This will be the only modification necessary when performing the timing chain conversion. You got the book out, took pics and uploaded them. Ive bought 2nd hand petrol with 200 000klms in the last 2 months and was compiling a list of preventative maintenance to do straight up so i now it,s all good, apparently change the oil and filter,s about it, dunno, keep us posted if you do find any info mate, would be appreciated.

In 1975-82 the 20R through 22R engine used a double chain drive system. The timing chain problems are not uncommon, especially in high-mileage vehicles. Finally on the V6 no need to do anything with the timing chain but I would put a set of spark plugs in it. That version features not only the variable intake and exhaust valve timing system but also the significant changes in mechanical parts. Each cylinder has individual ignition coil integrated into the spark plug cap. And you're correct about the 100,000 mile change interval for the coolant. This failure is often diagnosed as a cracked head or a blown head gasket.
When I assembled the unit. This will save you labor costs later … on. Too much of that will eventually distort the guides' positions, forcing the timing chain to adapt to a route it was never meant to use. This is an interference engine, so failure to replace the belt and it breaks will result in severe engine damage. Now, let's see Bank 2 closest to the radiator.
Toyota recommends that you replace the single row chain every 70 to 80k miles. You will know the noise doesn't belong under the hood. The more they find wrong, the more money they can make lol. The chain will stretch beyond the tensioner's limits allowing the chain to slip against the plastic guides resulting in breaking the guides that's the noise heard on cold start up. I tightened the 3 bolts and then turned the center part by hand and it locked. When in doubt, ask TacomaWorld first! In a well-maintained engine a timing chain can last up to 300,000 miles and even longer. Align the two yellow links on the 2 timing chain to the timing marks on the new camshaft gears to ensure the exhaust gear is correctly timed to the intake gear.
He was lucky that the valve seat dropped and locked the motor, or it would have been a lot worse. The V6 uses a timing chain, no regularly scheduled maintenance for it. Often, if the timing chain is worn the engine may feel sluggish, low on power or have troubles starting. Unfortunately many dealers and shops believe the ladies know nothing about cars and try to capitalize on that. If the timing marks appear vastly out of alignment, turn the crankshaft one revolution 360° clockwise and note the position of the timing marks.
If the timing chain is worn, usually it's replaced as a kit with a new tensioner, guides, and other parts of the chain drive mechanism. Your '05 Runner is now 5. Don't worry about it as with regular servicing they seemed go for ever. It was this last, long trip that he was on, hat finally sealed it's fate. I am looking for any pick from the front so that I can see the relationship between the timing wheel and the crank. BlackWorksInc gets hold of colleagues and looks for someone doing a timing chain. It does say change the diff fluids if you have limited-slip, if equipped, but again it does not list the 4Runner in the footnote.
This is normal for this Forum. Providing a very dependable chain upgrade for a reasonable price. I'll check when i get off work and post up if theres anything helpful for you. If coolant is coming out the headers in the morning. And you're correct about the 100,000 mile change interval for the coolant. Let's start with the Bank 1 closest to the firewall cams tower not assembled and still off the head. The way I read this you have 60k or so on the synthetic presently in the t-case and axles.
This part is also sometimes called Toyota 4Runner Timing Chains. It proved to be very dependable and included steel timing chain guides. I now also have visual confirmation. Keeping the proper oil level will ensure that the timing chain is always lubricated. As far as the coolant and trans fluid I was informed that the coolant is long life 100,000 miles and the transmission is sealed, no filters, etc and does not need changed. I would consider doing it no later than in it's 7th year. If your truck is running like it always has for the last 112K miles, and isn't making any new strange noises, they're probably trying to take advantage of you.
No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.

To avoid timing chain problems you should maintain your engine properly and have the engine oil changed at recommended intervals. I wanted to do this, but they said not a good idea. The camshaft housing now is separate and the valves actuated by roller rocker arms with built-in needle bearings. With the addition of the dual row cam sprocket to the motor, the factory valve cover will now need to be modified to allow for clearance. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster.
I did not align the valve with the hole at first. Similarly to any other moving mechanical components inside any engine, a timing chain is subject to wear. Is the timing chain immune to mechanical failures? The timing chain is oiled by splash from the oil pan itself. It is attached to the valve cover by two spot welds. I would change it again. You can find this type of information in the service manual for your vehicle.
