To increase the torque at low revs, the 3RZ-FE uses a long runner intake manifold. It also uses the multi point injection system and electronic spark advance ESA ignition system.

The firing order for the 3RZ-FE engines is This engine was being produced untillater it has been replaced by a new 2TR-FE. This is a rare case when the engine is designed without any serious flaws and faults.

The 3RZ engine construction is very simple and reliable. You just need to maintain it regularly, adjust the valves when needed, and use good quality engine oil and gasoline. In this case, you will never need major repairs. If your engine has passed overmileskmthen you should check the timing chain condition. It is durable, but aftermileskmit stretches and 3RZ knocking occurs. In all other respects, it is an excellent engine.

You can buy a cold air intake, short intake manifold, big throttle body, header and performance exhaust system. It is not too impressive, is it? It is installed on the stock internals and at a maximum boost pressure of 7 psi 0. The price of turbo kit is pretty good. Making more powerful designs using forged pistons, ARP head studs is a bad idea. It is better to buy 2UZ engine and make a swap. The supercharged 3RZ engine has a power of HP, if you use the stock 2. In this case, you completely remain stock internals.

It is durable, but aftermileskmit stretches and 3RZ knocking occurs. In all other respects, it is an excellent engine.The ignition system on your car has to work in perfect concert with the rest of the engine.

If the ignition system fires at the wrong time, power will fall and gas consumption and emissions can increase. This transformation causes the pressure in the cylinder to increase dramatically and forces the piston down. In order to get the most torque and power from the engine, the goal is to maximize the pressure in the cylinder during the power stroke.

Maximizing pressure will also produce the best engine efficiency, which translates directly into better mileage. The timing of the spark is critical to success.

If the spark occurs right when the piston reaches the top of the compression stroke, the piston will have already moved down part of the way into its power stroke before the gases in the cylinder have reached their highest pressures. To make the best use of the fuel, the spark should occur before the piston reaches the top of the compression strokeso by the time the piston starts down into its power stroke the pressures are high enough to start producing useful work.

And because the length of the stroke and the area of the piston are fixed, the only way to maximize work is by increasing pressure. The timing of the spark is important, and the timing can either be advanced or retarded depending on conditions.

The time that the fuel takes to burn is roughly constant. But the speed of the pistons increases as the engine speed increases. This means that the faster the engine goes, the earlier the spark has to occur. This is called spark advance : The faster the engine speed, the more advance is required.

Other goals, like minimizing emissionstake priority when maximum power is not required. For instance, by retarding the spark timing moving the spark closer to the top of the compression strokemaximum cylinder pressures and temperatures can be reduced.

Lowering temperatures helps reduce the formation of nitrogen oxides NO xwhich are a regulated pollutant. Retarding the timing may also eliminate knocking; some cars that have knock sensors will do this automatically. Can your car tell you when the light's about to change?

We will get through this together. Updated: October 10, References. In vehicular terminology, the distributor is an important part of a vehicle's ignition system. Most older models of vehicles contain a mechanical distributor, while more recent models almost always have electronic, computer controlled distributors or even distributor-less ignition systems. These modern distributors aren't terribly mechanic-friendly, but older mechanical varieties can be replaced and often are to improve engine performance.

See Step 1 below to get started! First, disconnect the plastic cap from the ignition, taking care to note where each wire goes so you can connect them to the new distributor in the right place. Make sure you also mark the position of the rotor before you remove the old distributor, since your new one will need to match up in order to start the engine. Then, attach the distributor with bolts or screws to the engine.

It's a Toyota Hi-Ace fromoriginally a 9-seater, nowadays pure transporter. I also know exactly why - because it's the most practical, reliable and fun to drive bus one can own. Afaik, the only other car that was equipped with the same block was a Toyota Hi-Lux, aka Tacoma, sooo ToxicGumbo, you got some time? Now here are the problems I need to fix, in order of their urgency: Documentation! Except for toyodiy.

This is bad. If you are able to help, you will be my hero! Diagnosis port How is this accessible and what information might it contain? Can I make anything blink me error codes by bridging some pins or something? Sounds like a rod bearing, so I suspect low oil pressure. What to check first? Where can I attach a pressure gauge? The engine bay is not so spacious see pic1I'd rather know beforehand where to look Economy light always red I'm not sure you guys from all around the globe know these lights in the dashboard, but Toyota has shipped their cars in Europe with them.

A long time ago, when it still worked right, it sometimes even went green when the gas pedal wasn't on the floor. For at least km, the light has always shown red. Only starts on second turn When the engine hasn't run for hours, it won't start on the first key turn. Once you can hear the fuel pump relais click off, give it another go and it starts just fine.

I suspect the fuel filter, which has possibly been in place for
